allowing you to create many different houses with little efforts.

Buy this package today and you will have your neighbor done in no time.

Digger - Caves & Overhangs

For a long time it has been very difficult to create caves in Unity3d, it's default terrain system was not designed for it, so one of the common approaches was to create 3d modles which would include the caves, holes, and similar structures to be placed into the scene.

This package by Amandine Entertainment, allows you to create caves in your scene very easily.

Buy it today, before it's too late (it's currently at a disccount)

Uso de #Resources en #Unity

En los videojuegos muchas veces resulta necesario poder agregar objetos a la escena bajo ciertas condiciones, por ejemplo en el caso de videojuegos RPGs con magias, el elemento que tiene la animación y las partículas que representan la magia, debería ser creado cada vez que se utiliza la habilidad, las balas por ejemplo podrían igualmente ser creadas programáticamente a la escena cuando se necesitan y destruirse (eliminar de la escena) cuando ya no se necesitan.

En Unity la creación de objetos se puede hacer con Resources.
Vea el siguiente video para aprender como crear y destruir objetos de la escena utilizando Unity.

Creando personajes para #videojuegos fácilmente

Crear personajes para videojuegos es un proceso especializado que requiere mucho tiempo y conocimiento, se requiere investigación, hacr bocetos, dibujar las diferentes poses, modelado, rigging y animación.

En muchas ocasiones no se posee todo este conocimiento, sin embargo, hoy día existen herramientas que nos ayudan a facilitar el proceso de creación de personajes a partir de plantillas, y nos permiten darles un cierto grado de personalización, cabe mencionar sin embargo, que estas herramientas no llegan a reemplazar la creación de personajes ya que el grado de perzonalización que le podemos aplicar es limitado si no tenemos el conocimiento especializado en creación de personajes.

En este video veremos como crear un zombie con Mixamo Fuse

A day with Mixamo Fuse, Substance Painter and Substance Database

Fuse is a modular 3D character creator application from Mixamo, it allows you to quickly created customized 3D characters.
Substance Painter is an application from Allegorithmic, as its name states, allows you to paint substances, and take full advantage of Physical Based Rendering.
Substance Database also from Allegorithmic is a collection of more than 1000 substances, which allows you to create a great variety of textured 3D models.

My first step was to create a Female Elf A in Mixamo and give it some basic clothing

Once I had the base model, I exported to OBJ.

Then I opened Substance Painter, created a new project importing the recently created OBJ file along with its textures.

Once setup I started to choose how to group certain sections such as belt and boots top section using groups, masks and layers.
This is what I was able to make in little time.

Basic "shoot to target" in Unity 3D

First, let's create a new Unity 3d Project, and select 3D.

Let's add a terrain GameObject-3D-Terrain.
Import Characters package Assets-Import Package-Characters, select all, and click Import.
Find the ThirdPersonController in the Project pane(use the search tool if you can't find it) and add it to the scene.

Create a Cube GameObject-3d Object-Cube. Name it ShootBox.
Create a Sphere GameObject-3d Object-Sphere, set its scale to 0.5 for x,y,and z. Name it BulletPlaceHolder.
Create a folder Resources.
Drag the two recently created objects into the Resources folder.
Create a Scripts folder.
Create three scripts: Bullet.cs, Player.cs,ShooterBox.cs, and add their respective code

Bullet.cs

using UnityEngine;
using System.Collections;

public class Bullet : MonoBehaviour
{
    private float Speed = 3.5f;
    public GameObject Target = null;
    // Use this for initialization
    void Start()
    {

    }

    // Update is called once per frame
    void Update()
    {
        if (Target != null)
        {
            float step = Random.Range(1,5) * Time.deltaTime;
            this.transform.position = Vector3.MoveTowards(this.transform.position, Target.transform.position + new Vector3(0,0.5f,0), step);
        }
    }

    public void OnTriggerEnter(Collider other)
    {
        Debug.Log(other.name);
        Player playerComponent = other.GetComponent<Player>();
        if (playerComponent != null)
        {
            int newHealth = playerComponent.Health - 1;
            if (newHealth == 0)
            {
                Time.timeScale = 0;
            }
            else
                playerComponent.Health = newHealth;
            GameObject.Destroy(this.gameObject);
        }
    }
}

Player.cs

using UnityEngine;

using System.Collections;

using UnityEngine.UI;

public class Player : MonoBehaviour {

    public int Health = 100;

    public Text HealthText;

// Use this for initialization

void Start () {

}

// Update is called once per frame

void Update () {

}

    void OnGUI()

    {

        HealthText.text = Health.ToString();

    }

}

ShooterBox.cs

using UnityEngine;

using System.Collections;

public class ShooterBox : MonoBehaviour {

// Use this for initialization

    private GameObject player;

    private float lastTimeShooted = 0;

    public int ShootIntervalInSeconds = 15;

void Start () {

        this.player = GameObject.FindGameObjectWithTag("Player");

}

// Update is called once per frame

void Update () {

        if  ((lastTimeShooted + ShootIntervalInSeconds) < Time.time)

        {

            GameObject loadedResource = Resources.Load<GameObject>("BulletPlaceHolder");

            GameObject newInstance = GameObject.Instantiate<GameObject>(loadedResource);

            newInstance.transform.position = this.transform.position;

            Bullet bullet = newInstance.GetComponent<Bullet>();

            bullet.Target = this.player;

            lastTimeShooted = Time.time;

        }

}

}

Add the Bullet.cs script to the BulletPlaceHolder prefab.
Add the ShooterBox.cs script to the ShooterBox prefab.
Add the Player.cs script to the ThirdPersonController in the scene
Create a Canvas object and add two objects to it: HealthLabel, HealthText
Go to the ThirdPersonController in the scene, in the inspector find the Health Text field below the Player script and assign the recently created HealthText object.

What is PTI Costa Rica all about?

PTI stands for the spanish translation of
Professionals in Information Technology(in spanish Profesionales en Tecnologías en Información)

It was created from a desire to work in videogame development and at the same time give back to the world by using and mixing the experience and knowledge I have gathered throughtout my life,
which includes skills such as programming, software architecture, pscyhology, social responsibility, and more.

I believe that videogames have the best potential to reach more people and to really engage them, and I know that in order to really fix any problem you need to solve it from its roots, otherwise the same problems will eventually appear again.

Many of the problems which exist in today's society have not been solved because there is still more to change from its sources.

Addictions for example, are often the symptom of other problems such as family conflicts, traumatic events, mental illness, rejection, among others.

Generally, society members don't know the root causes of someones problems, which eventually turns in the well known discrimination towards people in need of help.

Also, even with the programs that exists today which try to help people in need, these will not be enough as long as the behavior from society members towards this people don't change.
This behavior is actually one of the reasons for relapse.

And it is not that society members are bad, but that we have been educated in a way where we discriminate, where we fear what we don't know and where we don't go deep in the causes behind the problems. Even in our jobs, specially in IT related fields we are usually told "patch it", we'll deal with the root cause later, which generally does not happen.

I firmly believe that videogames work better where other programs have failed, because as mentioned before they can reach bigger audiences, because with games we can also simulate real life situations, and create challenging and engaging gameplay evoking desired emotions that cause the learned topics last for long and not be forgotten easily.

What is Zephyr 2D

Zephyr2D is a 2D RPG isometric videogame currently in development.
Initially conceptualized by Eduardo Fonseca from @pticostarica.

The game is about a nuclear accident caused by humans negligence.
This accident results in unexpected mutations in living beings on the planet, while humans are turned back in what you would call "cave men", the rest of animals in the planet are mutated in a different way: their natural abilities are strengthen, they receive the abilities of reasoning and talking.
3000 years after the accident humans have already evolved without memory of what really happened, but animals are the planet's dominant species, and have taken revenge against humans.
There is only one city left where humans reside, named "Chaos Land" where a young female lives,
her name: Zephyr.
Zephyr feels something is not right and that humans are more than what they think, she has spent all her live trying to figure out what is not right, without any luck, but her time has come, and her path will take her to an adventure with powerful enemies, and unlock the truth from the past.

Zephyr Fighting Apollo

Zephyr 2D is still in an early stage, where some of the main gameplay mechanics are programmed, and the art is in the works and soon to be updated in the live concept demo playable at our website

How to create videogames with no budget

As time passes and technology advances, new services and products are created, which facilitates many tasks in a lot of professional fields, game development is not the exception.

We have reached the point where you can create video games without spending a single dollar,
Warning: This does not mean, it will be easy or that your games will be successful, it however may work for you as a way to be introduce in the industry, create games for your own fun, or small prototypes(or Proof of Concepts) to share your ideas.

First let's see what we need to create a simple basic mini game

• An idea
• Development Tools
• Access to Internet

The Idea

Ideas are free, and an idea usually takes you to other idea. Inspiration is one of the keys to generate ideas and every persons has their different ways to get inspired, listening to music, reading books, meditating, talking to people are just a few ways in which people can be inspired.

Development Tools

A set of software that will create your game development environment.\

Concept Art

For concept are you can create it with tools such as Microsoft's Paint or Gimp

Gameplay

For gameplay you can use free game engines such as Unity or Unreal

Unity comes with an IDE(Integrated Development Environment) named MonoDevelop and you can also download Visual Studio Community Edition if you like it more. In future releases both engines will come with a version of Visual Studio already in the installers.

3D Models

3d Models can be create at no cost by using blender, or you can also download some from sites such as OpenGameArt.org, Archive3d, or TF3DM

For humanoids and a small subset of animals and monsters there are websites such as Mixamo, which allows you to even rig your own characters or download free rigged characters and animate them yourself, the website also offer a good portion of free animations.

Sound and Music

There are tools such as audacity which allows you to create your own sounds, or you can also download sounds from websites such as OpenGameArt.org, or Freesound.org

Marketing

Social networks such as Facebook, Twitter, LinkedIn, G+ are free and useful places where you can do your marketing for free.

What's the trick?

The fact that there are tools which help you do everything incurring it no cost, does not mean that you don't have to work hard.

You still need to learn about a lot of topics, and understand how technology and trends work, including human behavior.

If you want to create a good video game, it is usually not enough to just go download a game engine and start creating a game, first you need to learn about things such as storytelling, game design, level design, 3d modeling, rigging, animation, concept art, anatomy, human behavior, behavioural patterns, culture and gender differences, creation of sound, marketing trends, blog creation, websites traffic generation, programming, analytics, and way more.

But guess what! You can still learn and apply all of that for free!

Google allows you to find almost anything you need, if you get to know the right keywords to search for, Youtube has a lot of useful training videos in all of the topics mentioned before.

There is always very good free information in websites such as:

Gamasutra

GamecareerGuide

GDCVault

Detective Kids videogame idea revealed

Detective Kids is a videogame currently in development, it has the objective to enhance kids deductive skills.

The game is about a kid who decides to explore beyond so decides to go out of the nerighborhood, as time passes our kid realizes is already nighttime and that is los, without any idea of the way home, nor any persons nearby that could be asked for help.

Our kid's mission is to find the way home, but there are challenges in the way.
The kid will get hungry and need to find food
The kid will get sad and need to find ways to recover an emotional balance
The kid will get tired and needs to find safe places to rest.
The kid will need to follow the clues in the way that will unblock others, eventually revealing the way home.
The kid will be affected by nature events such as rain, and snow, and needs to find ways to protect from these.

The mechanics will cause kids to use their max potential, enhancing their abilities.

The game is currently in the works, implementing some concepts of the core functionality.

Here is a video showing a concept for camera view, city layout, and attributes gauges

Stay tuned to this blog to know more of the progress.

Algunos tips para la creación de videojuegos

La creación de videojuegos es todo un arte, de eso no hay duda,
necesita creativad, dedicación y muy buena planeación.

A la hora de hacer un videojuego existen una serie de elementos que se deben de tomar en cuenta, de manera que el objetivo se cumpla.

¿Cómo se hacen los videojuegos?

Existen muchas herramientas que ayudan en esta tarea, desde lenguajes de programación hasta Game Engines, estos últimos son software frameworks especialmente diseñados para la creación y desarrollo de videojuegos.

Entre los Game Engine más populares se pueden encontrar:

• Unity: http://unity3d.com/get-unity
• Unreal Engine: https://www.unrealengine.com/
• Game Maker: https://www.yoyogames.com/studio/download
• Cry Engine: http://cryengine.com/get-cryengine

¿Qué más se necesita para hacer videojuegos?

Una vez teniendo una idea, es sumamente recomendable hacer lo que se conoce como un Game Design Document(GDD por sus siglas en inglés), 

El Game Design Document, es un documento de diseño que describe el juego que se desea realizar.

La recomendación general es que este sea de al menos 10 páginas, dentro de su contenido habrán elementos tales cómo:

• Objetivos del Juego
• Game Script
• Conceptos de elementos del juego(personajes, mundos, niveles, pantallas, entre otros)
• Género del juego
• Controles (teclado, touch, mouse, acelerómetro, giroscopio)
• Requerimientos Técnicos
• Detalle de las herramientas a utilizar
• Detalle de los personajes(nombre, vestimenta, colores, voz, movimiento, personalidad, fortalezas, debilidades, miedos, estilo de pelea, tipos de ataque)
• Detalle de material de referencia(otros juegos, videos, películas, animaciones, etc)
• Métricas(tamaño de personajes, peso, altura, velocidad, distancia según el tipo de ataque)
• Tipo de cámara(2D, 3D, Frontal, Isométrica, Vista Aerea, etc)
• Detalle de los elementos del Heads Up Display(HUD)
• Detalle de Música, y sonidos a utilizar, y en que momento y situaciones del juego
• Elementos de combate(habilidades, daño, etc)
• Estrategia de mercadeo
• Recursos requeridos(Herramientas, recurso humano, capital/financiamiento)
• Duración estimada del proyecto
• Cronograma estimado del proyecto

El GDD puede ser muy simple o muy complejo dependiendo del tipo de juego que se quiera hacer, sin embargo es altamente recomendable tener al menos un GDD básico donde se plasmen los detalle de la idea del juego, de manera que se pueda recurrir al mismo cuando sea necesario, así cómo para no salirse considerablemente de las guías básicas que se pongan en este.

El GDD puede ser un documento de texto, aunque también existen herramientas para hacer el trabajo mucho más amenos. En nuestro caso se trabaja con la versión de steam de Articy:draft 2 SE
ya que permite tener una representación visual de los flujos en el juegos tales cómo flujo de pantallas, flujo de la historia, etc, así cómo adjuntos para todo tipo de asset y la versión de texto del GDD.

Para mayor información sobre el GDD, se recomienda este libro:
Level Up! The Guide to Great Video Game Design

¿Pero y cuando entramos a la parte divertida, el desarrollo del juego?

Una de las tantas razones para hacer el GDD primero, es para tener una idea clara de lo que se desea implementar, así cómo los recursos de arte necesarios, estos recursos pueden estar en su fase conceptual.

De esta manera ahora podemos comenzar a implementar un protitipo.

Que funcionalidad implementar primero, dependerá usualmente de los gustos, sin embargo, es preferible comenzar con tareas pequeñas y que tengan un efecto visible, por ejemplo, diseño de pantallas y/o mecánicas de juego básicas. De esta manera se adelanta un poco el prototipo y se siente que hay un progreso en el desarrollo.

Durante la implementación del prototipo, se descubrirán aspectos que deberán se modificados, es recomendable, mantener el GDD actualizado con cualquier cambio que se realice.

Conforme se vaya progresando y corrigiendo aquellos aspectos que presenten la necesidad, el prototipo irá tomando forma y se convertirá en un Producto Mínimo Viable (MVP por sus siglas en inglés)

¿Quiero hacer mi personaje pero no sé cómo?

Para la creación de personajes se utilizan herramientas especializadas para modelado, animación y rigging, algunas de las más utilizadas son:

• Blender
• Maya LT
• Maya
• 3ds Max

Sin embargo, todas requieren de un proceso de aprendizaje y dependiendo el tipo de personaje o elementos que se quieran modelar, se deberán utlizar técnicas específicas para tal proceso, adicionalmente para videojuegos, es recomendable hacer modelos clasificados cómo "Low Poly models".

Básicamente entre menos polígonos tengan los modelos, menos procesamiento y cálculos internos son requeridos, así cómo un menor uso de memoria, cabe destacar que menos polígonos también significa menor detalle de los modelos, es un balance necesario de tomar en cuenta y dependerá mucho del tipo de videojuegos y las plataformas sobre las que se planea correr el videojuego.

En PTI se ha probado una herramienta de Mixamo llamada Fuse, la cual permite a partir de plantillas, crear personajes y personalizarlos de acuerdo a las necesidades. También tiene una tienda virtual donde se pueden obtener modelos y animaciones. 

Esta herramienta es bastante útil si se tienen los recursos económicos para aprovecharla.

Aparte de las herramientas anteriormente mencionadas existen tiendas virtuales donde se pueden obtener modelos 3d, y algunos con rigging y animaciones, varían en costos desde gratis, hasta cientos de dólares.

Algunos de los sitios conocidos donde se pueden encontrar modelos, son:

• Turbosquid
• TF3DM
• Unity Asset Store (En caso de utilizar Unity Game Engine)
• Unreal Market Place (En caso de utilizar Unreal Game Engine)
• Archive3D

Cabe destacar que es necesario fijarse en el tipo de licenciamiento de cada asset, así cómo su facitibilidad de uso (muchos no estarán pensados para ser utilizados en videojuegos o en determinadas plataformas)

¿No sé programar, que hago?

Con los game engines como Unity y Unreal, es posible hacer pequeños videojuegos sin escribir una sola línea de código, y los respectivos mercados virtuales de dichas herramientas tienen recursos que aumentan considerablemente la calidad y tipos de juegos que se pueden realizar.

Sin embargo para aprovechar todo el potencial de las herramientas es recomendable aprender a programar en los lenguajes respectivos soportados por el game engine de preferencia, o aliarse con personas que tengan conocimiento en el área de programación y que preferiblemente (aunque no necesario) conozcan las herramientas.

OpenGameArt.org

El sitio OpenGameArt.org cuenta con una serie de recursos gratuitos especialmente diseñados para ser utilizados en videojuegos.

Sonido:

El sitio https://www.freesound.org/ ofrece una colección de sonidos bajo la licencia Creative Commons.

Substance Painter

La herramienta Substance Painter es un recurso sumamente útil para la creación de texturas para assets 3D. Básicamente se puede pintar cualquier material sobre cualquier sección del mesh. Esta herramienta combinada con el Substance Database ofrece una infinidad de posibilidades sobre los diversos tipos de texturas y combinaciones que se puedan hacer y en poco tiempo. Tiene un costo económico considerable, pero si se le saca provecho es una buena inversión y aumenta las posibilidades de recuperación de la inversión no solo en assets de modelado, sino también en los videojuegos al aumentar la calidad de los mismos.

Unity3D - Basic Gamepad setup

Here I'll try to explain a simple way to setup a gamepad to work in Unity3D.
First, we have to configure the editor(Edit->Project Settings->Input), by creating as many buttons as required create a name of your choice for each and in the value of Positive Button use "joystick button 0" for first one, then, increase the number accordingly for the rest.

This will create an axis for each.
Then we create our script, which we also have a Name.
This Name will later be set accordingly in the inspector.
The Actor field in the script is just a shortcut to simulate click a button of your choice, not required, but certainly a shortcut for my own purposes.

[Serializable]
public class GamepadButton
{
    public string Name;
    public Button Actor;
    public bool ButtonState
    {
        get
        {
            bool _buttonState =Input.GetButtonUp(this.Name);
            if (_buttonState)
                this.OnPressed();
            return _buttonState;
        }
    }

    private void OnPressed()
    {
        this.Actor.onClick.Invoke();
    }

    internal bool IsPressed()
    {
        return this.ButtonState;
    }

}

[Serializable]
public class Gamepad
{
    public GamepadButton Button0;
    public GamepadButton Button1;
    public GamepadButton Button2;
    public GamepadButton Button3;
    public GamepadButton Button4;
    public GamepadButton Button5;
    public GamepadButton Button6;
}



Then we add a Gamepad type property to our player's script

public Gamepad GamepadConfig;

which will allow us to configure it from the inspector

Notice that on the Name configuration we had used the same names as when configuring the gamepad in the Project Settings Input.

In my personal situation what I am doing is detecting which gamepad button was pressed and based on that execute the respective action of the Actor button.


I hope you have liked it and that it works for anybody.

As always, This is just a basic sample, I'm not an expert myself and there will always be much better ways to do things.
Feedback is always welcome

Unity3D - Easily Handling Player's Objectives

A really easy way to handle player's objectives in Unity3D, is by taking advantage of these features:

• Game Object hierarchy
• Using public fields in scripts
• Drag and Drop objects into public fields

With that said, this is what we can do:

1. Create an empty game object
2. Create a new child object per objective we want to represent
3. Move each objective to the corresponding position(To make it easier you can click on the cube in the inspector once you have selected the objective, this will show the icon and name of the object in the Scene view)
4. Attach a collider marked with trigger so that it does not block the player movement.
5. Create a custom Objective script which will contain it's Name, Description, and other aspects required to handle it's behavior, including the action to perform when collider is reached. One of the important keys here is that each objective would have a "NextObjective" field, which is of the same type of the script(Objective). This helps reducing harcoded logic strings to go into the next objective.
6. Create a Objectives script, which will contain a field for CurrentObjective and internally retrieves the list of all of the objectives in the hierarchy.
7. Attach the Objectives script into the player's object, and drag your initial objective into the CurrentObjective field

These are the sample scripts:

Objective.cs:

using UnityEngine;

using System.Collections;

using System.Linq;

using System.Linq.Expressions;

public class Objective : MonoBehaviour

{

    public enum ObjectiveType

    {

        Reach = 0,

        Talk = 1,

        Defeat = 2,

    }

    public enum ObjectiveStatus

    {

        Pending = 0,

        Achieved = 1,

    }

    public enum ActionOnReach

    {

        MarkAsAchieved = 0,

        PlayCinematic = 1,

        PlayAnimation = 2,

        SetTrigger = 3,

    }

    public string Name;

    [Multiline(10)]

    public string Description;

    public ObjectiveType Kind;

    public ObjectiveStatus Status;

    public GameObject Target;

    public Objective NextObjective;

    public ActionOnReach[] ActionsOnReach;

    public Animator animator;

    public MovieTexture ClipToPlay;

    public string TriggerName;

    private void OnReach()

    {

        if (this.ActionsOnReach.Contains(ActionOnReach.MarkAsAchieved))

            this.Status = ObjectiveStatus.Achieved;

        if (this.ActionsOnReach.Contains(ActionOnReach.PlayCinematic))

            this.PlayCinematic();

        if (this.ActionsOnReach.Contains(ActionOnReach.PlayAnimation))

            this.PlayAnimation();

        if (this.ActionsOnReach.Contains(ActionOnReach.SetTrigger))

            this.NextObjective.Target.GetComponentInParent<Animator>().SetTrigger(this.TriggerName);

        ParentScript.CurrentObjective = this.NextObjective;

    }

    private void PlayAnimation()

    {

        Debug.Log("On PlayAnimation: Not implemented yet");

    }

    private void PlayCinematic()

    {

        Debug.Log("On PlayCinematic: Not implemented yet ");

    }

    void OnTriggerEnter2D(Collider2D other)

    {

        if (other.tag == "Player" && this.ParentScript.CurrentObjective.name == this.name)

        {

            OnReach();

        }

    }

    public Objectives ParentScript { get; set; }

}

Objectives.cs

using UnityEngine;

using System.Collections;

using UnityEngine.UI;

public class Objectives : MonoBehaviour {

    public Objective CurrentObjective;

    private Objective[] PlayerObjectives;

    public Image CurrentObjectiveArrow;

    public Text CurrentObjectiveDescription; 

    void Start()

    {

        var objectiveParentGameObject = this.CurrentObjective.transform.parent.gameObject;

        if (objectiveParentGameObject != null)

        {

            this.PlayerObjectives = objectiveParentGameObject.GetComponentsInChildren<Objective>();

            if (this.PlayerObjectives != null)

            {

                Debug.Log("Succesfully found all player objectives");

                foreach (Objective singleObjective in PlayerObjectives)

                {

                    if (singleObjective != null)

                    {

                        singleObjective.ParentScript = this;

                    }

                }

            }

            else

                Debug.LogError("Unable to find objectives");

        }

    }

    void OnGUI()

    {

        this.CurrentObjectiveDescription.text = this.CurrentObjective.Description;

    }

}

This is just one way to do it, although it is not the only way, there are always other ways, some easier, some more complex, and complexity would be based on your game specific needs.
