Getting Started

main

import org.JNebula.GameObjects.GameRenderer;

public class Main {
    public static void main(String[] args) throws IOException {
        GameRenderer starterCode = new StarterCode(); //for step 3 if you get a not defined error then
        Window.InitWindow(640, 480, "example window", starterCode,"");
    }
}


your renderer class

public class StarterCode extends GameRenderer {

    //runs 1st frame. 
    //dt: delta time
    //GL2: OpenGL context
    @Override
    public void start(float dt, GL2 gl){
        GameObject obj = new GameObject("starterObj"); // you can name it what you want
        obj.AddComponent(new CameraComponent(new Vector3(0,0,0))); //not required if you dont add it will default to 0,0
        obj.AddComponent(new SpriteComponents("sprite.png","png",null)); //the null is a color
        obj.AddComponent(new TransformComponent(new Vector3(0,0,0)));
        Scene.InstantiateObject(obj);
    }
    //runs 1st frame. 
    //dt: delta time
    //GL2: OpenGL context
    @Override
    public void update(float dt, GL2 gl){
        GameObject render1Instance = InitObjects.Find("render1");
    }
