# JNebula v1.0.0 In-Dev
a component based graphics engine
coded in java
coded by: TheoW03
# Getting Started
No JSON editor
main
```JAVA
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
```JAVA
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");
}
}
```
JSON editor
warning: The JSON editor isn't fully functional and may have some bugs. or some specific test cases where
its unusable.
```JSON
[
{
"name": "render1",
"isActive": true,
"components": [
{
"component_name": "org.JNebula.Components.DifferentComponents.TransformComponent",
"location": {
"x": 100,
"y": 100,
"z": 0
}
},
{
"component_name": "org.JNebula.Components.DifferentComponents.SpriteComponent",
"file": "${path to image}",
"type": "jpg"
}
]
}
]
```
```JAVA
import org.JNebula.GameObjects.GameRenderer;
public class Main {
public static void main(String[] args) throws IOException {
GameRenderer starterCode = new StarterCode(); //for step 3 if you get a not defined error then
Window.InitWindow(640, 480, "example window", starterCode, "${PATH TO JSON}");
}
}
```
```JAVA
public class StarterCode extends GameRenderer {
//runs 1st frame.
//dt: delta time
//GL2: OpenGL context
@Override
public void start(float dt, GL2 gl){
}
//runs every frame.
// dt: delta time
//GL2: OpenGL context
@Override
public void update(float dt, GL2 gl){
GameObject render1Instance = InitObjects.Find("render1");
}
}
