Use Physic on Scene

Javity Physic based on Box2D. You can easy create physic GameObject and handle collision or trigger events. This is example scene:

public class Scene0Bulider implements SceneBulider {
	@Override
	public void buildScene(Scene scene) {
		JGameObject polygonPhysicObject = scene.instantiateGameObject(new Vector2(200, 280));
		polygonPhysicObject.addComponent(new SpriteRenderer("atlas/images.atlas#babel"));
		polygonPhysicObject.addComponent(new Rigidbody());
		polygonPhysicObject.addComponent(new PolygonCollider(new Vector2(-50, -50), new Vector2(-25, 50),new Vector2(0, 50),new Vector2(25, 0),new Vector2(50, -50), new Vector2(-50, -50)));
		
		JGameObject circlePhysicObject = scene.instantiateGameObject(new Vector2(100, 200));
		circlePhysicObject.addComponent(new SpriteRenderer("atlas/images.atlas#babel"));
		circlePhysicObject.addComponent(new Rigidbody());
		circlePhysicObject.addComponent(new CircleCollider());
//		logo.addComponent(new ChangeScene());

		JGameObject rectamgPhysicObject = scene.instantiateGameObject(new Vector2(50, 250));
		rectamgPhysicObject.addComponent(new SpineRenderer("atlas/images.atlas#babel"));
		rectamgPhysicObject.addComponent(new Rigidbody());
		rectamgPhysicObject.addComponent(new RectangleCollider());

	}
}

When you create Physic GameObject you must add:

• Rigidbody component
• any Collider component like RectangleCollider/CircleCollider/PolygonCollider.
