Camera2D Class

The Camera2D is also a object. It can be used to explore big Scenes. The way it works is that it updates the CameraRectX and CameraRectYinScene2D. All rendered objects for example Rect2D` uses it to calculate its world position when drawing itself.

Here is how the Camera2D constructor looks:

export class Camera2D{
	constructor(arcsci, pX = 0, pY = 0){
		this.arcsci = arcsci;
		this.x = pX;
		this.y = pY;
	}

    ...

}

The Camera2D takes a Scene2D so it knows which Scene to render. It also takes in optional position when being initialized. The position of Camera2D can be changed using the setPos() function and it must be rendered using the view() function in a Game Loop.
