Rect2D Class

The Rect2D class is a object class and is used to define objects in games. Rect2D has a setPos and setSize function to set the position and size respectively. It also has a setColor() function to set color aswell a setTexture() function to set an image as texture. A Hitbox can be assigned to it through the setHitbox() function. It has a draw() function which must be called in the Game Loop to render the rect.

export class Rect2D{
	constructor(arcsci, pX = 0, pY = 0, w = 0, h = 0, cR = 0, cG = 0, cB = 0, cA = 0){
		this.arcsci = arcsci;
		this.x = pX;
		this.y = pY;
        this.prX = pX;
        this.prY = pY;
		this.width = w;
		this.height = h;
		this.r = cR;
		this.g = cG;
		this.b = cB;
		this.a = cA;
		this.texture = new Image();
		this.isTextureLoaded = false;
        this.hitbox = null;
	}

    ...

}

The Rect2D takes Scene2D which determines on which Scene or Level will this be rendered in. It defines it's x, y position and width, height of its rect as 0 by default. It also has prW and prY to store its previous position to use in collision logic. It then defines its r, g, b and a values to use as its color and texture to use as its texture. The isTextureLoaded variable decides weather the object can draw texture or not.
