In 2D Games shadow creation is simple than 3D. The only thing you must do is render the same objects with gray color and different orientation.

  1. Sprite - (0,0,0,0.5) multiply color so the shadow color is halt transparent black color.
  2. Sprite - (x+20,y+20,w*2,h*2) Light direction effects shadow coordinate and size.

	swRectSet(&shadow,xen->target.x+20,xen->target.y+20,xen->target.w*2,xen->target.h*2);
	swGraphicsSetColor0(0,0,0,0.5);
