draw_collision_mask()

I made a script that draws a simple rectangular collision mask of an instance:

Expand/// draw_collision_mask(color)
//
//  Draws a collision mask of an instance as a rectangle
//
//      color       color of drawn mask
//
/// GMLscripts.com/license
{
	var color;
	color = argument0;
    draw_set_color(color);
	draw_set_alpha(0.1);
	draw_rectangle(bbox_left,bbox_top,bbox_right,bbox_bottom,false);
	draw_set_alpha(0.3);
	draw_rectangle(bbox_left,bbox_top,bbox_right,bbox_bottom,true);
	draw_set_alpha(1);
}

Re: draw_collision_mask()

This could be really useful for debugging and maybe effects too. The only thing I'd add is some code to restore global color and alpha values.

Welcome to the forums and thanks for the script.

Re: draw_collision_mask()

Does this work for rotated sprites?

Re: draw_collision_mask()

For sure it doesn't as draw_rectangle doesn't draws rotated rectangles.
