Ghosting With Shaders

[Puzzlem00n]

Hey, haven't been on here in a while, huh? Well, I'll get right to the question. You see this thread here?

Well, I basically want to do the same thing he does, but that thread was from the before time, where shaders didn't exist yet! So, is there any way to make this simple ghosting with shaders? I've been looking around for an hour and I can't seem to find anything. Thanks in advance!

You really don't need (or want!) shaders, you'll just want to use a canvas.
Every frame you draw a mostly-transparent rectangle with the background color over your canvas, and then draw the new scene over it, that should give you a nice fading ghost.

Alright, if you say so! I'll give that a try!

I had double/triple buffering problems with this method a while back.

You weren't using canvases, TechnoCat.
