Replacing pixels in GM7 question

Is it possible to replace/changes pixels on sprites with code in-game?

MMF2, if you got the exact RGB values of a color on a sprite, you could replace all the identically colored pixels with a new color.

So like with my old Megaman 4 competition demo, the charge up animation was actually not an animation.  I just cycled through the ol' NES colors by changing certain pixels' colors every so often.

Just wondering if GM can do that.

It can, but doing it would not be easy, as far as I'm aware as gm doesn't use palettes.  Essentially what you would have to do is draw the sprite on to a surface, go through each pixel and draw over the ones that match, then save that surface to a sprite.

Edit: heres another way it can be done http://www.gmlscripts.com/script/sprite_replace_color

The function you're looking for is like replace_color() or color_replace() or something. It exists; I used it for my old Rockman and Protoman game from years back.

Yeah, in gm6. In gm7 you need to do it manually. There are ways, but they're very slow

Damn, I was hoping for a quick color switch for different tunics instead of having to essentially make more sprites that are the same as the others -.-
