How to change all the colors of a sprite in SDL

Recommended Posts

Hi, I have been thinking for a while how to display collisions in the game that I'm developing. At the end I have decided to show the sprite in white flashing with the real frame for a couple of seconds, like many games do. My question is... is there a way to display a frame in a specific color in SDL? I wouldn't like to start duplicating all the frames in white color... That would be a lot. Thanks

If I understand you correctly, by "sprite flashing in white" you mean that pixels that aren't alpha / colorkey in sprite, cycle their color in order: normal color / white, yes? Or do you mean, just normal white rectangular border ("frame") around sprite?

AFAIK there's no special SDL function that will do the first one for you, so you should copy sprite in realtime to second surface (or precache it on startup) and use direct pixel access to change colors in two for loops.

uhmm... I thought it was going to be easier. Yes, what I meant was to cycle their color in order (normal color / white).

At this moment, I don't know what to do, maybe I should show collisions in a different way...

It shouldn't be too hard just the draw the bitmaps; just put into the editor and set the color to Black and white.
