Well, I recently downloaded DarkGDK and when I began to code my program, I created a small sprite with a magenta (255,0,255) background.

Now, I want this background transparent, but, when I use the following function:




Nothing happens to the image.
This is my current code:




I'd be grateful if anyone helped me.

Try moving your dbSetImageColorKey () ahead of your dbLoadImage() call.

OK, so I tried it in three different positions ( before the first dbLoadImage, inside the loop before and after the sprite creation) and it still didn't work.

I also noticed that in the template for Dark GDK - 2D game it does exactly what I'm trying to do - loads background, sets image color key, then creates a bunch of sprites.

The only other thing I can offer is that maybe your "transparent" portion isn't precisely <255, 0, 255>.

It is 255,0,255, I'm pretty sure. I used Photoshop CS2 to edit the file.

Oh.

Thanks! I'll try that out right now.
I'll edit here with the result.

EDIT: IT WOOOORKS!

Now I only have to figure out how to make the pixels EXACTLY 255,0,255 (all the pixels around my sprite are a mix of yellow and pink )

EDIT 2: I just realized I could've just used a transparent background when creating the image on PSCS2. >.>

EDIT 3: I can't get the sprite to move... the function I'm using is



any suggestions?
