I created a ball sprite and am using white as the color surrounding the ball. I set the dbSetImageColorKey(255, 255, 255); to make the white invisible, but doesnt seem to work. Ive tried other colors and same with no results. I put the command within the void game(void) function. I also tried placing within the void function i used to update and display the sprite and still nothing... I just cant figure out what it is doing this. Anyone got any suggestions?

Thanks!

well, i don't know why it doesn't work, but anyway, you shouldn't be using it, it is better to use alpha channels with images (using tga/png format(s)), you can find tutorials on how to make alpha channels for your images if you search on google, including your designing program's name

If you must use it, you have to use it before loading the image from file.

JTK, I did. I tried it before any possible call that was related to the sprite.

Hassan, I will definitely look into that...gotta solve this issue. =)

Thank you both for your information!

Once I saw a weird issue: dbSetImageColorKey worked when it was placed in the main function (the void DarkGDK() part) but it did not work when it was inside another function called from there (like your "game" function). Try placing it after the beginning of the main function, does that help?

I figured out how to use alpha channels on Gimp, so it works well enough. Thanks though.
