I have two bitmaps, and first is what is shown in screen, and second what is only in memory. There are objects shadow collision in memory bitmap, (for example tree is by color white and ground is by black). Is there any algorithms for this my problem? Certainly is, but where it is? If someone have an Allegro code for 2D-shadows, please mail me or simply answer to this message. Is there any algorithm web-page? G: Jarkko Kähkönen Jarkko DOT Kahkonen AT mbnet DOT REMOVETHIS DOT fi
