yeah it worked i should have know i forgot that when you use a .dat file all the pointers are void and you need to declare them thanks

ok now it runs but my bit map comes out as a red square like thing do i need to change the grahics or lower the bit on the map

never mind what i was seeing was just a fraction of the building i just need to scale it down

um is there anyway to scale your bitmaps or am i just going to have to draw it smaller??

stretch_blit()

Or you can just use smaller bitmaps.

one final question what function do you use to set what the invisible color is or if you could just tell me where i can find a dictonary of all the allegro functions and peramaters that would work too thanks

The "invisible color" is always 0 for 8-bit (the first palette entry) and pink (RGB(255, 0, 255)) for truecolor modes. You can't change it, though that might change in later versions of Allegro.

The "dictionary" is otherwise known as the API docs and comes with Allegro in several forms. HTML, TXT, you name it. Check the docs folder.

so dose it support 24 bit? and what do you mean 0 for 8 bit (black?)

By "truecolor", I mean 16bpp, 24bpp, and 32bpp. All three use pink as the transparent color. As for 8 bit, it's always color 0, which means the first color in the palette (palette[0]). It might be (and usually is) black, but doesn't have to be.
