Hi there. I am using the code from the code archives that "loads" an animated gif file then returns a variable called "animpic" (i think thats what its called!).

My question is - is the "animpic" a picture from which i need to grab sprites (if so how) or, how do I go about getting the frames so that my sprite will animate correctly?

Any advice would be appreciated.

Create your sprites/images/tiles of an equal size. Make another image the length and height times by how many you want in you sprite bank.

E.g say your seperate images are 32 x 32, and you wanted to store and use 20 sprites. Either have them as a strip 20x32=width, and height=32 will give you 20 equal spaces to put the gfx in. Or you could have them in a grid, ie 5 across by 4 down (5x32 = width, 4x32 = height). Just times the amount you want across and down by the size of the tile.

(syntax: LoadAnimImage("filename.extension",width_of_tile,height_of_tile,start(usually 0 - the first tile,how_many_tiles)

Now call them in blitz using your dimensions

Global graphics_bank=LoadAnimImage("graphics.gif",32,32,0,20)

;and use

DrawImage graphics,pos_x,pos_y,tile_number

Hope this helps you
