help with making objects transparent

[Michael]

hey people
im working on "keep the helicopter up " game
u know.. u gotta click 2 make it go up and dont click 2 let it go down and make sure it doesn't touch any obsticles on the way

for the helicopter i'm using a small JPG image.. the problem is.. that image has white background and i want my turing background to be a different color
i want to make the pic transparent but turing doesn't support GIF
are there any other ways?

go into f10 and look up:

Pic.Draw and look at "PicMerge"

and to set the transparent colour, use Pic.SetTransparentColour

code:

var picID : int := Pic.FileNew ("pic.bmp") Pic.SetTransparentColor (picID, yellow) Pic.Draw (picID, 0, 0, picMerge)

look at the jpg before running the prog
