hey i have been trying to figure out how to use semi transparent images in lua. i have my semi transparent image in png format, but when i use it in my game its opaque. if someone could tell me how, if its even posible, it would be greatly appreciated.

try use the alpha flag (opt. arg #8 to img:blit())

can u use that in an example? plz

here is what i im writing now

screen:blit(0,0,clouds)
so how would that look useing the alpha flag?

local U=nil ; screen:blit(0,0,clouds,U,U,U,U,true)

local im=clouds ;
screen:blit(0,0,im,0,0,im:width(),im:height(),true ) -- more reliable

It's opaque on Windows Lua Player, while it's semi-transparent on the PSP

..so (alphaFlag=true) means
PSP: blit semi-trans.
PC: blit opaque

?
