Draw sprite with variable alpha transparency

edited July 2013 in General Posts: 66

I want the sprite image to fade in/fade out over a background - i'm sure it's obvious but i cant find how to do it...

More specific - i want to fade from one sprite to a second sprite in the same location, starting at 100% sprite a 0% sprite b and ending with 0% sprite a and 100% sprite b

Is it possible?

Thanks

    Try that



    --# Main -- test alpha -- Use this function to perform your initial setup function setup() data = {alpha = 255} next = 0 end -- This function gets called once every frame function draw() -- This sets a dark background color background(40, 40, 50) fontSize(50) text("touch me",WIDTH/2,HEIGHT/8) scale(4) tint(255,255,255,data.alpha) sprite("Planet Cute:Character Boy",WIDTH/8,HEIGHT/8) tint(255,255,255,255-data.alpha) sprite("Planet Cute:Character Princess Girl",WIDTH/8,HEIGHT/8) end function touched(touch) if touch.state == BEGAN then tween(1,data,{alpha = next}) next = 255-next end end
