Transparancy not working?

[the underminer]

when I make this new color TitleGreen = Color.new(21,165,69,50)

And then do screen:fillRect(0,0,177,272,TitleGreen)
The underlying image wich I blitted earlier to screen is not visible, while the alpha value is 50. How come? transparancy blitting is available in 0.15, isn't it?

It doesnt work in 2.0 either.

That's just stupid. So there is no version that it works in?
I'll have to use a square image then

oh it works it just a 0 - 1, On and off. the % transparency must be in the image itself. Its not done through the luaplayer.

So you're telling me if I go into Photoshop and create a half-transparent green screen 480x272 and blit it to Lua Player with transparency on, it'll work?

I find this highly unlikely.

Hmmm, works for me. If you use this code to fade in and out, it will fade in and out by using transparency and Im on 0.16 (I think).

The code I posted is unaltered and is made by Soulkiller BTW. I tested it in some altered form but it works.

Code: Select all

credits = Image.load("backgrounds/credits.png")
fader = Image.createEmpty(480,272)
alphaValue = 255
faderColor = Color.new(0,0,0,alphaValue)
fader:clear(faderColor)
while true do
screen:clear()
screen:blit(0,0,credits)
screen:blit(0,0,fader)
if alphaValue > 0 then
alphaValue = alphaValue - 5
else
break
end
faderColor = Color.new(0,0,0,alphaValue)
fader:clear(faderColor)
screen.waitVblankStart()
screen.flip()
end
screen.waitVblankStart(300) -- pause so it dosn't fade in and then imdeiatly fade out
while true do
screen:clear()
screen:blit(0,0,credits)
screen:blit(0,0,fader)
if alphaValue < 255 then
alphaValue = alphaValue + 5
else
break
end
faderColor = Color.new&#40;0,0,0,alphaValue&#41;
fader&#58;clear&#40;faderColor&#41;
screen.waitVblankStart&#40;&#41;
screen.flip&#40;&#41;
end

Its exactly what Im saying, PNG files are quite usefull to display transparancy. Full but not partial. Douchebag.
