[solved] Bug: flicker at fade in and out.

[Jeeper]

I have had an issue with my game for a long time where randomly It will get a bug and flicker while trying to fade in and out. It was just recently when I discovered that the game viewtopic.php?f=5&t=33349&start=0 Slimeball also has this issue for me. I wonder if it is something Löve specific, if there is some fix, or if its another variable that is messing it up (Like Windows 8 etc).

No issues for me with slime ball. Maybe you could try to replicate the problem, but I'd be willing to bet that your graphics card is at blame.

Made a quick video, http://www.youtube.com/watch?v=rNDNRIQ3 ... e=youtu.be.

My graphic card is; Nvidia GTX 660M 2G GDDR5 (if that is to any use).

I don't know about the quality ort of thif the card, I'm notgood with that sort of thing. But I know that's what it is.

You can get the slimeBall.love from viewtopic.php?f=5&t=33349&start=0

Can you actually reproduce the problem with the least code possible?

Looks like a missing/overflowed love.graphics.setColor() call to me.

Most likely. Video driver issue would've had constant flickering rather than on peak point only.

I'm betting that's it too. Try changing line 393 to the following:

Code: Select all

love.graphics.setColor(0, 0, 0, math.max(0, math.min(255, flashAlpha)))

It'll clamp the flashAlpha value between 0 and 255. See, if setColor recieves a number less than 0 or more than 255 it wraps so 256 becomes 0 and -1 becomes 255. Which results in the flickering you are seeing. So you need to clamp the flashAlpha variable to prevent this.
