Hello! Little tiny opengl problem.

getfox · 11-20-2008, 08:35 AM

I know this is stupid problem to ask for help on, but I'm not sure how to make my opengl view see through, I've messed around with all the glBlendFunc options, and I set glClearColor with: (0.0f, 0.0f, 0.0f, 0.0f); the last value being alpha. But it's still black?

Any help would be great. Thanks.

Code:

yourGLView.alpha = 0.5f;

Thanks Smithdale. That kind of worked and didn't, with 0.5, everything was alpha which was a bit of a problem but I noticed the black disappeared rather then fading. So I tried self.alpha = 0.998f; and this got rid of the background while leaving everything else pretty much the same. Perfect outcome I guess. I'm not sure why that works but hey thank you.
