There is an alternate approach to using a lock. this contact form

The consequence of this is that you cannot make OpenGL calls from other threads, because they do not have a current OpenGL context. Thank U very much.

Try setting the backgroundColor property of the window in the [CCAppDelegate setupCocos2dWithOptions:] method. If the action you needed to take were more expensive, you could also set a boolean flag when the value changed, and then only do the corresponding work in onDrawFrame() if Glclearcolor Color Chart All the RGB values are stored correctly, but the alpha value is always 255.So every render i clear the screen and then i render a model. Glclearcolor Alpha Perhaps you did not have the glColorMask for alpha channel writes enabled?Well, it also has the "feature" that it doesn't clear the color buffer unless told to do so.

Change the order of the two statements: first set the color, then call clear... And probably it uses the HDC of the window to create a p-buffer or perhaps a RenderBuffer so that rendering would work.

Then, it is just a matter of selecting a RGBA8 format instead of RGBX8 (Direct3D nomenclature). Powered by vBulletin Version 4.2.3 Copyright © 2016 vBulletin Solutions, Inc.
