   Hi,

   I'm getting sometimes hangs when in the Director.m the sentence

   glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT) is run

   I do not want to comment this out, cause I need the glClear in the game menu. But when in game, I have a background image and I don't need that glClear is called.

   How can I stop to run glClear but only when I am in game?

   Thanks

   glClear() is needed to clear the screen. else you will draw over the old screen.

   Hi riq,

   I have seen in the older newsgroups that glClear can not be needed if you have a background image filling everything (that's my situation). Also that this will be a speed enhacement just in this special situation. Is this right?

   Anyhow I'm having ocasionally hangs in that glClear, don't know why.

   I suggest to investigate why glClear is hanging your application.
