For instance, if I set: panel.flags = SHOW \| OVERLAY; if(panel.flags == SHOW) will be false regardless of whether SHOW is on or off, due to OVERLAY being on. How do I check if a certain flag is on, ignoring any other? ---------------------------------------------------- Also, I need a panel and a function to interact with each other. More specifically, the panel will have buttons that can activate the function, and the function might have to change the flags of the panel. This creates a problem of code order. Code: PANEL* superpanel={ button(blah,blah,superfunction); } function superfunction(){ superpanel.flags = SHOW; } superpanel doesn't know what superfunction is. I can fix this by putting this somewhere before the panel: Code: function superfunction(){} ...but I'm afraid that might be a very rough and hack-ish solution to this problem that may cause issues. Is this ok, or should I do something else? Last edited by Valdsator; 07/02/12 09:32.

Don't worry, it is the right way to do it (define your functions headers before you main function and implement them later). You can separate function headers and implementations in many files Best regards. Best regards. PhysX 3 Plugin Box2D Plugin

Edit: Would just like to mention that it seems panels don't care about whether they're defined before or after functions that they might have to call, so pre-defining them isn't required. But, knowing how to do this will definitely be helpful in the future. Last edited by Valdsator; 07/02/12 10:23.
