Slowly declining FPS #139723 07/05/07 22:16 07/05/07 22:16

On initial startup, it's running at a near-perfectly stable 75 FPS, which is great for me. But, as the program runs (even when nothing is being changed or moved), the FPS gradually drops towards about 40 FPS. Anyone know why this could be happening? Code: void main() { cout << "I am MrCode,"; cout << "hear me roar!"; system("PAUSE"); }

I think I may have answered my own question. I'll see what I can do to optimize my code. Thanks for the tip! One thing, though: How would you use the debug panel to fund out how many loops are running? EDIT: ok, I went through it, removed some of the superfluous while-loops (like the ones controlling the GUI themes), replaced some of the while(1) with while(mouse_left== on), and it seems to run at 75 FPS longer. But after a while, the FPS still drops to 60. I can't change how the program deals with the background color, because that has to be able to change dynamically. Same with the GUI color, I had to leave it as a while because then it wouldn't be able to be interchangeable with the GUI themes. I don't know if there's anything else I can do about the FPS. If I can, please post about it (unless I figure it out first, then I'll post, ). Last edited by MrCode; 07/06/07 01:49.

How do you check whether a function is running or not through code? This is so that I can stop the other functions when the window test is running so that the script doesn't run redundant functions every time I want to go to and from the window test. Code: void main() { cout << "I am MrCode,"; cout << "hear me roar!"; system("PAUSE"); }

This is probably what is known as a "memory leak" (in general terms), and is probably the worst kind of bug, because it could be almost anything. However, with A6 and script, you dont have to bother with so much stuff like in a C++ program, so it shouldn't so hard to track down. Sphere Engine--the premier A6 graphics plugin.
