hi
i have 2 questions:
1- i used on_esc=NULL but in fullscreen sometime when i hited esc key, engine was minimized. why?

2-i made a small dll .it must call in each frame and work fine in gs but , i have problem with fps.when it run , maximum engine fps is go to 20 . dll functions are not slow but fps is very low.
is there any tips/tricks for making dll?
has any one faced this probleem?

1. If the engine gets minimized (not closed!) when you press escape it cuold be that another program has got a hook on escape. Ensure on_esc is really null. You can do that by writing "printf("%d",(long)on_esc);" Another function could have set the on_esc pointer.

2. If calling the dll every frame causes a significant slowdown then that slowdown is of course caused by the plugin. If you comment the line out, that calls the dll function, does the fps go back to normal then?

thank you for your quick answer

1-i check my code and in just one line i set on_esc=NULL
and i write printf("%d",(long)on_esc); and now i can see a number (261153896)
what dose it mean?

2-yes when i comment call functions fps goes back to normal

3- why it stops on a very low fps (about 20 - 23) on a wide range of computers?
i test it with a very high configured pc and a medium pc . fps didn't change.
if i use a slow command , it must have better fps on high pc

thank you.

1. That's the address contained within the on_esc pointer. The number itself is not of interest. But that the number is different than 0 clearly shows that on_esc is not NULL. Why don't you post your code so that we can have a look at this together?

2. Well there you have your proof that the plugin is causing fps slowdown. It's pretty hard to guess why this is the case as I don't have any information on the plugin. However, when you call a function inside a dll that needs a long time to return then this function either has to do complex calculations, just wastes time idling around or is forced to wait for an IO operation, e.g. a network activity.

3. That is not necessarily the case. See above at point 2. Additionally the plugin could set fps_max.

Do you include default.c?

That was my first guess but the engine would just close and not minimize in this case.
