Hi ,

i really did not know the bug in the next function

Code:
char  fpsview='FPS %d';
byte  StringFPS[255];
dword FPS;
dword LastTime;

procedure FPScalc()
{
  FPS++;
  GetTickCount();
  Eax -= LastTime;
  if(Eax => 1000)
   {
    LastTime = Eax;
    wsprintf(@StringFPS,@fpsview,FPS);
    FPS=0;
   }
}


StringFPS variable is always hold a fiexd string as '!@'

any help please.

Code:
char  fpsview='FPS %d';


='FPS %d'; is a pointer

try

Code:
char* fpsview='FPS %d';


then pass it directly without @

alternatively

Code:
char fpsview[7];
strlcpy(@fpsview, 'FPS %d', 7);

btw you could probably do a better job without using wsprintf

Code:
char fpsview[255];
dword FPS;
dword LastTime;

procedure FPScalc() {
  char buf[32];
  FPS++;
  eax = GetTickCount();
  eax -= LastTime;
  if (eax => 1000) {
    LastTime = Eax;
    
    strlcpy(@fpsview, 'FPS: ', 6);
    IntToStr(FPS, @buf);
    strAppend(@fpsview, @buf, 255);
  
    FPS = 0;
  }
}


something like this.

ok it works.

but seems there is a logical bug in that function because it always hold '1' , it should hold
the frame per second of the animation.

LastTime = Eax;

this is it probably, since eax already has sub the lasttime etc, it is no longer gettickcount value

try

Code:
char fpsview[255];
dword FPS;
dword LastTime;

procedure FPScalc() {
  char buf[32];
  FPS++;
  ecx = GetTickCount();
  eax -= LastTime;
  if (eax => 1000) {
    LastTime = ecx;
    
    strlcpy(@fpsview, 'FPS: ', 6);
    IntToStr(FPS, @buf);
    strAppend(@fpsview, @buf, 255);
  
    FPS = 0;
  }
}

  edx = GetTickCount();
  eax -= LastTime;
  if (eax => 1000) {
    LastTime = edx;
    
    strlcpy(@fpsview, 'FPS: ', 6);
    IntToStr(FPS, @buf);
    strAppend(@fpsview, @buf, 255);

the string is growing after each second

for example
Code:
FPS: 61
FPS: 6161
FPS: 616161
 ........... etc
