 |

Hi,
Is there a psp sdk version of getTickcount or similar function that I can use to build my timer class? |

Are you unable to do even the most basic searching of the psp include files? Try grepping for 'tick' in the psp include files directory. You might even find a function you're looking for.

| Code: | int gettick() {
static timeval tv;
gettimeofday(&tv, 0);
return (int)(tv.tv_sec * 1000) + (tv.tv_usec / 1000);
} |
include sys/time.h |

I just made my own little GetTickCount function for when i was porting a Quake II MD2 Model loader to PSPGL instead of OpenGL.
I had something like:
| Code: |
int GetTickCount() {
return time()/1000;
}
|
Since the 'time' function returns the current second from that clock at GNU or where ever it said, i divided it by 1000 to get it into miliseconds as the key frame required it.
Oh and im just wondering if that would work. I was too lazy to go searching. |

Nope, not even close. Taking a second based timer and dividing it by 1000 gives you kiloseconds not milliseconds :)
Seeing as you obviously dont know how to use grep :P
#include <psprtc.h>
u64 tick;
u64 millis;
sceRtcGetCurrentTick(&tick)
millis = tick / ((u64) sceRtcGetTickResolution() / 1000); |

If you want you can use this function: int sceRtcGetCurrentTick(u64 *tick);
defined in "psprtc.h". It returns a time in microseconds.
Here is a sample how to use it:
| Code: |
#include <psprtc.h>
//return time in milliseconds
u64 GetTick()
{
u64 temp;
sceRtcGetCurrentTick(&temp);
return temp/1000;
}
void main()
{
u64 tick;
tick = GetTick();
}

edit : "bis repetita placent"... TyRaNiD and I have posted nearly the same post at the same moment! :D |

| Lol thanks guys. As for grep, I thought that was a kind of grape until two days ago so don't blame me. :) |
