change frame rate

[charles88]

Hi guys, at last I manage to set the frame rate to 32 FPS by using multimedia timer:

Code: Select all

#include <irrlicht.h>
#include <windows.h>
#include <MMSystem.h>

#pragma comment(lib, "Irrlicht.lib")
#pragma comment(lib, "winmm.lib")

         :
         : 
         :
int main()
{
         :
         :
         :
    while(device->run())
        if (device->isWindowActive())
           {
                          :
                          :
                          :
              DWORD myTime = timeGetTime();
              while(timeGetTime()<(myTime+30));
                smgr->drawAll();
                          :
                          :
                          :
     }
            device->drop();

   return 0;
}

However, there are still little flickers left. sigh...

PS: thanks jontan6 for your code, have tried but not working maybe I set wrongly.

Although my model doesn't pass through the wall, there are flickers when my model collide with it. My friend said the flickers are caused by the scene manager try to draw everything at a very high frame rate

I think your friend may want to look for another cause for that. Is there any chance that you could make your project (code and models) available, so that we can help you debug it?

so do I...

Anyway is this the correct code to disable culling and setNearValue()? sorry was not quite familiar with irrlicht.

Code: Select all

node->setMaterialFlag(video::EMF_BACK_FACE_CULLING, false);
cam->setNearValue(10f);

no, not correct...
try this:

Code: Select all

node->setAutomaticCulling(EAC_OFF);
cam->setNearValue(0.01f); // or maybe even smaller

Hi, sorry for my late response. Yes, we found the cause of the flickers, it was not the scene manager but the terrain map that we were using. After we changed the terrain map, everything worked like a charm. lol... thanks guys for all your help, and please pardon my poor debugging skill.

PS: Thx Acki, I've tried your code on the map, but it still didn't work (yeah, because of my stupid map).

Sleep(1000/30); // 1000 = 1 sec

before drawall()

maybe try simplify your scene next time to track down the problem easier

A note for posterity: this will not sync you anywhere near 30fps, since all Sleep() guarantees is that it will not return until sometime after the specified time.
