what is problem in that script ?

PHP Code:
fpslimit()
{
    self endon ("disconnect");

    kick_level = 0;
    fps_time = 0;

    
        while(isPlayer()) 
        { 

        self.fps = self getFps(); 

        if(self.fps < 250)
            fps_time = 0 ;
        else
            fps_time ++ ;
        if(fps_time == 5){
            if(kick_level == 0){
                self iPrintLn("com_maxfps must be set to 250 or below 250");
                wait 2;
                kick_level ++ ;
            }
            else{
                userid = self getEntityNumber();
                self iPrintLn("com_maxfps must be set to 250 or below 250");
                wait 2;
                kick (userid) ;
            }
            fps_time = 0;
        }

        
    } 
} 

its for while a player connected(there is not wrong here , only above script have infinite loop)

PHP Code:
Init() 
{ 
    level thread MonitorPlayerConnect(); 
    level thread OnFrameUpdate(); 
} 

OnFrameUpdate() 
{ 
    while( true ) 
    { 
        fpsNextFrame(); 

        wait( 0.05 ); 
    } 
} 

MonitorPlayerConnect() 
{ 
    while( true ) 
    { 
        level waittill( "connected" , player ); 

        if( !isDefined( player ) || !isPlayer( player ) ) 
            continue; 

        level thread OnClientFrameUpdate( player ); 
    } 
} 

OnClientFrameUpdate( player ) 
{ 
    player resetFps(); 
}
