Speedlimiter? - Carlito - 07.12.2009

Is it possible to make a speedlimiter with SetVehicleVelocity? u type /speedlimit 50 and u cant drive faster than 50kmh

Re: Speedlimiter? - Joe Staff - 07.12.2009

Of course it's possible, and it requires more math and less scripting skill.

pawn Код:
new pSpeedLimit[MAX_PLAYERS]={-1,...};
new Float:gTempFloat[4];
public OnPlayerConnect(playerid)
{
  pSpeedLimit[playerid]=-1;
  return 1;
}
public OnPlayerCommandText(playerid,cmdtext[])
{
  if(!strcmp(cmdtext[1],"setlimit",true,8))
  {
    pSpeedLimit[playerid]=strval(cmdtext[10]);
    return SendClientMessage(playerid,0x99CC9900,"  Speed Limit Set");
  }
}
public OnPlayerUpdate(playerid)
{
  if(pSpeedLimit[playerid]>-1)
  {
    GetVehicleVelocity(GetPlayerVehicleID(playerid),gFloatTemp[0],gFloatTemp[1],gFloatTemp[2]);
    gFloatTemp[3]=(floatsqroot(gFloatTemp[0]*gFloatTemp[0]+gFloatTemp[1]*gFloatTemp[1]+gFloatTemp[2]*gFloatTemp[2])*100)/pSpeedLimit[playerid];
    if(gFloatTemp[3]>1)SetVehicleVelocity(GetPlayerVehicleID(playerid),gFloatTemp[0]/gFloatTemp[3],gFloatTemp[1]/gFloatTemp[3],gFloatTemp[2]/gFloatTemp[3]);
  }
  return 1;
}
Tested and works to 80% satisfaction
*issues: May cause lag at higher player bases and higher pings. Occasionally it doesn't work and player will have uncapped speeds until completely stopped (as far as I can tell)

I think maybe my speed calculation is incorrect, but it seems fairly accurate.

I made this version and it worked fine. Not too much math in mine. :P

pawn Код:
#define MAX_SPEED 0.7
#define SLOW_FACTOR 0.7

forward Timer();

public OnFilterScriptInit()
{
    SetTimer("Timer",1000,1);
    return 1;
}

public Timer()
{
    new Float:x,Float:y,Float:z,veh;
    for(new i; i<MAX_PLAYERS; i++)
    {
        veh=GetPlayerVehicleID(i);
        GetVehicleVelocity(veh,x,y,z);
        if((x > MAX_SPEED || x < -MAX_SPEED) || (y > MAX_SPEED || y < -MAX_SPEED))
        {
            SetVehicleVelocity(veh,x*SLOW_FACTOR,y*SLOW_FACTOR,z);
        }
    }
}

I fixed mine and it's hilarious to drive a car off a building when the limit is 5km/h.

alright thx... its because i have speedcamaras (AddFlitspaal, a script here in the forum) and its hard to keep the same speed...
