[HELP]TextDraw Problem[HELP]!!! - Cjgogo - 10.07.2012

So,I am making a speed system for vehicles,but the problem is that when I enter a car the speed bar doesn't shoow up,here's the code:

pawn Код:
forward UpdateSpeed(playerid);
new uSpeed;

new Text:vSpeed;

stock GetPlayerSpeed(playerid, bool:kmh = true)
{
    new
        Float:xx,
        Float:yy,
        Float:zz,
        Float:pSpeed;

    if(IsPlayerInAnyVehicle(playerid))
    {
        GetVehicleVelocity(GetPlayerVehicleID(playerid),xx,yy,zz);
    }
    else
    {
        GetPlayerVelocity(playerid,xx,yy,zz);
    }

    pSpeed  = floatsqroot((xx * xx) + (yy * yy) + (zz * zz));
    return kmh ? floatround((pSpeed * 195.12)) : floatround((pSpeed * 136.66667));
}//WARNING:This works for vehicle also,event if the name of the function is not relevant :P

public OnPlayerStateChange(playerid, newstate, oldstate)
{
    if(newstate == PLAYER_STATE_DRIVER)
    {
      new vString[128];
      format(vString,sizeof(vString),"Speed:%d",GetPlayerSpeed(playerid));
      new Float:x,Float:y;
      vSpeed = TextDrawCreate(x,y,vString);
      TextDrawAlignment(vSpeed,3);
      TextDrawColor(vSpeed,COLOR_WHITE);
      TextDrawFont(vSpeed,0);
      TextDrawShowForPlayer(playerid,vSpeed);
      uSpeed = SetTimer("UpdateSpeed",1000,true);
          if(oldstate == PLAYER_STATE_DRIVER&&newstate==PLAYER_STATE_ONFOOT)
         {
        TextDrawDestroy(vSpeed);
        KillTimer(uSpeed);
     }
   }
   return 1;
}

public UpdateSpeed(playerid)
{
      new vString[128];
      format(vString,sizeof(vString),"Speed:%d",GetPlayerSpeed(playerid));
      new Float:x,Float:y;
      vSpeed = TextDrawCreate(x,y,vString);
      TextDrawAlignment(vSpeed,3);
      TextDrawColor(vSpeed,COLOR_WHITE);
      TextDrawFont(vSpeed,0);
      TextDrawShowForPlayer(playerid,vSpeed);
      return 1;
}
Sp,that's all?Can anyone tell me why isn't working?Please help me asap.Thanks in advance.

You shouldn't destroy the textdraw, just hide it. and use TextdrawSetString.

Well,I did everything you said,it still doesn't show,anyone else?

Re: [HELP]TextDraw Problem[HELP]!!! - Vince - 10.07.2012

SetTimerEx.

OK,thanks for trying to help,I used SetTimerEx now,but..,the speed bar still doesn't show!

At top add
pawn Код:
new Text:vSpeed[MAX_PLAYERS];
new uSpeed[MAX_PLAYERS];
pawn Код:
public OnPlayerStateChange(playerid, newstate, oldstate)
{
    if(newstate == PLAYER_STATE_DRIVER)
    {
      new vString[128];
      format(vString,sizeof(vString),"Speed:%d",GetPlayerSpeed(playerid));
      TextDrawSetString(vSpeed[playerid],vString);
      TextDrawShowForPlayer(playerid,vSpeed[playerid]);
      uSpeed[playerid] = SetTimerEx("UpdateSpeed",1000,true,"i",playerid);
         if(oldstate == PLAYER_STATE_DRIVER&&newstate==PLAYER_STATE_ONFOOT)
         {
        TextDrawHideForPlayer(playerid,vSpeed[playerid]);
        KillTimer(uSpeed[playerid]);
     }
   }
}

pawn Код:
public OnGameModeInit()
{
    for(new i=0;i<MAX_PLAYERS;++i)
    {
      vSpeed[i] = TextDrawCreate(x,y,"_");//Replace X,Y with coordinates.
      TextDrawAlignment(vSpeed[i],3);
      TextDrawColor(vSpeed[i],COLOR_WHITE);
      TextDrawFont(vSpeed[i],0);
    }
    return 1;
}
