I tried to make bounce command what moves vehicle up, Not SetVehiclePos

pawn Код:

if(!strcmp(cmdtext, "/bounce", true))
    {
        if (IsPlayerInAnyVehicle(playerid) && GetPlayerState(playerid) == PLAYER_STATE_DRIVER)
    {
    new Float:vx, Float:vy, Float:vz;
    GetVehicleVelocity(GetPlayerVehicleID(playerid), vx, vy, vz);
    SetVehicleVelocity(GetPlayerVehicleID(playerid), vx, vy, vz * 1.5);
    
    }
        return 1;
    }

But, it didn't worked in-game, Script was ok.... that cmd just failed...
help me...
