Just do something like this: Create a new global variable, like

pawn Code:

new IsInGunGame[MAX_PLAYERS];

When you join the GunGame, you set it to 1 for the respective player,

pawn Code:

IsInGunGame[playerid]=1;

Then you add in OnPlayerSpawn something like

pawn Code:

if(IsInGunGame[playerid]==1)
{
  SetPlayerPos(playerid,x,y,z);
}

Of course you need to set the variable to 0 also at the point you want the player to spawn normally again after the GunGame finished and you have to add it in OnPlayerDisconnect also and set it to 0 for the playerid.

Hope you understand me and I could help you a bit :P
