[Mr.Fames]

Hello guys i have a script here and inside i am checking for if a player is in area or not if he is in then send him a message, my problem is the message keeps spamming my screen and crashes the game so how can i make it so when i enter the area the message appears once only once not more here's the code :

pawn Code:

public OnPlayerUpdate(playerid)
{
    for(new i = 0; i < MAX_PLAYERS; i++)
    {
        if(/* My Area Check */)
        {
            SendClientMessage(playerid, -1, "you are in");
        }
    }
    return 1;
}
