i dont know anything about your gamemode (how teams are stored)

pawn Код:

public OnPlayerDeath(playerid,killerid,reason)
{
    if(gteam[killerid] == gteam[playerid] && killerid != INVALID_PLAYER_ID)
    {
        SendClientMessage(killerid,COLOR_RED,"You killed your teammate!");
        // code here , example SetPlayerHealth(killerid,0);
    }
}

this topic should be in scripting discussion
