I dont really understand what you are trying to do, but to find all players of a single team (losing team in this case) you would use a for loop to cycle through all of the players, check there team, and if they are on the losing team, print a message to them.
Heres an example...
Code:
#define T_TEAM 2
#define CT_TEAM 3
new iMaxPlayers = GetMaxClients();
for (new i=1;i<=iMaxPlayers;i++)
{
new iTeam = GetClientTeam(i);
if(iTeam == CT_TEAM)
{
PrintToChat(i, "This message only goes to the counter terrorist team");
}
}
This is just an example. Dont copy paste it, but it shows what I mean. You will want to have the team defines at the top (not even sure if those are right, they might be backwards) and have a function like PrintMessageToLosers() and pass the losing team index to it, and then print to them.
