Do it like this when a player chooses his team:

Код:

foreach(Player, i)
{
    if(team[i] == team[playerid]) // Checks if they're on the same team
        // "playerid" being the player that joined the team, and "i" being his teammates that should see him on the radar
    {
        SetPlayerMarkerForPlayer(i, playerid, 0xFFFFFFFF); // Marks him on the radar
            // 0xFFFFFFFF is a white colour, replace it with the color of the team he chose
    }
}

Replace team[x] with your team variable.
