There is a check for that inside.
PHP Code:
if(g_iBombPlanter != NO_BOMB_PLANTED && g_bBombExploded == false)
{
new iTopKiller = GetTopKiller(1)
ShowMVPMessage(iTopKiller, 1)
}
PHP Code:
// ===============================================================================
// bomb_explode - Called when the Bomb exploded
// ===============================================================================
public bomb_explode(iPlanter, iDefuser)
{
g_bBombExploded = true
ShowMVPMessage(g_iBombPlanter, 3)
}
