Note:After applying all these values to the player, the playerclass limitations of the player are applied. So if you set the health of the player over that allowed, by his/her playerclass, it will then be lowered to the max_health for that playerclass.Note:"lives" allows you to give/remove lives from players. This is only useful if the current map limits the number of lives each player has.- Add/Subtract grenades #1
