public class HealCommand : BaseCommand { public HealCommand() { AccessLevel = AccessLevel.Player; Supports = CommandSupport.AllMobiles; Commands = new string[] { "Heal" }; ObjectTypes = ObjectTypes.Mobiles; Usage = "Heal"; Description = "Heals yourself"; } public override void Execute(CommandEventArgs e, IMobile from) { PlayerMobile pm = from as PlayerMobile; if (pm != null) { pm.Hits += 50; pm.Mana += 50; pm.SendMessage("You feel refreshed."); } } }This code defines a custom command called "Heal" which can be executed by players to restore 50 health and mana. The Execute method casts the "from" object (which represents the mobile that initiated the command) to a PlayerMobile and then modifies their health and mana properties accordingly. In terms of package library, this code is dependent on the Ultima Online SDK and would likely be included in a custom server implementation built using that SDK.
