Healing Zone

Needs admin to load: it changes players’ health with the Set Player Damage gate, which only an admin can place.

Stand in the zone and your wounds heal a little every second. Turned around, the same chip makes a zone that hurts.

You need

• a brick with an Attached Zone covering the healing area

zone "Zone Ref" -> chip room

Code

// Damage healed per tick of the zone.
const HEAL = 10.0
// Seconds between ticks.
const EVERY = 1.0

@left in room: zone

var inside: character[]

on Clock(interval = EVERY) {
  inside.fillFromZonePlayers(room)
  for p in inside {
    let hurt = p.GetDamage()
    if hurt > 0.0 {
      p.SetDamage(max(hurt - HEAL, 0.0))
      p.ShowStatusMessage("Healing...")
    }
  }
}

Wire it

1. Compile the chip and paste it in-game, as an admin.
2. Wire the Attached Zone’s Zone Ref to room.

Check it in game

• Get hurt first (a second copy of this chip, made into a hurting zone as in Change it, can do that), then walk into the zone: once a second a status message says “Healing…”, and your health climbs back.
• Stay in the zone at full health: no message.
• With a second player: both of you heal at once.
• Walk out: the healing stops.

Change it

• Change HEAL and EVERY for faster or slower healing.
• Make a hurting zone: use p.SetDamage(hurt + HEAL) and drop the if hurt > 0.0 check. A player dies when their damage reaches the limit that p.GetDamage().DamageLimit reports.
• Heal only players who carry a tag: pass it as inside.fillFromZonePlayers(room, "medic"), and give players the tag with character.SetTag("medic"), from a button for example.

How it works

The Clock fires every EVERY seconds (Reacting to the Game), fills a list with the players standing in the zone, and loops over it (Looping Over a List). A player’s health is kept as damage taken: 0 is unhurt, and GetDamage() reads it. max(a, b) gives the larger of two numbers, so healing never takes the damage below 0. The list is filled again on every tick, so a player who walked out is no longer in it.
