Custom healing ward

[emil23]

Hey how can i make healing ward ability healing one unit only once? IT heals unit instantly for x HP but only once IT cant heal again unless healing ward is casted again. Healing ward should also heal units WHO come to IT too or who are near IT. IT should heal every unit nearby but only once unless recasted.


I have some ideas for this spell but i think my ideas mąkę it too complained

So if I understand correctly, you want a Healing Ward that casts Holy Light or Heal for example, but it'll never target the same unit more than once?

For that I would use a Unit Indexer / Hashtable and a Unit Group array. So when you spawn the Healing Ward you would create a new Unit Group and link it to the Ward. Then whenever the Ward heals a unit, you add them to this "heal" Unit Group. You can then prevent use the Unit Group as a filter to prevent the Ward from healing the same unit more than once (If target is NOT in Heal Group then proceed to heal).

To handle the periodic healing you can add the Healing Wards to a single Unit Group and use a Timer/Periodic Interval + Pick Every Unit function to loop over them and look for nearby targets to heal. If the ward dies, remove it from the ward Unit Group and then destroy the "heal" Unit Group that is linked to it.

This is using Bribe's Unit Indexer. If you already have a Unit Indexer in your map then DON'T import the one from my map.
