Chain Spell Template

This map contains a single chain spell which is easy configurable, even if your a beginning coder.

Variable are:
- Missile Speed
- Bounce Range (the maximum range that the missile will search a new target to bounce to)
- Number of Bounces
- Maximum Hits (how much times a unit may be hit by the same bounce spell, warcraft default is 1)
- Missile Type (a unit that is created in the Object Editor)
- Ability type (the one that is casted every time the bounce hits)
- The conditions that a unit must meet to be aquired as the next target (example: currently it only picks enemy units)

Code (map example is a Storm Bolt chain)

The idea is good and the triggers have no leaks or make over problems so you get 5/5 from me. :thumbs_up:

First of all, Thanks gods I'm not alone who uses the Hashtables.

Now triggers.
I can see that your loop trigger's interval is too short (MIN interval should be 0.03).
You HAVE to turn your loop trigger off sometime. With many loop-triggers it will start lagging very soon.
I'd suggest to use this in the Cast trigger
  • If ((PowerChainGroup is empty) Equal to True) then do (Trigger - Turn on Chain Storm Bolt Loop <gen>) else do (Do nothing)
  • Unit Group - Add (Triggering unit) to PowerChainGroup
and this in the Loop trigger
  • If ((PowerChainGroup is empty) Equal to True) then do (Trigger - Turn off (This trigger)) else do (Do nothing)
to turn this on/off.

Instead of many Location variables you could simply use arrayed one.
