********************************************************************************************
*
*   Chain abilities are great spells and are used by many map-makers that use Chain Lightning
*   and Healing Wave that are built into the object editor. However, that provides minimal
*   control over how the abilitiy functions in-game. With this system, you can create
*   Chain spells with just once function call (GUI-Friendly) or highly customize them through
*   struct variables. All Chains are MUI and leakess.
*
********************************************************************************************
*
*   Usage over default Chain Lightning/Healing Wave in the object editor:
*
*   - Define any lightning type you want.
*   - Apply custom stats to to almost every variable used.
*   - Trigger a custom action to targets hit by a Chain (Such as stun, slow, etc).
*   - Modify the color of the lightning.
*   - Define the Chain instance jump interval.
*   - Control on how much damage/heal is dealt.
*   - Greater ability to increase/decrease how much damage/heal per bounce is modified.

When I get back to my desktop I'll create an example of how to use it via GUI. It does not require the use of multiple custom scripts, only one! I'll also add better documentation on how to use it with GUI without the pre-made functions and possibly add some extra functions specifically designed for GUI users so they can better customize the chains. Sorry for the confusion! I'll get it updated soon.

The chainsys is mainly intended for advance usage, but I'll add more simplified ways of creating and modifying the chains.

Spell Review:

System:

  • The library GroupUtils, although declared as optional, will cause the library ChainSys to not compile correctly when not found.
    • Error type is misnaming of a destructor function, which is RemoveGroup. It should be DestroyGroup
      It is found within these methods:
      • static method onTimer()
      • method destroy()
  • In static method onTimer(), a local trigger is created and destroyed upon execution. A suggested optimization is to save that trigger instead as a private member of the struct Chain and only destroy the trigger upon invocation of destroy(), or changing of the callback function, creating a new one with the new callback.

  • The library Damage does not appear to have any impact on the system. A recommended course of action is to omit that library from the system.

GUI-Friendliness:


As it stands, the system is still quite far from being GUI-friendly, due to numerous function parameters which may confuse users.
Such are the following examples (Two of which are included, despite being preset functions):
  • public function AddLightningTimed(string effectId,unit source,unit target,real duration,real red,real green,real blue)
  • public function Chain_ChainLightning(unit caster,unit target,real damage,real damageModify,real radius,integer bounces,real intervals,boolexpr groupFilter,code whichEvent) (A preset function)
  • public function Chain_HealingWave(unit caster,unit target,real heal,real healModify,real radius,integer bounces,real intervals,boolean hitCaster,boolexpr groupFilter,code whichEvent) (A preset function)
In addition, if a GUI user wants to cast a truly custom Chain Lightning (different lightning models), the user must have to declare at least 2 lines of Custom Scripts.

In order to resolve this, a recommendation is to create a helper trigger which interfaces nicely with the system, as the system is already in place. The helper trigger will enable GUI users in creating custom Chain Lightning(s) of any sort without having to look into the function parameters above. Additionally, a customizing helper trigger would help them a lot more by directly assigning the members of a desired Chain instance to arbitrary GUI variables that you would have created by then.
