[Spell] Active Spells

[Jay the Editor]

So, I now in creating a tower defence where most of the towers has at least one spell. The question is - how can make spells like "Chain Lightning", "Flame Strike", "Polymorph", etc. to be an active spells so that the tower will cast it whenever an enemy approaches.

Does each spell for each tower can be activated by Players ?
Or does it totally passive ?
(Triggered when enemy comes near it) ?

I mean like, you said that each Tower has a spell right ?
Does this spell is activate-able (Player activates it) ?
Or it just a dummy spell, where the spell can only be activated via enemy comes close ?

Make a trigger.

• Autocast
  • Events
    • Unit - A unit Is attacked
  • Conditions
    • (Unit-type of (Attacking unit)) Equal to Runecaster (Dwarf)
  • Actions
    • Set r = (Random percentage)
    • If (All Conditions are True) then do (Then Actions) else do (Else Actions)
      • If - Conditions
        • r Less than or equal to 40.00
      • Then - Actions
        • Unit - Order (Attacking unit) to Night Elf Druid Of The Talon - Faerie Fire (Attacked unit)
      • Else - Actions

This is a trigger I'm currently using for basic AI in a map, it causes the cast to cast a derivative of the Faerie Fire spell on attack. The "r = random percentage" part is to induce a bit of "randomness" in the AI, so it won't always cast when available.

You can take the order part out of the If/Then/Else if you want it to always cast.

NOTE: The towers need to have an attack for this method to work.

To defskull: The spell can be activated by the player but I want it to be auto-activable when enemy approaches so that the player doesn't need to do so much of work for selecting here and there to cast the skill.

To rulerofiron99: How if I got a lot of spells? I need to trigger it one by one?

• Custom Script: call IssueImmediateOrder(whichunit, "faeriefireon")

should do the trick, just call it whenever tower with auto cast ability enters a map

Yes you have to, don't be lazy ;p
Unless you have a setup trigger (I prefer Hashtable).
Then you can combine the Event altogether instead creating 1 Event per Ability.

• Custom script: call IssueImmediateOrder(whichunit, "faeriefireon")

Don't Faerie Fire by default (auto-cast enabled) targets allied units ?
The tower should be targeting enemies... ?

Ohh haha.. Thanks a lot, defskull and rulerofiron99.

Autocast spells won't work for empty player slots.

In the hashtable method, you can save the ability, unit, and the ability's order string, and then make a general trigger that checks which unit it is, to tell it which ability to use.

faerie fire is offensive, deoncrease armor and grants you vision of the targeted unit, basically tje same as wow one
