[Trigger] Triggering questions

[terradont]

Hi! I have some questions regarding triggering skills.

1. I know how to make a unit as a special effect and make it go to a special point, but i can't figure out how to make it react on when someone gets close to it. For example, elunes arrow in DotA.

2. I know how to somewhat use polar offset, but i don't get all of it. For example let's say i want to do a backstab spell like rikimarus or bristleback like bristlebacks in DotA.

3. I've made a skill for a hero that has a chain lightning-like spell. The skill is a shield which adds armor and a percent chance to release the chain lightning on the attacking unit. The problem is that i dont know how to make variables that is multi-instance-able so that he can add the shield to others and still set the level to the level of chain lightning of the caster.

4. How to trigger autocast-spells like searing arrows so that they do damage over time like burning spear of Huskar in DotA.

The reason i use DotA as example is that most people knows about them xD

I appreciate the help. (if i get any)

1. As Waldbaer nicely pointed to me thumbs_up you can add events to triggers in the middle of the game, so you can make a trigger telling that when a unit of kind "Eluna's Arrow" gets close to a unit - conditions - actions.

2. Don't know, played DotA about 2 times and that was before 3 years or so 0.0

3. To make the buff on others you can just use the Lich hero skill (called Frost Shield I think).
To make the varibales effective to all the units in the map that have it you can do it like this:

• Unknown
  • Events
    • Unit - A unit Is attacked
  • Conditions
  • Actions
    • If (((Triggering unit) has buff Lightning_Shield_Lvl_1) Equal to True) then do (Whatever_You_like_To_Do) else do (Do nothing)
    • If (((Triggering unit) has buff Lightning_Shield_Lvl_2) Equal to True) then do (Whatever_You_like_To_Do) else do (Do nothing)
• -------- And so on with all the levels of the spell --------

4. Can't you just use any "damage over time" (for example poison damage) attack in warcraft ?
In case you can't for some reason here's something that I think that will work:

• Unknown
  • Events
    • Unit - A unit Is attacked
  • Conditions
    • (Attacking unit) Equal to (The_Arrow_You_Want)
  • Actions
    • Unit - Cause (Attacking unit) to damage (Triggering unit), dealing 10.00 damage of attack type Normal and damage type Slow Poison
• -------- I never really tried this out so I don't know if it works or not --------

Hope I helped.

2) you compare your facing angle with an angle between our locations. if you're facing 45 deg (top right) and angle of line going from me towards you is 35-55 degrees, then i'm behind you. all the functions are there in trigger editor (they return real numbers)

4) no triggering needed. make nice icons and use poison arrows ability.
