[Trigger] Ability that makes a unit invisible near trees?

[madman9800]

I know this is done in dota. Can someone tell me how i can do this in my map?

Concept:
Unit has ability "camouflage." Unit is withing "50" of a tree. Make unit invisible.
Unit leaves tree, make unit visible.

Base your spell off Invisibility by Sorceress and you just have to make triggers:

• Trigger
• Events
  • Unit - A unit starts the effect of an ability
• Conditions
  • (Ability being cast) Equal to X
• Actions
  • Unit Group - Add (Target unit of ability being cast) to InvisibilityGroup
  • Trigger - Turn on Trigger2 <gen>

• Trigger2
• Events
  • Time - Every 1.00 seconds of game-time
• Conditions
• Actions
  • If (All conditions are true) then do (Actions) else do (Actions)
    • If - Conditions
      • (InvisibilityGroup is empty) Equal to False
    • Then - Actions
      • Unit Group - Pick every unit in (InvisibilityGroup) and do (Actions)
        • Loop - Actions
          • Set Point = (Position of (Picked unit))
          • Destructible - Pick every destructible within 200.00 of Point and do (Actions)
            • Loop - Actions
              • If (All conditions are true) then do (Actions) else do (Actions)
                • If - Conditions
                  • (Picked destructible) Equal to No destructible //Destructible comparison
                • Then - Actions
                  • Unit Group - Remove (Picked unit) from InvisibilityGroup
                  • Unit - Remove Buff from (Picked unit)
                • Else - Actions
          • Custom script: call RemoveLocation (udg_Point)
    • Else - Turn off (This trigger)

Have you tested this? I am afraid that (Picked destructible) Equal to No destructible won't work, if there is no destructible it just won't be picked.

What you should do is to pick the destructibles, then check whether one of them is a tree, then cast the invisibility with 1 second duration. That way, as soon as the unit leaves forest, no trees will be picked anymore and the spell will fade within one second.
