Btw Radamantus don't double post.
This would make it MUI
[trigger=Jump]
Events
Unit - A unit Starts the effect of an ability
Conditions
(Ability being cast) Equal to Jump
Actions
Unit - Add Fly Trick to (Triggering unit)
Unit - Remove Fly Trick from (Triggering unit)
Unit - Turn collision for (Triggering unit) Off
Unit - Order (Triggering unit) to Move To (Target point of ability being cast)
Animation - Change (Triggering unit) flying height to 500.00 at 500.00
Wait 0.90 seconds
Animation - Change (Triggering unit) flying height to 0.00 at 1500.00
Wait 0.90 seconds
Unit - Turn collision for (Triggering unit) On
[/trigger]
Indexing is better then hashtables still, some disagree that they're "much" better.
As well waits do not make it Non-MUI, make sure you know when your trying to help that you know what your talking about, but yeah this will be rejected for being too simple.
Also your leaking a point, Target Point of ability being cast is the one leaking, and why don't you use crow form and remove it at same time? It is much easier and works for all units, or are you just trying to use demon hunters animation?
