Detecting Auto cast spells

Does anyone know a way to detect auto cast spells??

For example, i make a ato cast fire-arrow-based spell that increase hp by 20 per hit or something. Anyone know how to do this?

if you want to detect when the unit has casted the spell you should use something like this:

I don't think that works with auto cast unless u click on the spell and then click on a unit.

in theory it must work, becuase it detects when the effect starts. Test it and tell me if it works :)

It works for all auto-cast abilities except arrow auto-cast abilities, those are considered as an attack.

For arrows you should use a generic damage system like the one Shadow wrote(can't remember where that can be found), Vex's system(found here), or my Generic Damage stuff(found in this tutorial).

With just a little thinking(conditions for the Arrows buff) you can make it do whatever you want.

Note: Arrows work flawlessly with Vex's/My methods, since an Arrow will override an Orb

I had an idea. I don't know if it works:

Use something like black arrows or something and detect when the target get the buff?

You can detect the order that turns on autocast, that way begins casting an ability would be A unit Is attacked, and starts the effect would be Unit takes damage...

Yeah....I suppose my post went unread.

Thats what I was alluding to.
