[Solved] Detecting player casting ability from neutral building.

[Jordguitar]

How with triggers do I detect the player casting an ability from a neutral building?

Untitled Trigger 001
Events
Unit - Race Chooser 0000 <gen> Begins casting an ability
Conditions
(Ability being cast) Equal to Next page
Actions
Selection - Select Race Chooser (Page 2) 0002 <gen> for (Triggering player)

So I'm trying to create a 2nd page in a neutral building using a ability, and when that ability goes off it will take me to page 2. (A dummy unit for the shops next page.) But I can't figure out how to make the computer detect who's using it, as I want it to be able for all players to use it.

Thanks.

You could have it sell units instead of using abilities, then you detect owner of sold unit.

The other way would be to make a race chooser unit for each player.

Thanks, this works, can't believe I didn't think of this myself.
This is solved.
