How to detect when a projectile hits a unit?

OK ENOUGH OF THIS DEAR GOD!!!

OK LISTEN HERE
THERE IS A WAY TO DO THIS,
In the Events under Units: There is a event that says
(Unit: A Unit Takes Damage)
That activates when the prjectile ACTUALY hits it. Not when its fired.....was that so hard? dear god ><
(If someone else has said this then im sorry for repeating it but i was 2 lazy to read all of them...)
