Making a trigger recognise a certain unit

[evans d [16aa] 12]

Ok, I want a trigger to ONLY recognise my chopper rather than any units on the ground that may pass through it or any other air units that might pass through it. How would I do that?

Thanks!

Group the trigger with the chopper.

Sycronize, not group!

Oh, I thought it'd be harder than that...

My mistake! :D

Thanks guys!

Nope, group (F2) :)
