i cant figure out how to do it. in outputs i can only kill it, i cant just disable it temporarily (it is a func_illusionary)

The easiest way would be to
1. make a playerclip and the shield brush.
2. Tie the shield brush to a 'func_door' and make it move really fast.
3. Make the playerclip disable when you can get through.

Sorry if this isn't very clear, its late and I'm tired.

Make an Alpha input for the func_illusionary. 0 is invisible and 255 is visible.

thx for the help!

i tried the alpha set to o and it doesnt seem to work, i can still see the gate when i trigger it

ok, i figured it out
