button triggered by gun shot???

[Johnny-Rico]

I wonder how do i do that thing. when u shoot the button the button moves i think its func_button. I tried to do it but it didnt work i had to walk by the button. its for mp and i know it works cause there is a map that there is a thing like that called shiniramansion or something.

Give the button a health value.
