Foot step switches

ok i was wondering becuase i never learned how to use the foot steps or switches to open gates. could some 1 tell me how to make them work. or use it in a trigger form

To use switches, just have a trigger detecting if the switch is dead, if it is, open the gate.

For footsteps, i assume you mean foot swtiches? I'm not totally sure on what you mean here. If it is indeed foot switches, you have to kill the switch when a unit enters the region on top of it and then open the gate in the same trigger.

it doesnt auto kill when walk ontop?

...no. You have to do it yourself. At least, thats what I always did. I think your units just walk over it anyways.

well i was talking about any kind of switches... and i will foubd out if they die when u walk on them...
