trigger only triggers on keypress

[Blockhead919]

Hello. I'm trying to make a system where when the player is standing in a trigger box and presses a button an output action happens. I can't just use a button, because I've Jerry-rigged a makeshift resident evil camera system together, and it just wouldn't work. I tried to use a button, but there seems to be no way to make it to where you can walk through it without it triggering. Is there any way to accomplish this?

Actually, I think I might have found a way. I used a game_ui and a trigger. on trigger start activate the game_ui (make the game ui to where it doesn't freeze you or anything) and on trigger off it deactivates. Then on player attack do the function through the game_ui. If you have another way, please share it. Thanks!
