Need help on how to make a botton be pushed when a part is on it

Hey! I want to make an obby type game where you can pick up items to help you climb up inspired by the half life pickup system as well as portals

(i couldn’t send the file for some reason but i think sending it from yt is fine)

I am running into issues with it I’ve been trying to make it work kind of decent for a bit but never really achieved my goal it always broke

You could try using a prismatic constraint and a spring, which has worked for me in the past. The prismatic constraint locks the button on an axis while still having physics, and the spring holds it in place until something heavy enough is on it.
