Physics Button

How can I make a button that will push down and trigger an event when a specific amount of weight is on top of it? I already have a system in place for triggering an event, but no matter what I try the buttons don't always work like they should.

When nothing is on top of the button, it should move to/stay at its original position. When something heavy enough is on top of the button, it should move down 32 pixels. When something not heavy enough is on top of the button, it should move down a realistic amount. Whenever it moves, it should move smoothly.

Are you doing this using the physics behaviour?

Here's a way to do it by simply moving the button based on a "weight" variable in the box objects. You could also set the height of it if you can't hide it behind another object like I do in this example.

I played with nimtrix's and made the button a physics object too

Nimtrix Thank you! It works now.

keepee I got an error when opening your capx.

odd...it opens fine here. Can anyone else confirm this?

anyway.. this is all I did:

I removed the -- from the file extension and it opened as it should.

Thank you, keepee! That is exactly what I was looking for.

Only problem after I implemented it into my game is that when you place heavy objects on the button, it bounces causing the doors to open and close repeatedly.

Zephlon, try increasing the buttons 'linear damping' quite a lot. All this does is slow the objects velocity over the time.
