Cube on platform (Help!)

Good afternoon guys, okay? Well, I'm new to Unity 3D and I need help in building a algaritmo for a code. I'm wondering on how to make a code in C # that checks whether an object (a cube) is on a platform. Like in some games where the player must push a box up a button so that it is pressed ... Does anyone have any idea? Thank you so much!

 

Easiest way I can think of is to set a collider (marked as a trigger) on the platform. Then you can either do something in the OnTriggerStay and related methods, or in your code, directly test whether it's on the platform by calling something like Physics.CheckSphere.

I understand, thanks! But my idea is to put a quick animation on the platform, lowering and raising it if you have something on top or not. So I put this animation within the OnTriggerStay?

 

Yes, that should work.

 

I'm getting to do, but it has a problem ... I've never used OnTriggerStay, and thought he would be fired just as the box was above the platform. However this does not occur. Once it is activated, it disappears and does not return ... Will some other way to leave it turned on only while with the box on top?
