How do I make a moving platform?

I'm kind of embarrasses to ask this but I've run forum and tutorial searches and can't find anything that points me in the right direction as to where to start it terms of behaviors or events that give me horizontal and vertical moving platforms. For a platforming game.

Really simple ones, that travel a set distance, then return to their start point. Then repeat.

Anyone have demo code I could just crib from?

sine behavior will do that for you, up-down or left-right or sine movement, all possible

I believe there are example of that in C2 already

Oh, is that what sine behavior is for? I'll read up on it. Thanks for pointing me in the right direction. I figured I was missing something basic.

You might want to have a look at the built-in templates and examples, which include examples with moving platforms.
