Vertically moving platforms

I have a distinct need for vertically moving platforms.

However, when moving a platform up using bullet movement, the character jiggles and reacts as if it is periodically lifting off the platform, then falling back to it. This obviously isn't acceptable.

I did a quick search on this forum and found a topic from February that said it used to work right and needed fixed in a new version, but here we are in June and if this is the issue then it's still there. I'm not sure, though, so that's why I haven't gone running off to the bug tracker.

Any work-around?

Reproduce it in a new .cap and post it to the tracker, a dev will take a look.

I'm trying to post it to the tracker but am instead getting an error that says

[quote:3g4s7bcx] ERROR

Artifact:

And nothing else. It might be Sourceforge having some issues-- I'll try again later.

I'd guess so, yes. You are signed up, right?
