Customizing Platform Movement for Steep Slopes

I can't figure out how to stop my platforming character from hopping up a steep slope. I've tried bounding box and per pixel and neither helps. I want him to jump on the slope then slide down.

My suggestions for jumping

Disable jumping when on the slope

Or

Give character horizontal momentum when jumping off a slope; enough to subvert their ability to jump up hill.

Haven't experimented with it much

But I think the new "additional velocity" command for platform behavior might be able to help you out on the sliding.

Having a slope object would be messy, but if there's no other way to do it that's fine.
