Platform behavior bounce

Problem Description

This also happens in C3

When a sprite (with platform behavior) is pushed by a solid object (with sine), the sprite bounces on the ground inexplicably.

Description of Capx

There is a sprite (with platform behavior and with black color) and a solid object with sine behavior.

There is a solid tilemap type floor.

The platform behavior has the default values.

Steps to Reproduce Bug

• Step 1 - Take the sprite to be pushed by the solid object with sine behavior
• Step 2 - Let the solid object push the sprite and do not move the sprite while the solid object pushes it
• Step 3 - Observe how the sprite bounces on the floor when pushed

Observed Result

When the sprite is pushed by the solid object, the sprite bounces on the ground.

Expected Result

The sprite should not bounce on the ground when it is pushed.

This is a really difficult problem to solve. You're essentially wedging a solid object inside a movement object, which causes the behavior to think it's stuck inside a solid and look for a way out. I'm not sure there's a good way we can solve this in general. It's a similar problem to dropping a solid down on top of the object. It's supposed to never be inside a solid, but you placed one overlapping it anyway, with no clear way to escape it. What should it do?

The behavior could check:

Am I on the ground?

    Can I escape horizontally?

       - Yes, then I look for horizontal output and I only move on X axis

       towards the area free of objects.

If you are on the ground you should check if you can escape on the X axis only.

He currently seems to want to escape in X and Y.

This is just an idea.

Thanks but that does not help me, I think the platform behavior must respond correctly to the solids, because that's what they are for.

And that must be its function.

The platform behavior should have a perfect integration with the solids.

That is what I think.

OK, the next release first tries a push on the horizontal axis, and only does the existing behavior if that fails. That seems to help with this example, so hopefully it's fixed for the next release.

I've tried it on C3, it seems to work fine.
