Confirmed Aerial step-up brings player out of pain state

[Ezer'Arch]

If the character is standing near a small step and gets hurt, SRB2 won't play PAIN state, but either standing or walking states.

To reproduce it, stand quite near the step, in the lower sector, and let a Crawla hurts the character. Important: the character must be between the Crawla and the ledge and the Crawla moving towards the ledge. If the Crawla is walking along the step or going from a higher sector, nothing happens (as seen in 2nd image).

The current behavior:

The normal behavior:

(the same happens in XSRB2 and SRB2C)

To be more specific, it seems that you need to be standing below the step and be knocked directly into it; if I had to guess, I'd say this behavior occurs when step-up happens during pain.

You're right. Not only with enemies, any kind of hazards and projectiles can cause same behavior.
