Bouncing off of enemies

[Stonecutter]

Could someone please point me to I the logic that determines how much vertical momentum a player gains upon landing on an enemy in a spinball?


Can I also find the momentum changes brought about by striking a boss or Lance-A-Bot in that location?

This logic seems to be found at p_inter.c at line 472 (then 476).
The other logic is just a few lines ahead, at line 491.

Much appreciated!
