[NPC Pack] Polflip

[Emral]

Flip! Flop! He will never stop!
He tries to move in one direction until he figures out it's impossible. A direction change happens after 2 unsuccessful flips. They can phase through rightside-up slopes from below. Thanks Redigit!

If you set them to "Don't Move", they operate on a timer instead.

Appears to be incompatible with custom blocks (IDs 751-1000) and will flip immediately if it's standing on one or walks onto one. Other than that it works right.

You have to register your block to the expandeddefines block lists. Polflip can't know what the collision is like from the sprite alone!

I don't know how to do that. Is it in the Polflip files or somewhere else?

Expandeddefines...
expandedDefines.registerBlock(id, typeList)
Typelist is something like expandedDefines.BLOCK_SOLID or expandedDefines.BLOCK_SEMISOLID (I think Block.SOLID and Block.SEMISOLID work too but I'm not sure).
A list of typelists can be found in expandedDefines.lua

So I guess I add {751, 752, 753, 756, 757, 812, 822, 832, 842} (Not sure how it would work with the Exclusive Blocks states) to expandedDefines.BLOCK_SOLID then? I assume I just do that in the luna.lua somehow?
