trying to make your lifts recognize multiple blocks as floor blocks. Like, glowstone and glass for instance. I know it already recognizes glass as a floor block, but i wanted to add Glowstone.

Tried:
floorBlock: GLASS,GLOWSTONE

but this returns a null error.
What, if any, is the correct syntax to let it recognize more than one block?

It needs to be valid yaml syntax for lists:

floorBlocks:
- GLASS
- GLOWSTONE

You might be able to also write it
floorBlocks: [GLASS, GLOWSTONE]

Let me know if it doesn't work!

It works with
floorBlocks: GLASS
FloorBlocks: GLOWSTONE

i'll do it the right way now :P
