core.param2: add todo reimplement notice
Ref https://discord.com/channels/1135598362821935254/1247681375935533119
---------------------------------------
Hi, a wild //orient+ appeared! While it (probably) doesn't crash, it also unfortunately doesn't work yet.
This is because facedir e.g. points towards the direction the node is pointing, and minetest.facedir_to_dir doesn't capture all the nuance of how the node is pointing, and e.g. if a node is pointing +y and you want to rotate by (0, 90, 0) [degrees], then the current implementation won't do anything.
Then I decided that this is silly and there has to be a solution. After all, screwdriver2 has a great implementation! https://content.minetest.net/packages/12Me21/screwdriver2/
....then I found this lookup table in their codebase: https://github.com/12Me21/screwdriver2/blob/master/init.lua#L75-L79
....aaaaarrrggggghhhhh //orient+ is such a pain to implement!
and my existing implementation is so neat 😢 1dd073f14b/worldeditadditions_core/utils/param2.lua
so, in other words, although I've implemented //orient+ I'm going to have to reimplement the nuts-and-bolts function that does the rotation, which may make it slightly more complicated and annoying to implement support for nodes with param2 types other than facedir.
/rant about Minetest's param2 value and rotations 😛
