Turner sounds confusing, because it’s the name of a skill in Lemmings 3D
I realise that, can we think of a better name for the state?
Since it's the only (proposed) lem state
that actually does turn around mid-action (that is, if we go ahead with it in its current implementation), Turner seems to be ideal - the lem actually does turn
before they begin Climbing.
I'm currently very much in 2 minds about this - I think it would be better to have them either turn straight away (so that Frame 0 of the animation has them facing back the way they came in-physics, regardless of what we see in the sprite) or not have them turn in-physics until they've actually begun climbing.
Turning mid-action feels like one of those "if you don't know about it, you won't be able to solve this level that's built around it" kind of mechanics which aren't much fun as a player. Having said that though, as long as it's clear from the sprite that the lemming has turned around (maybe it could be made longer, which would make the action clearer whilst providing a bigger assignment window either side of the "turn"), it could prove to be an interesting element to this behaviour.
One thing to bear in mind is that, because the lemming turns in-physics, the sprite itself has to be drawn facing in one direction first, then the other direction once the turn has happened (because turning in-physics swaps to the opposite-facing sprite); easy enough for me to manage, but others making custom sprites in the future may find this somewhat confusing.
