I've written this comment on one of the forks, but I'll paste it again here as a warning for people that still use CharacterMotor:
I know this is like many years old, but I had a bug in my game that I tracked all the way down to this script from a while ago. Moving platforms were not working correctly when they were rotating, so I wasted about 3 hours of time digging through it. Turns out there's like 4 lines in here that are commented out which are actually NOT commented out in the original JS script. Lines 273-276. The correct line that would make this script more equivalent to CharacterMotor.js would be:
movingPlatform.activeGlobalPoint = tr.position + (Vector3.up * ((controller.center.y - (controller.height * 0.5f)) + controller.radius));
An explanation as to why not having that line causes bugs: the global point of the moving platform is never properly set every frame, it stays at zero. I don't know the specifics but obviously it won't account for rotation if the global point of our character is assumed to be 0 -- i.e. it is assumed to be at the center of the object, which is why rotating platforms move offset to the character.
Changing that line actually also fixed an issue I was having where the character would fly in random directions on odd geometry, which could've been game-breaking.
So for anyone stumbling across this, do not use script this unless you make the line correction at 273. Or just use the one here, it has the correct line: https://wiki.unity3d.com/index.php/CharacterMotor
Dear @zephjc, currently using this on unity google cardboard sdk, my movements are not relative to the camera direction, do you have any solutions for this? im pretty new with unity tho.
