Travelling Up and Down Walls, Ceilings, Corners, Etc

[Steven M]

How would I go about doing this, exactly?

You see it in the videogame

where the player can spin up a straight wall from a straight floor, from a straight floor down a sheer cliff, etc. You also see it in Blaster Master when you get the final upgrade to scale sheer terrain.

Basically I'm trying to get the player to climb non-sloped terrain without having the mask or the sensors bugging out because of it. The player also needs to have total control of the mask when they're moving around, so they can stop on the edge of the side of a platform before transferring to the adjacent side. There's a 360-degree engine on the website that's almost useful for this, except that engine bugs out with straight walls and corners.
