Characters stand on slopes they should slide off, or cannot jump on gentle ones

Slopes confuse ground detection: a steep hill counts as floor, a ceiling counts as floor, and a gentle ramp blocks jumping. The answer lies in which way the surface faces, not in angles you have to measure. Here are the cut-offs and the slide direction.

Why this works

A surface is a floor, a slide or a wall depending on which way it faces, not on how a designer pictured it. Asking which way it faces gives a clean answer that never breaks on a straight-up wall, and a small margin stops it flickering.

When not to use it

Skip it in a game with flat floors only, or where slopes are decoration the hero walks over. And skip the sliding in games where steep ground should be a plain wall, such as a cave maze; there, a hard block is clearer than a slide.
