Slide waypoint markers along a compass bar and keep them right at north

A strip compass with markers for your camp and the nearest cave is simple until you turn across north, when markers fly across the whole strip or vanish. Here is how to place them, fade them at the edges and pin the important ones.

Why this works

Directions live on a circle, where 350 and 10 are close neighbours. Measuring each marker as a small turn left or right of where you face, instead of as a raw number, keeps them still and sensible when you pass north.

When not to use it

Skip it when the world has no fixed north or the player cannot turn freely, such as a side-scroller or a top-down map. Show distance and direction with a flat arrow or a map pin instead.
