Entity|Vec2Like| (() =>Vec2Like)
Defined in: renderer/src/ScreenFollow.ts:11
What the follow tracks each frame. An Entity reads the entity’s current
worldPosition; a Vec2Like is a fixed world coord; a function is
called every frame and may compute any world coord (e.g. the midpoint
of two entities, a position along an animated path).
