FollowTarget
FollowTarget =
Entity|Transform|Vec2Like| (() =>Vec2Like)
Defined in: renderer/src/FollowTarget.ts:12
What a follow tracks each frame, always in world coordinates. An Entity
or a Transform reads the current worldPosition, so a target parented
under a moving platform tracks where it actually is on screen; a Vec2Like
is a fixed world coord; a function is called every frame and may compute
any world coord (the midpoint of two entities, a position along a path).
