WanderCam

The Wanderer's third-person camera: a damped orbit around the body it follows, with a spring arm, a lead on movement, and a focus pose a conversation can borrow.

Put it on a camera rig's Camera.behavior. It never places a camera of its own — it poses the entity it is on.

Framing

Three rings around the follow target, each with a height above the target's origin and a radius out from its axis. verticalAxis slides the camera along the spline through them (0 at ringBottom, 1 at ringTop) and horizontalAxis orbits, so a low wide look-up and a high tight look-down are geometry you can see rather than angle limits you cannot. radiusScale zooms between minRadiusScale and maxRadiusScale.

Writing any of these re-poses the rig immediately with the damping bypassed, so edit mode shows the shot play mode will produce.

Lead

The aim point slides ahead of the body along its own travel: up to leadDistance at leadSpeed, eased over leadTau seconds. Walking opens the view in the direction being walked; standing still settles it back onto the body.

The travel is differenced off the target's position rather than read from a movement component, so this follows anything that moves.

Focus

cam.focus = { active = true,
              position = { x = 0, y = 2, z = -3 },
              lookAt   = { x = 0, y = 1.5, z = 0 },
              fov      = 36 }
cam.focus = {}   -- give the camera back

While focus.active is set the rig eases to that pose and that aim over focusTau seconds instead of orbiting, and the Camera's field of view eases to focus.fov. Look input is dropped rather than accumulated while the focus holds, so releasing does not swing the view by everything the mouse did in the meantime. Clearing it eases back to the orbit and to baseFov.

Controls

inputMap names the scheme this camera answers to — look orbits, zoom scales the rings. Point it at a world's own map to rebind either without touching this component.
