Why does my Camera2D jitter when zoom changes?

Position smoothing computes the lerp between current and target. Zoom change shifts the target position (because zoom rescales offsets). If smoothing speed and zoom speed don't align, the camera oscillates.

How do I animate zoom smoothly?

Tween the zoom property over a fixed duration: tween.tween_property($Camera2D, 'zoom', Vector2(2,2), 0.5). Disable position_smoothing during the tween if combined motion looks bad.

Should I use a CinemachineCamera-style follow system?

For complex zoom + follow behavior, write a custom Camera2D wrapper that drives both target and zoom in lock-step. Stock Camera2D smoothing is fine for simple cases.

Fix: Godot 4 Camera2D Smoothing Jitter on Zoom Change

Quick answer: Animate zoom with a Tween over 0.3–0.5s. Optionally disable position_smoothing during the tween to avoid combined motion artifacts. Use create_tween().tween_property for clean interpolation.

Player presses zoom-out. Camera jitters along the path because position smoothing fights the zoom change.

The Symptom

Camera jitters or oscillates during zoom transitions. Smooth at static zoom levels.

The Fix

extends Camera2D

func zoom_to(target: float, duration := 0.4) -> void:
    position_smoothing_enabled = false
    var tween := create_tween()
    tween.tween_property(self, "zoom", Vector2(target, target), duration)
    await tween.finished
    position_smoothing_enabled = true

Disable smoothing during the tween; re-enable after. Zoom interpolates cleanly without fighting position lerp.

Verifying

Trigger zoom changes during gameplay. Smooth, no jitter. Smoothing returns for normal follow.

“Tween zoom. Suspend smoothing. Re-enable. Smooth.”
