Godot CurvesGodot Curves

Draw your own easing in the Inspector as a Godot Curve when a built-in family does not fit. The tween samples it over its progress.

Examples use the global Tweens class in a node script, with targets inside the scene tree.

Use a Curve Resource

Create a Curve resource in the Inspector and shape its points over the 0–1 domain. Export a field to assign it:

curve_motion.gd

extends Sprite2D

@export var motion_curve: Curve

func _ready() -> void:
    var move := Tweens.position_2d_x(300.0, 0.6)
    move.curve = motion_curve
    Tweens.play(self, move)

Each playback gets its own curve copy, so edits affect later starts.

Time in, weight out

The x axis is progress, from 0 to 1. A height of 0 holds the start value and 1 the end value. Raise the curve’s Max Value above 1 for overshoot.

Choose one custom source

Set curve or an ease_function, not both. Either overrides the built-in ease. Custom profiles keep their own pacing instead of using the In/Out split controls.

The easing reference covers validation and failures.
