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 using Godot; and using tweens.gd;, 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:

CurveMotion.cs

public partial class CurveMotion : Sprite2D
{
    [Export] public Curve MotionCurve { get; set; } = new();

    public override void _Ready()
    {
        var move = new Tweens.Position2DX(300, 0.6) { Curve = MotionCurve };
        this.Tween(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 EaseFunction, not both. Either overrides the built-in ease. Custom profiles keep their own pacing instead of using the In/Out split controls.
