Easing functions for Godot (v3.2.x)

Bring the powerful easing functions to godot

Usage

Copy the script in your project resource folder and call them as:

Easing.[TYPE].[FUNC](t, b, c, d)

or for Vector2 object:

EasingV2.[TYPE].[FUNC](t, b, c, d)

or for Vector3 object:

EasingV3.[TYPE].[FUNC](t, b, c, d)

inside your code.

Sorry about using different class names for each data type but GDScript does not support (at this time) Function Overloading.

example:

var t = 0

func _process(delta):
    t += delta
    position.x = Easing.Expo.EaseOut(t, 0.0, 100.0, 3.0)

this moves on the x axis an object from position 0.0 to position 100.0 in 3 seconds decreasing the speed exponentially.
