Blend spaces

Learn to blend motion with Blend2D and Blend3D.

What is Blend2D?

Blend2D is a node that blends animations with two dimensional input values. For example it moves between walking and running animations depending on the movement direction. The blend ratio is set with a Vector2 value.

agac.set("parameters/Blend2D/blend_position", Vector2(0.5, 0.0))

This way movements look more natural.

Blend3D and blend space

Blend3D blends animations with three dimensional input. It is used for more complex movements. A blend space defines the blending area and computes weights based on the input value.

var karisim = Vector3(0.5, 0.0, 0.5)

A blend space decides how animations are blended together.

Exercise Set the blend value

In a script named BlendAyari, assign the $AnimationTree node to a variable named agac in _ready. Then set the blend value with agac.set("parameters/Blend2D/blend_position", Vector2(0.5, 0.0)) and print the text "Blend degeri ayarlandi" with print.

Show example solution

extends Node

func _ready():
    var agac = $AnimationTree
    agac.set("parameters/Blend2D/blend_position", Vector2(0.5, 0.0))
    print("Blend degeri ayarlandi")

Test yourself

What does the Blend2D node do?
- It blends animations with 2D input
- It loops a single animation
- It queues animations
- It creates a state machine
Show answer

It blends animations with 2D input — Blend2D blends two or more animations proportionally according to a Vector2 input.

Write the blend property

    agac.set("parameters/Blend2D/____", Vector2(0.5, 0.0))

Show answer

    agac.set("parameters/Blend2D/blend_position", Vector2(0.5, 0.0))
