Overview

The Axie Mixer is built upon Spine Animation but with some customization for our needs. The AxieMixer will help you to create the SkeletonData which you can use with Spine and use it as normal.

Install

⚠️ The package requires Spine Runtime Library (spine-unity 3.8 2021-11-10). You need to download it manualy, and put it on Plugins folder.

Usage

Initialize Axie Mixer

To initialize the Axie Mixer, you need to call Mixer.Init() only once at the start of the game. The best place for this method is in the loading scene.

Calling Mixer.Init() multiple times will do nothing.

Create Axie Spine

To create an axie spine, you will need to know the Axie Id and its Genes

Then create an object in scene with SkeletonAnimation component

var skeletonAnimation = GetComponent<SkeletonAnimation>();
Mixer.SpawnSkeletonAnimation(skeletonAnimation, axieId, genesStrting);

API

Mixer.SpawnSkeletonAnimation(
    SkeletonAnimation skeletonAnimation, 
    string axieId, 
    string genesStr
)

  • skeletonAnimation: Main spine component for rendering and controling animation

  • axieId: Axie id

  • genesString: Axie genes, must be gene 512

Tips

You might need to scale down the SkeletonAnimation to the desired size.

To flip the Axie, please use the scaleX field of the skeleton. Example: skeletonAnimation.skeleton.ScaleX = -1

Create Axie Spine For UICanvas

Creating Axie Spine for UICanvas is quite the same as above, the different is you will need to use SkeletonGraphic instead of SkeletonAnimation

Mixer.SpawnSkeletonAnimation(
    SkeletonGraphic skeletonGraphic, 
    string axieId, 
    string genesStr
)

Playing Animation

You can get all available animation names using this snippet.

List<string> animationList = Mixer.Builder.axieMixerMaterials.GetMixerStuff(AxieFormType.Normal).GetAnimatioNames();

Playing animation.

skeletonAnimation.state.SetAnimation(0, "action/idle/normal", true);
// The above code will play Idle animation with looping 

// For Skeleton Graphic
skeletonGraphic.AnimationState.SetAnimation(0, "action/idle/normal", true);

// You can find more information about the function here http://en.esotericsoftware.com/spine-applying-animations

Building Project

You need add AxieMixerShaderVariants into Preloaded Shaders (Project Settings/Graphics/Shader Loading)

Scene demo

In the asset, there are 2 demos that you can explore. You can find these scenes:

  • DemoMixer: or so called PlayGround.

  • FlappyAxie: This is a minigame based on FlappyBird. In this demo, you can find the AxieFigure class which helps to setup SkeletonAnimation automatically. (The axie id and genes are static though)
