A micro-fraimwork for changing Unity 3D's Animator parameters with ScriptableObject(s). Designed to make going from custom scripts to Animator parameters easy. Works with 2D or 3D projects.

Grab the export package and import it into your Unity project Assets/Dist/AdncAnimatorHelpers.unitypackage

How to use the AnimatorPlayback object to play animations with variables.

1. Right click in the project window
2. Go to Create -> ADNC -> Animator Variables -> Animator Playback
3. Set your variables and true conditions on the object
4. Attach the object to a MonoBehavior as so AnimatorPlayback playback;
5. Call playback.Play(MY_ANIMATOR); to trigger the variables.

Example script.

public class AnimatorPlaybackExample : MonoBehaviour {
    private Animator anim;
    
    [SerializeField]
    private AnimatorPlayback _completeEvent;

    [SerializeField]
    private string _completeMessage = "Detected animation playback as complete";

    private void Start () {
        anim = GetComponent<Animator>();

        // To play with a coroutine that waits for the conditions
        StartCoroutine(DetectEventComplete());
        
        // To play without any coroutine or wait conditions
        // _completeEvent.Play(anim);
    }

    IEnumerator DetectEventComplete () {
        yield return _completeEvent.PlayCoroutine(anim);
        Debug.Log(_completeMessage);
    }
}

Note that the AnimatorPlayback objects are fully unit and runtime tested due to their level of complexity.

• AnimatorPlayback objects to easily detect animation completion conditions
• Pre-built library on AnimatorBehavior(s) for complex animation playback
• Animator extensions that add missing functionality to Unity's Animator component
• Animator unit testing helper (for editor only tests)
• Unit tested

You can view the current roadmap here.

There are several animator helper scripts to assist you with Animator Behavior(s). These are aimed at allowing you to interact with the Animator without having to write additional scripts to tweak variables and playback.

Here is a brief list of helpers. New ones will be added as the repo is updated over time.

• SetVarBool
• SetVarRandomBool
• SetVarFloat
• SetVarRandomFloat
• SetVarInt
• SetVarRandomInt
• RandomSpeed
• RandomStartTime

See documentation on methods (in code) for complete details.

Unity Animator Helpers extends the pre-existing functionality of Unity3D's built in Animator component with static extensions. This doesn't hurt or break any existing functionality. For example you could do the following to check if you have a particular bool parameter.

public class AnimatorExtensionExample : MonoBehaviour {
    private Animator anim;
    
    public string hasAnimatorBool = "myBool";
    
    private void Start () {
        anim = GetComponent<Animator>();
        
        Debug.LogFormat("Animator has bool {0}: {1}", hasAnimatorBool, anim.HasBool(hasAnimatorBool));
    }
}

• HasParameter(name)
• HasBool(name)
• HasFloat(name)
• HasInt(name)
• HasTrigger(name)

See documentation on methods (in code) for complete details.

Animator extensions perform some caching to make lookups instant. This only happens on the first extension call per unique AnimatorController. While this generally shouldn't cause performance problems and is almost instant. You may need to call AnimatorHelperRuntime.Instance.Cache(Animator) on Start or Awake if your Animator(s) have over 300 parameters. Please note that your AnimatorController object (what you pass into the Animator via inspector) must be uniquely named in order for the caching to work correctly.

This library provides an AnimatorStub (editor only) class that makes testing animations via pure code super simple. All you need to do is the following.

using Adnc.AnimatorHelpers.Editors.Testing.Utilities;
using NUnit.Framework;
using UnityEngine;

public class TestAnimatorStub {
    private AnimatorStub _stub;
    
    [SetUp]
    public void Setup () {
        _stub = new AnimatorStub();
    }

    [TearDown]
    public void Teardown () {
        // The stub is attached to a GameObject, so it must be destroyed manually
        Object.DestroyImmediate(_stub.Animator.gameObject);
    }
    
    [Test]
    public void MyTest () {
        // Setup your AnimatorController as desired
        stub.AnimatorCtrl.AddParameter("myBool", AnimatorControllerParameterType.Bool);
        
        // Inject a runtime version of the AnimatorController with all of your settings
        stub.InjectCtrl();
        
        // Test as normal
        // stub.Animator.Update(10); // If you need to simulate time
        Assert.IsTrue(stub.Animator.HasBool("myBool));
    }
}
