AnimeTask

Task Animation Library for Unity

---

Warning

This is also a very old library.
If you want to use a new one now, I recommend PrimeTween.

Sample

-> Example of use

Basic

Move from (-5f, 0f, 0f) to (5f, 0f, 0f) over 2 seconds.

await Easing.Create<Linear>(new Vector3(-5f, 0f, 0f), new Vector3(5f, 0f, 0f), 2f).ToLocalPosition(cube);

PlayTo

Move from the current location to a specified location.

await Easing.Create<Linear>(new Vector3(-5f, 3f, 0f), 2f).ToLocalPosition(cube);

Easing

Use InCubic of Easing to move to a specified position.

await Easing.Create<InCubic>(new Vector3(-5f, 3f, 0f), 2f).ToLocalPosition(cube);

Linear

Move at 1 per second for 2 seconds.

await Moving.Linear(1f, 2f).ToLocalPositionX(cube);

Gravity

const float xRange = 5f;
const float yRangeMin = 5f;
const float yRangeMax = 10f;
await Moving.Gravity(
          new Vector2(Random.Range(-xRange, xRange), Random.Range(yRangeMin, yRangeMax)),
          Vector2.down * 9.8f,
          5f
      ).ToLocalPosition(shape)

AnimationCurve

[SerializeField] private AnimationCurve sample12 = default;

public async UniTask Sample12()
{
    await Moving.AnimationCurve(sample12).ToLocalPositionX(cube);
}

CalcDuration

Move by calculating moving time from distance.

await Easing.Create<OutCubic>(new Vector3(5f, 0f, 0f), x => x / 2f)
    .Concat(Easing.Create<OutCubic>(new Vector3(5f, 2f, 0f), x => x / 2f))
    .Concat(Easing.Create<OutCubic>(new Vector3(-5f, 0f, 0f), x => x / 2f))
    .ToLocalPosition(cubes);

TranslateTo.Action

TranslateTo.Action enables you to use the animated values freely.

Easing.Create<Linear>(0, 100, 2f).ToAction<float>(x => Debug.Log(x))

UnscaledTime

You can create your own scheduler, so you can stop time for specific objects.
The default is to use Time.time, and you can also use UnscaledTimeScheduler, which uses Time.unscaledTime.

Easing.Create<Linear>(new Vector3(-5f, 0f, 0f), new Vector3(5f, 0f, 0f), 2f)
    .ToLocalPosition(shape, default, new UnscaledTimeScheduler());

Update Timing

If an update timing is specified in the scheduler, values can be updated at times other than Update.

public class CustomScheduler : IScheduler
{
    public float DeltaTime => Time.deltaTime;
    public PlayerLoopTiming UpdateTiming => PlayerLoopTiming.PreUpdate;
}

Cancel

var cancellationTokenSource = new CancellationTokenSource();
cancellationTokenSource.Token.Register(() => Debug.Log("Cancel"));
cancellationTokenSource.CancelAfter(500);

await Easing.Create<OutCubic>(new Vector3(5f, 0f, 0f), 2f).ToLocalPosition(cubes[0], cancellationTokenSource.Token);

Convert

Convert a float transition to a circular motion.

await Easing.Create<OutCubic>(0.0f, Mathf.PI * 2.0f, 2f)
    .Convert(x => new Vector3(Mathf.Sin(x), Mathf.Cos(x), 0.0f) * 3.0f)
    .ToLocalPosition(go);

Concat

It moves from 5f to 0f in 2 seconds, stops for 1 second, and moves to -5f in 2 seconds.

await Easing.Create<OutCubic>(5f, 0f, 2f)
    .Delay(1f)
    .Concat(Easing.Create<OutCubic>(0f, -5f, 2f))
    .ToLocalPositionX(cubes[0]);

IProgress

Supporting IProgress

await Easing.Create<Linear>(2f).ToProgress(Progress.Create<float>(x => Debug.Log(x)));

AnimationCanceller

var canceller = go.GetAnimationCanceller().Cancel();
Easing.Create<Linear>(1.0f, 0.5f).ToLocalPositionX(go, canceller.Token);

// in other class/scope
var canceller = go.GetAnimationCanceller().Cancel();
Easing.Create<Linear>(0.0f, 0.5f).ToLocalPositionX(go, canceller.Token);

Skip

• Cancel (using CancellationToken) will stop at the position at the moment of Cancel.
• Skip (using SkipToken) will move to the last position at the moment of Skip.

var skipTokenSource = new SkipTokenSource();
Easing.Create<OutCubic>(new Vector3(5f, 0f, 0f), 5f).ToLocalPosition(cubes[0], default, skipTokenSource.Token).Forget();
await UniTask.Delay(TimeSpan.FromSeconds(1));
skipTokenSource.Skip();

UniRx.Extensions

var score = new ReactiveProperty<int>(0);
score
    .SubscribeTask(async (x, cancellationToken) =>
    {
        scoreCounter.text = $"{x}";
        await Easing.Create<OutBounce>(2f, 1f, 0.5f).ToLocalScale(scoreCounter, cancellationToken);
    });

Instructions

• Import AnimeTask via Package Manager

• Import AnimeTask via UnityPackage
  • Import UniTask
  • Import UnityPackage

Way of thinking

You can pass two arguments to Play and PlayTo.
The first is the Animator and the second is the Translator, which have distinct roles.

Animator

Takes the elapsed time and returns the current value.

Translator

Reflect the value.

Requirements

• Requires Unity2020.3 or later
