DOTween 版本 1.2.420 免费版

C# 导出的配置文件，添加 DOTween 的类

// DOTween
typeof(DG.Tweening.Sequence),
typeof(DG.Tweening.DOTween),
typeof(DG.Tweening.DOTweenModuleSprite),
typeof(DG.Tweening.DOTweenModuleUI),
typeof(DG.Tweening.ShortcutExtensions),
typeof(DG.Tweening.TweenExtensions),
typeof(DG.Tweening.TweenSettingsExtensions),
typeof(DG.Tweening.Ease),

TS 代码里添加代码

// DOTween 的扩展
(function () {
    $extension(UnityEngine.Component, DG.Tweening.ShortcutExtensions);
    $extension(UnityEngine.Transform, DG.Tweening.ShortcutExtensions);
    $extension(DG.Tweening.Tween, DG.Tweening.TweenExtensions);
    $extension(DG.Tweening.Sequence, DG.Tweening.TweenSettingsExtensions);
    $extension(UnityEngine.UI.Image, DG.Tweening.DOTweenModuleUI);
    $extension(UnityEngine.UI.Text, DG.Tweening.DOTweenModuleUI);
    $extension(UnityEngine.RectTransform, DG.Tweening.DOTweenModuleUI);
    $extension(UnityEngine.SpriteRenderer, DG.Tweening.DOTweenModuleSprite);

    let TweenerVector3 = $generic(DG.Tweening.Core.TweenerCore$3, UnityEngine.Vector3, UnityEngine.Vector3, DG.Tweening.Plugins.Options.VectorOptions);
    $extension(TweenerVector3, DG.Tweening.TweenSettingsExtensions);

    let TweenerVector2 = $generic(DG.Tweening.Core.TweenerCore$3, UnityEngine.Vector2, UnityEngine.Vector2, DG.Tweening.Plugins.Options.VectorOptions);
    $extension(TweenerVector2, DG.Tweening.TweenSettingsExtensions);

    let TweenerString = $generic(DG.Tweening.Core.TweenerCore$3, System.String, System.String, DG.Tweening.Plugins.Options.StringOptions);
    $extension(TweenerString, DG.Tweening.TweenSettingsExtensions);

    let TweenerQuaternion = $generic(DG.Tweening.Core.TweenerCore$3, UnityEngine.Quaternion, UnityEngine.Quaternion, DG.Tweening.Plugins.Options.QuaternionOptions);
    $extension(TweenerQuaternion, DG.Tweening.TweenSettingsExtensions);

    let TweenerColor = $generic(DG.Tweening.Core.TweenerCore$3, UnityEngine.Color, UnityEngine.Color, DG.Tweening.Plugins.Options.ColorOptions);
    $extension(TweenerColor, DG.Tweening.TweenSettingsExtensions);
})();

使用过程中，暂时只发现 DOScale 调用有问题，改成 DOScaleX 和 DOScaleY 后，就没问题了，原因未知
调用 DOScale 时的报错信息
