回电没有被解雇，看不出有什么问题，我买了 5 美元的样品包，据我所知，我正确地遵循了他们的模式。我以前成功使用过这个。

因此，在下面的此类中，特定按钮已被按下或被取消选择。在这种情况下，我专门调试选定的补间，但都不能正常工作。InstantSelectionSpritesUp() 函数工作正常，它手动进入并将颜色 alpha 设置回 1。这工作正常，所以我已将其注释掉，现在正在尝试补间。补间不起作用。通过 Debug.Log 我知道 SetAsSelected() 和 FadeSelectionSpritesUp() 实际上正在被调用。虽然没有调用 UpdateIconAlpha() 和 UpdateBGAlpha，因为没有日志打印到控制台。StopTweens() 存在是因为当您在同一个 GameObject 上调用新的补间时，iTween 不会自动销毁预先存在的补间。我已经对此发表了评论，没有任何变化，所以这不是问题。它'

有什么想法吗？
