等待动画在unity3d完成 [英] Wait for an animation to finish in unity3d

问题描述

我有在更新 -function扮演，在切换动画情况。

I have an animation which plays in the Update-function, in a Switch case.

在动画完成后，一个布尔值被设置为true。

After the animation finishes, a Boolean is being set to true.

我的code：

case "play":    
    animation.Play("play");     
    gobool = true;
    startbool = false;
    break;

问题是我的 gobool 和 startbool 立即得到设定没有完成的动画。我怎样才能让我的程序等待，直到动画完成？

The problem is my gobool and startbool get set immediately without finishing the animation. How can I let my program wait untill the animation is finished?

推荐答案

基本上你需要做两件事情对这个解决方案的工作：

Basically you need to do two things for this solution to work:

1. 开始动画。


2. 等待动画播放下一个动画之前完成。

怎么可以这样做的一个例子是：

An example of how this could be done is:

animation.PlayQueued("Something");
yield WaitForAnimation(animation);

和定义为 WaitForAnimation 是：

C＃：

private IEnumerator WaitForAnimation (Animation animation)
{
    do
    {
        yield return null;
    } while (animation.isPlaying);
}

JS：

function WaitForAnimation (Animation animation)
{
    yield; while ( animation.isPlaying ) yield;
}

在do-whil​​e循环来自该实验的结果表明， animation.isPlaying 收益假在同一帧PlayQueued被调用。

The do-while loop came from experiments that showed that the animation.isPlaying returns false in the same frame PlayQueued is called.

通过稍微修改一下就可以创建一个动画扩展方法，简化了这个功能，比如：

With a little tinkering you can create a extension method for animation that simplifies this such as:

public static class AnimationExtensions
{
    public static IEnumerator WhilePlaying( this Animation animation )
    {
        do
        {
            yield return null;
        } while ( animation.isPlaying );
    }

    public static IEnumerator WhilePlaying( this Animation animation,
    string animationName )
    {
        animation.PlayQueued(animationName);
        yield return animation.WhilePlaying();
    }
}

最后，你可以很容易地在code使用：

Finally you can easily use this in code:

IEnumerator Start()
{
    yield return animation.WhilePlaying("Something");
}
