Question

如何检测触摸屏上的长按然后激活动画？手指松开后，顺利播放另一个动画？让我们以Crossy Road中的主角为例：当用户按下时，鸡“蹲下”，当用户松开手指时，鸡会跳起来。同样的概念。 C＃。

Answer 1

bool state;
bool calledLong;
float timer;
float timeForLongPress = 1;

void Update () {
    if (Input.GetMouseButtonDown (0)) {
        state = true;
        //Write here method you want to call instantly when user presses the button
    }
    if (state) {
        //Write here method you want to call whenever user is holding mouse button
        timer += Time.deltaTime;
        if (timer > timeForLongPress) {
            //Write here method you want to call EACH FRAME after user is holding mouse button for more than "timeForLongPress"
            if (!calledLong) {
                calledLong = true;
                //Write here method you want to call only ONCE after user is holding mouse button for more than "timeForLongPress"
            }
        }
    }
    if (Input.GetMouseButtonUp (0)) {
        timer = 0;
        calledLong = false;
        state = false;
    }
}

输入.GetMouseButtonUp（0），输入.GetMouseButtonDown（0）这是左键单击，右键单击只需将0更改为1，中间单击更改0到2。

如果您想要触摸（移动），只需更改

“Input.GetMouseButtonDown（0）”to“Input.touchCount＆gt; 0”

并更改

“Input.GetMouseButtonUp（0）”to“Input.touchCount == 0”

就是这样。

您可以通过多种方式执行此操作，但您可以轻松尝试

Coroutine longPressCoroutine = null;
bool longPress = false;
void Update () {

    if (Input.touchCount > 0 && Input.GetTouch(0).phase == TouchPhase.Began)
    {
        longPressCoroutine = StartCoroutine(PlayerAnimationAfterTime());
    }
    else if(Input.GetTouch(0).phase == TouchPhase.Ended)
    {
        if(longPressCoroutine != null)
        {
            StopCoroutine(longPressCoroutine);
            // if you want to play second animation only in case of longpress then use this 
            //check otherwise just play your animation here;
            if(longPress)
            {
                //play your second animation here
            }
            longPress = false;
        }
    }
}

IEnumerator PlayerAnimationAfterTime()
{
    yield return new WaitForSeconds(2f);
    //Play your first animation here;
    longPress = true;
}

Answer 3

如果您不知道如何顺利更改动画，则需要查看Mecanim教程。这很简单。只是从第一个动画转换到第二个动画。并在检查员处设置此过渡的平滑度。

然后通过脚本触发第一个动画时按下。如果长按，则在释放时触发第二个。
