你的问题不是很明确，但我想你想：

1. 按下鼠标按钮时启动动画
2. 释放鼠标按钮时停止动画

您可以使用Event Trigger来执行此操作。以下是在代码中执行此操作的示例：

// Drag & Drop the button into the inspector
public Button button ;

// Drag & Drop your animator into the inspector
public Animator animator ;

void Start( )
{
    EventTrigger eventTrigger = button.AddComponent<EventTrigger>( );

    // Detect when mouse button is pressed down
    EventTrigger.Entry pointerDownEntry = new EventTrigger.Entry( );
    pointerDownEntry.eventID = EventTriggerType.PointerDown;
    pointerDownEntry.callback.AddListener( ( data ) => { OnPointerDown( (PointerEventData)data ); } );
    eventTrigger.triggers.Add( pointerDownEntry );

    // Detect when mouse button is released
    EventTrigger.Entry pointerUpEntry = new EventTrigger.Entry( );
    pointerUpEntry.eventID = EventTriggerType.PointerDown;
    pointerUpEntry.callback.AddListener( ( data ) => { OnPointerUp( (PointerEventData)data ); } );
    eventTrigger.triggers.Add( pointerUpEntry );
}

public void OnPointerDown( PointerEventData data )
{
    Debug.Log( "OnPointerDown called." );

    // Stop your animation, supposing you have a bool parameter in your animator
    animator.SetBool("boolName", true);
}

public void OnPointerUp( PointerEventData data )
{
    Debug.Log( "OnPointerUp called." );

    // Stop your animation, supposing you have a bool parameter in your animator
    animator.SetBool("boolName", false);
}
