Unity中的点击，长按，划动

public void GetClickType()
{
	if(Input.GetMouseButtonDown(0))
	{
		if(isGetBeginPos)
		{
			beginPosition = Input.mousePosition;
			isGetBeginPos = false;
		}
		if(isCheckCollider)
		{
			//检测碰撞体

			isCheckCollider = false;
		}
	}

	if(Input.GetMouseButton(0))
	{
		timer += Time.deltaTime;
		curPosition = Input.mousePosition;
		if(Mathf.Abs(curPosition.x - beginPosition.x)<0.05f && Mathf.Abs(curPosition.y - beginPosition.y<0.05f)
			&& curPosition.z - beginPosition.z<0.05f)
		{
			//以1S为点击和长按的判定条件
			if(timer > 1)
			{
				isLongPress = true;
			}
			else
			{
				isSingleClick = true;
			}
		}
		else
		{
			isPadding = true;
		}
	}
	if(Input.GetMouseButtonUp(0))
	{
		if(isSingleClick){
			clickType = ClickType.SingleType;
			isSingleClick=false;
		}else if(isLongPress)
		{
			clickType = ClickType.LongPress;
			isLongPress = false;
		}else if(isPadding)
		{
			clickType = ClickType.Padding;
			isPadding = false;
		}
	}
}

　　总体来说是用布尔值和时间来控制的，多久时间算长按是根据具体需求走的
