Question

JavaScript => public var fingerId: int;
C# => public int fingerId;

Description 描述

The unique index for the touch.

用于触摸的唯一索引。

All current touches are reported in the Input.touches array or by using the Input.GetTouch function with the equivalent array index. However, the array index is not guaranteed to be the same from one frame to the next. The fingerId value, however, consistently refers to the same touch across frames. This ID value is very useful when analysing gestures and is more reliable than identifying fingers by their proximity to previous position, etc.

Input.touches数组报告当前所有的触摸或使用Input.GetTouch函数传入数组索引。然而，该数组的索引不能保证一帧到下一帧相同。fingerId值，然而，始终跨帧指向相同的触摸。该ID非常有用，当分析手势比通过它们更靠近上个位置识别手指更可靠，等。
