JavaScript => public var deltaTime: float;
C# => public float deltaTime;

Description 描述

Amount of time that has passed since the last recorded change in Touch values.

触摸值自上次改变已经过去的时间量。

Values for the various touch properties are updated periodically. The deltaTime value is simply the amount of time that elapsed between the previous update and the current one. This is primarily useful for determining the movement speed of the touch position with reference to deltaPosition.

各种触摸属性的值被定期更新。deltaTime值是上次update到当前的持续时间。这个主要用来确定触摸位置的移动速度，参考deltaPosition。

C#:

 public static Vector2 FixTouchDelta(Touch aT)
 {
     float dt = Time.deltaTime / aT.deltaTime;
     if (float.IsNaN(dt) || float.IsInfinity(dt))
         dt = 1.0f;
     return aT.deltaPosition * dt;
 }
