JavaScript => var armStretch: float;
C# => float armStretch;

Description 描述

Amount by which the arm's length is allowed to stretch when using IK.

当使用IK手臂允许的拉伸量。

Inverse Kinematics (IK) can often be handled more smoothly if a small amount of “slack” is allowed in the positions of bones relative to each other. This property controls how much slack is available in the arm joints.

如果相对于其他的骨骼位置允许小幅的“松弛”，反向运动学（IK）通常能处理的更多的平滑。该属性控制激活的手臂关节“松弛”多少。

The value is given in world distance units in the range 0..1. For example, with the default setting of 0.05, the arm will begin to stretch when the IK goal is at 95% of the target and will stretch by 5%. The stretch is carried out by translating both the elbow and wrist transforms.

该值是世界坐标距离，范围在0~1之间。例如，默认设置为0.05，表示当IK goal是在目标的95%手臂将开始拉伸5%。拉伸是通过肘部和手腕之间的变换来执行的。

The ideal value will depend on the rig and the animation but in general, a larger value will make for a smoother IK computation at the expense of more unrealistic stretching of the arm.

理想的值将依赖于绑定和动画。但通常，较大的值会是更平滑的IK计算，但付出更不真实的手臂拉伸代价。
