Limit Location Constraint 限定位置约束

对物体的限制从其中心开始计算，而骨骼则是从其根部。

值得注意的是，尽管约束限制了其视觉和渲染位置，约束对象的数据块仍然允许(默认)对象或骨骼的坐标超出最小和最大值确定的范围，其坐标可以在 变换 面板中看到。

当拖动物体，并试图超出限定边界，视觉上以及渲染时，物体仍然被限定在边界内，但在内部，其坐标仍会变化为超出限制。如果约束被移除，约束对象将跳转到其内部指定的位置。

Similarly, if its owner has an internal location that is beyond the limits, dragging it back into the limit area will appear to do nothing until the internal coordinates are back within the limit threshold (unless you enabled the Affect Transform option, see below).

为某个轴向设置相等的最小值和最大值，可以锁定约束对象在该轴向的运动… 尽管这样是可以的，但使用 变换属性 的轴向锁定功能可能更简单！

Minimum X, Y, Z

这几个复选框分别用于启用约束对象在选定 空间(Space) 的X, Y, Z轴向的坐标下限。下方的数字按钮用于控制其极限值。请注意，如果最小值高于其对应的最大值，则约束的行为就像它具有与最大值相同的值。

Maximum X, Y, Z

这几个复选框分别用于启用约束对象在选定 空间(Space) 的X, Y, Z轴向的坐标上限。下方的数字按钮用于控制其极限值。与上一个选项相同。

As pointed out before by default, even though visually constrained, the owner can still have coordinates out of bounds (as shown by the Transform panel). Well, when you enable this checkbox, this is no longer possible — the owner’s transform properties are also limited by the constraint. However, note that, the constraint does not directly modify the coordinates: you have to select its owner one way or another for this to take effect…

拥有者

This constraint allows you to choose in which space to evaluate its owner’s transform properties. See for more information.

影响

Controls the percentage of affect the constraint has on the object. See common constraint properties for more information.
