Copy Location Constraint 复制位置约束

Important

请注意，如果对 相连 骨骼使用该约束，将不起作用，因为父级骨骼头部位置决定了该骨骼根部所在位置。

复制位置面板。

Target 目标

used to select the constraints target, and is not functional (red state) when it has none. See common constraint properties for more information.

这些复选框用于选择被约束轴向。

反转

Invert their respective corresponding axis coordinates.

偏移量

启用后，允许约束对象(使用其当前的变换属性)相对于目标位置产生偏移。

Target/Owner

影响

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

示例

Let us animate a solar system with the Copy Location constraint and its Offset option. You can make the owner, called “moon”, describe perfect circles centered on the world origin (using e.g. Location X/Y sine and cosine F-Curves, see 内建函数修改器). Then copy the location of a target “earth” with the Offset checkbox enabled to model a satellite in a (simplified) orbit around its planet. Repeat these steps for more planets circling around its center star “sun”.

Following video is a small animation of a solar system created using (among a few others) the previously described technique:

Note that, this ‘solar’ system is not realistic at all (the wrong scale, the earth is rotating in the wrong direction around the sun, …).
