python-2.7 - Maya：寄养节点时查询约束信息

问题描述

在 Maya 中，当它是一个寄养节点时，有没有办法查询约束的源和目标？

我正在尝试诊断成为养父母后连接丢失的问题，因此我需要中间信息来与有效的约束进行比较。

我遇到的所有方法都需要建立连接，但是虽然它是一个寄养节点，但这些方法并不存在。Maya 能够恢复连接，因此信息必须存在于某处。

解决方案

您可以尝试通过参考的编辑来识别约束。打开参考编辑器，然后运行 ​​File->List reference edits。这将弹出一个新窗口，其中将显示在参考之外进行的所有编辑。此列表可能很大，因此您可以输入约束的名称来过滤结果。

现在，如果您尝试通过脚本访问它，您可以使用cmds.referenceQuery.

将参考节点而不是养父母传递给这些命令：

edit_strings = cmds.referenceQuery("YOUR-REF-NODE", editStrings=True)
edit_nodes = cmds.referenceQuery("YOUR-REF-NODE", editNodes=True)
edit_attrs = cmds.referenceQuery("YOUR-REF-NODE", editAttrs=True)

for line, node, attr in zip(edit_strings, edit_nodes, edit_attrs):
    print line, " ::: ", node, ":::", attr

打印出来的结果如下：
