不知道哪里错了

检查 一下UF_CSYS_ask_matrix_of_object(objects[0],[$matrix)] 得到的matrix是不是NULL_TAG

作者: ljbest    时间: 2005-8-18 22:26
因为你这个对象没有matrix

点了一个block实体也不行吗

好好的研究一下文档啊。文档里说的很清楚，有些对象是永远都没有Matrix的，有些对象你并没有将矩阵与它相连接，这些对象，你调用这个函数只能得到NULL_TAG；
  
Gets the matrix identifier attached to an object. An object does not
necessarily have an matrix attached to it, and some objects can never have
a matrix attached. This routine will return a NULL_TAG for the matrix
identifier if the object does not have a matrix attached to it, even if the
object can never have a matrix attached to it.
