[ARX]求助 块的制作出现问题
<P>以下是我的程序：程序实现（1）makeablock制作一个块 块包含的实体自己选定（2）printall 显示刚才制作的块的一些特性</P><P>问题：为什么特性不能显示？</P>

<P> acutPrintf("\n");<BR>}</P> 是不是应该把const char *pCname = pEntity->isA()->name();的const去掉?<BR> <P>不是 因为 for (pBlockIterator->start(); !pBlockIterator->done(); pBlockIterator->step())这个循环进不去，块浏览器根本没有发现实体<BR></P>
