Re: Tolua and indexed array pointers

["R. Frazier" <rtdoger@...>]

I got it working!  Just tell me if this is an acceptable way to do it.

I had to trick Tolua :) to think that I was using an indexed array instead
of a pointer, so in my package file, I did this:

extern int num_vectors;
extern vec3 vectors[1];

Then after I tolua created the binding, I changed the header file back to:

extern int num_vectors;
extern vec3 *vectors;

And in the binding code, I removed all array range checking code:

#ifndef TOLUA_RELEASE
if (tolua_index<0 || tolua_index>=1)
tolua_error(tolua_S,"array indexing out of range.",NULL);
#endif


My Lua test script now works.  Does this hack sound acceptable?
