Author: "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: exter

2008/7/27 E. Wing <ewmailing@gmail.com>: It is possible. In my_matrix[2][1] there are two metamethod calls. One on the matrix itself, and one on an intermediate object. To have this work, you need to

There are four points where Lua has one-based table indexes: (1) In the implementation, which is invisible apart from the performance effects. LuaJIT uses a zero base for the array part of its tables

Hello, Yes I am sorry, I forgot the "k". Here is the right code : -- iterator = 0 basic_table ={k={},v={}} str for x = 0,5 do iterator = iterator + 1 basic_table["k"][iterator] = iterator + 100 end s

Aside: If you use this scheme, use numeric for instead of ipairs(). Not only will ipairs() miss the 0 index, but numeric for is faster anyway (which is clearly important to you). /s/ Adam
