Re: Simple AI Scripting, Help Me!

["Brett Bibby" <research@...>]

Hi Joel!
My point on PS2 has nothing to do with Lua, which was the point!  We run into C compiler issues more than Lua issues on PS2 was what I was trying to say :-)  

But I was actually going to send a note to this list about the PS2 Lua anyway, so I might as well do that now :-)

A month or so ago somebody on this list mentioned that their PS2 Lua implementation worked but was speeded up by doing something or other (something with memory or alignment I think). I can't seem to find it in the archives (is there a better way to search them btw?).  Anyway, if anybody is using Lua on the PS2 can you post what changes you made to optimize it?

For the record, all we did on the PS2 was to change the Lua number definition from double to float and it compiled and ran fine.  Same with GameCube.  Any console developer advice would be appreciated on other things that would optimize Lua though.

Cheers,
Brett
ps: tell Bill Schmitt hiya for me.
