Quote: "A .byc file in GameGuru is a compiled binary file containing scripts that have been transformed from their original human-readable format (such as .lua) into an optimized binary format for improved performance within the GameGuru engine."
No it isn't.
It is a file containing values that are read by a Lua script to define state engine changes and such like which can then edited by the daft visual behaviour editor doodah.
The Lua script is called masterinterpreter.lua and can be found in the files/scriptbank folder.
All Lua scripts are in plain text format until you make standalone, at which point they are pre-compiled into the byte-code format for security purposes (i.e. so they can't be edited by buyers of the game). Byte-code format does load a tad quicker so gives a small performance improvement over loading the text versions but that is a secondary consideration.
btw, I was to one who added the pre-compiling to the engine way back in the Classic days!
Been there, done that, got all the T-Shirts!
