Some problems about the decompiled LUA codes

I decompiled some of the LUA files of Mafia2.




But I couldn't understand them.


 




For example :


 




I noticed that each LUA file has these two functions:


 

function
onGameInit(_ARG_0_
)




xxxxxxx




end



 




function
onEvent(_ARG_0_
,
_ARG_1_
)




xxxxxxx




end
