i've found some good tips for optimizing Lua programs:

[admin]

This guide is for standard Lua, where as LM uses LuaJIT which already does many optimizations when running the code.

[buuuudzik]

FYes, but some of advices are very good also for JIT version E.g. using locals(also using local copy of  math.sin when using it in loop and modifying data model. Maybe this is for some advanced users intuitive but for sure for less of users. Also using simple for loop instead of in ipairs when you must optimize your script.

[admin]

There's no difference in using math.sin directly or caching it via local variable in LuaJIT. Both examples take the same amount of time to run. And there are not many scripts that need to calculate sine 1000000 times in a row

But, using local variables is a very good advice to avoid problems where some function overwrites a global variable with the same name and causes script errors.

Please create a separate thread and explain in more detail.

Thank you. This is probably the long time wanted entrance for "lua beginners"  "without programming knowledge".

Addendum 09/15/2020: This young man is also very helpful: https://www.youtube.com/watch?v=4NKMtazVNe8 He closed a few gaps which I didn't understand at the beginning of http://www.tutorialspoint.com/lua/ ...... Maybe I'll understand that one day or I give up as I did with my hanging man game on qBasic/dos 5.0 28 years ago.
