main function has more than 200 local variables

Hi there,

I’m going crazy here (haha) with the error that I’m getting:

3159: main function has more than 200 local variables

I really need more then 200 variables! How can I do it? [import]uid: 8556 topic_id: 5787 reply_id: 305787[/import]

Ricardo,

I don’t know how to solve this problem (if there’s even a workaround), but I’m curious, are you placing 200+ local variables in one function? Or 200+ in your entire program? I would be shocked if we’re limited to 200 local variables in an entire game… I haven’t counted the variables in my current game, but it’s very likely over that amount, considering all local variables and local functions together!

Hopefully there’s a workaround for this… first time I’ve heard about this error. Perhaps it’s a Lua limitation more than a Corona limitation? 200+ within a single function seems rather heavy IMHO, but I’m sure you have a very specific reason why it must be so. :slight_smile:

The error message is not exactly what it looks like. The problem is that functions are considered variables too. I have A LOT of functions at my game.lua file and now I’m working to put it all in different files, but it’s a hard work! [import]uid: 8556 topic_id: 5787 reply_id: 20122[/import]

a workaround is to place the variables in a table

do you have code i can look at

#6

My game.lua file have 3000+ lines. I’m separating some functions into different files.

If I still have problems, I’ll talk to you, Carlos.

Thanks!! [import]uid: 8556 topic_id: 5787 reply_id: 20253[/import]

I had this same problem. The limit seems to be 200 local variables per one single function, and yes you are right, functions count as variables.

I found that consolidating variables into tables works really well if separating becomes too much of a hassle.

Good Luck! [import]uid: 9187 topic_id: 5787 reply_id: 20303[/import]

Ricardo,

you can put as many functions as you like in a table: local function add(a,b) return a+b end local function sub(a,b) return a-b end are 2 local variables, but

local f={["add"]=function(a,b) return a+b end,["sub"]=function(a,b) return a-b end} is just 1

I kept getting too many, 200 etc and found this solution but took a long time to get the functions to work.
You have to call the functions by putting the table name first then a dot.

The table above is called f, therefore to call the function [“add”] from within this table, call:

f.add ((((((not just add)))))) Think - Use a table like you would an external module.

Hope this saves someone some time. [import]uid: 47300 topic_id: 5787 reply_id: 38629[/import]

I’ve just run into this problem as well. Is combining functions into a table the best way around this limit? [import]uid: 1560 topic_id: 5787 reply_id: 96311[/import]

@Dotnaught please see this thread:

Tables are your solution.
