So, I am trying to make a simulation game, but I am having problems with some bugs that I can't figure out. Anyone care to check it out?

Raw code: pastebin

Are you getting an error?

[Ziriee]

Yes.

bios:155: bad argument: string expected, got nil

After a quick read-thru, I noticed a potential issue: "activecat" and "elen" used on lines 69 & 70 are never initialized.

You are correct, now it changes the background color, but crashes with the same error after that and doesn't print the thing I want it to print.

The write command on line 69 is causing the error (if you add a .."" to the end of what you pass to those write functions, then they'll fail with more useful errors).

It wants to write categoriesn[ i]["char"]. This value is set by whatever the third parameter you pass to the addCategory() function is, but when you're calling that function you're only passing two parameters: hence categoriesn[ i]["char"] is always set to nil and that write statement fails.

Thanks. A lot. it was indeed fail on my side with the addCategory()'s third parameter.

It fixed it a bit, but now it crashes on powder:77: attempt to index ? (a nil value) but when I open lua and write categories[elements[map[1][7]]][map[1][7]]["gravity"] It normally says 1 D:

I think you should put this check around the whole checkFallDown() function:

if map[y][x] > 0 then

Why do people go to all the effort of syntax highlighting manually....... use [code][/code] tags, you can type them manually or click the button in the formatting bar, it saves a lot of time over manually highlighting everything!

I copied it right out of his pastebin, apparently formatting and all!

See the little rubber on the top line, second from the left, that removes all formatting on the selected text.

Great! Now it works how it's supposed to! Hooray!
