LUA: I want some help, please? Two things.

I feel like I'm being completely ignored D: :tinfoil:

[QUOTE=luavirusfree;39335855]Lol, damn. I guess I'm missing an '=' here?

Also, what tag do you put errors in to make them look like that one comment on this thread?

Of course, my comments make no sense since it doesn't work...[/QUOTE]

And also, how do I make a prop_combine_ball that doesn't just go through every world surface? (with the owner of the swep as the owner of the combine's ball)?

Shouldn't you be posting this in the [URL=http://www.facepunch.com/forumdisplay.php?f=65]Lua section[/URL]?

[luavirusfree]

I already did! ... and then quoted it. I'm just being ignored there.

[editline]24th January 2013[/editline]

That's why you see it as a quote here...

[BlkDucky]

jesus christ why did you comment literally every line

[luavirusfree]

?? What are you talking about?

[editline]24th January 2013[/editline]

If you mean "Why is there a message from you on every second line" then still, what are you talking about? For some of my threads, it is like that, but that's because I really want the answer. I have nothing else to do, right now.

I see. Still, I'm pretty sure you're more likely to get help there.

[luavirusfree]

Oh! In the script. That's because people sometimes take a script that someone else has made to give themselves an idea on how to make their own version.

[QUOTE=Mozartkugeln;39341165]I see. Still, I'm pretty sure you're more likely to get help there.[/QUOTE]

I've had this problem before, where I wasn't getting an answer in LUA. I got the answer in this thread section, instead.

[Mozartkugeln]

Do you seriously think you need to add a comment to a line that just says "end"? You're actually making it twice as hard for people to read your code by adding all that useless junk that you can [I]read from the code itself anyway[/I].

Here's some advice:
[QUOTE=Linus Torvalds]Comments are good, but there is also a danger of over-commenting. NEVER try to explain HOW your code works in a comment: it's much better to write the code so that the [I]working[/I] is obvious, and it's a waste of time to explain badly written code. Generally, you want your comments to tell WHAT your code does, not HOW. Also, try to avoid putting comments inside a function body: if the function is so complex that you need to separately comment parts of it, you should probably go back to chapter 4 for a while. You can make small comments to note or warn about something particularly clever (or ugly), but try to avoid excess. Instead, put the comments at the head of the function, telling people what it does, and possibly WHY it does it.[/QUOTE]

[editline]24th January 2013[/editline]

[QUOTE=luavirusfree;39341048][lua]texture = surface.GetTextureID "CombineHud/met_comb_ovr_2048"[/lua][/QUOTE]

You're missing the parentheses; it should be [I]surface.GetTextureID("texturepath")[/I]. [I]GetTextureID[/I] is a function, and function take arguments which you put in their parentheses. Same mistake occurs several times in the code.

I really suggest getting a book on programming and starting from scratch as it'll help you get a hang of the basics and get rid of the bad habits. If you want to go with Lua, start with [I][URL=http://www.lua.org/pil/]Programming in Lua[/URL][/I] by the language's creator.
Also, if you're looking for help on a specific issue, you should post the error message you get when you run your code. That tells people where to look: which function caused the error and on what line.
