| 00:49 | <@gnolam> | Back to the old drawing board with your collision functions then? |
| 00:49 | <@Derakon> | Actually, so far that hack I put it specifically for the toestubbing problem seems to be working. |
| 00:50 | <@Derakon> | The screen jitter was a separate issue stemming from the fact that SDL only renders integer numbers of pixels. |
| 00:54 | <@gnolam> | Yes. But the jittering in those situations depends on how you handle collision with the ground. :) |
| 00:54 | <@gnolam> | And I'm getting jitter in my dose rate readings. Blergh. :P |

| 12:12 | | * AnnoDomini scratches head. Will UTF-8 correctly do Central European characters? |
| 12:13 | <@jerith> | UTF-8 will correctly do the entire unicode range. |
| 12:14 | <@jerith> | You may need a suitable typeface to map the codepoints into appropriate glyphs, however. |
| 12:15 | <@jerith> | ??? |
| 12:15 | <@AnnoDomini> | I'll rephrase. I'm setting up a MySQL server and I have to select a default character set. I know my database will have CE characters. I want them to be properly represented when put on a website. |
| 12:16 | <@jerith> | That's not the db's job. |
| 12:16 | <@AnnoDomini> | jerith: That looks like the bastard child of a question mark and an exclamation mark with headphones on. |
| 12:18 | <@jerith> | It's an interrobang (0x203D) surrounded by a matched pair of black bullets (0x204C, 0x204D). |
| 12:23 | <@jerith> | I'm rather partial to 0x26B0, also: ? |
| 12:24 | <@AnnoDomini> | That's a thin rectangle. |
| 12:24 | <@jerith> | Then your font isn't big enough. The symbol name is COFFIN. ;-) |
| 12:25 | <@AnnoDomini> | Is it just me, or is MySQL's producer being a dick in requiring a slew of personal data just to download the fucking free version of the software? |
| 12:25 | <@jerith> | aptitude install mysql-server |
| 12:25 | <@jerith> | yum install mysql-server (I thing) |
| 12:25 | <@AnnoDomini> | Not on Lunix, dude. |
| 12:26 | <@jerith> | ? |
| 12:27 | <@AnnoDomini> | Unhappy face. |
| 12:27 | <@jerith> | You're probably bettor off grabbing a WAMP stack, then. |
| 12:27 | <@AnnoDomini> | A what? |
| 12:28 | <@jerith> | There are a bunch of Apache/MySQL/PHP packages for Windows. |
| 12:28 | <@jerith> | They come with pretty installers and sane configurations, or so I am told. |
| 12:29 | <@jerith> | However, my battery is about to be empty. |
| 12:31 | <@jerith> | ? <-- Have some benzine. |
| 12:32 | | * AnnoDomini the hell out of MySQL. What DON'T you understand about 'create database library;'?! |
| 12:33 | <@jerith> | s/?!/?/ |
| 12:36 | <@jerith> | Anyways, you need to make sure your app is using unicode rather than ASCII. |
| 12:37 | <@AnnoDomini> | Eh. I don't think the teacher will be bothered much by silly symbols instead of characters much. |
| 12:38 | | * AnnoDomini makes sure to go to the bloody consultations, because he's stumbling over setting up a god-damned server, even. |
| 12:38 | <@jerith> | And now I must flee. Cheerio. |
| 13:03 | <@AnnoDomini> | Mm'kay. I'm connected to the SQL shell of postgreSQL, but how the fuck do I tell where I am? |
| 13:03 | <@AnnoDomini> | It fails to load a script file given with an absolute path. |
| 13:13 | <@AnnoDomini> | Finally. How the hell was I supposed to KNOW that using the wrong slash? It's a fucking local path, the obvious choice is \. |
| 13:15 | < Tarinaky> | I expect it was mentioned in the manual. |
| 13:17 | <@AnnoDomini> | I don't care if it was mentioned in the 500 page manual. I care that the error message was absolutely unhelpful, as was the \help command. |
| 13:31 | | * AnnoDomini wonders how the hell to make a table INSIDE the database he created. |
| 13:31 | <@AnnoDomini> | It seems that it's for some reason creating a database, and a table independently. |
| 13:56 | <@jerith> | AnnoDomini: Most apps accept '/' as a path separator in Windows, because '\' is an escape character. |
| 14:02 | < Alek> | what's that thin interrobang with a caret hat that is enclosed on the right? |
| 14:03 | < Alek> | oh wate. |
| 14:03 | < Alek> | ?! |

| 19:53 | <@AnnoDomini> | TextBox.cpp:24: warning: comparison between signed and unsigned integer expressi |
| 19:53 | <@AnnoDomini> | ons |
| 19:54 | <@AnnoDomini> | Should I be worried? |
| 19:54 | <@jerith> | Only if it's likely to be an issue. |
| 19:55 | <@jerith> | I tend to jump through hoops to avoid warnings, just because many of them are real problems that I don't want to mask with craploads of noise. |
| 19:57 | <@AnnoDomini> | I don't think it's an issue. |
| 20:01 | <@AnnoDomini> | Eh. I think I'll use abs() or something to get rid of this. |
| 20:02 | <@AnnoDomini> | abs() was in math.h, right? |
| 20:02 | <@ToxicFrog> | man 3 abs and find out. |
| 20:02 | <@AnnoDomini> | What? |
| 20:03 | <@ToxicFrog> | The command "man 3 abs" will give you the manual page for abs in section 3 of the manual (the C standard library) |
| 20:03 | <@ToxicFrog> | Among other things, that tells you what headers and defines you need, if any. |
| 20:03 | <@AnnoDomini> | On Windows? |
| 20:04 | <@gnolam> | AnnoDomini: or just cast the offending variable? |
| 20:04 | <@ToxicFrog> | Oh. No cygwin/msys? |
| 20:04 | <@ToxicFrog> | In that case |
| 20:04 | <@ToxicFrog> | NAME |
| 20:04 | <@ToxicFrog> | abs, labs, llabs, imaxabs - compute the absolute value of an integer |
| 20:04 | <@ToxicFrog> | SYNOPSIS |
| 20:04 | <@ToxicFrog> | #include <stdlib.h> |
| 20:04 | <@ToxicFrog> | int abs(int j); |
| 20:05 | <@AnnoDomini> | Curiously, it works without including stdlib. |
| 20:05 | <@ToxicFrog> | Something else you're including might be including stdlib. |
| 20:05 | <@AnnoDomini> | I see. So I'd better. |
| 20:05 | <@gnolam> | *cough*cast*cough* |
| 20:06 | <@gnolam> | If it's not safe to cast, it's not safe to just abs() it either. |
| 20:06 | <@AnnoDomini> | Cast? You mean that thing with the very funky syntax? |
| 20:06 | <@ToxicFrog> | Oh right, you're in C++ |
| 20:07 | <@ToxicFrog> | So, first of all, you want to include <cstdlib> |
| 20:07 | <@AnnoDomini> | (abs()ing took care of the issue.) |
| 20:08 | <@gnolam> | (type)(variable) |
| 20:08 | <@gnolam> | (And the parentheses around the variable are pretty much optional) |
| 20:09 | <@ToxicFrog> | In C++, you can also static_cast<type>(var) |
| 20:09 | <@AnnoDomini> | That was what I meant. |
| 20:09 | <@AnnoDomini> | Funky. |
| 20:09 | <@AnnoDomini> | ToxicFrog: Where am I to include <cstdlib>? The file where I'm using a cast? |
| 20:10 | <@ToxicFrog> | The file where you're using abs |
| 20:11 | <@ToxicFrog> | For using C functions, if the C include is <foo.h>, the C++ include is <cfoo> |
| 20:11 | <@AnnoDomini> | I see. |
| 20:12 | <@gnolam> | And I maintain that it should be a cast and not an abs() - unless you're Doing Something Wrong that leads to the warning. |
| 20:13 | <@gnolam> | (But this is C++, so I assume it's just being anal for anal retentiveness' sake) |
| 20:13 | <@AnnoDomini> | I'm not doing anything wrong. I'm checking if the length of the substring is less than what I demanded, thus signifying that the substring contains the end of the base string. |
| 20:16 | <@ToxicFrog> | ...what are you using abs for, then? |
| 20:17 | <@ToxicFrog> | Now I'm worried and want to see your code. |
| 20:19 | <@AnnoDomini> | I'm using casting now, since it looks nicer. |
| 20:20 | <@AnnoDomini> | http://pastie.org/437014 |
| 20:33 | <@AnnoDomini> | How insane is it? |
| 20:34 | <@ToxicFrog> | Actually, not as insane as I feared. |
| 20:35 | <@ToxicFrog> | The problem stems from the fact that you have rows and cols as int rather than unsigned int |
| 20:36 | <@ToxicFrog> | (well, the warning, it's not actually a problem) |
| 20:36 | <@ToxicFrog> | And .length() returns an unsigned int, or more likely a size_t |
| 20:37 | <@AnnoDomini> | Well, one way or another, I'm comparing columns and lastSpace which has to be an int if I understood the find_last_of() documentation correctly. |
| 20:39 | <@ToxicFrog> | size_t find_last_of ( const string& str, size_t pos = npos ) const; |
| 20:39 | <@ToxicFrog> | It returns a size_t. |
| 20:39 | <@ToxicFrog> | Which is generally something like "unsigned long int" |
| 20:40 | <@AnnoDomini> | And what does it return if it doesn't find? |
| 20:44 | <@ToxicFrog> | string::npos, which is the greatest possible value of a size_t and also -1. |
| 20:44 | <@AnnoDomini> | So yeah. |
| 20:47 | <@ToxicFrog> | So, there's pretty much no reason for any of your numbers there to be signed. |
| 20:49 | <@ToxicFrog> | (and len and lastSpace should ideally be size_t) |
| 20:50 | <@AnnoDomini> | Eh. It works now. I might fix it sooner or later, but not now. |
| 20:53 | <@ToxicFrog> | Yeah, it'll work fine as written, it's just...style. |
| 21:19 | <@AnnoDomini> | Mm'kay. Thanks. |
| 21:45 | <@AnnoDomini> | Hmm. I'm fuzzy here - if I wanted to get a hexadecimal value as an argument, what type would I use? int? |
| 21:45 | <@AnnoDomini> | I mean, I've got things like 0x009999FF for colours. |
| 21:47 | <@jerith> | int or long, I suppose. |
| 21:49 | <@McMartin> | Are there any particular libraries you're using here? |
| 21:49 | <@McMartin> | And how portable are you trying to be? |
| 21:51 | <@McMartin> | uint32_t is the UNIX standard one, but it's not universally respected. SDL has UInt32, which will be. |
| 21:52 | <@AnnoDomini> | Libraries: SDL, SDL_gfx. |
| 21:53 | <@AnnoDomini> | I suppose it'd be good to have portability to Linux, since a friend of mine showed interest in testing. |
| 21:59 | <@gnolam> | Haha! Take /that/, c__hl_weapon_stubs.h! |
| 21:59 | <@gnolam> | Now I just need to figure out how to send a boolean... |
| 22:06 | <@McMartin> | Yeah, if you're using SDL, use the UInt32 type for 32-bit colors. |
| 22:06 | <@McMartin> | I forget offhand if the I is capitalized. |
| 22:07 | <@McMartin> | (If it were DirectX, I'd say use the Windows DWORD type.) |
| 22:20 | <@AnnoDomini> | It isn't. |
