Possible Orange Box Code Bug and Fix

Z33ky, please check this out for me.

The Toggle-Command code (3.5) seems to have a coding error for TOB in it.

You specify: CBasePlayer* pPlayer = C_BasePlayer::GetLocalClient();

This errors outs saying that GetLocalClient does not exist (same with CBasePlayer* pPlayer = UTIL_GetCommandClient() by the way).

I think I may have fixed it by changing that to C_BasePlayer *localplayer = C_BasePlayer::GetLocalPlayer();. The compile does not fail this time and Iron Sights sort of works ingame. However the weapon does not raise up to the players view, the view only gets zoomed in. I can PM you a screen on the steam forums if you need one to see what is happening. --Laughing Man 07 Jan 2010

Check out the latest few revisions for that. --z33ky 14:30, 18 January 2010 (UTC)

Renewed (fixed) Article

Fixed errors Code compiles now, ironsights and console-variables work (except for the bugs mentioned in the tutorial)

Sorry for the trouble I made by giving the variables a proper but sometimes wrong name without testing the actual code --z33ky 09:05, 22 Sep 2008 (PDT)

Wiki talk paes are usually left the same, rather then removing them after a few messages :) --Craziestdan 12:50, 22 Sep 2008 (PDT)
I wanted to clear the page because I renewed the article to a compilable level. So basicly the stuff already talked about is useless. --z33ky 13:13, 22 Sep 2008 (PDT)

not-working ConVars & bugs

Thanks z33ky for correcting the code. It still doesn't work for me though, I'm getting the same problems as Jlea. Except when I have viewmodel_adjust_enabled set to 0, the gun goes half into ironsight position but then immediately goes out again. --Johnmagicson 13:24, 22 Sep 2008 (PDT)

It completly works for me and I have an exact copy of that code. Are you sure the variables are networked correctly? (I just added a little note there) --z33ky 15:56, 22 Sep 2008 (PDT)

Oh, sorry, I assumed it would've gone into the first network table, and that was what caused all my errors and all the problems I had in game. Now it works fine, thanks z33ky!

EDIT: The only thing that doesn't work for me now is using the console commands. In Jorg's version, I could tweak the ironsight co-ordinates to find the right ones to put in my scripts, but in this one the viewmodel_adjust commands do nothing, and turning on viewmodel_adjust_enabled just makes it so I can't aim in ironsights :S --Johnmagicson 22:39, 22 Sep 2008 (PDT)

Did you update the flags to FCVAR_REPLICATED? Else set a breakpoint on the two returns in GetIronsightPositionOffset to see which one is executed, and why. --z33ky 06:02, 23 Sep 2008 (PDT)
so, does it work now? :S --z33ky 08:44, 27 Sep 2008 (PDT)

Doesnt work for me

This code doesnt work for me. when activated, when i move or turn my gun goes off in randomd irections and is usually off the screen. I dont get ironsights at all.

SImple. Your not a programmer. Otherwise you'd figure this. --Craziestdan 17:47, 30 Oct 2008 (PDT)
Are you sure you did everything in baseviewmodel_shared.cpp right? Try to use this code without any offsets - does it still happen? --z33ky 09:03, 3 Nov 2008 (PST)

ConVar Placement

Apparently it's not cool, or something, to help out people who are trying to learn through this code(even though we're reverse-engineering someone else's thousands of lines). But I'm still going to ask and hope for a quick, and hopefully helpful response. I have one sole error regarding the placement(I'm assuming) of the ConVars from [1]. Is there a more specific area I should be placing them? "After the includes" doesn't seem to be working. --Vradinolfi 06:50, 12 October 2009 (UTC)

I'm a little confused by your first sentence, but for your ConVar-problems: What exactly is the error?
It should be working just fine somewhere in the global scope.--z33ky 20:03, 16 October 2009 (UTC)
I was just pointing out how pretentious some of the other people here are, don't worry, you're actually helpful. I'm not by my dev box at the moment but it says something like "formerly undeclared identifier" I believe.
It's the only error I get, but I receive it twice and they both point to the ConVars. --Vradinolfi 07:49, 17 October 2009 (UTC)
The only thing I can think about would be that you either didn't put them in global scope, have a typographical error or that you are declaring them after defining the function that uses it.
And make sure it's not between some pre-processor directives like #ifndef CLIENT_DLL or #ifdef HL2MP or something alike. --z33ky 12:44, 17 October 2009 (UTC)

old code

not compilable

Z33ky, i followed it and it come up with doezen's of errors :( Probably because my lack of C++ expert :( Could you possibly add line numbers to each section of code? Because some parts im unsure of, so i end up adding in the wrong parts and generate a million errors. Please, add line numbers for all parts :) --Craziestdan 08:46, 14 Sep 2008 (PDT)

Could someone please add line numbers for this tutorial please?? --Craziestdan 17:32, 15 Sep 2008 (PDT)
The reason I won't add lines is, that I don't want newbies to just copy&paste that code, but understand what they are doing. Also, the lines will be wrong if there is a code-update or you already modified one of the files. You should be able to do this with knowledge of C++ and basic Source-knowledge --z33ky
Well, I'm fairly good at coding but I can't figure out why CBasePlayer::SetFov() is missing.
Could it be outdated? EDIT: It's looking for the definition of SetFOV in c_baseplayer.h instead of player.h. Any idea why?
EDITEDIT: Error: 2>..\game_shared\basecombatweapon_shared.cpp(80) : error C2039: 'SetFOV' : is not a member of 'C_BasePlayer' ::::::-Marche
This code is written for OrangeBox-based mods. I'll add this feature to an ep1-mod soon, so maybe you wanna wait or try to figure it out by yourself.
Looking at the code you'll have to paste the SetFOV between #ifdef GAME_DLL #endif and to see if it is able to change the FOV you can look at line 7396 of player.cpp (CBasePlayer::SetFOV). --z33ky 06:49, 6 Nov 2008 (PST)
Well, the crossbow works with a CBasePlayer pointer too, so I have no idea why this doesn't work... It would be great if you could port it for others though! Ill mess with it until you take a look, my mod won't compile, bone_setup.sbr won't regenerate for some reason..... I've switched accounts on the steam forums, I am formerly C++Ftw and now known as Mandelgroove. All forms of Marche were taken and that was a very stupid name ;-;. -Marche
Could you write it your way? I can't get it to work. I still don't see why the crossbow scope works and this doesn't...
FIXED: GAME_DLL isn't defined so it does nothing. Just put #ifndef CLIENT_DLL and #endif around EnableIronsights() and DisableIronsights()

ConVars not working

Hey z33ky, the tutorial works great and I'd like to thank you so much for putting this up. One problem is the console commands do not work ingame, they have no effect.--JLea 21:27, 19 Sep 2008 (PDT)
You need to set viewmodel_adjust_enabled 1 and for that you need sv_cheats to be 1, too. --z33ky 01:28, 20 Sep 2008 (PDT)

EDIT: And you have to make viewmodel_adjust_fov to a ConCommand, changing the fov if viewmodel_adjust_enables is 1.

I'm not that stupid :P. Even if sv_cheats are 1 and viewmodel_Adjust_Enabled is 1 it doesn't do anything. Acutally if adjust_enabled is set to 1, pressing the ironsights button has no effect even if I type new values in. --JLea 02:15, 21 Sep 2008 (PDT)
I'm not sure what's the problem then - I guess you'll have to debug your way through. --z33ky 05:17, 21 Sep 2008 (PDT)

not compilable

The other tutorial was harder to follow, but it worked for me... This one just gave me tons and tons of errors. I have some knowledge in programming in C, and I have made a few mods for hl2 before. I'm pretty sure I followed every step correctly.

The errors tell me there are undeclared identifiers for several variables, and when I look through your code, I can't find any part where you declare some of them, such as "m_bIsIronsighted"... Am I supposed to do some of the coding work myself? I thought this was just an easy copy and paste tutorial :(

EDIT: I also noticed there are some spelling errors, such as m_bIsIronsighted is spelled incorrectly as m_bIsIronighted and "position" is sometimes spelled as "positon"... correcting these spelling errors has reduced the amount of errors for me, i'm still looking through the code. I'm just curious, has anyone tested this and got the same results as the other tutorial?

EDIT: after correcting several spelling errors, i finally got it to compile... but in game when i toggle ironsights, it does nothing!.. I modified some of the code and I managed to get it to go in and out of ironsight aiming, but it can never stay! It just makes the gun go into ironsight position for a second and then immediately goes out. --Johnmagicson 22:09, 21 Sep 2008 (PDT)

Undeclared identifiers?

I can't seem to get this work. The compiler just whines that all of the variables and functions are undeclared, even though they are declared, I've checked all of them, and tried them in a few different places. Any idea why this could be happening? I've also made sure they're not misspelt. --Dragory 12:43, 14 January 2010 (UTC)

Which variables does the compiler deem as undeclared? --z33ky 14:30, 18 January 2010 (UTC)
Every variable added in this tutorial --Dragory 10:16, 13 March 2010 (UTC)
Upload some header (let's say basecombatweapon_shaded.h) to a pastebin and post the link, so I can take a look at it. --z33ky 13:45, 14 March 2010 (UTC)


Where is weapon_smg1.txt located, or is it supposed to be .cpp or .h? Adam.GameDev
