A portfolio would be interesting, gonna check on doing that one day.

I got this idea in my mind, when i saw popular mods opening Patreons to continue development. Well yes, these are big projects and is required a lot of time for their final realese, but i was thinking... what about a freelance job? like, someone ask you to program a weapon, an entity or a NPC in their mod for a few bucks (of course, for a very very cheap price).
Tho most of the projects i've saw where made by a lot of people with no financial motivations, i see a few cases where someone was willing to pay money just to code a few things (at least on Moddb), so my question is: How probable is to find people who is interested in your coding habilities and wants you to do a commission in the Source engine? or even more... in the Goldsrc engine? They are very old engines and i don't think there's that much demand for coding of these like in Unreal or Unity. (Also because most of the people who moddify very old games do it for their own projects istead of economic reasons, just like i do, i don't really want to tie my projects with monetization)

Hey, just wanted to say that i find my solution months ago.
What i wanted is to show the amount of grenades without select them, so here's my code writed in SendAmmoUpdate in player.cpp :

void CBasePlayer::SendAmmoUpdate(void)
{
for (int i=0; i < MAX_AMMO_SLOTS;i++)
{
if (m_rgAmmo[i] != m_rgAmmoLast[i])
{
m_rgAmmoLast[i] = m_rgAmmo[i];

ASSERT( m_rgAmmo[i] >= 0 );
ASSERT( m_rgAmmo[i] < 255 );

MESSAGE_BEGIN(MSG_ONE, gmsgGrenades, NULL, pev);//send message with the hitgroup they were just hit
WRITE_BYTE(0); //For some reason, there is some weapon ammo that is impossible to get his index, so instead of writing the grenade index, we just put a 0
`WRITE_BYTE(V_max(V_min(m_rgAmmo[GetAmmoIndex("Hand Grenade)"], 254), 0));`
MESSAGE_END();

// send "Ammo" update message
MESSAGE_BEGIN( MSG_ONE, gmsgAmmoX, NULL, pev );
WRITE_BYTE( i );
WRITE_BYTE( V_max( V_min( m_rgAmmo[i], 254 ), 0 ) ); // clamp the value to one byte
MESSAGE_END();
}
}
}

The gmsgGrenades can be replaced whit gmsgAmmoX , but i created a separated code just in case.

Hey, i was really interested in adding things to the HUD, and tried to create a new ammo counter for a specific weapon.
I take a look at the code and see the DrawHudNumber that some parts of the HUD like the ammo, health and battery have, so i was triyng to get this thing to work but it doesnt seems to have a result.

I tried to take a look at the Internet to see a way on getting my HUD to work, but surprisingly, i didn't find any, and the ones on this site seems to just show things like adding sprites similar to the flash light or the CS radar.

So i wanted to ask if someone haves a better idea on how these things work or if someone has a guide that can help me.

Hey, just fixed it, and i can't belive how i fixed it.
First, i writted the code much better and added a CBasePlayer to my void, which solved most of the problem, but then this message appeared: No model 175!
I spent hours trying to figure out the problem, and the answer is kinda surprising.
You see, the sprite wasn't supposed to be precached in the player's Precache(), so i precached the sprite in weapons.cpp, added an extern short to weapons.h and done!

//call medic
void CBasePlayer::MedicToogle(CBasePlayer* pPlayer)
{

if (gpGlobals->time < m_flCounter)
{
return;
}

switch (RANDOM_LONG(1, 2))
{
case 1:
EMIT_SOUND(ENT(pev), CHAN_VOICE, "speech/saveme1.wav", 1, ATTN_NORM);
m_flCounter = gpGlobals->time + 3.5;
break;
case 2:
EMIT_SOUND(ENT(pev), CHAN_VOICE, "speech/saveme2.wav", 1, ATTN_NORM);
m_flCounter = gpGlobals->time + 3.5;
break;
}

MESSAGE_BEGIN(MSG_BROADCAST, SVC_TEMPENTITY, pPlayer->pev->origin);
WRITE_BYTE(TE_PLAYERATTACHMENT);
WRITE_BYTE((BYTE)pPlayer->entindex());
WRITE_COORD(45);
WRITE_SHORT(g_sModelIndexMedic);
WRITE_SHORT(30);
MESSAGE_END();

}

This is the new code.

Yeah, i'm kinda lost... tried to do that, but i just get errors and crashes, i think i'm missing something.
i'll see if i can figure this out later.

Edit: Still on this problem, the message directly doesn't recognize any model/sprite given and just finded this on my console: No model -24064! , so im kinda stuck now.

MESSAGE_BEGIN(MSG_BROADCAST, SVC_TEMPENTITY); //here we start a message which draws a beam behind a player

WRITE_BYTE(TE_PLAYERATTACHMENT); //sets the beam to follow the entity(player)
WRITE_SHORT(entindex()); // entity
WRITE_COORD(20);
WRITE_SHORT(m_mCall); //model/sprite
WRITE_BYTE(20); //life

MESSAGE_END(); //ends the message we started above

m_mCall already has a precache with a sprite that worked, I tried other messages that were not "TE_PLAYERATTACHMENT" and they managed to make the sprite appear (to a certain extent), so I think something is misspelled.
I'm pretty sure i'm doing something wrong but i don't know what.

Hey, great everyone, I was doing a command where if you press a specific key, the player would ask for help from a medic just like in TFC or Sven Coop.

//call medic
void CBasePlayer::MedicToogle(void)
{
CSprite * m_pCall = NULL;

if (gpGlobals->time < m_flCounter)
{
return;
}

//const Vector Position = pev->origin + Vector(0, 45, 0);

switch (RANDOM_LONG(1, 2))
{
case 1:
EMIT_SOUND(ENT(pev), CHAN_VOICE, "speech/saveme1.wav", 1, ATTN_NORM);
m_flCounter = gpGlobals->time + 3.5;
break;
case 2:
EMIT_SOUND(ENT(pev), CHAN_VOICE, "speech/saveme2.wav", 1, ATTN_NORM);
m_flCounter = gpGlobals->time + 3.5;
break;
}
if (m_pCall == NULL)
{
m_pCall = CSprite::SpriteCreate("sprites/saveme.spr", Vector(0, 0, 45), TRUE);
if (m_pCall)
{
m_pCall->SetTransparency(kRenderTransAdd, 255, 255, 255, 255, kRenderFxNoDissipation);
m_pCall->SetAttachment(edict(), 1);
m_pCall->SetScale(0.5);
m_pCall->TurnOn();
m_pCall->AnimateAndDie(20.0f); // different framerates = more visual variation
}
}
}

This inside` "Player.cpp"`.
Thing is that I'm using a sprite called "saveme.spr", from the TFC files, and it doesn't work as it should. This one remains invisible and does not appear, try with other sprites and most of them did appear when pressing the key, from what I understand, there's some sprites that must be added in a different way, like the "voiceicon.spr", so I wanted to know If any of you have any ideas and can tell me about this problem.

I'll wait for your answers.

Now i already fixed it, it was a problem on the ChangePlayerTeam function, maybe i could show something on the way!

Hi, i was modding in my half life build for a team play game, and i wanted my team classes to have different player models, in this case, i used the "t_team" code (that i declared on player.h and used to allow my classes to have different weapons after spawnning) to edit the ChangePlayerTeam and the ClientUserInfoChanged from "teamplay_gamerules.cpp"

The weapon player class code on "teamplay_gamerules.cpp":

BOOL CHalfLifeTeamplay :: ClientCommand( CBasePlayer *pPlayer, const char *pcmd )
/Blah Blah Blah Code/
else if (FStrEq(pcmd, "scout") || FStrEq(pcmd, "soldier") || FStrEq(pcmd, "medic"))
{
/Blah Blah Blah Code/

if (FStrEq(pcmd, "scout"))
{
pPlayer->t_team = 1;
}

if (FStrEq(pcmd, "soldier"))
{
pPlayer->t_team = 2;
}

if (FStrEq(pcmd, "medic"))
{
pPlayer->t_team = 3;
}

And then in "multiplay_gamerules.cpp" i added on the part if (addDefault) something like this:

if (pPlayer->t_team == 1)
Code to give for the player

This code worked for the weapons, so i thought that would work for other things, but im having a little issue.
https://www.youtube.com/watch?v=cFt1XcfDQfg
As you see in this video, the model of the class doesn't change to the default model until I manually change the model to another one that I'm not currently using.
The code in theory works, but not as it should, I'm sure something is missing, but I don't know what it is, this is the code for class model change:

void CHalfLifeTeamplay::ChangePlayerTeam( CBasePlayer *pPlayer, const char *pTeamName, BOOL bKill, BOOL bGib )
{
int damageFlags = DMG_GENERIC;
int clientIndex = pPlayer->entindex();

if ( !bGib )
{
damageFlags |= DMG_NEVERGIB;
}
else
{
damageFlags |= DMG_ALWAYSGIB;
}

if ( bKill )
{
// kill the player, remove a death, and let them start on the new team
m_DisableDeathMessages = TRUE;
m_DisableDeathPenalty = TRUE;

entvars_t *pevWorld = VARS( INDEXENT(0) );
pPlayer->TakeDamage( pevWorld, pevWorld, 900, damageFlags );

m_DisableDeathMessages = FALSE;
m_DisableDeathPenalty = FALSE;
}

// copy out the team name from the model
strncpy( pPlayer->m_szTeamName, pTeamName, TEAM_NAME_LENGTH );

if (pPlayer->t_team == 1)
{
g_engfuncs.pfnSetClientKeyValue(clientIndex, g_engfuncs.pfnGetInfoKeyBuffer(pPlayer->edict()), "model", "scout");
}
else if (pPlayer->t_team == 2)
{
g_engfuncs.pfnSetClientKeyValue(clientIndex, g_engfuncs.pfnGetInfoKeyBuffer(pPlayer->edict()), "model", "soldier");
}
else if (pPlayer->t_team == 3)
{
g_engfuncs.pfnSetClientKeyValue(clientIndex, g_engfuncs.pfnGetInfoKeyBuffer(pPlayer->edict()), "model", "medic");
}
//g_engfuncs.pfnSetClientKeyValue(clientIndex, g_engfuncs.pfnGetInfoKeyBuffer(pPlayer->edict()), "model", pPlayer->m_szTeamName);
g_engfuncs.pfnSetClientKeyValue( clientIndex, g_engfuncs.pfnGetInfoKeyBuffer( pPlayer->edict() ), "team", pPlayer->m_szTeamName );

// notify everyone's HUD of the team change
MESSAGE_BEGIN( MSG_ALL, gmsgTeamInfo );
WRITE_BYTE( clientIndex );
WRITE_STRING( pPlayer->m_szTeamName );
MESSAGE_END();

MESSAGE_BEGIN( MSG_ALL, gmsgScoreInfo );
WRITE_BYTE( clientIndex );
WRITE_SHORT( pPlayer->pev->frags );
WRITE_SHORT( pPlayer->m_iDeaths );
WRITE_SHORT( 0 );
WRITE_SHORT( g_pGameRules->GetTeamIndex( pPlayer->m_szTeamName ) + 1 );
MESSAGE_END();
}
void CHalfLifeTeamplay::ClientUserInfoChanged( CBasePlayer *pPlayer, char *infobuffer )
{
// an observer can change a lot, but isn''t visible so hasn''t got to do much here

if (pPlayer->m_afPhysicsFlags & PFLAG_OBSERVER)

return;

// prevent skin/color/model changes

char* mdls = g_engfuncs.pfnInfoKeyValue(infobuffer, "model");

//if the model name and the teamname are the same then return

if (pPlayer->t_team == 1)
{
if (!stricmp(mdls, "scout"))
return;
}
if (pPlayer->t_team == 2)
{
if (!stricmp(mdls, "soldier"))
return;
}
if (pPlayer->t_team == 3)
{
if (!stricmp(mdls, "medic"))
return;
}

//else make sure the player model is the same as the teamname
if (pPlayer->t_team == 1)
{
g_engfuncs.pfnSetClientKeyValue(pPlayer->entindex(), g_engfuncs.pfnGetInfoKeyBuffer(pPlayer->edict()), "model", "scout");
}
else if (pPlayer->t_team == 2)
{
g_engfuncs.pfnSetClientKeyValue(pPlayer->entindex(), g_engfuncs.pfnGetInfoKeyBuffer(pPlayer->edict()), "model", "soldier");
}
else if (pPlayer->t_team == 3)
{
g_engfuncs.pfnSetClientKeyValue(pPlayer->entindex(), g_engfuncs.pfnGetInfoKeyBuffer(pPlayer->edict()), "model", "medic");
}
//g_engfuncs.pfnSetClientKeyValue(pPlayer->entindex(), g_engfuncs.pfnGetInfoKeyBuffer(pPlayer->edict()), "model", pPlayer->m_szTeamName);
}

Now i solved the problem, i used bad the UTIL_PrecacheOther();.
Maybe i could do a video showing the nailgun.

Ok, so i already found a way to solve the cl_dll compilation problem, the client was detecting a cvar created by me in the player.h, that basically enables semiclip, because client wasnt capable to process this new cvar, the compilation gived errors, so i added an #ifndef / #endif on the void... and it works!

Now my main problem is still how to solve the issue of firing the projectile:

Host_Error: PF_precache_model_I: 'models/nail.mdl' Precache can only be done in spawn functions

So, you see... i was trying to make a nail gun with no success, i always get this code error every time:

1>hl_weapons.obj : error LNK2001: unresolved external symbol "public: virtual void __thiscall CBasePlayer::Touch(class CBaseEntity *)" (?Touch@CBasePlayer@@UAEXPAVCBaseEntity@@@Z)
1>Debug\hl_cdll\client.dll : fatal error LNK1120: 1 unresolved externals

So at one point i give up and scrapped all the code, doing something more "easy" instead, and by easy i mean copy pasting the crossbow code. It did compile well, by the exception of the client syde, that get me the same error, so i just change the hldll. Everything was running preaty well, until it was the moment to shoot the gun:

Host_Error: PF_precache_model_I: 'models/nail.mdl' Precache can only be done in spawn functions

The only thing i want to know is what and how to solve this issue, if you ask what the code is, well... is the same as a Crossbow. But now the thing is... if the way to solve this problem is to compile the cl_dll, well... TOO BAD! because i dont know what is the main cause of the problem.
You would say that the weapon is bad writed on the hl_weapons.obj, like i thinked it was, but then i thinked on compiling the cl_dll of a separated source code, where i didnt even touch the client or the regular dlls. And this happens:

1>hl_weapons.obj : error LNK2001: unresolved external symbol "public: virtual void __thiscall CBasePlayer::Touch(class CBaseEntity *)" (?Touch@CBasePlayer@@UAEXPAVCBaseEntity@@@Z)
1>Debug\hl_cdll\client.dll : fatal error LNK1120: 1 unresolved externals

It results... the main base code for the client that i worked whit was busted from the start all along, i need to clarify that im not using the SoloKillersSDK, im using the 2013 Valve realease.
If you know how to solve the problem whithout deleting all my progress, i will thank you a lot, words cannot describe my sheer fucking confusion right now...

theres more if you need:

Well you see, i tried to replicate the quake nail of Deathmatch Classic to create this weapon... So you will see enough copy paste of the code triying to replicate it on the HL base code. Some of the functions for the nail projectiles where already on the Client files, so i dont know how much this causes the main problem. I don't even think this weapon shoots even, i really need someone to diagnose this terribleness.

Hi, i recently created an account here just to ask for help about creating a Half-Life Weapon.
You see, im working on a nail gun like in TFC and because im really amateur at this, i get this error when compiling the cl_dll.

`1>hl_weapons.obj : error LNK2001: unresolved external symbol "public: virtual void __thiscall CBasePlayer::Touch(class CBaseEntity *)" (?Touch@CBasePlayer@@UAEXPAVCBaseEntity@@@Z)
1>Debug\hl_cdll\client.dll : fatal error LNK1120: 1 unresolved externals`

Im most secure that is something simple, but i can't find anything related to it, so i'm completely lost.
Can someone know the reason?
