Welcome to the Breakdown

Howdy! Today I'm going to break down how I personally make custom weapon scripts & sound files for HL2.

As a preface, you're going to need to know some basic editing of the scripts found in HL2, how to create/edit script files, and to have some basic replacements for HL2. I'll leave you to find your own content, as it isn't in the scope of this tutorial.

Anything in bold italic text is an exact name or a code bit, as Steam Guides lack an in-line code highlight function. Keep that in mind.

Breaking It Down

To start with, I'm going to break down the essentials of what we're going to be doing, and what it means.

Giving weapons custom damage/ammo - editing the skill_manifest.cfg file.
Giving weapons custom properties - editing the relevant weapon_*.txt files.
Giving weapons custom sound script files - editing the game_sounds_manifest.txt file.
Giving weapons custom fonts - editing the clientscheme.res file.

Why We're Breaking It Down

Now, I'll go into the reasons on why we need to break these steps down:

The ammo/damage commands are skill console commands (commonly prefixed with sk_*), and as such the easiest way to set these on launch is using a config file. As we're editing skill commands, we're going to add our custom stuff to skill_manifest.cfg
The weapon scripts control the magazine sizes of the weapons, the ammo type used, and the sounds just to name a few. We can edit most of the functions related to the weapon's appearance here, even changing the default model paths. However, the accuracy and fire rate are off limits via these scripts, so we can't edit those.
To add additional sound script files in the least destructive way possible to the base game, we need to add additional entries to the game_sounds_manifest.txt file. The manifest is essentially the master file that controls what the game will load and what it won't load. Anything not cached in the manifest will likely not load.
To add or edit additional HUD icons for the weapons in HL2, you'll need to edit the clientscheme.res file. Adding a font to this file is one of the easiest things to do when editing this file, and I'll go into that.

First Steps

This entire tutorial is largely reliant on the SteamPipe custom folder feature. Each custom folder can have an entire setup for itself, which means you can keep your SMG stuff in one, your Pistol in another, and your Shotgun in a third, and so on. This enables us to use the skill commands, weapon scripts, and sound script files independently with each weapon. Modularity is our friend here.

For the sake of this tutorial, create a folder in your hl2/custom folder named weapon_tutorial. Create folders inside the weapon_tutorial folder named cfg and scripts. For now, we're going to keep the weapon editing just down to the basics for the sake of simplicity.

Adding Custom Settings to the Weapons

First, we need to open up our skill_manifest.cfg file inside our hl2/cfg/ folder. It should only contain the following by default:

exec skill.cfg

In either case, add the following lines to the skill_manifest.cfg file:

// Slot 0 exec skill/crowbar exec skill/physcannon exec skill/stunstick // Slot 1 exec skill/pistol exec skill/357 exec skill/alyxgun // Slot 2 exec skill/smg1 exec skill/ar2 // Slot 3 exec skill/shotgun exec skill/crossbow exec skill/annabelle // Slot 4 exec skill/frag exec skill/slam exec skill/rpg // Slot 5 exec skill/bugbait

Each of these lines independently control the weapons in HL2, to prevent them from being overlapped by another weapon. The exec command tells the skill_manifest.cfg file to run another config file; in this case, one for each weapon in HL2. Modularity is our friend in the case that you want to only edit one weapon and not the rest.

You probably noticed I included alyxgun, annabelle, slam, and stunstick. While these aren't included as player-usable weapons in HL2 by default, editing them will affect the NPCs that use them. Annabelle is used by Father Grigori and uses the .357 weapon settings, and the Stunstick is used by the Civil Protection NPCs in the early chapters. Having these entries allows you to control their use in game for the NPCs.

The additional perks of this are that if the specified config file doesn't exist, it will simply be ignored on game load.

A Preliminary Example

Here's an example of what one of these files would contain; in this case, the cfg/skill/shotgun.cfg file:

sk_plr_dmg_buckshot 15 sk_npc_dmg_buckshot 3 sk_max_buckshot 32 sk_plr_num_shotgun_pellets 7

This would set the damage players do with shotgun ammo to 15, the damage NPCs do to 3, and the max amount of ammo carried to 32 shells. The fourth and final command sets the number of pellets each shot fires, but I've kept it at the default of 7 for this. Each weapon in HL2 has their own set of commands, so search the sk_* prefix for them.

Editing the Weapon Script

We're going to be editing the Shotgun for this section as well, so open up your hl2/scripts/weapon_shotgun.txt file. You'll see all the settings used to control the weapon script that we can change here.

In my case, I have replaced my Shotgun with a proper SPAS-12. I have changed my weapon script accordingly:

////////////////////////////// // SPAS-12 ////////////////////////////// weapondata { printname "SPAS-12" viewmodel models/weapons/v_shotgun.mdl playermodel models/weapons/w_shotgun.mdl anim_prefix shotgun bucket 3 bucket_position 0 bucket_360 1 bucket_position_360 1 clip_size 8 default_clip 0 primary_ammo buckshot weight 0 rumble 5 item_flags 38 sounddata { // When the player fires single_shot Weapon_Shotgun.Single // When an NPC fires single_shot_npc Weapon_Shotgun.Single // When a player fire both barrels / alt-fire double_shot Weapon_Shotgun.Single // When an NPC fires both barrels / alt-fire double_shot_npc Weapon_Shotgun.Single // When the player reloads reload Weapon_Shotgun.Reload // When an NPC reloads reload_npc Weapon_Shotgun.Reload // Dry-fire empty Weapon_Shotgun.Empty // Special sound 1 special1 Weapon_Shotgun.Special1 } texturedata { weapon { font weaponicons character b } weapon_s { font weaponiconsselected character b } weapon_small { font weaponiconssmall character b } ammo { font weaponiconssmall character s } crosshair { font crosshairs character Q } autoaim { file sprites/crosshairs x 0 y 48 width 24 height 24 } } }

The weapon script function of Source is an entirely different part of the engine that is outside the scope of this tutorial, so some additional research on the part of the end user would be prudent to squeeze the most out of your custom content.

Adding Custom Sound Scripts

As I mentioned, the game_sounds_manifest.txt file is incredibly important. How important? If you have a file replacing the root folder's manifest, no other manifest file will load. Some custom weapons found around the internet are guilty of this, and it can at times cause the entire library of episodic sounds from EP1 & EP2 to not load. It's really important not to ♥♥♥♥ this up.

The easiest way to follow this tutorial, would be just to find the game_sounds_manifest.txt file inside the hl2/scripts/ folder and add the following at the very bottom before the closing bracket:

// Custom Weapon Scripts precache_file "scripts/sounds/crowbar.txt" precache_file "scripts/sounds/physcannon.txt" precache_file "scripts/sounds/stunstick.txt" precache_file "scripts/sounds/pistol.txt" precache_file "scripts/sounds/357.txt" precache_file "scripts/sounds/alyxgun.txt" precache_file "scripts/sounds/smg1.txt" precache_file "scripts/sounds/ar2.txt" precache_file "scripts/sounds/shotgun.txt" precache_file "scripts/sounds/crossbow.txt" precache_file "scripts/sounds/annabelle.txt" precache_file "scripts/sounds/frag.txt" precache_file "scripts/sounds/slam.txt" precache_file "scripts/sounds/rpg.txt" precache_file "scripts/sounds/bugbait.txt"

These lines tell the manifest to look inside hl2/scripts/sounds/ for individual sound script files for each weapon. As in the case of the skill_manifest.cfg commands, if the file isn't found - it simply doesn't load. You'll see a red line for each missing file in the console on load, and that's all.

You'll need to edit EP1 & EP2's manifest files as well at some point. If you're an advanced user who knows what they're doing, you could merge the episodic manifest files with the HL2 manifest to make editing them simpler, but I won't ask that here as it's outside the scope of this tutorial.

Adding Custom HUD Fonts

The scalable vectors used in HL2 & other Source games for their weapon HUD bucket icons are made through custom font files. This allows them to work on a variety of resolutions and look as crisp as normal on either a 4:3 or a 21:9 screen. Adding these fonts takes a bit more work, as they have to made in a dedicated font creation program.

Creating fonts is another school of thought for another time, but adding custom fonts for each weapon is not impossible. I personally use a program called FontForge as it's free to use, but you can use whatever you are comfortable with. There are no right or wrong answers, just different answers.

I've saved this step for last, as it'll likely be the least used portion of this tutorial, but I'm including it for the sake of completeness.

To add custom fonts, you first need to open up the hl2/resource/clientscheme.res file. To Valve's credit, you can actually easily add fonts in a specialized block at the bottom:

//////////////////////// CUSTOM FONT FILES ///////////////////////////// // // specifies all the custom (non-system) font files that need to be loaded to service the above described fonts CustomFontFiles { "1" "resource/HALFLIFE2.ttf" "2" "resource/HL2crosshairs.ttf" }

The trick here, is that each of these fonts are loaded via their file names. Adding this to the table is how I changed mine up:

CustomFontFiles { 1 "resource/HALFLIFE2.ttf" 2 "resource/HL2crosshairs.ttf" 3 "resource/crowbar.ttf" 4 "resource/physcannon.ttf" 5 "resource/stunstick.ttf" 6 "resource/pistol.ttf" 7 "resource/357.ttf" 8 "resource/alyxgun.ttf" 9 "resource/smg1.ttf" 10 "resource/ar2.ttf" 11 "resource/shotgun.ttf" 12 "resource/crossbow.ttf" 13 "resource/annabelle.ttf" 14 "resource/frag.ttf" 15 "resource/slam.ttf" 16 "resource/rpg.ttf" 17 "resource/bugbait.ttf" }

The custom fonts will now load, but they won't have a corresponding HUD entry.

Editing the Client Scheme

You'll also need to add one of these for each set of glyphs as well. Around line 278 in the default clientscheme.res file you'll see the following bits:

WeaponIcons { "1" { "name" "HalfLife2" "tall" "64" "tall_hidef" "58" "weight" "0" "antialias" "1" "additive" "1" "custom" "1" } } WeaponIconsSelected { "1" { "name" "HalfLife2" "tall" "64" "tall_hidef" "58" "weight" "0" "antialias" "1" "blur" "5" "scanlines" "2" "additive" "1" "custom" "1" } } WeaponIconsSmall { "1" { "name" "HalfLife2" "tall" "32" "weight" "0" "antialias" "1" "additive" "1" "custom" "1" } }

For the sake of your own time, I'll paste the entire section of code I wrote below.

The Edited Code

I personally recommend adding yours at the very bottom of the block right before where the CustomFontFiles section starts, as it'll make finding the relevant code easier on yourself.

WeaponIconsCrowbar { 1 { name crowbar tall 64 tall_hidef 58 weight 0 antialias 1 additive 1 custom 1 } } WeaponIconsSelectedCrowbar { 1 { name crowbar tall 64 tall_hidef 58 weight 0 antialias 1 blur 5 scanlines 2 additive 1 custom 1 } } WeaponIconsSmallCrowbar { 1 { name crowbar tall 32 weight 0 antialias 1 additive 1 custom 1 } } WeaponIconsPhysCannon { 1 { name physcannon tall 64 tall_hidef 58 weight 0 antialias 1 additive 1 custom 1 } } WeaponIconsSelectedPhysCannon { 1 { name physcannon tall 64 tall_hidef 58 weight 0 antialias 1 blur 5 scanlines 2 additive 1 custom 1 } } WeaponIconsSmallPhysCannon { 1 { name physcannon tall 32 weight 0 antialias 1 additive 1 custom 1 } } WeaponIconsStunstick { 1 { name stunstick tall 64 tall_hidef 58 weight 0 antialias 1 additive 1 custom 1 } } WeaponIconsSelectedStunstick { 1 { name stunstick tall 64 tall_hidef 58 weight 0 antialias 1 blur 5 scanlines 2 additive 1 custom 1 } } WeaponIconsSmallStunstick { 1 { name stunstick tall 32 weight 0 antialias 1 additive 1 custom 1 } } WeaponIconsPistol { 1 { name pistol tall 64 tall_hidef 58 weight 0 antialias 1 additive 1 custom 1 } } WeaponIconsSelectedPistol { 1 { name pistol tall 64 tall_hidef 58 weight 0 antialias 1 blur 5 scanlines 2 additive 1 custom 1 } } WeaponIconsSmallPistol { 1 { name pistol tall 32 weight 0 antialias 1 additive 1 custom 1 } } WeaponIcons357 { 1 { name 357 tall 64 tall_hidef 58 weight 0 antialias 1 additive 1 custom 1 } } WeaponIconsSelected357 { 1 { name 357 tall 64 tall_hidef 58 weight 0 antialias 1 blur 5 scanlines 2 additive 1 custom 1 } } WeaponIconsSmall357 { 1 { name 357 tall 32 weight 0 antialias 1 additive 1 custom 1 } } WeaponIconsAlyxGun { 1 { name alyxgun tall 64 tall_hidef 58 weight 0 antialias 1 additive 1 custom 1 } } WeaponIconsSelectedAlyxGun { 1 { name alyxgun tall 64 tall_hidef 58 weight 0 antialias 1 blur 5 scanlines 2 additive 1 custom 1 } } WeaponIconsSmallAlyxGun { 1 { name alyxgun tall 32 weight 0 antialias 1 additive 1 custom 1 } } WeaponIconsSMG1 { 1 { name smg1 tall 64 tall_hidef 58 weight 0 antialias 1 additive 1 custom 1 } } WeaponIconsSelectedSMG1 { 1 { name smg1 tall 64 tall_hidef 58 weight 0 antialias 1 blur 5 scanlines 2 additive 1 custom 1 } } WeaponIconsSmallSMG1 { 1 { name smg1 tall 32 weight 0 antialias 1 additive 1 custom 1 } } WeaponIconsAR2 { 1 { name ar2 tall 64 tall_hidef 58 weight 0 antialias 1 additive 1 custom 1 } } WeaponIconsSelectedAR2 { 1 { name ar2 tall 64 tall_hidef 58 weight 0 antialias 1 blur 5 scanlines 2 additive 1 custom 1 } } WeaponIconsSmallAR2 { 1 { name ar2 tall 32 weight 0 antialias 1 additive 1 custom 1 } } WeaponIconsShotgun { 1 { name shotgun tall 64 tall_hidef 58 weight 0 antialias 1 additive 1 custom 1 } } WeaponIconsSelectedShotgun { 1 { name shotgun tall 64 tall_hidef 58 weight 0 antialias 1 blur 5 scanlines 2 additive 1 custom 1 } } WeaponIconsSmallShotgun { 1 { name shotgun tall 32 weight 0 antialias 1 additive 1 custom 1 } } WeaponIconsCrossbow { 1 { name crossbow tall 64 tall_hidef 58 weight 0 antialias 1 additive 1 custom 1 } } WeaponIconsSelectedCrossbow { 1 { name crossbow tall 64 tall_hidef 58 weight 0 antialias 1 blur 5 scanlines 2 additive 1 custom 1 } } WeaponIconsSmallCrossbow { 1 { name crossbow tall 32 weight 0 antialias 1 additive 1 custom 1 } } WeaponIconsAnnabelle { 1 { name annabelle tall 64 tall_hidef 58 weight 0 antialias 1 additive 1 custom 1 } } WeaponIconsSelectedAnnabelle { 1 { name annabelle tall 64 tall_hidef 58 weight 0 antialias 1 blur 5 scanlines 2 additive 1 custom 1 } } WeaponIconsSmallAnnabelle { 1 { name annabelle tall 32 weight 0 antialias 1 additive 1 custom 1 } } WeaponIconsFrag { 1 { name frag tall 64 tall_hidef 58 weight 0 antialias 1 additive 1 custom 1 } } WeaponIconsSelectedFrag { 1 { name frag tall 64 tall_hidef 58 weight 0 antialias 1 blur 5 scanlines 2 additive 1 custom 1 } } WeaponIconsSmallFrag { 1 { name frag tall 32 weight 0 antialias 1 additive 1 custom 1 } } WeaponIconsSLAM { 1 { name slam tall 64 tall_hidef 58 weight 0 antialias 1 additive 1 custom 1 } } WeaponIconsSelectedSLAM { 1 { name slam tall 64 tall_hidef 58 weight 0 antialias 1 blur 5 scanlines 2 additive 1 custom 1 } } WeaponIconsSmallSLAM { 1 { name slam tall 32 weight 0 antialias 1 additive 1 custom 1 } } WeaponIconsRPG { 1 { name rpg tall 64 tall_hidef 58 weight 0 antialias 1 additive 1 custom 1 } } WeaponIconsSelectedRPG { 1 { name rpg tall 64 tall_hidef 58 weight 0 antialias 1 blur 5 scanlines 2 additive 1 custom 1 } } WeaponIconsSmallRPG { 1 { name rpg tall 32 weight 0 antialias 1 additive 1 custom 1 } } WeaponIconsBugBait { 1 { name bugbait tall 64 tall_hidef 58 weight 0 antialias 1 additive 1 custom 1 } } WeaponIconsSelectedBugBait { 1 { name bugbait tall 64 tall_hidef 58 weight 0 antialias 1 blur 5 scanlines 2 additive 1 custom 1 } } WeaponIconsSmallBugBait { 1 { name bugbait tall 32 weight 0 antialias 1 additive 1 custom 1 } }

If you haven't guessed yet, you'll be better off putting your custom fonts for each weapon inside the custom folder for it. If you guessed they'd be inside custom/weapon_tutorial/resource/* you get a cookie, because you're right.

Caveats of the Resource Editing

However, you'll have to do this for each and every mod's resource files, as mods or other games have different setups. This can be seen when using the HL2 version of the resource files in EP1, EP2, or Lost Coast. As such, you need to make sure you provide the correct versions for the game/mod you're changing.

There's one last step involved in adding custom fonts to your weapons, though. You might recall a whole section of code in the previously edited weapon_shotgun.txt that started with TextureData - this is what we need to edit next.

Open up your hl2/custom/weapon_tutorial/scripts/weapon_shotgun.txt file, and scroll down to the following:

"weapon" { "font" "WeaponIcons" "character" "b" } "weapon_s" { "font" "WeaponIconsSelected" "character" "b" } "weapon_small" { "font" "WeaponIconsSmall" "character" "b" }

Replace it with the following HUD entries we just made based on the weapon you're editing. In this case, I'm editing the Shotgun, so I added the Shotgun suffix to the entries.

weapon { font weaponiconsshotgun character b } weapon_s { font weaponiconsselectedshotgun character b } weapon_small { font weaponiconssmallshotgun character b }

Your custom weapon script will now load the entries you previously defined for the custom HUD glyphs. Keep in mind that depending on how the font file was made, you may need to edit the icon entries. This is out of the scope of this tutorial, but if your custom icons are being clipped or cut off, this is why.

Things to Watch For

A good many authors package their own manifest files into their .VPK or loose add-ons for HL2, so you might need to open up their content and remove/adjust their custom scripts to align with this method. How you do that is up to you, as there are many different personal ways people do it. If you follow the basic gist of this tutorial, you'll be able to see the similarities between my method described here, and their own. Learning how to see the similarities between the methods will allow you to easily modify them.

Conclusion

@Чеснок Insane necropost but this is because Valve threw in new smg, crossbow and rpg txts in the hl2_complete vpks that tend to overwrite even stuff in the custom folder

Чеснок 3. des. 2024 kl. 16.47

Crossbow and RPG are the only ones that don't work for me

V92 [skaper] 8. mai 2024 kl. 21.38

@chagas

That's intentional as those are additions to the file, not replacements. Episodic is outside the scope of the tutorial.

Chagas 8. mai 2024 kl. 16.53

Hi, i noticed a minor issue with your mods, and this guide, you forgot to include "exec skill_episodic.cfg" on skill_manifest.cfg. This only affects the Episodes, with Zombine and Antlion Workers having 0 health.

HaikuLambda 22. des. 2022 kl. 2.54

Thanks V92, very cool!
