Adding your file to solution

Open your "everything.sln". In the solution explorer find "Server (HL2)" then "Source Files" and "HL2 DLL"

Right click on "HL2 DLL" -> "Add" -> "Existing File" and chose "weapon_<your weapon name>.cpp"

Editing weapon_<your weapon name>.cpp - pistols

Adding your weapon to game

Implementing your weapon to c_weapon__stubs_hl2.cpp

Open "c_weapon__stubs_hl2.cpp" and find

STUB_WEAPON_CLASS( weapon_pistol, WeaponPistol, C_BaseHLCombatWeapon );

Copy this line and paste beneath, change "weapon_pistol" to "weapon_yourweaponname" and "WeaponPistol" to "WeaponYourWeaponname", example:

Now compile it!

weapon_<your weapon name>.txt

Creating "weapon_<your weapon name>.txt"

Go to your mod's folder (inside sourcemods) and find scripts folder. Create .txt file called weapon_<your weapon name>.txt", open it and paste following code to it:

// Glock18 WeaponData { // Weapon data is loaded by both the Game and Client DLLs. "printname" "#HL2_Glock18" "viewmodel" "models/weapons/v_pist_glock18.mdl" "playermodel" "models/weapons/w_pist_glock18.mdl" "anim_prefix" "glock18" "bucket" "2" "bucket_position" "0" "bucket_360" "0" "bucket_position_360" "0" "clip_size" "18" "primary_ammo" "Pistol" "secondary_ammo" "None" "weight" "2" "rumble" "1" "item_flags" "0" // Sounds for the weapon. There is a max of 16 sounds per category (i.e. max 16 "single_shot" sounds) SoundData { "reload" "Weapon_Pistol.Reload" "reload_npc" "Weapon_Pistol.NPC_Reload" "empty" "Weapon_Pistol.Empty" "single_shot" "Weapon_Glock.Single" "single_shot_npc" "Weapon_Glock.Single" "special1" "Weapon_Pistol.Special1" "special2" "Weapon_Pistol.Special2" "burst" "Weapon_Pistol.Burst" } // Weapon Sprite data is loaded by the Client DLL. TextureData { "weapon" { "font" "WeaponIcons" "character" "d" } "weapon_s" { "font" "WeaponIconsSelected" "character" "d" } "weapon_small" { "font" "WeaponIconsSmall" "character" "d" } "ammo" { "font" "WeaponIconsSmall" "character" "p" } "crosshair" { "font" "Crosshairs" "character" "Q" } "autoaim" { "file" "sprites/crosshairs" "x" "0" "y" "48" "width" "24" "height" "24" } } }

Change all "Glock18" to "your weapon name", change models to your weapon's models. Do the same to sounds.

Accesing your weapon in game

Open console and type:
"give weapon_<weapon name>"

Thats all :3

Works nicely, until I attempt to actually use the weapon. It does not fire a Bullet, no impact decal is made on any wall, and no blood is left from a player. (Yes the weapon_script.txt is set up right, and includes damage). The firing animation of my model, as well as the sounds play, and it consumes ammo, but won't actually fire and hit anything.

My code in c_weapon__stubs_hl2.cpp looks nearly identical to yours, however, for some reason I keep getting the error:
] give weapon_testweapon
Attempted to create unknown entity type weapon_testweapon!
NULL Ent in GiveNamedItem!
Is there anything else that could be causing this issue?
