Modding Weapons (Ammo, Weight etc) tutorial - Half-Life

[page=Introduction]
Okay Just click on a chapter/Subject you want to Change
also you are working in the weapon.h the whole tutorial
[page=Weapon Capacities]
open weapons.h and go to line 108

There you will see:

// weapon clip/carry ammo capacities
#define URANIUM_MAX_CARRY 100
#define _9MM_MAX_CARRY 200
#define _357_MAX_CARRY 36
#define BUCKSHOT_MAX_CARRY 125
#define BOLT_MAX_CARRY 50
#define ROCKET_MAX_CARRY 5
#define HANDGRENADE_MAX_CARRY 10
#define SATCHEL_MAX_CARRY 5
#define TRIPMINE_MAX_CARRY 5
#define SNARK_MAX_CARRY 15
#define HORNET_MAX_CARRY 100
#define M203_GRENADE_MAX_CARRY 10

**Remember, This is how much you can carry on you at a time for a reload. lets say you get a glock 7/200 <<< thats the number your changing

[page=Weight Factors(how fast you run with weapon etc)]

Okay, Line 92, search it... in the Weapon.h.

now you should see this...

// weapon weight factors (for auto-switching)   (-1 = noswitch)
#define CROWBAR_WEIGHT		0
#define GLOCK_WEIGHT		10
#define PYTHON_WEIGHT		15
#define MP5_WEIGHT			15
#define SHOTGUN_WEIGHT		15
#define CROSSBOW_WEIGHT		10
#define RPG_WEIGHT			20
#define GAUSS_WEIGHT		20
#define EGON_WEIGHT			20
#define HORNETGUN_WEIGHT	10
#define HANDGRENADE_WEIGHT	5
#define SNARK_WEIGHT		5
#define SATCHEL_WEIGHT		-10
#define TRIPMINE_WEIGHT		-10

Explanation: 0 = Normal Speed of running, the higher it gets the slower the player runs... if you go below zero -10 for say, you run faster then normal... So change it on your accord. 20 is the heaviest in this case.

[page=Ammo in a Clip]
This is abit easy all the Value changes are under each other heres the next one

// the maximum amount of ammo each weapon's clip can hold
#define WEAPON_NOCLIP			-1

//#define CROWBAR_MAX_CLIP		WEAPON_NOCLIP
#define GLOCK_MAX_CLIP			17
#define PYTHON_MAX_CLIP			6
#define MP5_MAX_CLIP			50
#define MP5_DEFAULT_AMMO		25
#define SHOTGUN_MAX_CLIP		8
#define CROSSBOW_MAX_CLIP		5
#define RPG_MAX_CLIP			1
#define GAUSS_MAX_CLIP			WEAPON_NOCLIP
#define EGON_MAX_CLIP			WEAPON_NOCLIP
#define HORNETGUN_MAX_CLIP		WEAPON_NOCLIP
#define HANDGRENADE_MAX_CLIP	WEAPON_NOCLIP
#define SATCHEL_MAX_CLIP		WEAPON_NOCLIP
#define TRIPMINE_MAX_CLIP		WEAPON_NOCLIP
#define SNARK_MAX_CLIP			WEAPON_NOCLIP

Okay well simply Change the Glock to like a 7 so now it has 7 bullets per clip :P so change the number, unless you want it to have no clip there for you would use the Value WEAPON_NOCLIP

[page=Ammo in gun at pickup]

// the default amount of ammo that comes with each gun when it spawns
#define GLOCK_DEFAULT_GIVE			17
#define PYTHON_DEFAULT_GIVE			6
#define MP5_DEFAULT_GIVE			25
#define MP5_DEFAULT_AMMO			25
#define MP5_M203_DEFAULT_GIVE		0
#define SHOTGUN_DEFAULT_GIVE		12
#define CROSSBOW_DEFAULT_GIVE		5
#define RPG_DEFAULT_GIVE			1
#define GAUSS_DEFAULT_GIVE			20
#define EGON_DEFAULT_GIVE			20
#define HANDGRENADE_DEFAULT_GIVE	5
#define SATCHEL_DEFAULT_GIVE		1
#define TRIPMINE_DEFAULT_GIVE		1
#define SNARK_DEFAULT_GIVE			5
#define HIVEHAND_DEFAULT_GIVE		8

okay this is the next line, this just shows or repersents how much ammo is given with the gun when you first pick it up. this can be changed, by simply changing the numbers.

[page=Ammo Box Pick ups]

// The amount of ammo given to a player by an ammo item.
#define AMMO_URANIUMBOX_GIVE	20
#define AMMO_GLOCKCLIP_GIVE		GLOCK_MAX_CLIP
#define AMMO_357BOX_GIVE		PYTHON_MAX_CLIP
#define AMMO_MP5CLIP_GIVE		MP5_MAX_CLIP
#define AMMO_CHAINBOX_GIVE		200
#define AMMO_M203BOX_GIVE		2
#define AMMO_BUCKSHOTBOX_GIVE	12
#define AMMO_CROSSBOWCLIP_GIVE	CROSSBOW_MAX_CLIP
#define AMMO_RPGCLIP_GIVE		RPG_MAX_CLIP
#define AMMO_URANIUMBOX_GIVE	20
#define AMMO_SNARKBOX_GIVE		5

Okay this is the last one. but it speaks for itself, you pick up bullets or a box of bullets and it adds the amount that you have typed in here

[page=Disabling Weapons you dont want used]
Okay this is a quick explanation how you can stop a weapon from being used. ill use some codes from here and ill disable the RPG ill do them in according chapter order to!

//First line to edit to disable weapon
//default is 5 im changing it to 0
#define ROCKET_MAX_CARRY 0  

heres a little punishment for those people who use amx and make the rocket accesible

#define RPG_WEIGHT			90

that i just defined is practically, well not moving

and the last code to change...

#define RPG_MAX_CLIP			1 

change to

#define RPG_MAX_CLIP			0

Now your done when they get the weapon it will show up
but they cannot pull it out or use it. and if amx modders get by that. they have to worry about weight issues, you wont be able to walk. but thats something i pulled on my friend, he tried to fix the rpg weight for days, then i told him :D

ANYWAYS HOPE YOU ENJOYED IT its easy as hell a newb could understand this.
