In half life based games, a portion of the game behaviour related to game rules and events is grouped in objects derived from an object named CGameRules. I've collected virtual functions of it (mod dependent and not) so you can use them out of the box after installing this pack.

A mandatory step of using those functions is retrieving the CGameRules derived object itself.

Code: Select all

#include <amxmodx>
#include <orpheu>
#include <orpheu_stocks>

new g_pGameRules

public plugin_precache()
{
    OrpheuRegisterHook(OrpheuGetFunction("InstallGameRules"),"OnInstallGameRules",OrpheuHookPost)
}
public OnInstallGameRules()
{
    g_pGameRules = OrpheuGetReturn() 
}

This hooks the function InstallGameRules that exist on every mod and that creates the object we need. After this, our variable g_pGameRules will contain a reference to the object so we can after that hook and call functions of it. As a side note in TFC the function is a little bit different so I had to named it InstallGameRules_tfc. Take that into account if you are making a plugin that should work in TFC.

Now, hooking a function:
Example GetNextBestWeapon(CBasePlayer *, CBasePlayerItem *)

Code: Select all

public plugin_init()
{
/* GetNextBestWeapon is the name of the function. You can see the name of the function at configs\orpheu\virtualFunctions\CGameRules   
    CGameRules is the base object and is to be used in every function in the package
    OnGetNextBestWeapon is the name of our hook function
*/
  OrpheuRegisterHookFromObject(g_pGameRules,"GetNextBestWeapon","CGameRules","OnGetNextBestWeapon")
}

public OnGetNextBestWeapon(gameRules,playerID,weaponID)
{
    // Game rules object is always passed as the first argument but we don't need it since we already have it in g_pGameRules
}

Now, to call a function:
Example: CanHaveAmmo(CBasePlayer *, char const *, int)

Code: Select all

new OrpheuFunction:CanHaveAmmo = OrpheuGetFunctionFromObject(g_pGameRules,"CanHaveAmmo","CGameRules")
    
// When you call any of those functions you have to pass g_pGameRules always as the first argument 
new result = OrpheuCall(CanHaveAmmo,g_pGameRules,id,"ammo_buckshot",30)

If it sounds complicated or whatever, tell me.

After installing the package the functions will be at "configs\orpheu\virtualFunctions\CGameRul es". Check that folder and each file to know the arguments for each function and in which mod it works.

Last note: this ended up extensive so I probably made more than one error. If a function doesn't work for you, tell me its name, the mod and the operative system. Bye.

Where can you find the source of these functions?

EDIT:

Nevermind.

multiplay_gamerules.cpp

Posted: **Sun Sep 13, 2026 6:51 am**

It would be nice if someone could filter properly the functions available by game. Right now all is mixed and it's a pain to find something you can use.

There're 3 objects.

The last two inherites methods from CGameRules

Here's wha't I found in CS

Don't know if CHalfLifeMultiplay and CHalfLifeRules can be referenced from CGameRules. I guess not.

CGameRules is the parent base class that CHalfLifeRules and CHalfLifeGamePlay derive from. In a single player game you have a CHalfLifeRules object, in a multiplayer you have a CHalfLifeMultiplay (Arkshine correct me if I'm wrong ).

This thread is about virtual functions of CGameRules

Anyway, you can use any of those functions with signatures but, this is for virtual functions to make it easy to address them (by providing only an offset)

Posted: **Sun Sep 13, 2026 6:53 am**

for someone to find available functions in each mod.

So in CS theres only 4 used?
Code: Select all
CGameRules::CanHaveAmmo(CBasePlayer *,char const *,int)
CGameRules::CanHavePlayerItem(CBasePlayer *,CBasePlayerItem *)
CGameRules::GetPlayerSpawnSpot(CBasePlayer *)
CGameRules::RefreshSkillData(void)

Right, I understand now (I think).

For example, GiveC4 it's a virtual function of gamerules and, in case of HalfLifeMultiPlay, it's handled there.

That's why I can't see inside cs_i386.so any CGameRules::GiveC4.

I'm correct?

A virtual function is a function that can be overrided by another in a derived class. In this case GiveC4 seems to be a virtual function belonging to CHalfLifeMultiplay and not from CGameRules. So, the files aren't quite correct.
