Preventing stock weapons being given in IDKFA cheat?

[MartinHowe]

Is there any way to prevent stock weapons being given in IDKFA cheat?

I have a mod that defines several weapons; some are new, some replace the stock weapons with functional equivalents based on a flexible base class (so they are not derived from the originals). However, IDKFA gives the stock weapons as well. I have found a way to prevent them being given at all or otherwise spawned:

Code: Select all

// --- DISABLE STOCK WEAPONS ---------------------------------------------------

gameinfo
{
    AddEventHandlers = "DisableStockWeapons"
}

// -----------------------------------------------------------------------------

// --- DISABLE STOCK WEAPONS ---------------------------------------------------

version "4.5"

// --- DEFAULT -----------------------------------------------------------------

Class DisableStockWeapons : EventHandler
{
    // =========================================================================

    override void WorldThingSpawned(WorldEvent e)
    {
        actor thing = e.Thing;
        name cn = thing.GetClassName();
        switch (cn)
        {
            case 'Chainsaw':
            case 'Pistol':
            case 'Shotgun':
            case 'SuperShotgun':
            case 'Chaingun':
            case 'RocketLauncher':
            case 'PlasmaRifle':
            case 'BFG9000':
                thing.Destroy();
                break;
        }
    }

    // =========================================================================
}

// -----------------------------------------------------------------------------

But this is a bit clumsy and it runs for every item spawned; it also would happen even if a stock weapon is explicitly spawned in the console or by a script. Is there a less hacky way to do it and limited to cheat giving?

Does your mod define its own PlayerPawn? If so, you can override the give cheat in it.

Thanks, didn't know about that. Sadly this is a generic mod that wants to be as non-intrusive as possible and overriding player classes is about as intrusive as it gets as there's no way to know what player classes will be in use by users. This is the kind of thing that event handlers were made for but GZDoom does not have a 'reason code' in any of its event handlers AFAICS; that would make event handlers much more useful.

Try this:

Code: Select all

class ReplacementHandler : EventHandler
{
	//===========================================================================
	//
	// Handle swapping out vanilla weapons
	//
	//===========================================================================

	override void PlayerEntered(PlayerEvent e)
	{
		PlayerPawn pmo = players[e.PlayerNumber].mo;
		if (!pmo) return;
		SwapWeapons(pmo);
	}

	override void PlayerRespawned(PlayerEvent e)
	{
		PlayerPawn pmo = players[e.PlayerNumber].mo;
		if (!pmo) return;
		SwapWeapons(pmo);
	}
	
	override void WorldTick(void)
	{
		// I can't think of a better way LOL
		for (int i = 0; i < MAXPLAYERS; i++)
		{
			if (playeringame[i])
			{
				let pmo = players[i].mo;
				if (pmo)
				{
					SwapWeapons(pmo);
				}
			}
		}
	}

	//===========================================================================
	//
	// Give smooth weapons to player
	//
	//===========================================================================

	void SwapWeapons(PlayerPawn pmo)
	{
		if (pmo.FindInventory("Pistol") && pmo.player.ReadyWeapon is "Pistol")
		{
			pmo.TakeInventory("Pistol", 0x7FFFFFFF);
			pmo.GiveInventory("ADDYOURPISTOLHERE", 1);
			pmo.TakeInventory("Clip", 20);
		}

		if (pmo.FindInventory("Fist") && pmo.player.ReadyWeapon is "Fist")
		{
			pmo.TakeInventory("Fist", 0x7FFFFFFF);
			pmo.GiveInventory("ADDYOURFISTHERE", 1);
		} // just do this for every weapon lol, so when a stock weapon is cheated, it immediately gets taken.
	}

	//===========================================================================
	//
	// Replace spawned weapons in the world
	//
	//===========================================================================

	override void CheckReplacement(ReplaceEvent e)
	{
		if (e.Replacee == "Fist") e.Replacement = "ADDYOURFIST";
		else if (e.Replacee == "Chainsaw") e.Replacement = "ADDYOURCSAW"
		else if (e.Replacee == "Pistol") e.Replacement = "ADDYOURPISTOL";
		else if (e.Replacee == "Shotgun") e.Replacement = "ADDYOURSHOTGUN";
		
		else if (e.Replacee == "Chaingun") e.Replacement = "ADDYOURCGUN";
		else if (e.Replacee == "BFG9000") e.Replacement = "ADDYOURBFG";
		
		else if (e.Replacee == "RocketLauncher") e.Replacement = "ADDYOURRLAUNCHER";
		else if (e.Replacee == "PlasmaRifle") e.Replacement = "ADDYOURPGUN";
		else if (e.Replacee == "BFG9000") e.Replacement = "ADDYOURBFG";
	}
}

That's originally Nash's code, not mine. I used it in an unreleased project of mine and then re-generalized it for you. That last part handles spawns in world, which also means summon weapname, due to how GZDoom works, while the SwapWeapons() function handles giving through cheats or any instance where a stock weapon would enter the inventory.
