Hello, and today we will develop a plugin that modifies the inner game aspects for gameplay, also known as a gamemode.

With our gamemode, we will make one where you spawn as Pyro, and you get only one weapon.

Requirements:
-Sourcemod
-TF2
-TF2Items
-TF2Items GiveWeapon (plugin and .inc)

Now lets get started!

Includes (can be modified):

#include <sourcemod>
#include <tf2items>
#include <tf2_stocks>
#include <tf2items_giveweapon>

You need these for your plugin to compile correctly.

Now, to make our plugin.

new TF2ItemSlot = 8;

This tells us to find all the slots. We need this so that we can strip all the items.

public Plugin:myinfo =
{
	name = "[TF2] Pyro Battle",
	author = "Me",
	description = "A gamemode where pyros fight eachother.",
	version = "1.0",
	url = ""
};

Plugin info, nothing new here.

Next you would need to hook the events, for this, I chose player_spawn and post_inventory_application.

public OnPluginStart()
{
	HookEvent( "post_inventory_application", OnPostInventoryApplicationAndPlayerSpawn );
	HookEvent( "player_spawn", OnPostInventoryApplicationAndPlayerSpawn );
}

Next, add the OnPostInventoryApplicationAndPlayerSpawn function.

public OnPostInventoryApplicationAndPlayerSpawn( Handle:hEvent, const String:strEventName[], bool:bDontBroadcast )
{
}

Next, add the client defines in the extention:

new iClient = GetClientOfUserId( GetEventInt( hEvent, "userid" ) )

After that, add the part where it removes all of the players items before spawning.

for( new iSlot = 0; iSlot < _:TF2ItemSlot; iSlot++ )
		TF2_RemoveWeaponSlot( iClient, iSlot );

Next, add the weapon. we will talk about the weapon code later.

TF2Items_GiveWeapon(iClient, 9990);

Then add the slot1 and slot2 removers, just in case.

TF2_RemoveWeaponSlot(iClient, 1);
TF2_RemoveWeaponSlot(iClient, 2);

Then add the SetClass, and then you are done.

TF2_SetPlayerClass(iClient, TFClass_Pyro, false, true);

So the entire plugin should look like this:

#include <sourcemod>
#include <tf2items>
#include <tf2_stocks>
#include <tf2items_giveweapon>

new TF2ItemSlot = 8;
 
public Plugin:myinfo =
{
	name = "[TF2] Pyro Battle",
	author = "Me",
	description = "A gamemode where pyros fight eachother.",
	version = "1.0",
	url = ""
};
 
public OnPluginStart()
{
	HookEvent( "post_inventory_application", OnPostInventoryApplicationAndPlayerSpawn );
	HookEvent( "player_spawn", OnPostInventoryApplicationAndPlayerSpawn );
}

public OnPostInventoryApplicationAndPlayerSpawn( Handle:hEvent, const String:strEventName[], bool:bDontBroadcast )
{
	new iClient = GetClientOfUserId( GetEventInt( hEvent, "userid" ) )
	
	for( new iSlot = 0; iSlot < _:TF2ItemSlot; iSlot++ )
		TF2_RemoveWeaponSlot( iClient, iSlot );
	
	TF2Items_GiveWeapon(iClient, 9990);
		
	TF2_RemoveWeaponSlot(iClient, 1);
	TF2_RemoveWeaponSlot(iClient, 2);
	
	TF2_SetPlayerClass(iClient, TFClass_Pyro, false, true)
}

Now, here's the weapon code, create a file named tf2items.givecustom.txt in sourcemod/configs, then put this in the .txt:

"custom_give_weapons_vlolz"
{
	"9990"
    {
		"classname"	"tf_weapon_syringegun_medic"
		"index"		"527"
		"slot"		"0"
		"quality"		"9"
		"level"		"10"
		"attribs"		"280 ; 1 ; 6 ; 1.45 ; 31 ; 3 ; 32 ; 1 ; 2 ; 1.4 ; 125 ; -10"
		"ammo"		"300"
    }
}

Then you are done!

You can edit this plugin to your liking, but DO NOT RELEASE THE PYROBATTLE PLUGIN TO NEW PLUGINS.

Plugin and files included are below.
