Creating A HL2 Multiplayer Weapon

Ok so let's get this straight, you're wanting to create a Whole NEW weapon for your new Half Life 2 Multiplayer game right? Now your stuck and need a little tutorial which will tell you what to do right? Well luck is here as i shall teach you how to impliment a new weapon ready to use for your multiplayer game =D

weapon_357.cpp

Ok so what i first of like to do is open up weapon_357.cpp on the server side, and once that's open i hit CTRL + H which brings up the Replace box/tab (depending on how you have it) now what i first of all do is this

Replace all instances of CWeapon357 with CWeaponRifle In total i get a result of 15 replaced accurances which seem's good to me but you might think thats it right?

WRONG!

Look for where ever the Weapon357 is replace it with WeaponRifle becareful, C++ syntax is very case sensitive Once you've got that done move on to the next part =D

weapon_rifle.cpp

Ok, this is main part so be very careful here ok? Follow exactly what i do. Hit CTRL A + CTRL C now in your solution just where your 357 is located, right click the Weapons folder then select Add> Add New Item. Now select CPP in the name part add weapon_rifle.cpp MAKE sure you change the save location down the bottom to [mod dir]\src\game_shared\hl2mp as it is a common file between the server and client. Now click ok and it will be created and in there ready and 2003 edition is what i use, open's the new file up for you straight away. NOW in the weapon_rifle.cpp hit CTRL + V hit save (ctrl + s) now don't be silly and go save the 357 file just hit CTRL + Z until the instanes are all the same, or just close it and if it ask's you to save say No Wow, we're getting somewhere now aint we =D.

Now to add the same file to the client side, open up the client/Source Files/hl2mp/weapons and right click on the folder and select add existing. Select the same file weapon_rifle.cpp that is in the game_share dir (from before) and click add. Compile and your done.

weapon_rifle.TXT

Ok so now your probabley happy and dandy that theres no errors right? WELL YOU SHOULD BE! that's probabley the hardest part over and done with in my opinion. Right so let's get the weapon in game now shall we? open up weapon_357.txt which is located in MyMod/Scripts/weapon_357.txt. Copy it all, and paste it into a new notepad document edit what you like in here here's mine for this tutorial :)
