Before attempting this, backup the original PBO, especially if it is one of the default files.1. Unpack the pbo your pbo program of choice.
2. Open the file config.cpp (If you see the file "config.bin" instead, config is binarized, so you're out of luck)
3. Find the relevant class for the unit you want to edit
4. Find the
weapons[],
magazines[],
respawnWeapons[] and
respawnMagazines[] sections, and edit them accordingly, for example, if you wanted to swap a soldier with an AK74 to have an M4A1, change this:
CODE
weapons[] = {"AK_74","Throw","Put","ItemMap","ItemCompass","ItemWatch","ItemRadio"};
magazines[] = {"30Rnd_545x39_AK","30Rnd_545x39_AK","30Rnd_545x39_AK","30Rnd_545x39_AK","30Rnd_545x39_AK","30Rnd_545x39_AK","HandGrenade_East","HandGrenade_East"};
respawnWeapons[] = {"AK_74","Throw","Put","ItemMap","ItemCompass","ItemWatch","ItemRadio"};
respawnMagazines[] = {"30Rnd_545x39_AK","30Rnd_545x39_AK","30Rnd_545x39_AK","30Rnd_545x39_AK","HandGrenade_East"};
into this:
CODE
weapons[] = {"M4A1","Throw","Put","ItemMap","ItemCompass","ItemWatch","ItemRadio"};
magazines[] = {"30Rnd_556x45_Stanag","30Rnd_556x45_Stanag","30Rnd_556x45_Stanag","30Rnd_556x45_Stanag","30Rnd_556x45_Stanag","30Rnd_556x45_Stanag","HandGrenade_East","HandGrenade_East"};
respawnWeapons[] = {"M4A1","Throw","Put","ItemMap","ItemCompass","ItemWatch","ItemRadio"};
respawnMagazines[] = {"30Rnd_556x45_Stanag","30Rnd_556x45_Stanag","30Rnd_556x45_Stanag","30Rnd_556x45_Stanag","HandGrenade_East"};
5. Repack the PBO.
6. ???
7. Profit!
This is the way of doing exactly as you've asked, but I'd recommend instead using a replacement mod. Especially if you're planning on editing any of the vanilla units. Unfortunately I'm not too sure how you'd go about doing that.
