@diabl0:
I suggest before getting your hands seriously dirty with the amount of scripting this would require, you go look into some scripting tutorials first.
Go to the FPSC Chat board and find the "Official FPSC Community Guide" or something like that, lol. It's a sticky topic. Download that document and start learning all that you can about scripting. You'll need every last ounce of that knowledge. Just, don't be put off by how large the document is, lol. It's very big, but you won't be reading all of it at once. Just start with the tutorials and you'll be fine.
Back onto how this could be done:
Using Ply's Mod V1.07a, there's a command called "plrdmgmult" which will set the player's damage multiplier. This could be used for increasing how much damage the player puts out. For "defense", you could make a script similar to the Armor script I created, just have it find how much damage the player took, do some calculations on that amount, give the player their health back and then take away how much they SHOULD have taken.
The one and only,
Whosoever says, "Don't sweat the small stuff," is obviously not a programmer.
