Grenade/explosive damage fading

[Victor]

It seems a bit backwards, but it's explained like this:

endrange = range + startrange
fade amount = reduction in damage

endrange is used to describe "range", which is the fading factor
fade amount is left to describe the cut-off

On second thought, I'll use your method. Instead of cutting off by damage, we can use distance.

I need you to fix the values (RPG and grenade) now.
endrange = cutoff distance
rangeminus = fading factor

Also, I wonder why we need to have damage in the denominator as well.
