Hey, Need some logical help here.

Lets say I've 2 arrays:

KillerSkill
VictimSkill

and I want to increase KillerSkill, but the increased count should depend on KillerSkill and VictimSkill.
Now if Killer kills Victim:
* The higher KillerSkill is, the lower it increases.
* The lower VictimSkill is, the lower it increases.
* The lower KillerSkill is, the faster it increases.
* The higher VictimSkill is, the faster it increases.

And same method for dieing:
*Should depend on same things, but with decreasing.

So how can it be done with mathematical equation.

Seems most difficult thing I've ever seen

Can't be done in simplier way ?

I don't know nothin' 'bout such stuff, but have you tried:

* Pencil ?
* Paper ?

Hey, I'm just sayin'...!

What do you think if I will do this with factor (coefficient) number ?

I think the simplest way would just be to divide the victim's skill by the killers skill to get a multiplier.

Let's say the victim's skill is 5000, and the killer's skill is 1000. 5000/1000 = 5, so the killer should get 5x the normal number of points.

Alternatively, if the victim's skill is 1000, and the killer's is 5000, 1000/5000 = 0.2, so the killer would get a fifth of the usual points.

If you want the effect to be more/less pronounced, you could use exponentials (e.g. square it to make it have more of an effect, or take the square root to have less of an effect).


EDIT: Now that I think about it, you'd get some pretty funky results whenever one of the skill levels approached zero, and it would completely fall apart if one was negative. Forget I ever said anything

Okay, here's a much better system to find a multiplier.

Take the difference between the victim and the killer's skills. For example, 5000 - 1000 = 4000.

Then take a number slightly larger than one to the power of this difference. For example, 1.0005:

1.0005^(5000 - 1000) = 7.4x the normal number of points
1.0005^(2000 - 1000) = 1.6x
1.0005^(1000 - 1000) = 1x (they have the same skill)
1.0005^(1000 - 2000) = 0.6x (killer is more skilled)

And it works nicely even if one of the players has a negative skill, or zero skill:

1.0005^(5000 - 0) = 12.2x

The only thing is you'll have to do some tweaking to find the optimum value - 1.0005 seems to work well with skills in this range. Hope that helps.

what does this stands for ? 1.005^
