Exponential Sliders?


#1

Seeing as policies are done with CSV, I assumed making something affected exponentially would work just fine (since online, it says CSV files can use the ^ function). I am having trouble with it, though, and would like to know: can I make a policy that affects group A at say, x^.75 rate? Or .4^x? Which one would work, if either? Is it just a formatting issue? Because it seems to me that this could unlock a whole bunch of cool policy paths - such as policies that raise a faction’s support for some implementation, but if you take it too far, you lose that support.

Hello everyone,

Please read first:

Ok, how do I start?!
Talking about Policies. They are defined in policies.csv. Each line, starting with ‘#,’ is one policy. (break-line turned off!)
Policies have a white icon on the main screen in the game.
Sliders are for Policies to adjust them freely by the player.

The Slider setting is ‘x’.
Usually x can be set to any position between 0 = 0% = minimum = all the way to the left ,
and 1.0 = 100% = maximum = all the way to the right.

Policies have income(taxes) or cost(others) AND have outputs/effects.

The output/effects have/use functions/formulas.
The outputs use functions. Each effect has a name and a formula.

functions (examples):
-1 to 0 to 1 :: static value
5x or .2x :: linear [math.]
x^2 or x^6 :: power [math.]
x^(1/2) or x^(1/6) :: root [math.] , radical [math.]

Usually all combined:
…,#Effects,“CrimeRate,-0.16*(x^0.4),4”,“ViolentCrimeRate,-0.10-(0.20x),3","Conservatives,0.10+(0.14x)”,
(example sequence from policies.csv)

Usually, each formula gives an effect/output between -100% to -0%
OR +0% to +100% towards the named simulation graph. Simulation graphs / values are defined in simulation.csv
and have a blue icon on the main screen in the game.

The simulation graphs themselves have values between 0 = 0% to 1.0 = 100%, usually.

Working with and adjusting these formulas REQUIRE a scientific caculator, e.g. Windows Calc, scientific view.
Or better a math graph programm, where you put in a formula and it will draw the curve for you, for x=0 to 1.
This shows you how the curve bends (up/down) and for which x-value the resulting y will be 50%, 10%, 90%.


b.t.w. everything needed is already possible.
There is no need for an exponential ‘x’ - in my eyes :wink:
Cheers

use formula
+0.5-1*(x^6)
,“simu-name,0.5-(x^6),1”,

it adds 0.5 / +50% support.
but if you go to x=89% * slider, the support is gone / +0%
if you go even higher, it becomes negative.
at x=100% slider, the support is -0.5 / -50% !

Cheers


  • precisely calculated by inverse function:
    (x^6) = 0.5 —> 0.5^(1/6)=x
