Hello Everyone,

I am new to the modding scene and just getting started with endless space 2. I am trying to make a new faction affinity that I am adding in via a trait. The trait is a dynamically increased value for science and industry to empire both starting at 25%. After 5 turns the value of increased science increases to 50%, but industry falls to 0%. Over the next 10 turns the two values swap again. this continues throughout the game. See below where y(blue) is the value of science, and y(red) is industry. X would be the value "CurrentTurn".

My question is: Is it possible to add a function in to determine a value. Pi I can substitute for 3.14... and it should hold true for about 500 turns as long as enough decimals are present but I would still need to use sine. 

Any help or another approach on how to do this would be much appreciated.

For Sine you may be able to use Sin(Angle) in the XML in the same way Floor(Decimal) is used as they are both .Net Framework Math Methods

Maybe even PI but it’s a Class/Field so I’m not so sure about that one.

Thanks! I'll give it a try and see what happens.

Everything now successfully loads in to a Mod but the game freezes uponlaunching in to a game. Im not sure where I went wrong. Here is the work:

The best way to find out what's going wrong is by looking at the diagnostic file you can find them in "Documents/Endless Space 2/Temporary Files"

If your still not sure on what's going wrong, upload the diagnostic file here and I'll have a look.

Thank you, I didn't even know this exsisted. That is very helpful. The error is with the sine operation. Im guessing this means Im stuck.

The following exception was raised: System.InvalidOperationException: There is an error in XML document. ---> System.InvalidOperationException: 'Sine' is not a valid value for Amplitude.Unity.Simulation.SimulationModifierDescriptor+ModifierOperation.

I dont know enough about the language or allowances for endless space 2 to really know if there is another way around.

I can think of another way to have a similar effect such as each change being 5% each turn, 

This all works off the CurrentTurn Property in SimulationDescriptors[Empire].xml much like your original plan.

first you will want to make 2 new properties CurrentTurn20, CurrentTurn10, Clock10

For CurrentTurn10 take $CurrentTurn divide by 10 then floor the value - It should start at 0 and increase by 1 every 10 turns

For CurrentTurn20 take $CurrentTurn divide by 20 then floor the value then multiply by 2 - It should start at 0 and increase by 2 every 20 turns

$Clock10 should be set as 1 + ($CurrentTurn - ($CurrentTurn10*10) It should go in a loop of 1,2,3,4,5,6,7,8,9,10

The Science boost would be set by:  5* (10 - ( $Clock10 *  ( 1 + ($CurrentTurn20-$CurrentTurn10)) ))

The Industry boost would be set by: 5* ( $Clock10 *  ( 1 + ($CurrentTurn20-$CurrentTurn10)) )

This is just a rough idea of how it could be done, I expect it will need a lot of tweaking to actually work.
