Do you saw anywhere Helicopters used Wood, Coal, Coke or Wood Stripes for fuel? Can you change it? Or can someone change this mod to use uranium fuel, rocket fuel and so on, or any other fuels from other mods? Is the file heliBase.lua for defining kind of fuels?

Coke?

Are you talking about Krastorio2?

HR, just like everything else that requires fuel, takes

car.energy_source.fuel_categories

You usually don't define a specific fuel (you can imagine that would be a nightmare to maintain... Instead, you apply fuel_categories to vehicle from a mod, for example K2, that's "kr-vehicle-fuel"

Additionally to that, you need to specify the default fuel as well as a ratio that would make sense...

Example how the the fuel category is applied is in data-final-fixes:

https://github.com/wolfhowlmedia/factorio-helicopters/blob/master/data-final-fixes.lua

and calculating ratios are in heliBase:

https://github.com/wolfhowlmedia/factorio-helicopters/blob/master/logic/heliBase.lua

around line 940... But you're actually better off by just seatching for "krastorio" in that file

Thank you brother!! I don't played Krastorio 2 before, but I play with Periodic Madness, and now I know what to do, to play with Periodic Madness fuels. Thanks again and have a nice day!
