Honestly, i don't know where to ask this question, so i am writing it here.

Did you made an API to allow other mod dev to use some options of in control ? If yes, how to use it in our mods ?

Why do you need an API? Can you describe your usecase?

What I need to do is disable mob spawning in a dimension i made and not in vanilla dimensions

In Control can disable spawning in any dimension. Just specify the dimension in the rule like yourmod:dimensionid

In the rule like ?

Oh. My message was cut off. Fixed

And when i download In Control into the mod folder of /run in my ide, i can't start any worlds and Minecraft crashes. So, how should i do to use In Control while creating my mod ?

Why do you need it during dev? Anyway. You can include In Control through a proper maven dependency in your build.gradle (using the curse maven). See how I do this for The One Probe: https://github.com/McJty/TutorialV3/blob/main/build.gradle#L139

Ok, thank you for your help, but how do I get this curse.maven:the-one-probe-245211:3550084 but for In Control ?

Go to the incontrol curseforge page. The first number is the id of the project. The second number the id of the file you want (the specific version you want to use)

Ok, i understand now, thank you for your help, and have a great day !
