[1.16.5] Create Library Mod

[FOREVEREALIZE]

Hello!

So I am making 3 mods and there is a lot of repetitive code in between them. I decided that my best choice is to create a Library Mod (yes, in caps) to put all of the repeated code in and then just making my other mods off of that.

So if you want MyModA you need MyModA.jar and MyLib.jar.

The issue with this is that I don't know how to do that. Can anyone point me to a tutorial that explains how to do it. But like, every step (except setting up forge)?

Thanks!

 

BTW: Using 1.16.5-36.2.0

I would assume it is not so different from any other java/gradle project.

In the mods.toml add your main "library" mod as a dependency in your other two mods. Then simply import the library mod package into your two other mods and use whatever you want from it. Because the library mod is listed as a dependency in both your other mods, then you can be sure the user will have the library mod installed as well, because if they don't, Forge will notify them before the game is initialized.

Ok

Thanks!

So I did it but I can run the game without the library.

 

Could I please get an example mods.toml.

Thanks!

Yeah, I did that and it allowed me to play without the library. I want that if you want to play Actual Science you need the Actual Core.

This is my mods.toml:

Post a Git repo of your mod.

It is still WIP

That does not compile because you are not declaring a dependency on your library in your build.gradle.

And how do I do that?

I don't quite get it. Could you please tell me how would I do that or give me an example?

I mean... how did you even get your mod to build with that repository? It doesn't compile, because it's referencing classes that do not exist.

Cuz it's still not referencing the core yet. I have been doing other stuff while I wait on answers.

After fixing the compile errors: You spelled dependencies wrong in your mods.toml.

🤦‍♂️

 

Thanks!
