Lanterns Belong on Walls

Adding support for lanterns is a straightforward process.

1. Add the Gradle dependency:

   repositories {
       //...
       maven {
           name = "Modrinth"
           url = "https://api.modrinth.com/maven"
       }
   }
   
   dependencies {
       //...
       modImplementation "maven.modrinth:lanterns-bow:${lanterns_bow_version}"
   }
   

   Refer to the versions page for the most recent version.
   Read about the Modrinth Maven here.
2. Create an entrypoint class:

   public class ExampleLanternModWall implements WallLanternsEntrypoint {
       @Override
       public void patchLanterns() {
           this.addLantern(new Identifier("example_mod", "example_lantern"));
       }
   }
   

3. Add the entrypoint to your fabric.mod.json:

   ...
   "entrypoints": {
       ...
       "walllanterns": "com.example.mod.examplemod.ExampleLanternModWall"
   }
   

4. Add the proper blockstates and models to your mod. Take a look here for a general idea of what it should look like.
   The only major difference is that your blockstate file will need to include variants that have the facing property and variants that lack it. This will help to ensure compatibility when Lanterns Belong on Walls is not installed.
