I have recently got back into modding after 6 months hiatus. Little to say I am quite stumped on how to register blocks and of the sort since GameRegistry.register is now a private method. I can't seem to figure out how to do this.

Forge's documentation explains this here.

 

For examples, look at some of my mod's init classes.

Edit: after looking through your code, I still don't understand where you register blocks; I registered the event with the MinecraftForge.eventBus, but I get the following error:

 I am probably just being a noob but I cannot make sense of how to do it.

 

Finally, makes sense. Thank you!

Ya ^

I register my Blocks in the ModBlocks.RegistrationHandler class.

 

Which version of Forge are you using? Post your code.

Ya, sorry, I understand where you register the blocks, but where do you call the class that registers the blocks?

I don't call it from anywhere, the @Mod.EventBusSubscriber annotation automatically subscribes it to the Forge event bus in the mod construction phase.

My project: https://github.com/dannowilby/Argh

What is your question?

I get an error, which I posted above, and have no knowledge on how to remedy it.

What version of forge are you using? Did you install it correctly?

I'm using version 1.11.2-13.20.0.2228 and I have installed it properly.

Still have no idea

Try to update your mappings

@Dylem

What do you mean?

search on internet on how to update your mappings with forge

I still get the error.

I'll repost the error log just incase there is a small change, but I believe it is the same.

net.minecraftforge.registries.IForgeRegistryEntry only exists in Forge 1.12-14.21.0.2348 and later (with the overhaul of the registry system), before that it was net.minecraftforge.fml.common.registry.IForgeRegistryEntry. I'm not sure why your IDE let you compile and run your project while referencing a class that doesn't exist.

 

Update to the latest version of Forge.

Edited June 26, 20178 yr by Choonster

@Choonster It still does not work. I clean installed Forge 1.12-14.21.0.2373 but I still get the same error.

Any solutions?

I'm not sure why it's not working, that class definitely exists.

 

All I can suggest is deleting the Gradle cache with the cleanCache task, deleting the build directory with the clean task and deleting your IDE project with the cleanEclipse/cleanIdea task before setting up the project again by following these instructions exactly.
