I want to change how ore blocks work. I know I need to do something along the lines of creating my own block stuff with the same name, but I don't know all the details. what parts need to have the same name as the blocks I want to change? Class name, registry name, block states, etc.?

I tried setting the registry name in a block class via setRegistryName("coal_ore");. that didn't do it. I tried setting all kinds of things to the same name as "coal_ore".

Registry names come in two parts.

You supplied half.

Forge automatically supplied the other half, which was wrong for what you're trying to do.

how do I supply the other half or otherwise do what needs to be done?

Thank you, that worked!

I often do figure things out on my own, but I'm new to java and this is the first time I've done anything with forge. I find it difficult to understand how to work with new code, especially when there is so much of it. I've never worked with anything more complex than a simple swing program.

We're not java school. If you want to learn java, that's fine, just don't do it here.
