In your Forge Source look in net.minecraft.item#Food, and #Foods. You make the food item, and use a builder.

Check and make sure your texture path is indeed: src/main/resources/assets/<modid>/textures/block and not src/main/resources/assets/<modid>/textures/blocks It's a common mistake.

Instead of extending Block, extend OreBlock and, override the getExperience()

Show your blockstates/compressed_diamond_block.json

is there a compressed_diamond_block.png in your textures/blocks directory?

The error says it's missing the model for your block.

No, the recipe does not go in the loot_table. Just the block you want to drop.

You can view what minecraft does but, I'm not familiar with IntelliJ and were to look for it though. There should be a Reference Library you can peruse through for the source code of minecraft.

Same as you did for recipes. Create the package, then add the block you want to drop.

Do you have a loot_table setup for your block in src/main/resources/data/minecraftmod/loot_tables?

What is the model you're trying to generate? A simple tool?

In your development environment, /data/minecraft/tags/blocks add your walls AND what minecraft has in their JSON. I had a similar problem and, this fixed it.

No, it just tells the leaves how far above ground level to generate. I did figure this out. Overriding the leaves, and logs, tag in resources/data/minecraft/tags/blocks solves this issue. Do the same for your logs.

What do you have the RenderType set too?

I have based my custom tree off of the spruce tree but, when I bonemeal it to make it grow, the trunk is only 1 block high (with random 1 more) and, the leaves generate as they should. Just no trunk to the top of the tree. Tree Class Sapling Class
