I tried overriding one of the vanilla rock blocks according to instructions in this old thread, but failed for the same reason the org TM did, even though I got a tiny bit farther than he did.
I can remove the original block entirely from world spawn, and replace it with custom version, which I want to prevent due to following up workload(adapting recipes etc. to custom block).
What I tried solving the issue/actually making replacing(partially) work:
1. I had to use the original Forge variant of registering the block in main class, like that:
which actually did use the custom granite block as replacer(not exactly illustrated in the old thread), but didn't consider it on world feature generation...
2. I then believed it was due to not using correct path variables for assets texture/models/blockstates etc., so I created missing asset packets for both, vanilla asset path, and my mod path. This also did not fix the issue with creating holes filled up with Items.AIR on world feature generation.
3. I then tried to remove the vanilla granite block during feature generation, and reimported it after with my replacement set up, during feature generation as well(according to @Luis_ST advice). But the holes were still there, only this time I got my replaced granite block spawned as well.
What do I want to achieve(asking myself and you in hope maybe there's a better solution)?
Mojang found it a good idea, to give one of the hardest rock materials on this planet, the .harvestLevel(soft as a pillow), so I can harvest it with a wooden pickaxes(which technically is even worth, but doesn't matter since wooden "pickaxe" tools do not exist in my mod). I really just want to compare harvestLevel of any of my tools, against the harvestLevel of the targetBlock, so I can automatically disallow harvesting it, if the tool doesn't match the harvestLevel(which for whatever reason does not work as intended in 1.16.5 Minecraft).
Edit: and before you shout "doPlayerHarvestCheck". Yes, I do that!
Edit2: Also, why are there Manga Comic Girls, on the right upper corner of my Monitor, stating how can it be that big?(whatever "it" is?)
I have this error when using forge (with mods or without) and have tried the official minecraft solution but it does not work, I am using the latest version for 1.18 and the official minecraft launcher
