After much thought I had decided to start modding in minecraft. I looked through the ForgeDocs on registering blocks and it required me to use AbstractBlock.Properties.of etcetera. However, on trying to type this, there was no such thing and it only came up with AbstractGlassBlock or AbstractfFurnaceBlock and others. Any help would be appreciated in trying to register blocks into the game using 1.17. Kindest Regards,
Russell.
