And the function setBlockHarvestLevel appears not to work:

 

GameRegistry.registerBlock(BlockCop);

MinecraftForge.setBlockHarvestLevel(BlockCop, "Pickaxe", 1);

 

Yet I can mine it with wood...

Use GameRegistry.registerBlock(block, "unique block name") instead

 

This is an example from my mod.

GameRegistry.registerBlock(cobaltBlock, "blockCobalt");

 

Thanks but I can still mine with a wooden pickaxe?

Also, how would you make a block spawn naturally?

Thanks for the help so far

 

It's the Material class setRequiresTool().

It's the Material class setRequiresTool().

 

I've also thought about making a block that requires a tool to harvest, but that method doesn't specify what level of tool is required, only that one is.  How does vanilla minecraft prevent ore blocks from being mined with wooden picks?  I haven't been able to find an example.

 

And what exactly does that "unique block name" in the registerBlock method do?  What does it mean, is it different from setBlockName or LanguageRegistry.addName?
