[1.12.2] Adding properties from one block to a modified version

[Elrol_Arrowsend]

I am trying to make vanilla blocks unbreakable, I have tried doing this in 3 ways, only one of which was successful. 

The ways that I have tried have been doing this are 
1) Getting a list of all the properties on a block, then cycling through the list, and setting the value to the new block state. This returns an error with the IBlockState#withProperty(); method where it says the arguments are wrong.

IBlockState newState = block.getDefaultState();
	existingState.getProperties().forEach((key, value) -> {
	newState.withProperty(key, value);
});

 

2) I have tried adding my own PropertyBool to keep track of blocks that are unbreakable, and have a structure apply them to the blocks that it places. This however throws an error because the BlockStateContainer does not have them already added to it. 

 

Both of these things led to me returning to what I started with, and just make custom blocks, pointing to Minecraft models so that they look identical to the vanilla counterparts and adding resistance and making them unbreakable. Which is the only thing that worked, And I just think that there should be a way to accomplish what I am seeking to achieve without doubling all the blocks in Minecraft.

 

If anyone is able to help out with this small issue that would be wonderful, I look forward to hearing from you in the morning.

couldn't you iterate through the block registry in the registry event (after all other mods have run) and call Block#setUnbreakable on each entry?

Well, I don't want all vanilla blocks to be unbreakable, just ones that I have generated by my multiblocks (so that players cant break the walls and skip to the end of the dungeon)

Alright well since I have some framework set up to make vanilla blocks easily then that's what I will do. Thanks!
