How do i add new properties to existing blocks with a mod?

Hello

 

I know, how i can add properties like rotating towards player while placing to new blocks, wich i add in a mod.

But how can i add this to existing vanilla-blocks, like the brewing-stand?

You could use events or registry replace the block. Events will be more compatible.

I´m not sure, how to put this into an event?

Vanilla sets the BlockState when you right click from an item block or in the updatePostPlacement method in blocks. I would look for events containing “Item”, “Block”, “Click”, “Interact”, “Place”. Then find out which one is appropriate to use.
