Whats the best way to change vanilla blocks behaviour when events are not available?

[Insane96MCP]

Let's say I want to change how Farmland works (e.g. want to add a new propertyInteger to the block), or beacon.
What should I do? Create a new block, with most of the same attributes and methods, and replace (using events) the vanilla one? Or there's some other method that works better?

The new registry system allows to override blocks, simply register a new block with the same registry name to override it.

The problem is that I've tried but the game crashes saying that the block has been registered twice:

ResourceLocation location = new ResourceLocation("minecraft", "farmland");
newFarmland = new BlockNewFarmland();
newFarmland.setRegistryName(location);
newFarmland.setCreativeTab(CreativeTabs.DECORATIONS);
GameRegistry.register(newFarmland);
GameRegistry.register(new ItemBlock(newFarmland), location);

What's the point of this reply?

Which version are you using? By the looks of it, it's not 1.12; which is where the new registry system was introduced.

 

Before 1.12 there was the substitution alias system (GameRegistry.addSubstitutionAlias), though I never managed to get it working properly myself.

Uhm well, I may have to move my mod to 1.12

Prior to the addition of the registry events, this is the wrong way to do item substitution. You were supposed to use GameRegistry.addSubstitutionAlias which may throw a ExistingSubstitutionException so you had to wrap it in a try...catch block.
