GameRegistry
Making something known
Copyright © 2015 Curt Hill

2. Introduction We have seen this twice up until now
We used it to register a block and item
Until something is registered it does not exist to the game
Using an unregistered item generally crashes the server

3. Instantiation Almost every thing in GameRegistry is static
Thus, no copy of this thing exists or needs to be instantiated
There are two static nested classes but mostly it is just a collection of methods
Static methods and properties function like global variables and functions
Except that they need the class name as a prefix

4. What you have seen static Block registerBlock( Block, String)
static Item registerItem( Item, String name, String ID)

5. What you will see addRecipe addShapedRecipe addShapelessRecipe
addSmelting
Several of these exist in several signatures
We will consider them in subsequent presentations

6. Finds There are three find methods that we should consider Today:
findBlock and findItem
These allow us to find registered things
Maybe later
findItemStack

7. Find Block
Signature: static Block findBlock (String modId, String name)
The first parameter is the modid
I have been using “curtmod”
If it is a standard thing use “minecraft”
The second is the block name
If the block is not found you get a null returned, otherwise a handle
Always check if this has been successful

8. Find Item Signature: static Item findItem (String modId, String name)
The first parameter is the modid
I have been using “curtmod”
If it is a standard thing use “minecraft”
The second is the item name
If the item is not found you get a null returned, otherwise a handle
Always check if this has been successful

9. Finally
GameRegistry is the heart of what Minecraft knows about its contents
We will use this anytime we create a new block or item
We may also use this when we deal with behaviors
