|
|
For our first block, we are going to make a Copper Ore to go along with our Copper Ingot.
|
|
|
|
### Base Block
|
|
We're going to do something similar to what we did for [Basic Items](/tutorials/forge-modding-1102/basic-items/), create a base class for all of our blocks to extend to make our life a bit easier.
|
|
|
|
```java
|
|
package net.shadowfacts.tutorial.block;
|
|
|
|
import net.minecraft.block.Block;
|
|
import net.minecraft.block.material.Material;
|
|
import net.minecraft.creativetab.CreativeTabs;
|
|
import net.minecraft.item.ItemBlock;
|
|
import net.shadowfacts.tutorial.TutorialMod;
|
|
|
|
public class BlockBase extends Block {
|
|
|
|
protected String name;
|
|
|
|
public BlockBase(Material material, String name) {
|
|
super(material);
|
|
|
|
this.name = name;
|
|
|
|
setUnlocalizedName(name);
|
|
setRegistryName(name);
|
|
}
|
|
|
|
public void registerItemModel(ItemBlock itemBlock) {
|
|
TutorialMod.proxy.registerItemRenderer(itemBlock, 0, name);
|
|
}
|
|
|
|
@Override
|
|
public BlockBase setCreativeTab(CreativeTabs tab) {
|
|
super.setCreativeTab(tab);
|
|
return this;
|
|
}
|
|
|
|
}
|
|
```
|
|
|
|
This is almost exactly the same as our `ItemBase` class except it extends `Block` instead of `Item`. It sets the unlocalized and registry names, has a method to register the item model, and has an overridden version of `Block#setCreativeTab` that returns a `BlockBase`.
|
|
|
|
We'll also create a `BlockOre` class which extends `BlockBase` to make adding ore's a little easier.
|
|
|
|
```java
|
|
package net.shadowfacts.tutorial.block;
|
|
|
|
import net.minecraft.block.material.Material;
|
|
import net.minecraft.creativetab.CreativeTabs;
|
|
|
|
public class BlockOre extends BlockBase {
|
|
|
|
public BlockOre(String name) {
|
|
super(Material.ROCK, name);
|
|
|
|
setHardness(3f);
|
|
setResistance(5f);
|
|
}
|
|
|
|
@Override
|
|
public BlockOre setCreativeTab(CreativeTabs tab) {
|
|
super.setCreativeTab(tab);
|
|
return this;
|
|
}
|
|
|
|
}
|
|
```
|
|
|
|
### `ModBlocks`
|
|
|
|
Now let's create a `ModBlocks` class similar to `ModItems` to assist us when registering blocks.
|
|
|
|
```java
|
|
package net.shadowfacts.tutorial.block;
|
|
|
|
import net.minecraft.block.Block;
|
|
import net.minecraft.creativetab.CreativeTabs;
|
|
import net.minecraft.item.ItemBlock;
|
|
import net.minecraftforge.fml.common.registry.GameRegistry;
|
|
|
|
public class ModBlocks {
|
|
|
|
public static void init() {
|
|
|
|
}
|
|
|
|
private static <T extends Block> T register(T block, ItemBlock itemBlock) {
|
|
GameRegistry.register(block);
|
|
GameRegistry.register(itemBlock);
|
|
|
|
if (block instanceof BlockBase) {
|
|
((BlockBase)block).registerItemModel(itemBlock);
|
|
}
|
|
|
|
return block;
|
|
}
|
|
|
|
private static <T extends Block> T register(T block) {
|
|
ItemBlock itemBlock = new ItemBlock(block);
|
|
itemBlock.setRegistryName(block.getRegistryName());
|
|
return register(block, itemBlock);
|
|
}
|
|
|
|
}
|
|
```
|
|
|
|
This class is slightly different than our `ModItems` class due to the way blocks work in 1.9. In 1.9, we register the block and the `ItemBlock` separately whereas previously Forge would register the default `ItemBlock` automatically.
|
|
|
|
**Brief aside about how `ItemBlock`s work:** The `ItemBlock` for a given block is what is used as the inventory form of a given block. In the game, when you have a piece of Cobblestone in your inventory, you don't actually have on of the Cobblestone blocks in your inventory, you have one of the Cobblestone _`ItemBlock`s_ in your inventory.
|
|
|
|
Once again, we'll need to update our `preInit` method to call the `init` method of our `ModBlocks` class:
|
|
|
|
```java
|
|
@Mod.EventHandler
|
|
public void preInit(FMLPreInitializationEvent event) {
|
|
ModItems.init();
|
|
ModBlocks.init();
|
|
}
|
|
```
|
|
|
|
### Copper Ore
|
|
|
|
Now, because we have our `BlockBase` and `ModBlocks` classes in place, we can quickly add a new block:
|
|
|
|
```java
|
|
public static BlockOre oreCopper;
|
|
|
|
public static void init() {
|
|
oreCopper = register(new BlockOre("oreCopper").setCreativeTab(CreativeTabs.MATERIALS));
|
|
}
|
|
```
|
|
|
|
This will:
|
|
|
|
1. Create a new `BlockOre` with the name `oreCopper`.
|
|
2. Sets the creative tab of the block to the Materials tab.
|
|
3. Registers the block with the `GameRegistry`.
|
|
4. Registers the default `ItemBlock` with the `GameRegistry`.
|
|
|
|
|
|
Now, in the game, we can see our (untextured) copper ore block!
|
|
|
|
|
|
|
|
Next, we'll look at how to make a simple model for our copper ore block.
