Let's make some copper tools!
|
|
|
|
First we'll need to create a tool material for our new tools to use. We'll use Forge's `EnumHelper` class to add a value to the Minecraft `Item.ToolMaterial` enum.
|
|
|
|
```java
|
|
// ...
|
|
public class TutorialMod {
|
|
// ...
|
|
public static final Item.ToolMaterial copperToolMaterial = EnumHelper.addToolMaterial("COPPER", 2, 500, 6, 2, 14);
|
|
// ...
|
|
}
|
|
```
|
|
|
|
Each tool is going to be quite similar, so feel free to skip ahead to the one you want.

|
|
|
|
## Sword
|
|
First we'll create an `ItemSword` class in the `item.tool` package inside our mod package. This class will extend the vanilla `ItemSword` class and implement our `ItemModelProvider` interface.
|
|
|
|
In the constructor, we'll:
|
|
|
|
- Call the `super` constructor with the tool material
|
|
- Set the unlocalized and registry names
|
|
- Store the name for use in item model registration
|
|
|
|
We'll also override `registerItemModel` and use the stored `name` to register our item model.
|
|
|
|
```java
|
|
package net.shadowfacts.tutorial.item.tool;
|
|
|
|
import net.minecraft.item.Item;
|
|
import net.shadowfacts.tutorial.TutorialMod;
|
|
import net.shadowfacts.tutorial.item.ItemModelProvider;
|
|
|
|
public class ItemSword extends net.minecraft.item.ItemSword implements ItemModelProvider {
|
|
|
|
private String name;
|
|
|
|
public ItemSword(ToolMaterial material, String name) {
|
|
super(material);
|
|
setRegistryName(name);
|
|
setUnlocalizedName(name);
|
|
this.name = name;
|
|
}
|
|
|
|
@Override
|
|
public void registerItemModel(Item item) {
|
|
TutorialMod.proxy.registerItemRenderer(this, 0, name);
|
|
}
|
|
|
|
}
|
|
```
|
|
|
|
Next, we'll add our copper sword to our `ModItems` class simply by adding a field and initializing it using our `register` method.
|
|
|
|
```java
|
|
// ...
|
|
public class ModItems {
|
|
// ...
|
|
public static ItemSword copperSword;
|
|
|
|
public static void init() {
|
|
// ...
|
|
copperSword = register(new ItemSword(TutorialMod.copperToolMaterial, "copper_sword"));
|
|
}
|
|
// ...
|
|
}
|
|
```
|
|
|
|
We'll also create our JSON item model at `assets/tutorial/models/item/copper_sword.json`. Unlike our other item models, the parent for the model will be `item/handheld` instead of `item/generated`. `item/handheld` provides the transformations used by handheld items, such as tools.
|
|
|
|
```json
|
|
{
|
|
"parent": "item/handheld",
|
|
"textures": {
|
|
"layer0": "tutorial:items/copper_sword"
|
|
}
|
|
}
|
|
```
|
|
|
|
We'll also need the texture, which you can download [here](https://raw.githubusercontent.com/shadowfacts/TutorialMod/1.11/src/main/resources/assets/tutorial/textures/items/copper_sword.png).
|
|
|
|
And lastly, we'll add a localization entry for the sword.
|
|
|
|
```properties
|
|
# Items
|
|
# ...
|
|
item.copper_sword.name=Copper Sword
|
|
```
|
|
|
|
|
|
|
|
## Pickaxe
|
|
Let's create an `ItemPickaxe` class in the `item.tool` package of our mod. This class will extend the vanilla `ItemPickaxe` and implement our `ItemModelProvider` interface.
|
|
|
|
In our `ItemPickaxe` constructor we'll:
|
|
|
|
- Call the `super` constructor with the tool material
|
|
- Set the unlocalized name and registry names
|
|
- Store the name for use in the item model registration
|
|
|
|
We'll also override `registerItemModel` and use the stored `name` field to register our item model.
|
|
|
|
```java
|
|
package net.shadowfacts.tutorial.item.tool;
|
|
|
|
import net.minecraft.item.Item;
|
|
import net.shadowfacts.tutorial.TutorialMod;
|
|
import net.shadowfacts.tutorial.item.ItemModelProvider;
|
|
|
|
public class ItemPickaxe extends net.minecraft.item.ItemPickaxe implements ItemModelProvider {
|
|
|
|
private String name;
|
|
|
|
public ItemPickaxe(ToolMaterial material, String name) {
|
|
super(material);
|
|
setRegistryName(name);
|
|
setUnlocalizedName(name);
|
|
this.name = name;
|
|
}
|
|
|
|
@Override
|
|
public void registerItemModel(Item item) {
|
|
TutorialMod.proxy.registerItemRenderer(this, 0, name);
|
|
}
|
|
|
|
}
|
|
```
|
|
|
|
Next, we'll add our copper pickaxe to our `ModItems` class simply by adding a field and initializing it using our `register` method.
|
|
|
|
```java
|
|
// ...
|
|
public class ModItems {
|
|
// ...
|
|
public static ItemPickaxe copperPickaxe;
|
|
|
|
public static void init() {
|
|
// ...
|
|
copperPickaxe = register(new ItemPickaxe(TutorialMod.copperToolMaterial, "copper_pickaxe"));
|
|
}
|
|
// ...
|
|
}
|
|
```
|
|
|
|
We'll create a JSON model for our item at `assets/tutorial/models/item/copper_pickaxe.json`. This model will have a parent of `item/handheld` instead of `item/generated` so it inherits the transformations for handheld models.
|
|
|
|
```json
|
|
{
|
|
"parent": "item/handheld",
|
|
"textures": {
|
|
"layer0": "tutorial:items/copper_pickaxe"
|
|
}
|
|
}
|
|
```
|
|
|
|
You can download the texture for the copper pickaxe [here](https://raw.githubusercontent.com/shadowfacts/TutorialMod/1.11/src/main/resources/assets/tutorial/textures/items/copper_pickaxe.png).
|
|
|
|
Lastly, we'll need a localization entry for the pick.
|
|
|
|
```properties
|
|
# Items
|
|
# ...
|
|
item.copper_pickaxe.name=Copper Pickaxe
|
|
```
|
|
|
|
|
|
|
|
## Axe
|
|
First off, we'll need an `ItemAxe` class that extends the vanilla `ItemAxe` class and implements our `ItemModelProvider` interface.
|
|
|
|
If you look at the vanilla `ItemAxe` class, you'll notice that it has two constructors. One of them takes only a `ToolMaterial` whereas the other takes a `ToolMaterial` and two `float`s. Only vanilla `ToolMaterial`s will work with the `ToolMaterial` only constructor, any modded materials will cause an `ArrayIndexOutOfBoundsException` because of the hardcoded values in the `float` arrays in the `ItemAxe` class. Forge provides the secondary constructor that accepts the two `float`s as well, allowing modders to add axes with their own tool materials.
|
|
|
|
In the `ItemPickaxe` constructor, we will:
|
|
|
|
- Call the `super` constructor with the tool material and the damage and attack speeds used by the vanilla iron axe.
|
|
- Set the unlocalized and registry names
|
|
- Store the name for use in the item model registration
|
|
|
|
Additionally, we'll override `registerItemModel` and use the stored `name` to register our model.
|
|
|
|
```java
|
|
package net.shadowfacts.tutorial.item.tool;
|
|
|
|
import net.minecraft.item.Item;
|
|
import net.shadowfacts.tutorial.TutorialMod;
|
|
import net.shadowfacts.tutorial.item.ItemModelProvider;
|
|
|
|
public class ItemAxe extends net.minecraft.item.ItemAxe implements ItemModelProvider {
|
|
|
|
private String name;
|
|
|
|
public ItemAxe(ToolMaterial material, String name) {
|
|
super(material, 8f, -3.1f);
|
|
setRegistryName(name);
|
|
setUnlocalizedName(name);
|
|
this.name = name;
|
|
}
|
|
|
|
@Override
|
|
public void registerItemModel(Item item) {
|
|
TutorialMod.proxy.registerItemRenderer(this, 0, name);
|
|
}
|
|
|
|
}
|
|
```
|
|
|
|
Next, we'll add our copper axe to our `ModItems` class simply by adding a field and initializing it using our `register` method.
|
|
|
|
```java
|
|
// ...
|
|
public class ModItems {
|
|
// ...
|
|
public static ItemAxe copperAxe;
|
|
|
|
public static void init() {
|
|
// ...
|
|
copperAxe = register(new ItemAxe(TutorialMod.copperToolMaterial, "copper_axe"));
|
|
}
|
|
// ...
|
|
}
|
|
```
|
|
|
|
Additionally, we'll need a JSON item model. We'll create it at `assets/tutorials/models/item/copper_axe.json`.
|
|
|
|
Our model will have a parent of `item/handheld` instead of `item/generated` so it has the same transformations used by other hand-held items.
|
|
|
|
```json
|
|
{
|
|
"parent": "item/handheld",
|
|
"textures": {
|
|
"layer0": "tutorial:items/copper_axe"
|
|
}
|
|
}
|
|
```
|
|
|
|
You can download the texture for the copper axe [here](https://raw.githubusercontent.com/shadowfacts/TutorialMod/1.11/src/main/resources/assets/tutorial/textures/items/copper_axe.png).
|
|
|
|
Lastly, we'll need a localization entry for our axe.
|
|
|
|
```properties
|
|
# Items
|
|
# ...
|
|
item.copper_axe.name=Copper Axe
|
|
```
|
|
|
|
|
|
|
|
## Shovel
|
|
Firstly we'll create an `ItemShovel` class that extends the vanilla `ItemSpade` class and implements our `ItemModelProvider` interface.
|
|
|
|
In the `ItemShovel` constructor, we'll:
|
|
|
|
- Call the `super` constructor with the tool material used
|
|
- Set the unlocalized and registry names
|
|
- Store the name to be used for item model registration
|
|
|
|
We'll also need to implement `registerItemModel` and register a item model for our shovel.
|
|
|
|
```java
|
|
package net.shadowfacts.tutorial.item.tool;
|
|
|
|
import net.minecraft.item.Item;
|
|
import net.minecraft.item.ItemSpade;
|
|
import net.shadowfacts.tutorial.TutorialMod;
|
|
import net.shadowfacts.tutorial.item.ItemModelProvider;
|
|
|
|
public class ItemShovel extends ItemSpade implements ItemModelProvider {
|
|
|
|
private String name;
|
|
|
|
public ItemShovel(ToolMaterial material, String name) {
|
|
super(material);
|
|
setRegistryName(name);
|
|
setUnlocalizedName(name);
|
|
this.name = name;
|
|
}
|
|
|
|
@Override
|
|
public void registerItemModel(Item item) {
|
|
TutorialMod.proxy.registerItemRenderer(this, 0, name);
|
|
}
|
|
|
|
}
|
|
```
|
|
|
|
Next, we'll add our copper shovel to our `ModItems` class simply by adding a field and initializing it using our `register` method.
|
|
|
|
```java
|
|
// ...
|
|
public class ModItems {
|
|
// ...
|
|
public static ItemShovel copperShovel;
|
|
|
|
public static void init() {
|
|
// ...
|
|
copperShovel = register(new ItemShovel(TutorialMod.copperToolMaterial, "copper_shovel"));
|
|
}
|
|
// ...
|
|
}
|
|
```
|
|
|
|
Next, we'll create a JSON item model for our shovel at `assets/tutorial/models/item/copper_shovel.json`. This model will have a parent of `item/handheld`, unlike our previous item models, so it inherits the transformations used by handheld items.
|
|
|
|
```json
|
|
{
|
|
"parent": "item/handheld",
|
|
"textures": {
|
|
"layer0": "tutorial:items/copper_shovel"
|
|
}
|
|
}
|
|
```
|
|
|
|
You can download the texture for our shovel [here](https://raw.githubusercontent.com/shadowfacts/TutorialMod/master/src/main/resources/assets/tutorial/textures/items/copper_shovel.png).
|
|
|
|
We'll also need a localization entry for our shovel.
|
|
|
|
```properties
|
|
# Items
|
|
# ...
|
|
item.copper_shovel.name=Copper Shovel
|
|
```
|
|
|
|
|
|
|
|
## Hoe
|
|
Let's create an `ItemHoe` class that extends the vanilla `ItemHoe` class and implements our `ItemModelProvider` interface.
|
|
|
|
In the `ItemHoe` constructor, we'll:
|
|
|
|
- Call the `super` constructor with the tool material
|
|
- Set the unlocalized and registry names
|
|
- Store the item name to be used for item model registration
|
|
|
|
We'll also need to implement `registerItemModel` and register an item model for our hoe.
|
|
|
|
```java
|
|
package net.shadowfacts.tutorial.item.tool;
|
|
|
|
import net.minecraft.item.Item;
|
|
import net.shadowfacts.tutorial.TutorialMod;
|
|
import net.shadowfacts.tutorial.item.ItemModelProvider;
|
|
|
|
public class ItemHoe extends net.minecraft.item.ItemHoe implements ItemModelProvider {
|
|
|
|
private String name;
|
|
|
|
public ItemHoe(ToolMaterial material, String name) {
|
|
super(material);
|
|
setRegistryName(name);
|
|
setUnlocalizedName(name);
|
|
this.name = name;
|
|
}
|
|
|
|
@Override
|
|
public void registerItemModel(Item item) {
|
|
TutorialMod.proxy.registerItemRenderer(this, 0, name);
|
|
}
|
|
|
|
}
|
|
```
|
|
|
|
Next, we'll add our hoe to our `ModItems` class simply by adding a field and initializing it using our `register` method.
|
|
|
|
```java
|
|
// ...
|
|
public class ModItems {
|
|
// ...
|
|
public static ItemSword copperHoe;
|
|
|
|
public static void init() {
|
|
// ...
|
|
copperHoe = register(new ItemSword(TutorialMod.copperToolMaterial, "copper_hoe"));
|
|
}
|
|
// ...
|
|
}
|
|
```
|
|
|
|
Next, we'll create a JSON item model for our hoe at `assets/tutorial/models/item/copper_hoe.json`. This model will have a parent of `item/handheld` instead of `item/generated` so it inherits the transformations used by vanilla handheld items.
|
|
|
|
```json
|
|
{
|
|
"parent": "item/handheld",
|
|
"textures": {
|
|
"layer0": "tutorial:items/copper_hoe"
|
|
}
|
|
}
|
|
```
|
|
|
|
You can download the copper hoe texture [here](https://raw.githubusercontent.com/shadowfacts/TutorialMod/master/src/main/resources/assets/tutorial/textures/items/copper_hoe.png).
|
|
|
|
Lastly, we'll need a localization entry for our hoe.
|
|
|
|
```properties
|
|
# Items
|
|
# ...
|
|
item.copper_hoe.name=Copper Hoe
|
|
```
|
|
|
|
|
