说到方块实体(TileEntity)，可以理解为一种功能性方块，比如熔炉，箱子，附魔台等。
我们今天来做一个类似于熔炉的反应器
熔炉逻辑: 放入燃料-> 放入物品 -> 获取产出物品
1.首先我们发现熔炉有一个GUI界面，所以我们也要给自己的机器先准备一个GUI界面，可以用PS等软件进行制作(大小为256×256，在教程最后可以直接下载):
将做好的GUI界面放入src\main\resources\assets\你的modid\textures\gui这个地址下:
2.在开发包的blocks文件夹下新建tileEntity包 -> tileEntity包内新建ContainerVirusGenerator类:
由于我们这次准备了4个物品槽用于反应，1个为燃料槽(2号)，2个为原料槽(0号、1号)，1个为产物槽(3号):
你可以修改每个槽的x，y坐标来进行修改，但同时你要修改自己的第1步中的GUI贴图。

同时在tileEntity包内新建GuiVirusGenerator类:

public class GuiVirusGenerator extends GuiContainer
{
//将第一步的GUI界面的路径传给TEXTURES
private static final ResourceLocation TEXTURES = new ResourceLocation(Reference.Mod_ID + ":textures/gui/virus_generator.png");
private final InventoryPlayer player;
private final TileEntityVirusGenerator tileentity;
public GuiVirusGenerator(InventoryPlayer player, TileEntityVirusGenerator tileentity)
{

}
@Override

//在GUI界面的上方显示出机器的名字

}
//显示出整个GUI界面
@Override

{

}

this.drawTexturedModalRect(this.guiLeft + 44, this.guiTop + 36, 176, 14, l + 1, 16);
}
private int getBurnLeftScaled(int pixels)

@Nullable
@Override
public Object getServerGuiElement(int ID, EntityPlayer player, World world, int x, int y, int z) {
switch (ID)
{
case GUI_VIRUS_GENERATOR:
return new ContainerVirusGenerator(player.inventory,(TileEntityVirusGenerator) world.getTileEntity(new BlockPos(x,y,z)));
default:
return null;
}
}
//sitch语句选择显示客户端的Gui界面
@Nullable
@Override
public Object getClientGuiElement(int ID, EntityPlayer player, World world, int x, int y, int z) {
switch (ID)
{
case GUI_VIRUS_GENERATOR:
return new GuiVirusGenerator(player.inventory,(TileEntityVirusGenerator) world.getTileEntity(new BlockPos(x,y,z)));
default:
return null;
}
}
}
5.给我们的机器添加其燃烧的配方，在tileEntity包中新建VirusGeneratorRecipes类：
VirusGeneratorRecipes.java
import com.google.common.collect.HashBasedTable;
import com.google.common.collect.Maps;
import com.google.common.collect.Table;
import com.joy187.rejoymod.item.ModItems;
import net.minecraft.init.Items;
import net.minecraft.item.ItemStack;
import java.util.Map;
import java.util.Map.Entry;
public class VirusGeneratorRecipes {
private static final VirusGeneratorRecipes INSTANCE = new VirusGeneratorRecipes();
private final Table<ItemStack, ItemStack, ItemStack> smeltingList = HashBasedTable.<ItemStack, ItemStack, ItemStack>create();
private final Map<ItemStack, Float> experienceList = Maps.<ItemStack, Float>newHashMap();
public static VirusGeneratorRecipes getInstance()
{
return INSTANCE;
}
private VirusGeneratorRecipes()
{
//我们的配方一共3个物品：2个原料+1个产物
addGeneratorRecipe(new ItemStack(Items.ROTTEN_FLESH), new ItemStack(Items.GOLD_INGOT), new ItemStack(Items.NETHER_STAR), 5.0F);
//addGeneratorRecipe(new ItemStack(Items.ROTTEN_FLESH), new ItemStack(Items.IRON_INGOT), new ItemStack(Items.DIAMOND), 5.0F);
}
public void addGeneratorRecipe(ItemStack input1, ItemStack input2, ItemStack result, float experience)
{
if(getSinteringResult(input1, input2) != ItemStack.EMPTY) return;
this.smeltingList.put(input1, input2, result);
this.experienceList.put(result, Float.valueOf(experience));
}
public ItemStack getSinteringResult(ItemStack input1, ItemStack input2)
{
for(Entry<ItemStack, Map<ItemStack, ItemStack>> entry : this.smeltingList.columnMap().entrySet())
{
if(this.compareItemStacks(input1, (ItemStack)entry.getKey()))
{
for(Entry<ItemStack, ItemStack> ent : entry.getValue().entrySet())
{
if(this.compareItemStacks(input2, (ItemStack)ent.getKey()))
{
return (ItemStack)ent.getValue();
}
}
}
}
return ItemStack.EMPTY;
}
private boolean compareItemStacks(ItemStack stack1, ItemStack stack2)
{
return stack2.getItem() == stack1.getItem() && (stack2.getMetadata() == 32767 || stack2.getMetadata() == stack1.getMetadata());
}
public Table<ItemStack, ItemStack, ItemStack> getDualSmeltingList()
{
return this.smeltingList;
}
public float getGeneratorExperience(ItemStack stack)
{
for (Entry<ItemStack, Float> entry : this.experienceList.entrySet())
{
if(this.compareItemStacks(stack, (ItemStack)entry.getKey()))
{
return ((Float)entry.getValue()).floatValue();
}
}
return 0.2F;
}
}
5.在Main.java的Init()中添加ModGuiElementLoader的初始化:
Main.java
@EventHandler
public static void Init(FMLInitializationEvent event) {
//ModRecipes.Init();
//RegisterTileEntity();
//initRegistries(event);
//ModSpawn.registerSpawnList();
//添加GUI初始化
new ModGuiElementLoader();
//NetworkHandler.init();
//LogWarning("%s has finished its initializations", MODID);
}
6.在ModBlocks中声明我们的方块:
ModBlocks.java
public static final Block VIRUS_GENERATOR = new BlockVirusGenerator("virus_generator");
在RegistryHandler.java中的onBlockRegister()中添加TileEntityHandler的注册语句:
@SubscribeEvent
public static void onBlockRegister(RegistryEvent.Register<Block> event) {
TileEntityHandler.registerTileEntities();
}
7.Java包的代码部分结束，找到resources包:
在en_us.lang中添加机器方块的名称:
container.virus_generator=Virus Analyser
tile.virus_generator.name=Virus Analyser
在blockstates包中新建virus_generator.json用于表示机器的不同形态下的模型
virus_generator.json
{
"variants":
{
"burning=false,facing=north": { "model": "rejoymod:virus_generator" },
"burning=false,facing=east": { "model": "rejoymod:virus_generator", "y": 90 },
"burning=false,facing=south": { "model": "rejoymod:virus_generator", "y": 180 },
"burning=false,facing=west": { "model": "rejoymod:virus_generator", "y": 270 },
"burning=true,facing=north": { "model": "rejoymod:virus_generator_li" },
"burning=true,facing=east": { "model": "rejoymod:virus_generator_li", "y": 90 },
"burning=true,facing=south": { "model": "rejoymod:virus_generator_li", "y": 180 },
"burning=true,facing=west": { "model": "rejoymod:virus_generator_li", "y":270 }
}
}
在models/block包中新建virus_generator.json，显示机器的模型贴图地址
virus_generator.json
{
"parent": "block/orientable",
"textures": {
"top": "rejoymod:blocks/sintering_furnace_side",
"front": "rejoymod:blocks/sintering_furnace_front_off",
"side": "rejoymod:blocks/sintering_furnace_side"
}
}
在models/item包中新建virus_generator.json，显示手拿机器的模型
virus_generator.json
{
"parent": "rejoymod:block/virus_generator"
}
在textures/blocks包中添加我们机器的3个贴图(一个为机器四周贴图，一个为机器关闭时贴图，一个为机器运作贴图):
8.保存所有文件 -> 运行游戏
首先拿出我们的机器并放置下来，外观显示正常
第5步中我们的反应器的一个配方为燃料+腐肉+金锭 ->下界之星，我们分别把东西摆进机器:
的确可以产出我们想要的东西，燃料和原料也都正常的消耗了。
同时我们发现在反应器工作时，机器同样显示为工作时的贴图:
本次用到的GUI界面(保存为.png格式，可根据PS软件进行修改):
