Minecraft 1.12.2模组开发(三十九) 反应器(TileEntity方块实体)
2024-06-15 22:42:48
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。
ContainerVirusGenerator.java
package com.joy187.rejoymod.blocks.tileEntity.virusGenerator;import com.joy187.rejoymod.recipe.special.VirusGeneratorRecipes;

import net.minecraftforge.items.SlotItemHandler;public class ContainerVirusGenerator extends Container {private final TileEntityVirusGenerator tileentity;//我们做的是类熔炉的机器，所以设置4个参数：熔炼时间，熔炼要求时间，燃料时间，当前燃烧时间private int cookTime, totalCookTime, burnTime, currentBurnTime;public ContainerVirusGenerator(InventoryPlayer player, TileEntityVirusGenerator tileentity){this.tileentity = tileentity;IItemHandler handler = tileentity.getCapability(CapabilityItemHandler.ITEM_HANDLER_CAPABILITY, null);//设置物品槽的总数与每个槽位的编号、坐标this.addSlotToContainer(new SlotItemHandler(handler, 0, 26, 11));this.addSlotToContainer(new SlotItemHandler(handler, 1, 26, 59));this.addSlotToContainer(new SlotItemHandler(handler, 2, 7, 35));this.addSlotToContainer(new SlotItemHandler(handler, 3, 81, 36));//把Inventory中的三行物品栏和一行个人栏展示出来for(int y = 0; y < 3; y++){for(int x = 0; x < 9; x++){this.addSlotToContainer(new Slot(player, x + y*9 + 9, 8 + x*18, 84 + y*18));}}for(int x = 0; x < 9; x++){this.addSlotToContainer(new Slot(player, x, 8 + x * 18, 142));}}@Overridepublic void detectAndSendChanges(){super.detectAndSendChanges();for(int i = 0; i < this.listeners.size(); ++i){IContainerListener listener = (IContainerListener)this.listeners.get(i);//我们一共有4个参数，所以要监视这4个参数的实时状态if(this.cookTime != this.tileentity.getField(2)) listener.sendWindowProperty(this, 2, this.tileentity.getField(2));if(this.burnTime != this.tileentity.getField(0)) listener.sendWindowProperty(this, 0, this.tileentity.getField(0));if(this.currentBurnTime != this.tileentity.getField(1)) listener.sendWindowProperty(this, 1, this.tileentity.getField(1));if(this.totalCookTime != this.tileentity.getField(3)) listener.sendWindowProperty(this, 3, this.tileentity.getField(3));}this.cookTime = this.tileentity.getField(2);this.burnTime = this.tileentity.getField(0);this.currentBurnTime = this.tileentity.getField(1);this.totalCookTime = this.tileentity.getField(3);}@Override@SideOnly(Side.CLIENT)public void updateProgressBar(int id, int data){this.tileentity.setField(id, data);}@Overridepublic boolean canInteractWith(EntityPlayer playerIn){return this.tileentity.isUsableByPlayer(playerIn);}@Overridepublic ItemStack transferStackInSlot(EntityPlayer playerIn, int index){ItemStack stack = ItemStack.EMPTY;Slot slot = (Slot)this.inventorySlots.get(index);if(slot != null && slot.getHasStack()){ItemStack stack1 = slot.getStack();stack = stack1.copy();if(index == 3){if(!this.mergeItemStack(stack1, 4, 40, true)) return ItemStack.EMPTY;slot.onSlotChange(stack1, stack);}else if(index != 2 && index != 1 && index != 0){Slot slot1 = (Slot)this.inventorySlots.get(index + 1);if(!VirusGeneratorRecipes.getInstance().getSinteringResult(stack1, slot1.getStack()).isEmpty()){if(!this.mergeItemStack(stack1, 0, 2, false)){return ItemStack.EMPTY;}else if(TileEntityVirusGenerator.isItemFuel(stack1)){if(!this.mergeItemStack(stack1, 2, 3, false)) return ItemStack.EMPTY;}else if(TileEntityVirusGenerator.isItemFuel(stack1)){if(!this.mergeItemStack(stack1, 2, 3, false)) return ItemStack.EMPTY;}else if(TileEntityVirusGenerator.isItemFuel(stack1)){if(!this.mergeItemStack(stack1, 2, 3, false)) return ItemStack.EMPTY;}else if(index >= 4 && index < 31){if(!this.mergeItemStack(stack1, 31, 40, false)) return ItemStack.EMPTY;}else if(index >= 31 && index < 40 && !this.mergeItemStack(stack1, 4, 31, false)){return ItemStack.EMPTY;}}}else if(!this.mergeItemStack(stack1, 4, 40, false)){return ItemStack.EMPTY;}if(stack1.isEmpty()){slot.putStack(ItemStack.EMPTY);}else{slot.onSlotChanged();}if(stack1.getCount() == stack.getCount()) return ItemStack.EMPTY;slot.onTake(playerIn, stack1);}return stack;}
}
同时在tileEntity包内新建GuiVirusGenerator类:
GuiVirusGenerator.java
package com.joy187.rejoymod.blocks.tileEntity.virusGenerator;import com.joy187.rejoymod.util.Reference;
import net.minecraft.client.gui.inventory.GuiContainer;
import net.minecraft.client.renderer.GlStateManager;
import net.minecraft.entity.player.InventoryPlayer;
import net.minecraft.util.ResourceLocation;
public class GuiVirusGenerator extends GuiContainer
{//将第一步的GUI界面的路径传给TEXTURESprivate 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){super(new ContainerVirusGenerator(player, tileentity));this.player = player;this.tileentity = tileentity;}@Overrideprotected void drawGuiContainerForegroundLayer(int mouseX, int mouseY){String tileName = this.tileentity.getDisplayName().getUnformattedText();//在GUI界面的上方显示出机器的名字this.fontRenderer.drawString(tileName, (this.xSize / 2 - this.fontRenderer.getStringWidth(tileName) / 2) + 3, 8, 4210752);this.fontRenderer.drawString(this.player.getDisplayName().getUnformattedText(), 122, this.ySize - 96 + 2, 4210752);}//显示出整个GUI界面@Overrideprotected void drawGuiContainerBackgroundLayer(float partialTicks, int mouseX, int mouseY){GlStateManager.color(1.0f, 1.0f, 1.0f, 1.0f);this.mc.getTextureManager().bindTexture(TEXTURES);this.drawTexturedModalRect(this.guiLeft, this.guiTop, 0, 0, this.xSize, this.ySize);if(TileEntityVirusGenerator.isBurning(tileentity)){int k = this.getBurnLeftScaled(13);this.drawTexturedModalRect(this.guiLeft + 8, this.guiTop + 54 + 12 - k, 176, 12 - k, 14, k + 1);}int l = this.getCookProgressScaled(24);this.drawTexturedModalRect(this.guiLeft + 44, this.guiTop + 36, 176, 14, l + 1, 16);}private int getBurnLeftScaled(int pixels){int i = this.tileentity.getField(1);if(i == 0) i = 200;return this.tileentity.getField(0) * pixels / i;}private int getCookProgressScaled(int pixels){int i = this.tileentity.getField(2);int j = this.tileentity.getField(3);return j != 0 && i != 0 ? i * pixels / j : 0;}
}
3.GUI做好之后我们开始定义一个机器类，在tileEntity包内新建TileEntityVirusGenerator类：

}
在tileEntity包中新建一个BlockVirusGenerator方块类用于实现方块实体：

{public static final PropertyDirection FACING = BlockHorizontal.FACING;//给机器增加一个燃烧的状态参数public static final PropertyBool BURNING = PropertyBool.create("burning");private static boolean keepInventory;public BlockVirusGenerator(String name){super(name, Material.IRON);setSoundType(SoundType.METAL);this.setDefaultState(this.blockState.getBaseState().withProperty(FACING, EnumFacing.NORTH).withProperty(BURNING, false));}@Overridepublic Item getItemDropped(IBlockState state, Random rand, int fortune){return Item.getItemFromBlock(ModBlocks.VIRUS_GENERATOR);}@Overridepublic ItemStack getItem(World worldIn, BlockPos pos, IBlockState state){return new ItemStack(ModBlocks.VIRUS_GENERATOR);}@Overridepublic boolean onBlockActivated(World worldIn, BlockPos pos, IBlockState state, EntityPlayer playerIn, EnumHand hand, EnumFacing facing, float hitX, float hitY, float hitZ){if(!worldIn.isRemote){//点击方块显示我们的GUIplayerIn.openGui(IdlFramework.instance, ModGuiElementLoader.GUI_VIRUS_GENERATOR, worldIn, pos.getX(), pos.getY(), pos.getZ());}return true;}@Overridepublic void onBlockAdded(World worldIn, BlockPos pos, IBlockState state){if (!worldIn.isRemote){IBlockState north = worldIn.getBlockState(pos.north());IBlockState south = worldIn.getBlockState(pos.south());IBlockState west = worldIn.getBlockState(pos.west());IBlockState east = worldIn.getBlockState(pos.east());EnumFacing face = (EnumFacing)state.getValue(FACING);if (face == EnumFacing.NORTH && north.isFullBlock() && !south.isFullBlock()) face = EnumFacing.SOUTH;else if (face == EnumFacing.SOUTH && south.isFullBlock() && !north.isFullBlock()) face = EnumFacing.NORTH;else if (face == EnumFacing.WEST && west.isFullBlock() && !east.isFullBlock()) face = EnumFacing.EAST;else if (face == EnumFacing.EAST && east.isFullBlock() && !west.isFullBlock()) face = EnumFacing.WEST;worldIn.setBlockState(pos, state.withProperty(FACING, face), 2);}}public static void setState(boolean active, World worldIn, BlockPos pos){IBlockState state = worldIn.getBlockState(pos);TileEntity tileentity = worldIn.getTileEntity(pos);keepInventory = true;//如果机器在启动，就把机器设置为开启if(active) worldIn.setBlockState(pos, ModBlocks.VIRUS_GENERATOR.getDefaultState().withProperty(FACING, state.getValue(FACING)).withProperty(BURNING, true), 3);else worldIn.setBlockState(pos, ModBlocks.VIRUS_GENERATOR.getDefaultState().withProperty(FACING, state.getValue(FACING)).withProperty(BURNING, false), 3);keepInventory = false;if(tileentity != null){tileentity.validate();worldIn.setTileEntity(pos, tileentity);}}@Overridepublic boolean hasTileEntity(IBlockState state){return true;}@Overridepublic TileEntity createTileEntity(World world, IBlockState state){return new TileEntityVirusGenerator();}@Overridepublic IBlockState getStateForPlacement(World world, BlockPos pos, EnumFacing facing, float hitX, float hitY, float hitZ, int meta, EntityLivingBase placer, EnumHand hand){return this.getDefaultState().withProperty(FACING, placer.getHorizontalFacing().getOpposite());}@Overridepublic void onBlockPlacedBy(World worldIn, BlockPos pos, IBlockState state, EntityLivingBase placer, ItemStack stack){worldIn.setBlockState(pos, this.getDefaultState().withProperty(FACING, placer.getHorizontalFacing().getOpposite()), 2);}@Overridepublic EnumBlockRenderType getRenderType(IBlockState state){return EnumBlockRenderType.MODEL;}@Overridepublic IBlockState withRotation(IBlockState state, Rotation rot){return state.withProperty(FACING, rot.rotate((EnumFacing)state.getValue(FACING)));}@Overridepublic IBlockState withMirror(IBlockState state, Mirror mirrorIn){return state.withRotation(mirrorIn.toRotation((EnumFacing)state.getValue(FACING)));}@Overrideprotected BlockStateContainer createBlockState(){return new BlockStateContainer(this, new IProperty[] {BURNING,FACING});}@Overridepublic IBlockState getStateFromMeta(int meta){EnumFacing facing = EnumFacing.getFront(meta);if(facing.getAxis() == EnumFacing.Axis.Y) facing = EnumFacing.NORTH;return this.getDefaultState().withProperty(FACING, facing);}@Overridepublic int getMetaFromState(IBlockState state){return ((EnumFacing)state.getValue(FACING)).getIndex();}//破坏机器，就把4个槽位的物品都弹出来public void breakBlock(World worldIn, BlockPos pos, IBlockState state){TileEntityVirusGenerator tileentity = (TileEntityVirusGenerator)worldIn.getTileEntity(pos);if(!keepInventory){worldIn.spawnEntity(new EntityItem(worldIn, pos.getX(), pos.getY(), pos.getZ(), tileentity.handler.getStackInSlot(0)));worldIn.spawnEntity(new EntityItem(worldIn, pos.getX(), pos.getY(), pos.getZ(), tileentity.handler.getStackInSlot(1)));worldIn.spawnEntity(new EntityItem(worldIn, pos.getX(), pos.getY(), pos.getZ(), tileentity.handler.getStackInSlot(2)));worldIn.spawnEntity(new EntityItem(worldIn, pos.getX(), pos.getY(), pos.getZ(), tileentity.handler.getStackInSlot(3)));}tileentity.setField(0,0);tileentity.setField(1,0);tileentity.setField(2,0);tileentity.setField(3,200);super.breakBlock(worldIn, pos, state);}
}在tileEntity包中新建一个TileEntityHandler类将我们所有的方块机器进行注册：
TileEntityHandler.java
import com.joy187.rejoymod.blocks.tileEntity.virusGenerator.TileEntityVirusGenerator;
import com.joy187.rejoymod.util.Reference;
import net.minecraft.util.ResourceLocation;
import net.minecraftforge.fml.common.registry.GameRegistry;public class TileEntityHandler
{public static void registerTileEntities(){//GameRegistry.registerTileEntity(TileEntityCopperChest.class, new ResourceLocation(Reference.MODID + ":copper_chest"));GameRegistry.registerTileEntity(TileEntityVirusGenerator.class, new ResourceLocation(Reference.Mod_ID + ":virus_generator"));}
}
4.在gui包(没有就新建一个)中新建一个ModGuiElementLoader类:
ModGuiElementLoader.java
package com.joy187.rejoymod.gui;import com.joy187.rejoymod.IdlFramework;
import com.joy187.rejoymod.blocks.tileEntity.virusGenerator.ContainerVirusGenerator;
import com.joy187.rejoymod.blocks.tileEntity.virusGenerator.GuiVirusGenerator;

import com.joy187.rejoymod.gui.expOne.GuiContainerDemo;
import net.minecraft.entity.player.EntityPlayer;
import net.minecraft.util.math.BlockPos;
import net.minecraft.world.World;
import net.minecraftforge.fml.common.network.IGuiHandler;
import net.minecraftforge.fml.common.network.NetworkRegistry;import javax.annotation.Nullable;public class ModGuiElementLoader implements IGuiHandler {//给模组中所有机器的GUI依次编号public static final int GUI_VIRUS_GENERATOR = 1;public static final int GUI_DEMO = 2;public static final int GUI_RESEARCH = 3;public ModGuiElementLoader(){NetworkRegistry.INSTANCE.registerGuiHandler(IdlFramework.instance, this);}//sitch语句选择显示服务端的Container界面@Nullable@Overridepublic 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@Overridepublic 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
@EventHandlerpublic 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:
@SubscribeEventpublic 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"}
}
同时需要制作方块工作时的模型贴图文件：
virus_generator_li.json
{"parent": "block/orientable","textures": {"top": "rejoymod:blocks/sintering_furnace_side","front": "rejoymod:blocks/sintering_furnace_front_on","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):
