[1.7.2] Custom GUI and Implementing IInventory

Posted July 7, 201411 yr

I am wanting to create a custom inventory for my custom entity. I have begun by implementing IInventory and have added the unimplemented methods. I am using the wiki tutorial for help (http://www.minecraftforge.net/wiki/Containers_and_GUIs) but I have some methods that aren't entirely the same, plus the wiki doesn't explain a whole lot so some of my code is giving me errors.

It hasn't used these methods, so I don't know what they are used for/how to use them:

@Override
public boolean hasCustomInventoryName() {

	return false;

}

@Override
public void markDirty() {



}

@Override
public void openInventory() {

	//It has got openChest()

}

@Override
public void closeInventory() {

	//and closeChest() so I am wondering if they are the same

}

@Override
public boolean isItemValidForSlot(int var1, ItemStack var2) {

	return false;

}

None of those appear on the wiki tutorial but these ones do, however I don't know how to use them correctly as there is no explanation.

@Override
        public void readFromNBT(NBTTagCompound tagCompound) {
                super.readFromNBT(tagCompound);
                
                NBTTagList tagList = tagCompound.getTagList("Inventory");
                for (int i = 0; i < tagList.tagCount(); i++) {
                        NBTTagCompound tag = (NBTTagCompound) tagList.tagAt(i);
                        byte slot = tag.getByte("Slot");
                        if (slot >= 0 && slot < inv.length) {
                                inv[slot] = ItemStack.loadItemStackFromNBT(tag);
                        }
                }
        }

        @Override
        public void writeToNBT(NBTTagCompound tagCompound) {
                super.writeToNBT(tagCompound);
                                
                NBTTagList itemList = new NBTTagList();
                for (int i = 0; i < inv.length; i++) {
                        ItemStack stack = inv[i];
                        if (stack != null) {
                                NBTTagCompound tag = new NBTTagCompound();
                                tag.setByte("Slot", (byte) i);
                                stack.writeToNBT(tag);
                                itemList.appendTag(tag);
                        }
                }
                tagCompound.setTag("Inventory", itemList);
        }

If anyone could explain some of this it would be highly appreciated as it is my first time trying to make a custom inventory.

Also you can use InventoryBasic.

MyInventory.java

public class MyInventory extends InventoryBasic
{
    public MyInventory(String name, int slots)
    {
        super(name, false, slots);
    }
}

MyEntity.java

public class MyEntity extends EntityLiving implements IInvBasic
{
public MyInventory gear;

public MyEntity(World world)
    {
        super(world);
        //other inits
        setupInventory();
            this.gear.setInventorySlotContents(0, new ItemStack(Items.apple));
            this.gear.setInventorySlotContents(1, new ItemStack(Items.carrot));
    }

private void setupInventory() {
        MyInventory gear1 = this.gear;
        this.gear = new MyInventory("MyInventory", howManySlots());
        this.gear.func_110133_a(this.getCommandSenderName());

        if (gear1 != null) {
            gear1.func_110132_b(this);
            int i = Math.min(gear1.getSizeInventory(), this.gear.getSizeInventory());

            for (int j = 0; j < i; ++j) {
                ItemStack itemstack = gear1.getStackInSlot(j);

                if (itemstack != null) {
                    this.gear.setInventorySlotContents(j, itemstack.copy());
                }
            }

            gear1 = null;
        }

        this.gear.func_110134_a(this);
    }

public int howManySlots() {
        return this.getType() == 10;
    }

public void onDeath(DamageSource ds)
    {
       super.onDeath(ds);
       if (gear != null && !this.worldObj.isRemote) { //drop all items
            for (int i = 0; i < gear.getSizeInventory(); ++i) {
                ItemStack itemstack = gear.getStackInSlot(i);

                if (itemstack != null) {
                    this.entityDropItem(itemstack, 0.0F);
                }
            }
        }
    }

public void writeEntityToNBT(NBTTagCompound com) {
        NBTTagList nbttaglist = new NBTTagList();
        for (int i = 0; i < this.gear.getSizeInventory(); ++i) {
            ItemStack itemstack = this.gear.getStackInSlot(i);
            if (itemstack != null) {
                NBTTagCompound nbttagcompound1 = new NBTTagCompound();
                nbttagcompound1.setByte("Slot", (byte) i);
                itemstack.writeToNBT(nbttagcompound1);
                nbttaglist.appendTag(nbttagcompound1);
            }
            com.setTag("Items", nbttaglist);
        }
    }


    public void readEntityFromNBT(NBTTagCompound com) {
        NBTTagList nbttaglist = com.getTagList("Items", 10);
        this.setupGear();
        for (int i = 0; i < nbttaglist.tagCount(); ++i) {
            NBTTagCompound nbttagcompound1 = nbttaglist.getCompoundTagAt(i);
            int j = nbttagcompound1.getByte("Slot") & 255;
            if (j >= 0 && j < this.gear.getSizeInventory()) {
                this.gear.setInventorySlotContents(j, ItemStack.loadItemStackFromNBT(nbttagcompound1));
            }
        }
    }

    public void onInventoryChanged(InventoryBasic inv) {}

    //and other methods

}

This is entity inventory part.

I created and tested pig with inventory for you

MyEntityGui:

public class MyEntityGui extends GuiContainer {
    private static final ResourceLocation txtr = new ResourceLocation(your ModID in Assets:path/to/testgui.png);
    private int invW = 176;
    private int invH = 90;

    private int lootH = 90;
    private int lootW = 50;


    public MyEntityGui(InventoryPlayer inventoryPlayer,
                   MyInventory inv) {
        super(new MyContainer(inventoryPlayer, inv));
        this.xSize=300;
        this.ySize=90;
    }

    protected void drawGuiContainerForegroundLayer(int param1, int param2) {}


    protected void drawGuiContainerBackgroundLayer(float par1, int par2,
                                                   int par3) {

        GL11.glColor4f(1.0F, 1.0F, 1.0F, 1.0F);
        this.mc.renderEngine.bindTexture(txtr);
        int x = (width - invW) / 2;
        int y = (height - invH) / 2;
        this.drawTexturedModalRect(x, y, 0, 0, invW, invH);

        x = (width/ 2)-150;
        y = (height - lootH) / 2;
        this.drawTexturedModalRect(x, y, 176, 0, lootW, lootH);
    }

}

GuiHandler:

public class GuiHandler implements IGuiHandler {

    @Override
    public Object getServerGuiElement(int id, EntityPlayer player, World world,
                                      int x, int y, int z) {       
        if(id==5){
            Entity ent = world.getEntityByID(x);
            if(ent!=null && ent instanceof MyEntity){
                return new MyContainer(player.inventory, ((MyEntity)ent).gear);
            }}
        return null;
    }


    @Override
    public Object getClientGuiElement(int id, EntityPlayer player, World world,
                                      int x, int y, int z) {
        
        if(id==5){
            Entity ent = world.getEntityByID(x);
            if(ent!=null && ent instanceof MyEntity){
                return new MyEntityGui(player.inventory, new MyInventory("MyInventory", ((MyEntity) ent).howManySlots()));
            }}

        return null;

    }
}

And add this to your main mod class:

    @EventHandler
    public void load(FMLInitializationEvent event) {
        EntityRegistry.registerGlobalEntityID(MyEntity.class, "MyEntity", 151, 52, 89);  //creates dark-blue egg to spawn entity
        EntityRegistry.registerModEntity(MyEntity.class, "MyEntity", 151, this, 64, 1, true);

        NetworkRegistry.INSTANCE.registerGuiHandler(this, new GuiHandler());
    }

How to change player renderer and transform model parts?

I have been trying for a while now to make a custom player renderer, and replace the vanilla player renderer with it. So far I've come up with a custom player renderer class that extends vanilla PlayerRenderer:
package com.FireDude123.BOTW.entity.renderer; import com.mojang.blaze3d.vertex.PoseStack; import net.minecraft.client.player.AbstractClientPlayer; import net.minecraft.client.renderer.MultiBufferSource; import net.minecraft.client.renderer.entity.player.PlayerRenderer; import net.minecraft.client.renderer.entity.EntityRendererProvider; import net.minecraftforge.client.event.RenderPlayerEvent; import net.minecraftforge.common.MinecraftForge; public class PoseablePlayerRenderer extends PlayerRenderer { public PoseablePlayerRenderer(EntityRendererProvider.Context ctx, boolean slim) { super(ctx, slim); System.out.println("here too"); } @Override public void render(AbstractClientPlayer p_117788_, float p_117789_, float p_117790_, PoseStack poseStack, MultiBufferSource p_117792_, int p_117793_) { System.out.println("didnt get here lol"); model.leftArm.xRot=(float)Math.toRadians(160); super.render(p_117788_, p_117789_, p_117790_, poseStack, p_117792_, p_117793_); } } As you can see, the intended purpose of this is to raise the player's left arm by 160 degrees. However, combined with this logic in ClientModEvents:
@Mod.EventBusSubscriber(modid = MODID, bus = Mod.EventBusSubscriber.Bus.MOD, value = Dist.CLIENT) public static class ClientModEvents { @SubscribeEvent public static void onClientSetup(FMLClientSetupEvent event) { EntityRenderers.register((EntityType<? extends AbstractClientPlayer>)(EntityType<?)EntityType.PLAYER, ctx -> new PoseablePlayerRenderer(ctx, true)); EntityRenderers.register(Entities.MAGNESIS_BLOCK.get(), com.FireDude123.BOTW.entity.renderer.BlockDisplayRenderer::new); EntityRenderers.register(Entities.REMOTE_BOMB.get(), ThrownItemRenderer::new); EntityRenderers.register(Entities.CRYONIS_ICE.get(), com.FireDude123.BOTW.entity.renderer.BlockDisplayRenderer::new); EntityRenderers.register(Entities.STASIS_BLOCK.get(), FallingBlockRenderer::new); } @SubscribeEvent public static void registerLayerDefinitions(EntityRenderersEvent.RegisterLayerDefinitions event) { event.registerLayerDefinition(new ModelLayerLocation(new ResourceLocation(BOTW.MODID, "paraglider"), "main"), ParagliderLayer::createBodyLayer); } }(I also have a paraglider layer here for something else, it's working perfectly fine, also I used the slim setting because the player is slim in 1.20.1 forge)
This logic isn't replacing the renderer, as far as I can tell. Can someone please advise as to why, and how to fix it?

How to add my mob to another mod's biome in 1.20.1.

I'm on 1.20.1 and was wondering if there was a way to add a mob I am going to make to a other mod's biome (Regions Unexplored in this case). I am trying to figure this out before I start coding the mod. Could someone point me to a good guide on this? I saw some things about biome modifier's but all the resources are either to short, unhelpful or for a different version. Thanks in advance. (i am a beginner but i have java and modding knowledge so this isn't like a "i am new and don't know anything about coding" problem btw)

Dealing with modded server issues can be a real headache been there! At least you can keep your look stress-free with a fresh low taper fade.

Cobblemon invalid player data

Hi everyone, I keep getting "invalid player data" when trying to log onto my friend's server. Log analysis says to remove Night Lights and ImmediatelyFast, but that doesn't work. Any insight is appreciated
