1.11 onItemUse -> need access to stack and position.

Posted December 10, 20168 yr

In 1.10 I stored item information in the onItemUse function to nbt to save the progress of a certain action.

 @NotNull
    @Override
    public EnumActionResult onItemUse(
                                       final ItemStack stack,
                                       final EntityPlayer playerIn,
                                       final World worldIn,
                                       final BlockPos pos,
                                       final EnumHand hand,
                                       final EnumFacing facing,
                                       final float hitX,
                                       final float hitY,
                                       final float hitZ)
    {
        if (!stack.hasTagCompound())
        {
            stack.setTagCompound(new NBTTagCompound());
        }
        final NBTTagCompound compound = stack.getTagCompound();

        if (!compound.hasKey("pos1"))
        {
            BlockPosUtil.writeToNBT(compound, "pos1", pos);
            if (worldIn.isRemote)
            {
                LanguageHandler.sendPlayerLocalizedMessage(playerIn, "item.scepterSteel.point");
            }
            return EnumActionResult.SUCCESS;
        }
        else if (!compound.hasKey("pos2"))
        {
            @NotNull final BlockPos pos1 = BlockPosUtil.readFromNBT(compound, "pos1");
            @NotNull final BlockPos pos2 = pos;
            if (pos2.distanceSq(pos1) > 0)
            {
                BlockPosUtil.writeToNBT(compound, "pos2", pos2);
                if (worldIn.isRemote)
                {
                    LanguageHandler.sendPlayerLocalizedMessage(playerIn, "item.scepterSteel.point2");
                }
                return EnumActionResult.SUCCESS;
            }
            if (worldIn.isRemote)
            {
                LanguageHandler.sendPlayerLocalizedMessage(playerIn, "item.scepterSteel.samePoint");
            }
            return EnumActionResult.FAIL;
        }
        else
        {
            @NotNull final BlockPos pos1 = BlockPosUtil.readFromNBT(compound, "pos1");
            @NotNull final BlockPos pos2 = BlockPosUtil.readFromNBT(compound, "pos2");
            if (!worldIn.isRemote)
            {
                saveStructure(worldIn, pos1, pos2, playerIn);
            }
            compound.removeTag("pos1");
            compound.removeTag("pos2");
            return EnumActionResult.SUCCESS;
        }
    }

In 1.10 though, the onItemUse does not offer the itemStack and the position variable at the same time.

I tried this but it won't work:

@NotNull
    @Override
    public EnumActionResult onItemUse(
                                       final EntityPlayer playerIn,
                                       final World worldIn,
                                       final BlockPos pos,
                                       final EnumHand hand,
                                       final EnumFacing facing,
                                       final float hitX,
                                       final float hitY,
                                       final float hitZ)
    {
        ItemStack stack = playerIn.getActiveItemStack();
        if (!stack.hasTagCompound())
        {
            stack.setTagCompound(new NBTTagCompound());
        }
        final NBTTagCompound compound = stack.getTagCompound();

        if (!compound.hasKey("pos1"))
        {
            BlockPosUtil.writeToNBT(compound, "pos1", pos);
            if (worldIn.isRemote)
            {
                LanguageHandler.sendPlayerLocalizedMessage(playerIn, "item.scepterSteel.point");
            }
            return EnumActionResult.SUCCESS;
        }
        else if (!compound.hasKey("pos2"))
        {
            @NotNull final BlockPos pos1 = BlockPosUtil.readFromNBT(compound, "pos1");
            @NotNull final BlockPos pos2 = pos;
            if (pos2.distanceSq(pos1) > 0)
            {
                BlockPosUtil.writeToNBT(compound, "pos2", pos2);
                if (worldIn.isRemote)
                {
                    LanguageHandler.sendPlayerLocalizedMessage(playerIn, "item.scepterSteel.point2");
                }
                return EnumActionResult.SUCCESS;
            }
            if (worldIn.isRemote)
            {
                LanguageHandler.sendPlayerLocalizedMessage(playerIn, "item.scepterSteel.samePoint");
            }
            return EnumActionResult.FAIL;
        }
        else
        {
            @NotNull final BlockPos pos1 = BlockPosUtil.readFromNBT(compound, "pos1");
            @NotNull final BlockPos pos2 = BlockPosUtil.readFromNBT(compound, "pos2");
            if (!worldIn.isRemote)
            {
                saveStructure(worldIn, pos1, pos2, playerIn);
            }
            compound.removeTag("pos1");
            compound.removeTag("pos2");
            return EnumActionResult.SUCCESS;
        }
    }

What can I do to make it work again?

ItemStack argument was removed. All you need to do is getHeldItem(hand)

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)

Help with file conversion

Many Forge users seek help with file conversions. Similarly, managing your health can benefit from structured tools like the https://wellness-app.com/calculator/fasting-calculator/ and a free intermittent fasting calculator. These tools help you plan and personalize your fasting and eating windows based on your lifestyle and goals. By entering your preferred fasting duration and meal times, you receive a tailored schedule that makes intermittent fasting easier to follow. Just as mastering file conversions improves modding success, using a fasting calculator brings clarity and structure to your health routine, supporting better results over time.

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

Bad pathfinding for big mobs (1.21.1)

I've struggled with this for way too long now, so I have decided to ask for some assistance here because there is almost no information about this online.

I made a hostile mob and I built it like this:
public static final Supplier<EntityType<Bunyip>> BUNYIP = ENTITY_TYPES.register("bunyip" , () -> EntityType.Builder. of(Bunyip::new, MobCategory.MONSTER).sized(3f, 2.5f).eyeHeight(1.75f).build("bunyip"));

However, I have discovered that a BoundingBox of 3 is too big for the vanilla pathfinding to work well. In fact, anything bigger than a block will not work well. This is especially noticeable when having it chase a player in a negative X and/or negative Z direction. The mob starts spinning, walking backwards, walking diagonally, etc.

I am using the Goal system:
protected void registerGoals() { super.registerGoals(); this.goalSelector.addGoal(1, new MeleeAttackGoal(this, 1.25, true)); this.targetSelector.addGoal(2, new NearestAttackableTargetGoal<>(this, Player.class, true, true)); }

This does not seem to be a me issue as the ravager, one of the biggest vanilla mobs, also struggles with proper pathfinding. I am a bit familiar with how Minecraft's pathfinding works, but not enough to make a pathfinding system from scratch (or at least not in a reasonable amount of time). Is there any way to fix this with some tweaks or will I have to make a custom pathfinding system?
