[1.12][Solved] How to change an item texture based on the amount in the stack

Posted August 23, 20196 yr

Hi!

I'm trying to create a shard for one of my items where you cut it and it gives you it's shard's, I want the texture to change based on the amount in the stack, for example, if the ItemStack limit was 2 then if you held there was only 1 in the stack then the texture would show 1 shard but if there was 2 in the texture would change to show 2 shards.

What code do I have to use to make different variants for the same item and how do I get the item to change variants?

Edit: Nevermind I figured out how!

Here is how I did it

In my common proxy, I added

public void registerItemVariant(Item item, ItemMeshDefinition meshDefinition, ModelResourceLocation... names) {}

and in my client proxy, I added

@Override
public void registerItemVariantRenderer(Item item, ItemMeshDefinition meshDefinition, ModelResourceLocation... names) {
   	ModelBakery.registerItemVariants(item, names);
    ModelLoader.setCustomMeshDefinition(item, meshDefinition);
}

Next, I created a new class called ItemMeshDefinitionHandler and did this

public class ItemMeshDefinitionHandler implements ItemMeshDefinition {

    @Override
    public ModelResourceLocation getModelLocation(ItemStack stack) {
        if(stack.getItem() == ItemInit.DIAMOND_SHARD) {
            if(stack.getCount() == 1) {
                return new ModelResourceLocation(stack.getItem().getRegistryName() + "_1", "inventory");
            } else if (stack.getCount() == 2) {
                return new ModelResourceLocation(stack.getItem().getRegistryName() + "_2", "inventory");
            } else  {
                return new ModelResourceLocation(stack.getItem().getRegistryName() + "_2", "inventory");
            }
        } else if(stack.getItem() == ItemInit.COAL_SHARD) {
            if(stack.getCount() == 1) {
                return new ModelResourceLocation(stack.getItem().getRegistryName() + "_1", "inventory");
            } else if (stack.getCount() == 2) {
                return new ModelResourceLocation(stack.getItem().getRegistryName() + "_2", "inventory");
            } else  {
                return new ModelResourceLocation(stack.getItem().getRegistryName() + "_2", "inventory");
            }
        }        
        
        return null;
    }

}

Then in a new class named ItemShard and extended my ItemBase class (In my ItemBase class it implements IHasModel) and did this

public class ItemShard extends ItemBase {
    
    public String name;
    
    public ItemShard(String name, CreativeTabs creativeTab) {
        super(name, creativeTab);
        this.name = name;
        setMaxStackSize(8);
    }
    
    @Override
    public void registerModels() {
        Main.proxy.registerItemVariantRenderer(this, new ItemMeshDefinitionHandler(), new ModelResourceLocation(Reference.MOD_ID + ":" + name + "_1", "inventory"), new ModelResourceLocation(Reference.MOD_ID + ":" + name + "_2", "inventory"));
        
    }
}

Then finally I added the item to my ItemInit

public static final Item DIAMOND_SHARD = new ItemShard("diamond_shard", Main.CreativeTab);

            }
        }        
        
        return null;
    }

}

You might want to use string concatenation instead of the large bulk of ifs.

Some tips:

Spoiler

Modder Support:

Spoiler

1. Do not follow tutorials on YouTube, especially TechnoVision (previously called Loremaster) and HarryTalks, due to their promotion of bad practice and usage of outdated code.

2. Always post your code.

3. Never copy and paste code. You won't learn anything from doing that.

Programming via Eclipse's hotfixes will get you nowhere

5. Learn to use your IDE, especially the debugger.

The "picture that's worth 1000 words" only works if there's an obvious problem or a freehand red circle around it.

Support & Bug Reports:

Spoiler

1. Read the EAQ before asking for help. Remember to provide the appropriate log(s).

2. Versions below 1.11 are no longer supported due to their age. Update to a modern version of Minecraft to receive support.

return new ModelResourceLocation(stack.getItem().getRegistryName() + "_" + Math.min(stack.getCount(),3), "inventory");

Apparently I'm a complete and utter jerk and come to this forum just like to make fun of people, be confrontational, and make your personal life miserable. If you think this is the case, JUST REPORT ME. Otherwise you're just going to get reported when you reply to my posts and point it out, because odds are, I was trying to be nice.

DO NOT PM ME WITH PROBLEMS. No help will be given.

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

You can add mob spawns using Forge's Biome Modifiers feature. I won't go into details on how to use a data generator for them, but here's a simple example:
{ "type": "forge:add_spawns", // Required "biomes": "#namespace:biome_tag", // Accepts a biome id, [list of biome ids], or #namespace:biome_tag "spawners": { "type": "namespace:entity_type", // Type of mob to spawn "weight": 100, // int, spawn weighting "minCount": 1, // int, minimum pack size "maxCount": 4 // int, maximum pack size } }This JSON file would go somewhere like this: data/modid/forge/biome_modifier/your_biome_modifier.json

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
