🎨 Custom Megaphone Texture

VCM uses Minecraft's Custom Model Data system to apply a custom texture to the megaphone item. The default value is 7641 and the base item is CARROT_ON_A_STICK.

Step-by-step guide

1. Prepare your texture

Create a 32×32 (or 64×64) PNG image for the megaphone. Name it, for example, megaphone.png.

2. Set up a resource pack structure

my_resourcepack/
├── pack.mcmeta
└── assets/
    └── minecraft/
        ├── models/
        │   └── item/
        │       ├── carrot_on_a_stick.json   ← override file
        │       └── megaphone.json           ← your model
        └── textures/
            └── item/
                └── megaphone.png            ← your texture

3. Create pack.mcmeta

{
  "pack": {
    "pack_format": 46,
    "description": "VCM Megaphone texture"
  }
}

4. Create megaphone.json (a simple flat item model)

{
  "parent": "item/handheld",
  "textures": {
    "layer0": "item/megaphone"
  }
}

5. Override carrot_on_a_stick.json

Add a custom_model_data override that points to your model when the value matches what is set in config.yml (default 7641):

{
  "parent": "item/handheld",
  "textures": {
    "layer0": "item/carrot_on_a_stick"
  },
  "overrides": [
    {
      "predicate": { "custom_model_data": 7641 },
      "model": "item/megaphone"
    }
  ]
}

6. Zip and apply

Compress the my_resourcepack/ folder into a .zip file and put it on your server (via server.properties → resource-pack) or distribute it to players manually.

7. Match the value in config

Make sure custom-model-data in config.yml matches the predicate value you used in the model override:

megaphone:
  custom-model-data: 7641   # Must match the override predicate

Tip: If you want to use a different base item (e.g. STICK), change megaphone.material in config.yml and create the override file for that item instead.
