How to add custom signs - Jurassic Saga

Info

The last update on this page was on: 28th April 2026

In this guide we'll cover how to:

Adding custom paddock sign
Adding custom facility sign

Folder Structure

You could use a plain datapack + resource-pack, but for simplicity we'll use a JS-addon.

[addon_name]/
    addon_data/
    data/
        data/
            [addon_name]/
        pack.mcmeta
    resources/
        assets/
            [addon_name]/
        pack.mcmeta

Warning

I won't reference pack.mcmeta anymore from this point forwards, it should still be there.

We'll not use the addon_data/ folder, but it needs to be there for the parser

Inside the data folder we'll start adding the necessary folders.

[addon_name]/
    addon_data/
    data/
        data/
            [addon_name]/
                paddock_signs/
                    custom/
                        [paddock_sign_name].json
                facility_signs/
                    custom/
                        [facility_sign_name].json
    resources/

We're using the custom folder inside the data to avoid confusion

Paddock Sign Colors

Value	Color
`0`	`BLUE`
`1`	`GREEN`
`2`	`PURPLE`
`3`	`RED`
`4`	`WHITE`
`5`	`YELLOW`
`6`	`FACILITY` (Pure White)

{
    "name": "[Facility Sign Name]",
    "location": "[addon_name]:[facility_sign_name]"
}

Warning

"name": is going to get changed to

"translation": "[addon_name].[facility_sign_name]"

in the near future.

If you want your future signs to be compatible, feel free to add it early

The name here is the display name in the designated items

That's all for data, lets move on to resources.

Resources

[addon_name]/
    addon_data/
    data/
    resources/
        [addon_name]/
            models/
                signs/

We're going to add the JSON files for the signs first!

Texture name has to be equal to the location set in the data files.

...
    models/
        signs/
            facility/
                custom/
                    [facility_sign_name].json
            paddock/
                custom/
                    [paddock_sign_name].json

{
    "parent": "minecraft:item/generated",
    "textures": {
        "layer0": "[addon_name]:block/facility_sign/[facility_sign_name]"
    }
}

Now let's add the textures!

[addon_name]/
    addon_data/
    data/
    resources/
        [addon_name]/
            models/
            textures/
                block/
                    facility_sign/
                        [facility_sign_name].png
                    paddock_sign/
                        [paddock_sign_name].png

Info

If you are wondering why this is different from New Species, it's because this has been registered as an custom sign!

The paddock signs still needs one extra thing! (You can skip this for the facility sign)

Let's add the coin.

[addon_name]/
    addon_data/
    data/
    resources/
        [addon_name]/
            models/
            textures/
                block/
                gui/
                    icon/
                        [paddock_sign_name].png

And that should be all for the signs!

Translation file

Warning

This hasn't been implemented yet, but feel free to add it in advance to make sure your maintain compatibility.

Let's add the default language file:

[addon_name]/
    addon_data/
    data/
    resources/
        [addon_name]/
            models/
            textures/
            lang/
                en_us.json

en_us.json is the main JSON file used by Minecraft.

Inside this file:

{
    "[addon_name].[facility_sign_name]": "[Facility Sign Name]",
    "[addon_name].[paddock_sign_name]": "[Paddock Sign Name]"
}

That should be all!
