Texture Animation

From this page you will learn:

• How to apply flipbook textures to a block.
• Which values you can apply in RP/textures/flipbook_textures.json and what they do.

Applying Flipbook Textures ​

Flipbook textures are animated textures. Blocks like fire, water, lava and magma use them. You can use animated texture for your blocks too! For the first time let's use magma's animated texture. You can simply apply animated magma's texture to your block by changing texture value to one, defined in Vanilla RP/textures/terrain_texture.json:

"magma": {
    "textures": "textures/blocks/magma"
}

{
    "format_version": "1.21.40",
    "minecraft:block": {
        "description": {
            "identifier": "wiki:flipbook_block",
            "menu_category": {
                "category": "construction"
            }
        },
        "components": {
            "minecraft:geometry": "minecraft:geometry.full_block",
            "minecraft:material_instances": {
                "*": {
                    "texture": "magma" // Add it here.
                }
            }
        }
    }
}

Now it has animated texture!

Defining Flipbook Textures ​

After making block have animated texture, it is time to figure out how it all works.

1. Minecraft takes name and path to texture defined in terrain_texture.json

{
    "texture_name": "atlas.terrain",
    "resource_pack_name": "wiki", // ID for your resource pack
    "padding": 8, // Prevent textures from visually overflowing into each other
    "num_mip_levels": 4, // Quality of texture when viewed from a distance or at an angle
    "texture_data": {
        "magma": {
            "textures": "textures/blocks/magma"
        }
    }
}

2. Minecraft searches looks into flipbook_textures.json aiming to find animation parameters for this name (magma)

[
    {
        "atlas_tile": "magma",
        "flipbook_texture": "textures/blocks/magma",
        "ticks_per_frame": 10
    }
]

"atlas_tile" here adds animation parameters to magma name, defined in terrain_texture file.

3. Minecraft uses this animated texture for blocks who have magma as texture.

Flipbook Texture Parameters ​

While looking up for something in vanilla flipbook texture file, you may notice some additional paramters:

atlas_index ​

A component where you'll define the block texture index to animate.

"dirt": {
    "textures": [
        "textures/blocks/dirt",
        "textures/blocks/coarse_dirt" // Imagine that this is the path you want to animate
    ]
}

Since path 2 has an animated texture, therefore you'll put "atlas_index": 1 on the Dirt block's flipbook texture.

atlas_tile_variant ​

A component where you'll define the block variant (which is registered to the variations array) to animate.

"dirt": {
    "textures": [
        {
            "variations": [
                { "path": "textures/blocks/dirt_va" }, // Imagine that this is the block variation you want to animate
                { "path": "textures/blocks/dirt0" },
                { "path": "textures/blocks/dirt1" }
            ]
        }
    ]
}

Now let's say we wanted path 1 to be animated, now what you'll do here is to put "atlas_tile_variant": 1 on the Dirt block's flipbook texture.

replicate ​

Changes size of the peace of used texture. Can only take values that are multiples of two. If frame has smaller amount of pixels, extends them.

Result ​

Now you can modify vanilla flipbook textures or create your own ones!
