Snow! Real Magic! ⛄

A simple tweak mod that enriches the vanilla snow layer's behavior.

Features

With this mod you can:

• Place snow and a fence/wall/tall grass in the same block!
• Enjoy snow-covered slabs, stairs, walls, fences and fence gates — they can also generate naturally in the world!
• Watch snow layers fall like sand. Falling snow that touches a water source turns into ice
• See snow layers pile up during a snowstorm (thunder) — or during any snowfall
• Walk on snow layers with a thinner collision box, just like in Bedrock Edition
• Land softly on snow: the more layers, the less fall damage
• Place blocks into snow directly — snow is always replaceable as long as it is not a full layer
• Right-click snow with a shovel, or sneak + right-click with an empty hand, to scrape off a snowball (consumes one layer)
• Right-click a snow-covered block with both hands empty to toggle its fancy snow overlay
• Make snow never melt, make it melt in warm biomes, or let it melt away naturally over time
• And more!

All features can be toggled in the config.

Two game rules, snowrealmagic:blizzardStrength (1–8, max layers) and snowrealmagic:blizzardFrequency (N/10000 per tick per chunk), make snow blocks fall from the sky. Have fun!

Customization

<details> <summary>Tweaking behavior with block tags</summary>

Datapacks can change which blocks interact with snow by adding to the mod's block tags. To append entries, create the file under the snowrealmagic namespace in your datapack, e.g. data/snowrealmagic/tags/block/containables.json:

(Also see Editing tags using KubeJS)

{
	"values": [
		"mymod:my_flower",
		{
			"id": "#mymod:my_pebbles",
			"required": false
		}
	]
}

Available tags:

• containables: Blocks that snow can be placed into, turning them snow-covered. (Default: plants, offset_y, expand_model and #c:chains)
• not_containables: Blacklist. Blocks here can never contain snow, even if they are in containables. (Default: #minecraft:leaves)
• plants: Plants that become snowy plants when snow covers them. Compared to #containables, it will be able to be detected by shaderpacks to make them swing, but as far as I know, no shaderpacks support this yet. (Default: dead bush, flowers, saplings, mushrooms, etc.)
• entity_inside: Snow-covered blocks that keep their touch effects, e.g. wither rose damage. (Default: wither rose, sweet berry bush)
• animate_tick: Snow-covered blocks that keep their ambient particles, e.g. firefly bush. (Default: wither rose, open eyeblossom, dry grass, firefly bush)
• offset_y: Flat blocks that are rendered slightly raised when snow-covered, to avoid z-fighting with the snow layer. (Default: pebbles, twigs and similar decorations from supported mods)
• expand_model: Blocks whose model should be treated as a full cube when snow-covered. Used for compat with mods like vertical slabs.
• cannot_accumulate_on: Snow will not naturally accumulate on top of these blocks. (Default: hay block, slabs)

<details> <summary>Custom snowy models with .mcmeta</summary>

Resource packs can change how a block looks when it is snow-covered. Add a .json.mcmeta file next to the block's model file with an srm section pointing to the model to use instead. For example, assets/minecraft/models/block/dandelion.json.mcmeta:

{
	"srm": {
		"model": "mypack:block/snowy_dandelion"
	}
}

The snowy model is a regular block model. For cross-shaped foliage you can parent the built-in template, which renders the plant together with a snow overlay:

{
	"parent": "snowrealmagic:block/snowy_cross",
	"textures": {
		"cross": "block/dandelion",
		"snow": "mypack:block/snowy_dandelion"
	}
}

For double-height plants such as tall grass, put the mcmeta on the top-half model and add an overrideBlocks list with the block ID, so the upper half also renders snowy:

{
	"srm": {
		"model": "mypack:block/snowy_tall_grass_top",
		"overrideBlocks": ["minecraft:tall_grass"]
	}
}

This feature requires the client config snowVariants to be enabled (it is by default).

Uninstalling

Before removing the mod, you may want to enable snow-cover.restoreOriginalBlocks in the config. Snow-covered blocks will then be restored to their original blocks as chunks load, leaving no modded blocks behind.
