Block Properties

Block properties share the same properties as items

All properties (excluding the shared item and decoration properties):

Example

{
  "properties": {
    "blockBase": "minecraft:stone",
    "requiresTool": true,
    "explosionResistance": 10,
    "destroyTime": 5,
    "redstoneConductor": false,
    "lightEmission": 0,
    "lootTable": "minecraft:block/dirt",
    "sounds": {
      "volume": 1,
      "pitch": 0.2,
      "break": "minecraft:entity.allay.hurt",
      "step": "minecraft:entity.sniffer.hurt",
      "place": "minecraft:entity.shulker.hurt",
      "hit": "minecraft:entity.axolotl.hurt",
      "fall": "minecraft:item.bone_meal.use"
    }
  }
}

blockBase:

Specifies the base block used for sounds and the block color on maps.

Defaults to minecraft:stone

requiresTool:

Boolean (true/false) indicating whether the block requires a specific tool to be harvested.

Defaults to true

explosionResistance:

Number indicating the block's resistance to explosions.

Defaults to 0

destroyTime:

Resistance of the block/the time required to destroy the block.

The destroyTime is used as explosionResistance if explosionResistance is not explicitly specified.

For indestructible blocks use a destroyTime of -1.

Defaults to 0

redstoneConductor:

Boolean (true/false) indicating whether the block can conduct redstone signals.

Tip

All fields of this property can be mapped to a block-state.

The value of this property can be mapped to a blockstate like this:

Example

{
  "properties": {
    "redstoneConductor": {
      "powerlevel=0": true,
      "powerlevel=1": false,
      // etc.
    }
  }
}

Defaults to true

lightEmission:

Light level this block emits.

Tip

All fields of this property can be mapped to a block-state.

The value of this property can be mapped to a blockstate like this:

Example

{
  "properties": {
    "lightEmission": {
      "powerlevel=0": 0,
      "powerlevel=1": 1,
      // etc
    }
  }
}

Defaults to 0

transparent:

Flag indicating whether the block is transparent. Transparent blocks don't block light.

Defaults to false

isSuffocating

Flag whether the block causes suffocation damage. The default is unset.

jumpFactor

Allows to change the bounciness or stickiness of the block. Set to a value below 1 to make the block act like honey, and above 1 to make it bouncy.

Defaults to 1.0

allowsSpawning:

Flag indicating whether mobs can spawn on this block.

Defaults to false

replaceable:

Flag indicating whether this block can be replaced by another block when placing a new block (e.g., grass can be replaced when placing a solid block). Defaults to false

collision:

Flag indicating whether the block has collision Defaults to true

solid:

Flag indicating whether the block gets flushed away with water.

Defaults to true

pushReaction:

Specifies how the block reacts to being pushed by a piston. Possible values include normal, destroy, block

Defaults to normal

lootTable:

Allows to override the default loot table

Example: minecraft:blocks/dirt

Defaults to <namespace>:blocks/<blockname>.

So for a block "mynamespace:myblock", the default would be mynamespace:blocks/myblock

sounds

Allows to specify a set of sounds and the volume/pitch for them.

All sounds, including step sounds, will be played serverside! Even for some vanilla blocks, since filament sets the vanilla sounds to an empty list, as a lot of blocks share the same sounds (noteblocks and all wooden blocks use the same wood sounds for example)

This might affect performance a bit, for this reason there is a config option in config/filament.json called "sound_module" to enable/disable the server-side block sounds.

Example

{
  "properties": {
    "sounds": {
      "volume": 1,
      "pitch": 0.2,
      "break": "minecraft:entity.allay.hurt", // sound when broken
      "step": "minecraft:entity.sniffer.hurt", // sound when stepped on
      "place": "minecraft:entity.shulker.hurt", // sound when placed
      "hit": "minecraft:entity.axolotl.hurt", // sound when hit/being mined
      "fall": "minecraft:item.bone_meal.use" // sound when an entity falls on the block
    }
  }
}
