# Block properties
## Visual
### *texture*
Block texture name (name of the file in `textures/blocks/` with no path and extension included, just name)
Texture file must be a **png** image
### *texture-faces*
> [!IMPORTANT]
> Can't be used if `texture` already specified
An array of 6 texture names for block sides.
Example:
```json
"texture-faces": [
"grass_side",
"grass_side",
"dirt",
"grass_top",
"grass_side",
"grass_side"
]
```
### *model*
Block model type from list:
- "block" - default block model
- "none" - invisible block (air)
- "X" - grass model (two crossed sprites)
- "aabb" - model based of block hitbox (complex hitbox will be combined into one). Examples: pipes, bulbs, panels.
### *draw-group*
Integer specifying number of block draw group (render order). Used for semi-transparent blocks.
### *rotation*
Rotation profile (set of available block rotations and behaviour of placing block rotation) from list:
- "none" - no rotation available (default profile)
- "pipe" - wood logs, pipes, pillars
- "pane" - panels, doors, signs
## Lighting
### *emission*
An array of 3 integers - R, G, B of light in range \[0, 15\]
Examples:
- *\[15, 15, 15\]* - white with maximal intensity
- *\[7, 0, 0\]* - dim red light
- *\[0, 0, 0\]* - no emission (default value)
### *light-passing*
Light ignores block if **true**
### *sky-light-passing*
Vertical sky light ray ignores block if **true**. (used for water)
### *shadeless*
Turns off block model shading
## Physics
### *obstacle*
Block is not a physical obstacle if **false**
### *hitbox*
An array of 6 numbers describing an offset an size of a block hitbox.
Array *\[0.25, 0.0, 0.5, 0.75, 0.4, 0.3\]* describes hitbox width:
- 0.75m width (from east to west)
- 0.4m height
- 0.3m length (from south to north)
- offset 0.25m east
- offset 0.0m up
- offset 0.5m north
### *grounded*
Is block may only be set on a solid block and destructs on below block destruction.
### *selectable*
Cursor ray will ignore block if **false**.
### *replaceable*
Is block replaceable. Examples: air, water, grass, flower.
### *breakable*
Is block breakable by mouse click.
## Inventory
### *hidden*
If **true** an item will not be generated for block. **picking-item** must be specified
### *picking-item*
Item will be chosen on MMB click on the block.
Example: block `door:door_open` is hidden, so you need to specify `picking-item: "door:door.item"` to bind it to not hidden `door:door` block item.
### *script-name*
Used to specify block script name (to reuse one script to multiple blocks). Name must not contain `packid:scripts/` and extension. Just name.
### *ui-layout*
Block UI XML layout name. Default: string block id.
Examples for block `containermod:container`:
- default: `containermod:container` (*containermod/layouts/container.xml*)
- if `containermod:randombox` specified: (*containermod/layouts/randombox.xml*)
### *inventory-size*
Number of block inventory slots. Default - 0 (no inventory).
## Extended blocks
### *size*
Array of three integers. Default value is `[1, 1, 1]`.
