Struct SignItem 

pub struct SignItem {
    _standing_block: BlockRef,
    _wall_block: BlockRef,
    _attachment_direction: Direction,
    inner: StandingAndWallBlockItem,
}

Behavior for sign items that place sign blocks and open the editor.

In vanilla, SignItem extends StandingAndWallBlockItem and only overrides updateCustomBlockEntityTag to open the sign editor after placement.

The _standing_block, _wall_block, and _attachment_direction fields are read by the build script via #[json_arg] to generate constructor calls from classes.json. The actual values are forwarded into inner — the fields themselves are not used at runtime.

Fields

_standing_block: BlockRef

_wall_block: BlockRef

_attachment_direction: Direction

inner: StandingAndWallBlockItem

Placement logic delegate (vanilla: SignItem extends StandingAndWallBlockItem).

Implementations

impl SignItem

pub const fn new( standing_block: BlockRef, wall_block: BlockRef, attachment_direction: Direction, ) -> Self

Creates a new sign item behavior for the given sign blocks.

Trait Implementations

impl ItemBehavior for SignItem
