Struct CraftingGrid 

pub struct CraftingGrid {
    pub slots: [Slot; 9],
    pub grid_size: u8,
    pub output: Slot,
}

Tracks the contents of a player’s crafting grid.

Used for both the 2x2 inventory crafting grid and the 3x3 crafting table grid. The grid_size field determines which slots are active: for a 2x2 grid, only slots[0..4] are used; for a 3x3 grid, all nine slots are active.

The output slot holds the result computed by the recipe matching system. It is read-only from the player’s perspective — the server sets it when the grid contents change.

Fields

slots: [Slot; 9]

The 9 crafting input slots. For a 2x2 grid, only indices 0-3 are used; indices 4-8 remain empty.

grid_size: u8

Grid dimension: 2 for the player inventory grid, 3 for a crafting table.

output: Slot

The crafting output slot, set by the recipe matching system.

Implementations

impl CraftingGrid

pub fn empty() -> Self

Creates an empty 2x2 crafting grid with no items.

All nine slot positions are initialized to empty, and the output slot is empty. This is the default state for a player who has not interacted with any crafting interface.

pub fn clear(&mut self)

Clears all input slots and the output slot.

The grid size is preserved — a 3x3 grid remains 3x3 after clearing. This is used when a player closes a crafting table window (items are returned to inventory, grid is reset).
