Item Info

Look up the static metadata baked into the client for any block id. Backed by the live ConfigData table when present (full flags + collision), with a fallback to the bundled block_types.json so scripts always get at least an id + name even before any bot has connected.

local item = getInfo(1)   -- 1 = Solid Block

item.id          -- block type
item.name        -- display name
item.flags       -- bitfield: 0x1 untradeable, 0x2 trashable
item.collision   -- 0x0 none, 0x1 collidable, 0x2 oneway, 0x4 hot, 0x8 death

Lookups

getInfo(id)

Field	Type
Signature	(id: number) → ItemInfo?
Returns	ItemInfo? — nil when neither the live ConfigData table nor the fallback catalog has the id
Async	no

local info = getInfo(9)
if info then
    print(info.name)   -- "Obsidian"
end

getInfos()

Field	Type
Signature	() → {ItemInfo}
Returns	{ItemInfo} — 1-indexed list of every block the runtime knows about
Async	no

Source priority: ConfigData (live, full flags) → bundled block_types.json (fallback, id + name only). Returns an empty table when neither has populated yet.

for _, item in pairs(getInfos()) do
  -- ...
end

ItemInfo fields

Field	Type	Notes
id	number	Block id (matches InventoryItem.id and world:findTiles(blockType)).
name	string	Display name. Falls back to "#<id>" — never nil.
flags	number	Bitmask. 0 when ConfigData hasn't arrived.
collision	number	Bitmask. 0 when ConfigData hasn't arrived.

flags bits

Bit	Meaning
0x1	untradeable (player can't list / send via chat)
0x2	trashable (default for every block — rarely cleared)

collision bits

Bit	Meaning
0x0	no collider
0x1	collidable (solid)
0x2	one-way (platform — pass from below, block from above)
0x4	hot (damage on contact, e.g. fire)
0x8	death (instant-kill, e.g. spike, lava)

Combine via bitwise AND:

local UNTRADEABLE = 0x1
if bit32.band(info.flags, UNTRADEABLE) ~= 0 then
    print(info.name, "is untradeable")
end
