Workspaceクラス

クラスサービス（game:GetService("Workspace")で取り出す）Instance.newでは作れない日本語解説あり

ひとことで言うと

ゲームの世界そのものを表すサービスです。Workspaceの中に入れたパーツやモデルが、ゲームの画面に表示されます。スクリプトからは workspace と書いて使えます。

公式の説明（英語）：Workspace houses 3D objects which are rendered to the 3D world. Objects not descending from it will not be rendered or physically interact with the world.

使用例

光線（レイキャスト）で地面を調べる

Script置く場所：ServerScriptService

local origin = Vector3.new(0, 50, 0)
local direction = Vector3.new(0, -100, 0)

local params = RaycastParams.new()
params.FilterType = Enum.RaycastFilterType.Exclude

local result = workspace:Raycast(origin, direction, params)
if result then
	print("当たったもの：" .. result.Instance.Name, result.Position)
end

スクリプトは、Luauの型チェック（luau-lsp）で確認しています。
