First matching ancestor, or nil.

Syntax

:FindFirstAncestorOfClass(class: any) -> any

Parameters

Parameter	Type	Description
`class`	`any`	The class value used by the call.

Returns

Type	Description
`any`	The value produced by the call.

Description

FindFirstAncestorOfClass is part of the Instances library. Instances are live proxies backed by game memory. Property reads and method calls go through Roblox's own objects.

The call is read-only: it resolves the current value when invoked and does not change the underlying state.

The aliases :FindFirstAncestorWhichIsA(class) resolve to the same implementation.

Example

local part = workspace:FindFirstChildWhichIsA("BasePart")
if part then
    print(part:FindFirstAncestorOfClass("Model"))
    print(part:FindFirstAncestorWhichIsA("Model"))
end

Aliases: :FindFirstAncestorWhichIsA(class).
Instance proxies are backed by live game memory.
