compareinstances

Checks whether a and b are the same Roblox Instance.

compareinstances(a: Instance, b: Instance): boolean

Calling cloneref on an Instance gives you a separate Lua reference. Roblox treats both as the same Instance, but using the == operator compares the objects themselves - so original == cloneref(original) will return false. compareinstances checks the Roblox Instances behind them instead.

Most commonly used after cloneref to confirm a clone and its original are the same Roblox Instance.

Parameters

Parameter	Type	Description
a	Instance	The first instance to compare.

Example 1

local same = compareinstances(game:GetService("Players"), game:GetService("Players"))

Bypasses standard Lua == reference inequality for cloned references.
