getcallbackvalue

Reads an instance callback.

Syntax

getcallbackvalue(instance: Instance, property: string) -> any

Parameters

Parameter	Type	Description
`instance`	`Instance`	The Instance to read from or modify.
`property`	`string`	The property name to access.

Returns

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

Description

getcallbackvalue is part of the Reflection library. Reflection walks Roblox's property metadata to read or write values that are normally hidden from scripts.

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

The aliases getcallbackmember, get_callback_value, get_callback_member resolve to the same implementation.

Example

print(getcallbackvalue(workspace, "ChildAdded"))

Notes

Aliases: getcallbackmember, get_callback_value, get_callback_member.
Reflection reads live property metadata; hidden-property writes can desynchronise client state.
