BindableFunction

Show deprecated

A BindableFunction is a Roblox object that allows you to give access to functions to external scripts. Functions put in BindableFunctions will not be replicated, therefore making it impossible to use these objects to pass functions between scripts. Functions are invoked through BindableFunction/Invoke, which calls BindableFunction/OnInvoke.

Returns the first ancestor of the Instance for whom Instance/IsA returns true for the given className.
Instance

FindFirstChild ( string name , bool recursive )

Returns the first child of the Instance found with the given name.
Instance

FindFirstChildOfClass ( string className )

Returns the first child of the Instance whose Instance/ClassName|ClassName is equal to the given className.

Objects

GetChildren ( )

Returns an array containing all of the Instance's children.
string

GetDebugId ( int scopeLength )

[NotBrowsable]

Returns a coded string of the Instances DebugId used internally by Roblox.
Array

bool

IsA ( string className )

[CustomLuaState]

Returns true if an Instance's class matches or inherits from a given class
bool

IsAncestorOf ( Instance descendant )

Returns true if an Instance is an ancestor of the given descendant.
bool

IsDescendantOf ( Instance ancestor )

Returns true if an Instance is a descendant of the given ancestor.

Sets the object’s Parent to nil, and does the same for all its descendants.
void

SetAttribute ( string attribute , Variant value )

Instance

WaitForChild ( string childName , double timeOut )

[CustomLuaState] [CanYield]

Code Samples

BindableFunction Addition

This code sample sets the OnInvoke callback of the parent BindableFunction to a function that returns the sum of two numbers. Test this code sample by pasting this code inside a Script within a BindableFunction. You’ll then be able to use Invoke on the BindableFunction from other scripts.

BindableFunction Valid Values

This code sample shows the kinds of values that can be sent to and from BindableFunctions via Invoke/OnInvoke. Test this code by placing a Script within a BindableFunction inside the Workspace or ServerScriptService. It will raise errors on the values that cannot be sent.
