FindFirstChild (Method)

FindFirstChild( string name, bool recursive = false )
Returns	Instance
Description:	Returns the first child found with a name of name. Returns nil if no such child exists. If the optional recursive argument is true, will recursively descend the hierarchy while searching rather than only searching the immediate object.
Member of:	Instance

Example

This looks in the Workspace for an object named "Brick". If found, it changes its name to "Foo":

local found = Workspace:FindFirstChild("Brick") if found then

 found.Name = "Foo"

end

Recursive

The recursive argument is optional. If given, recursive sets whether the function should look inside of objects in the calling object, as well as the calling object. If not given, the default is false.

For example, if there is a part in the Workspace called "Part".

Example

This will find the part.

local part = game:FindFirstChild("Part", true)

Example

These two solutions will not.

local part = game:FindFirstChild("Part", false)
local part = game:FindFirstChild("Part")
