GetComponent function description

function GetComponent (type : Type) : Component

Description

Returns the component of Type type if the game object has one attached, null if it doesn't.

C# users can use a generic version.

// Equivalent to: Transform curTransform = transform;
var curTransform : Transform;
curTransform = GetComponent (Transform);

// You can access script components in the same way as other components.
function Start () {
var someScript : ExampleScript;
someScript = GetComponent (ExampleScript);
someScript.DoSomething ();
}

function GetComponent (type : string) : Component

Description

Returns the component with name type if the game object has one attached, null if it doesn't.

It is better to use GetComponent with a Type instead of a string for performance reasons. Sometimes you might not be able to get to the type however, for example when trying to access a C# script from Javascript. In that case you can simply access the component by name instead of type. Example:

// To access public variables and functions
// in another script attached to the same game object.
var script : ScriptName;
script = GetComponent("ScriptName");
script.DoSomething ();
