GetComponent(type: string): Component;
Component GetComponent(string type);
def GetComponent(type as string) as 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 ();
