Isn’t start method supposed to be called each time the game object is enabled?
Indeed. The method simply consists of reference.Start(); as you can call it like any other function. For example using gjf’s idea
function OnEnable()
{
Start();
}
In the past I have simply invoked it the line after enabling, from my remote object, using GetComponent.
RTFM Unity - Scripting API: MonoBehaviour.Start()
Start is called exactly once in the lifetime of the script
