Caching

[SerializeField] float timeToWait = 2f;
MeshRenderer renderer; // renderer is cached
 
void Start()
{
	renderer = GetComponent<MeshRenderer>();
	renderer.enabled = false;
}

• Caching
  • A technique of storing frequently used data/info in memory, so it can be easily accessed
• when you use GetComponent<T>(), you’re fetching a component that is attached to the same GameObject that the script is attached to
  • If the GameObject has the component, it returns a reference to it.
  • If it doesn’t, it returns null
