Correct me if I am wrong: you would like that a cut scene or something happens when the player arrive to certain point in the world?
If this is correct you can create a box with a collider and use a OnTriggerEnter method that will let you understand when the player triggers with the box (that in your game would be: when the player arrives at a certain point)
@anflex : You missed the part where I said I’m not actually going to use this for a cut scene, but used it for an example. eg, to zoom in on the players face etc.
