How would I get my character to move to the right of the screen automatically and stop once it reaches an NPC, then a text bubble appears, making the camera zoom in on it and the player has to use their mouse to select the Yes or No button after the decision is made, the player moves off the screen to the next floor, which is the same concept, the player walks up to an NPC and a text bubble appears. Please help me 
If collider hit (or code logic = true)? If yes then move object (set transform moving/walk animation etc) to waypoint, something like that?
