function Update(){ if (Input.GetButtonUp("Action")&& isPlayerVisible){ // make player invisible and still standing player.gameObject.SetActiveRecursively(false); player.gameObject.active = false; // parent player to Exit Point player.parent = exitPoint.transform; player.transform.localPosition = Vector3(-1.5,0,0); // parent PlayerParent to car exitPoint.parent = car.transform; exitPoint.transform.localPosition = Vector3(-0.5,0,0); // Enable Car as controllabe object GameObject.Find("car").GetComponent("DrivingScript").enabled=true; PlayerCamera.enabled = false; CarCamera.enabled = true; } else { if (Input.GetKeyUp("r")){ // make character visible again player.gameObject.SetActiveRecursively(true); player.gameObject.active = true; // unparent player from everything player.transform.parent = null; // parent Exit Point to door Trigger exitPoint.parent = doorTriggerLeft.transform; // disable car as controllable GameObject.Find("car").GetComponent("DrivingScript").enabled=false; PlayerCamera.enabled = true; CarCamera.enabled = false;
