Switch between 1st person and 3rd person view

Hi i am using the wow camera script (great for 3rd person) I want to be able to switch to 1st person.Do I add script that disables wow script and position camera in player?

the best approach is to have 2 scripts. one for FPS and one for third person. then you can enable one of them and disable the other to change the camera. you can use 2 cameras and disable/enable them too but you don't need it. just initialize the camera position and other parameters in start function of your scripts.
