Switch between mouse controller character to controlling camera?

• want to let mouse input control player aim and be able to toggle on camera control via mouse.

• plan to have one block of script in which the mouse input is used to control player movement in 3rd person.

• second block of script will allow the mouse input to control the orbit of the camera rather than player movement.

-What type of code should I write to toggle between the two modes? Should it be something like:

if keypressed

{mouse controls the camera}

else

{mouse controls the player}

Or should it be:

var camerastate = 0

onkeydown camerastate = 1

onkeyup camerastate = 0

case camerastate 1: {mouse controls the camera}

camerastate 0: {mouse controls the player}

I feel like using if/else to check which block of script to be using to handle mouse input is not the right way to do it? But it doesn't seem using case/switch is the appropriate way to toggle between control modes.
