Question: Multiple scripts on one object

I know unity can use multiple scripts on one object and I'd like to take advantage of this.
I'm using the Invector Third Person Controller Lite and I'd like to make a script that temporally disables this controller when the player is hurt to apply knockback instead until they land.
Would making a separate script work this way? Just asking in case the Invector Third Person Controller is too complex for me to make adjustments to

 

Yes. find out what the script's type is, create public variable of that type so you can link it in editor, and then, when it's time to turn off the controller, simply use the enabled attribute for that script:

 

Should be perfect, so basically
When the player is damaged, disable controller and apply knockback to the rigidbody, then when the player is grounded, re-enable the controller
that should be work, just been making sure that it wouldn't mess anything up
