// There must be a button set up in the Input Manager called "Run"

I have the parent FPSCharacter, and in it I have 2 cameras. One (the main camera) for all, except weapons and one just for Weapons in order to hide the clipping with walls.
In the main camera I have my WeaponHolder. And the script for the camera is on the main camera and the camera for weapons.
Is it good or not?
