Q$\mathrm{.}1.($i$)$ Write a C# Monobehaviour script to attach to a Unity$3$D game object which automatically destroys the object as soon as it is either behind the camera or more than a defined distance away from it$.$ This defined distance should be available as a value that can be edited in the inspector. $[8]($ii$)$ What are C# Coroutines? $[2]($iii$)$ Write a Coroutine which carries out a sequence of actions over time: $[8]$ Gradually $($frame by frame$)$ moves its local game object at a speed of $1$ metre per second towards a Vector$3$ position. $$ After the game object arrives at the position, waits $2$ seconds. $$ Then moves the game object in the same way to a second Vector$3$ position. Your Coroutine should use the following signature: IEnumerator MoveBetween$($Vector$3$ pos$1,$ Vector$3$ pos$2)\{\}($iv$)$ Write a general$-$purpose version of your Coroutine which: $[2]$ Moves the game object between each position in a List rather than just two positions. $$ After arriving at each position, waits for the time defined in the Float, before continuing to the next Vector$3$ in the List. Your Coroutine should use the following signature: IEnumerator MoveBetween$($List positions, float waitTime$)\{\}$
