I need c$++$ code for this question. MILESTONE $2$: LOWER SECOND CLASS $(50\%+)$

a$.$ Setup an isometric camera that can be activated by pressing the $"2"$ key.

i$.$ The camera should be positioned at $(150,150,-150),$ rotated by $-45$ degrees about

its local $y-$axis

and then by $45$ degrees about its local $x-$axis $($the order is important, why?$).$

ii$.$ If the isometric camera is active, pressing the $"1"$ key should reactivate the top$-$down

camera.

b$.$ Reward the player with points whenever the sphere picks up a cube

i$.$ Create an integer variable named "playerPoints" for tracking points accumulated

ii$.$ When the sphere "picks" up a cube, add $10$ to the player's points.

iii. Display the players points at the top and aligned to the right of the game

window in the format"Points: $x^{\text{'}\text{'}}$ e$.$g$.$ after picking up all four cubes, "Points:

${40}^{\text{'}\text{'}}$ should be displayed

c$.$ When $4$ of the cubes are picked up$,$ the sphere should grow in size.

i$.$ Implement this by scaling the sphere to $1\mathrm{.}2$ its initial size, this will make the radius

of the sphere $12$units.

ii$.$ After scaling up$,$ the y position of the sphere must be changed so that part of it

does not appearbelow the floor $($hint: consider the sphere's new radius$).$
