MILESTONE $1$: THIRD CLASS $(40\%+)$

a$.$ Set up the scene exactly as described in the previous section.

b$.$ Implement keyboard control for the sphere using WASD keys:

i$.\text{'}W\text{'}$ moves the sphere forward

ii$.\text{'}$S$\text{'}$ moves the sphere backwards

iii. $\text{'}$D$\text{'}$ rotates the sphere clockwise

iv$.\text{'}$A$\text{'}$ rotates the sphere anti$-$clockwise

v$.$ The game should enter GameOver state if the player moves into the water, and

then stop.

c$.$ Use kSphereSpeed and kRotationSpeed as constants for storing the speed

at which you move androtate the sphere. Choose a reasonable value that

works well in the lab and on your machine.

d$.$ Implement movement for your top$-$down camera by adding keyboard keys:

i$.\text{'}$Up$\text{'}$ moves the camera forward along the world z$-$axis

ii$.$ 'Down' moves the camera backwards along the world z$-$axis

iii. 'Right' moves the camera right along the world $x-$axis

iv$.$ 'Left' moves the camera left along the world $x-$axis

e$.$ The P key causes the game to enter a Paused state. In the Paused state:

i$.$ Nothing should move

ii$.$ Hitting the $P$ key causes the game to transition to the Playing state

f$.$ In all game states, the player should be able to press the Escape key to quit the game.

g$.$ The sphere should pick up cubes that are very close to it:

i$.$ Calculate the distance between the sphere and all cubes.

ii$.$ If the distance is not greater than the sum of the sphere's radius and

half the width of the cube, the cube should be picked up by the

sphere.

iii. For example, if the sphere's radius is $10$ units, then any cube

within $(10+\frac{5}{2})12\mathrm{.}5$ units ofsphere should be picked up$.$

iv$.$ Picked up cubes should not be visible $($think of a way to make the cube

disappear$).$

h$.$ The code you submit MUST compile without errors.
