Description
PS7 Rewrite PS4-2 solution using a C++ class (ps7.cpp) [100 points]
(1) Download ProblemSet4-2 solution from the course Canvas
(2) Rename ps4-2-solution.cpp to ps7.cpp
(3) Add four classes, Artillery, CannonBall, Obstacle, and Target
(4) Then, re-write the rest of the code accordingly.
For the full credit,
a. Artillery class has member variables that fully describe the state of the artillery
b. CannonBall class has member variables that fully describe the state of the cannon ball
c. Obstacle class has member variables that fully describe the state of the obstacle
d. Target class has member variables that fully describe the state of the target
e. CheckHitTarget function needs to be replaced with
Target::CheckHitByCannonBall(double bx,double by) where mx and my are the
cannon-ball coordinate. (Let’s make Target and Obstacle classes be responsible for
collision check this time)
f. Add Obstacle::CheckHitByCannonBall(double bx,double by) where mx and my are the
cannon-ball coordinate, and use it in the main function.
g. DrawArtillery function needs to be replaced with Artillery::Draw
h. DrawCannonBall function needs to be replaced with CannonBall::Draw
i. MoveCannon function needs to be replaced with CannonBall::Move
j. FireCannon function needs to be replaced with CannonBall::Fire
k. GenerateObstacle needs to be replaced with Obstacle::Generate (* In ps4-2-
solution.cpp, GenerateObstacle function generates all obstacles. Obstacle::Generate
needs to be for one obstacle, and main function should run a for-loop to generate all
the obstacles.)
l. DrawObstacle needs to be replaced with Obstacle::Draw (* In ps4-2-solution.cpp,
DrawObstacle function draws all obstacles. Obstacle::Draw needs to draw only one
obstacle, and the main function should run a for-loop to draw all the obstacles.)
m. DrawTarget needs to be replaced with Target::Draw
n. MoveTarget needs to be replaced with Target::Move
o. Add a member function Target::Initialize, and let the main function call this function
for initializing the object instead of main function directly setting the coordinate and
size of the target. (Initialize member functions of other classes are optional for this
assignment).
Extra 3 points: Allow the user shoot up to five cannon balls simultaneously. Trajectories must be
drawn for all balls in the air.
Extra 3 points (Requires previous 3 extra points): Add a class called Explosion and modify the program
so that the explosion visual effect is visible when the ball hits an obstacle, not just the target.
Multiple explosions can be rendered simultaneously for this point. You don’t get this points if it the
motion of the target and/or the artillery stop while the explosion is visible.
Good luck!
Make sure your program can be compiled with no error in one of the compiler servers. Don’t wait
until the last minute. Compiler servers may get very busy minutes before the submission deadline!
