Collaboration Policy

Collaboration is strongly ENCOURAGED. You will be working in teams, but programs must represent YOUR OWN original work. Teams should work on the algorithm together and help debug/test each others code. However, copying code from ANY source (any book, current or past students, past solutions, the web, etc.) is STRICTLY FORBIDDEN. Code between teamates will be similar, but you are not allowed to just copy a teamate's solution.

Code that is turned in, must be contained in a .cpp file named main.cpp. Files of any other format will not be graded (e.g. main.doc, main.txt, etc…).

You must turn your work in from a lab computer on campus.

Turn in online to as7-(group letter) folder. If you turn your assignment in to the wrong folder, your assignment may not be graded. If it is graded, you will lose 2 pts (out of 10).

Remember to include the following header information at the top of your program;

// Course: CS 10
//
// Lecture Section: ... 001 or 002
// Lab Section: ... 021, 022, etc)

Problem Definition:

For this assignment you will impliment the final moon lander game! You will have to add some code to ccc_win_main, create a collision detection function, add a function that draws a simple landscape, and add a function that draws an explosion based on the position of the ship.
You have already written some functions that draw a landscape and draw an explosion. As in the previous assignments, the draw landscape function is passed nothing, and returns void, the draw explosion function is passed a point that represents the position of your ship, and returns void. Keep your landscape simple, have no more than THREE places to land as in the example main below! This means there should be no more than 5 lines drawn in your landscape, and they should only be horizontal, and vertical.
For the collision detection function, you will pass it a SINGLE Point object that represents the position of the ship. The point that represents your ship should be at the bottom-center of your ship. The function will then check to see if that point is inside your landscape, if it is, the function will return true, otherwise it will return false. The easiest way to do this is to break up your landscape into squares (as mentioned only draw your landscape as a sequance of horizontal lines, followed by vertical lines), the area under each horizontal line would constitute a square. Then, all you need to do is check if your point lies within any of the squares. For example; if the upper left corner of the square was at point (0,3500), and the lower right point of the square was at point (2000,0), to check if the point representing your ship was inside the box you would use the statement:
if(x >= 0 && x <= 2000 && y <= 3500)
{
//inside the square
}
else
{
//outside the square
}
This would need to be done for each square, so you will need to use a switch statement or an if-else if structure. Becuase this is a relatively simple way to check for collisions, it is OK if your ship *lands* on a wall (vertical line). Also, since the point representing your ship will be in the at the ship's center, it is OK if half your ship passes through a vertical line/wall before the collision is detected.
You will then need to modify your ccc_win_main function. The program should continue until the ship either lands, or explodes. At the point in ccc_win_main where you were previously drawing the ship, you will now need to call your collision detection function to decide weither you will draw the ship, or draw an explosion. If there is no collision you can just draw the ship, otherwise you need to check the ship's current velocity. If the ship is over some acceptable negative velocity, it has landed safely, otherwise KABOOM! Using the code that was given for assignment 6, I found that any velocity greater than or equal to -17.5 was acceptable but difficult to land. For an easier game (and testing my code), a velocity greater than or equal to -35 was reasonable.
After the ship lands safely or explodes, you will use a break statement (page 137) to exit the main animation loop, this should cause the program to end.
The ship should move as specified in assignment 6, using the set postion, velocity, and acceleration functions you wrote. The controls for the thrusters should be exactly as in as6.

Rubric: (10 pts total)

1.5 pt:  Collision function detects collision with landscape and returns true
0.5 pt:  Collision function returns false when there is no collision
0.5 pt:  Landscape has no more than three landing pads
0.5 pt:  Point that represents ship is located at the bottom center of ship drawing (don't draw this point though)
0.5 pt:  Correctly breaks out of animation loop when ship lands or explodes 
1    pt:  On landing, draws ship when velocity is greater than or equal to -17.5
1    pt:  Draws explosion when ship lands too fast
1    pt:  Just draws ship when no collision is detected
