Grid Game
I created this game as a Java GUI lab. Click on a grid location and the "distance" to the target is displayed. "Distance" is defined as "delta X plus delta Y". To the right, I clicked on the cell at row 2 and column 2. My second selection was 4 rows down and 4 columns right. My third selection was 3 columns right and 5 rows up. You will notice the "16" cell is 8 steps away from both "8" cells. The fourth selection was off by 2 steps. And the fifth selection hit the target.This is a remarkable vehicle for iteratively demonstrating programming ...
1. Draw the board and quit.
Do you need a data structure to represent
the board?
2. Move the "draw board" functionality to a function.
3. Add random number generation of the target location.
4. Add an infinite loop and prompt/accept row & col input. Simply put a "marker" at the specified location.
5. Add the "delta X plus delta Y" algorithm.
How should integer-to-string conversion
be implemented?
How should "right justification" be
implemented?
6. Replace arrays with vector objects.
7. Refactor the game "engine" as a class.
int main( void ) {
Grid_Game game;
int row, col;
while (1) {
cout << "row col ... ";
cin >> row >> col;
game.make_guess( row, col );
}
}
