This is the last question about this game. |

If they overlap, then the distance between is less than zero. Calculate the distance between. Accounting for radius of pacman and width/height of ghosts. Also, for your map: 1. Choose mapa1 or mapa2 and remove the other from your code. |

I have the two maps to know how to do it in both ways, what I'm doing is just a prototype to learn. From what you've told me I haven't understood much, could you show me a bit of code to guide me. |

Last night, I was looking at the code for a Pacman game I made. Not quite useful for you. I used a simple 8-bit bitmap for the master map. Another bitmap for the main map. A third bitmap with color-based directions to tell the ghosts' eyes which way to go when they died. The third bitmap was so I didn't have to program path finding to find their starting locations. 1const int map_width = 44;
2const int map_height = 17;
3
4const char master_map[map_width * map_height + 1] =
5 "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx"
6 "x..........................................x"
7 "x..........................................x"
8 "x.. ..x"
9 "x.. xxxxxxxxxxxxx * xxxxxxxxxxxxx ..x"
10 "x.. ..x"
11 "x..........................................x"
12 "x.. ..x"
13 "x.. xxxxxxxxxxxxx xxxxxxxxxxxxx ..x"
14 "x.. ..x"
15 "x..........................................x"
16 "x.. ..x"
17 "x.. xxxxxxxxxxxxx s xxxxxxxxxxxxx ..x"
18 "x.. * ..x"
19 "x..........................................x"
20 "x..........................................x"
21 "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx";
22
23char game_map[map_width * map_height + 1];
24
25// During your game, you will be removing dots.
26// This will reset the map when new game is started.
27void reset_game_map()
28{
29 int i = 0;
30 for (while i < (map_width * map_height))
31 {
32 game_map[i] = master_map[i];
33 ++i;
34 }
35}
In my program, Pacman and the ghosts were the same size as a map cell. To tell if they collided was to tell the distance in the x and y directions The minimal x distance for them to not touch is 1/2 the width of pacman added to 1/2 the width of the ghost. Same goes for the y, but using height. Measure the distance between them. If the distances are less than the minimal distances in both directions then you have a collision

Thank you very much for all the help, I'm going to leave this game here and start another one. Now I want to make a version of space invader but simplified and with some changes. I'm going to start with the first lines of code and when I have the basics I'll create another thread for this game and start with new questions. |
