Steps:
The second big step is to create the main interface, separate the drawing interface from the initialization of interface elements, and make the logic clearer. The so-called interface refers to frame, background, title, interface size and other contents; Interface elements refer to, for example, adding item s to combox. In the main interface, the core problem is to handle mouse events, ensure that the current chess piece falls in the accurate position, and prompt the user to switch roles; There is to judge the victory of the game.
1.init initialization interface
Use QPainter to draw the interface background, add frame and interface element parts to the ui designer, and beautify the buttons through the style sheet; Add a checkerboard widget using gridLayout; Set the window title; Set the Gobang title; set and display black and white chess; the ui Designer's interface is as follows. Find the corresponding relationship when looking at the code.
2. Interface element initialization
This logic is not written well, and the actual program should not have this part. It is more appropriate to decompose initialization into two actions.
3. Click the start button
First, configure the button sound effect, empty (initialize) the chessboard, set the role, and connect the mouse signal (chessboard) As with the refresh interface function, the refresh interface function will save the coordinate information into a two-dimensional array, and use the two-dimensional array as a parameter to call the method of refreshing the chessboard provided by the chessboard class, so as to refresh the interface. At the same time, you should switch roles and add dubbing for the fall. Judge whether the player wins. Once a player wins, a dialog box pops up to congratulate the player.
4. Judge whether the player wins
Idea: the red and green lines represent the double-layer loop, the red line represents the memory loop, and the green line represents the outer loop. Therefore, when traversing, it will be traversed in the order from top to bottom and from left to right. Therefore, if each chess piece is regarded as the first chess piece of "five son Lianzhu", it only needs to detect the "five son Lianzhu" in four directions, as shown by the blue line in the figure. Once the "five son Lianzhu" is detected "Stop traversing immediately and return to the winning player.
5 window closed
When you click "exit the game" or "X", you will be prompted whether to exit. Click Yes to exit immediately, otherwise you will not exit.
effect
1. You can write your own algorithm on this basis to make a "man-machine combat mode";
2. On this basis, combined with network port programming, public network war can be realized.
