This article mainly introduces "how to achieve the game of Tetris on C++". In the daily operation, I believe many people have doubts about how to realize the game of Tetris on C++. The editor consulted all kinds of materials and sorted out simple and easy-to-use methods of operation. I hope it will be helpful to answer the doubts of "how to realize the game of Tetris by C++". Next, please follow the editor to study!

Tetris C++

1. Create a project

two。 A total of two files need to be created, one main.cpp and one elsfk2.h. The compiler I use is vs2019.

3. Create a folder image under the source folder of the project

4. Rename the following two pictures to put them in the folder you just created

Elsfk.jpg

Elsfk_block.jpg

5. Copy the following code to the corresponding file

-the following is the contents of the main.cpp file # include "elsfk2.h" int main () {srand ((int) time (0)) / / create the game window RenderWindow window (VideoMode (COL*18/*+100*/, ROW*18-36), "ELSFK"); / / add the game background Texture T1 image/elsfk_block.jpg T2; t1.loadFromFile ("image/elsfk.jpg"); t2.loadFromFile ("image/elsfk_block.jpg"); Sprite sprite_Bg (T1); Sprite sprite_block (T2); NewBlock () Clock begin; float time1 = 0, time2 = 0; while (window.isOpen ()) {time2 = begin.getElapsedTime () .asSeconds (); begin.restart (); time1 + = time2; / / waiting for the user to press keyEvent (& window) If (time1 > delay) {time1 = 0; blockDrop ();} delay = SPEED_NOM; window.draw (sprite_Bg); drawBlock (& sprite_block, & window) Window.display () }}-the following is the elsfk2.cpp#pragma once#include / / image Processing header file / / # include # includeusing namespace sf # define ROW 22 / / Row # define COL 10 / column # define SPEED_NOM 0.5 / / interval between unaccelerated movements # define SPEED_QIK 0.05 / / the interval between accelerating motion int map [ROW] [COL] = {0} / / Game area size int blocktype; / / Square type int Delete=0; / / number of rows deleted float delay = SPEED_NOM; / / interval void Move_x (int) Void Rotate (); void ClearBlock (); void NewBlock (); void blockDrop (); void keyEvent (RenderWindow*); void drawBlock (Sprite*, RenderWindow*); bool check (); / / A two-dimensional array of 7 squares int a [7] [4] = {1, 3, 5, 7, 2, 4, 4, 5, 3, 4, 5, 3, 5, 4, 4, 5, 5, 5, 4, 5, 5, 5, 5, 5, 5, 5, 5, 5, 5, 5, 5, 7, 2, 3, 5, 5, 5, 7, 2, 3, 4, 4, 5, 2, 5, 5, 4, 5, 2, 5, 5, 5, 5, 5, 5, 5, 5, 5, 5, 5, 5, 5, 5, 7, 2, 5, 5, 5, 7,} / / the structure of the point struct point {int x, y;}; / / the current square point block [4]; / / the backup point bakblock of the square [4]; / / the processing key void keyEvent (RenderWindow * w) {Event e; bool rotate = 0; int x = 0 While (w-> pollEvent (e)) {if (e.type = = Event::Closed) {w-> close () } if (e.type = = Event::KeyPressed) {switch (e.key.code) {case Keyboard::Up: rotate = 1; break Case Keyboard::Left: X =-1; break; case Keyboard::Right: X = 1; break Default: break;}} if (Keyboard::isKeyPressed (Keyboard::Down)) {delay = SPEED_QIK } if (x) {Move_x (x);} if (rotate) {Rotate ();} / / eliminate the completed line void ClearBlock () {int k = ROW-1 For (int I = ROW-1; I > 0; I Murray -) {int count = 0; for (int j = 0; j)
