1. swap(Block p1, Block p2): This function swaps the position of two blocks (p1 and p2) by swapping their row and column values.

2. doEvent(RenderWindow *window): This function handles user events, such as mouse clicks and window closures. It checks for mouse button presses and updates the positions of the clicked blocks accordingly.

3. check(): This function checks for matches in the game grid. It iterates through each block and checks if there are three identical blocks in a row or column. If a match is found, it increments the match counter for those blocks.

4. doMoving(): This function moves the blocks to their appropriate positions after a swap or match has occurred. It checks each block's position and adjusts it if it is not aligned with its row or column. It sets the isMoving flag to true if any blocks are still moving.

5. xiaochu(): This function handles the removal of matched blocks by decreasing their alpha value (transparency). It sets the isMoving flag to true if any blocks are still being removed.

6. huanYuan(): This function reverts the last swap if no match occurs as a result of the swap. It checks if a swap has occurred (isSwap flag) and if all blocks have finished moving (isMoving flag).

7. updateGrid(): This function updates the game grid by moving blocks down if there are empty spaces below them and generating new random blocks at the top. It iterates through each column from bottom to top and replaces matched blocks with new random blocks.

8. drawBlocks(Sprite *sprite, RenderWindow *window): This function draws the blocks on the game window using the provided sprite. It iterates through each block in the game grid, sets the sprite's texture rectangle and color based on the block's properties, and then draws the sprite on the window.

9. initGrid(): This function initializes the game grid by assigning random block types to each block and setting their initial positions.

10. main(): The main function of the program. It initializes the window, loads textures for the background and block sprites, calls initGrid() to initialize the game grid, and enters the main game loop. Inside the game loop, it calls the various functions in the correct order to handle events, update the game state, and render the game screen.

These functions together implement the logic and rendering of a basic match-three puzzle game using C++ and SFML.
