Making Minesweeper Window Resizable
Is it possible to create a resizable window for the game?
Yes, it's definitely possible to create a resizable window for your Minesweeper game. This can enhance the player's experience by allowing them to adjust the game window to their preference. Here's how you can implement this feature:
Step 1: Modify Window Creation
First, we need to modify how we create our window. In your Window class constructor, add the SDL_WINDOW_RESIZABLE flag:
// Engine/Window.h
class Window {
public:
Window() {
SDLWindow = SDL_CreateWindow(
Config::GAME_NAME.c_str(),
SDL_WINDOWPOS_UNDEFINED,
SDL_WINDOWPOS_UNDEFINED,
Config::WINDOW_WIDTH,
Config::WINDOW_HEIGHT,
SDL_WINDOW_RESIZABLE
);
}
// ... (rest of the class)
};Step 2: Handle Window Resize Events
Now we need to handle the SDL_WINDOWEVENT_RESIZED event. Add this to your main event loop:
// main.cpp
while (!shouldQuit) {
while (SDL_PollEvent(&Event)) {
if (Event.type == SDL_QUIT) {
shouldQuit = true;
} else if (Event.type == SDL_WINDOWEVENT) {
if (Event.window.event ==
SDL_WINDOWEVENT_RESIZED) {
int NewWidth = Event.window.data1;
int NewHeight = Event.window.data2;
GameWindow.HandleResize(NewWidth,
NewHeight);
UI.HandleResize(NewWidth, NewHeight);
}
} else {
UI.HandleEvent(Event);
}
}
// ... (rest of the game loop)
}Step 3: Update Window Class
Add a method to handle resizing in your Window class:
// Engine/Window.h
class Window {
public:
// ... (existing code)
void HandleResize(int NewWidth,
int NewHeight) {
SDL_SetWindowSize(SDLWindow, NewWidth,
NewHeight);
SDL_FreeSurface(
SDL_GetWindowSurface(SDLWindow));
}
// ... (rest of the class)
};Step 4: Update UI to Handle Resizing
Now, we need to update our MinesweeperUI class to handle resizing. This involves recalculating the size and position of UI elements based on the new window size:
// Minesweeper/UI.h
class MinesweeperUI {
public:
// ... (existing code)
void HandleResize(int NewWidth,
int NewHeight) {
WindowWidth = NewWidth;
WindowHeight = NewHeight;
RecalculateLayout();
}
private:
void RecalculateLayout() {
// Recalculate sizes and positions of UI
// elements - for example:
int CellSize =
std::min(WindowWidth / GridWidth,
WindowHeight / GridHeight);
// Update grid position and size
GridX =
(WindowWidth - (CellSize * GridWidth)) /
2;
GridY =
(WindowHeight - (CellSize * GridHeight)) /
2;
// Update other UI elements...
}
int WindowWidth{Config::WINDOW_WIDTH};
int WindowHeight{Config::WINDOW_HEIGHT};
int GridWidth{10}; // Example value
int GridHeight{10}; // Example value
int GridX{0};
int GridY{0};
// ... (other members)
};Step 5: Update Rendering
Finally, update your rendering code to use the new positions and sizes:
void MinesweeperUI::Render(
SDL_Surface *Surface) {
// Render grid
for (int y = 0; y < GridHeight; ++y) {
for (int x = 0; x < GridWidth; ++x) {
int CellSize =
std::min(WindowWidth / GridWidth,
WindowHeight / GridHeight);
int CellX = GridX + (x * CellSize);
int CellY = GridY + (y * CellSize);
// Render cell at (CellX, CellY) with size
// CellSize// ... (cell rendering code)
}
}
// Render other UI elements...
}By implementing these changes, your Minesweeper game will now have a resizable window. The game grid and UI elements will adjust their size and position based on the new window dimensions, providing a flexible and user-friendly interface.
Remember to test thoroughly to ensure all UI elements behave correctly when resizing, especially at extreme aspect ratios. You might want to implement minimum and maximum size limits to prevent the window from becoming too small or too large.
