# Day 44/100 100 Days of Code

I focused on working on the main menu today and some window settings.

### Full-Screen Window

The application now starts on full screen. I did it, by adding SDL\_WINDOW\_FULLSCREEN as the last argument of the SDL\_CreateWindow() function.

```cpp
window = SDL_CreateWindow("Rebuild Back Better",
						  SCREEN_WIDTH,
						  SCREEN_HEIGHT,
						  SDL_WINDOW_FULLSCREEN);
```

### Getting the width and height of the window

Getting the size of the window is quite easy. The function SDL\_GetWindowSize() can be used to get the values. The variables that hold the values of the window's size are passed as arguments with their memory address location to assign a value to them directly.

```cpp
SDL_GetWindowSize(window, &windowWidth, &windowHeight);
```

### Loading Fonts Function

I used a similar technique to the SDL\_GetWindowsize to apply a value to a bool variable. The variable is used to check if loading the font is successful. The application exits if it fails. The second argument is a string with the URL to the TTF font file and the last argument is the font's size.

```cpp
TTF_Font *Game::LoadFont(bool *hasFontLoaded, std::string urlToFont, unsigned int fontSize)
{
	TTF_Font *font = TTF_OpenFont(urlToFont.c_str(), fontSize);
	if (font == nullptr)
	{
		std::cout << "Failed to create font ";
		std::cout << SDL_GetError() << std::endl;
		*hasFontLoaded = false;
		return nullptr;
	}
	*hasFontLoaded = true;
	return font;
}
```

### Main Menu Selection

The color of the menu options should be changed based on the current selection and if the continue option is available. I created an enumerator to handle the states and an integer variable to hold its value.

```cpp
enum MenuOptionSelection
{
	ContinueSelected = 0,
	StartSelected,
	ExitSelected
};

static int currentMainMenuSelection;
```

***It is important to remember that I will need to use the cursor for the menu selection.***

### Game State Switch

On the Main\_Menu, I load the menu's fonts first and then, run the MainMenu() method to build the menu.

```cpp
if (!hasLoadedTitleFont)
{
		titleFont = LoadFont(&hasLoadedTitleFont, 
							 "/Users/chrisd/Desktop/Rebuild Back Better/fonts/ArianaVioleta-dz2K.ttf",
							 100);	
					
		if (!hasLoadedTitleFont)
		{
			std::cout << "Title font has not loaded" << std::endl;
			exit(-1);
		}
}
				
if (!hasLoadedMenuFont)
{
	menuFont = LoadFont(&hasLoadedMenuFont,
					    "/Users/chrisd/Desktop/Rebuild Back Better/fonts/CfArpineDemoRegular-q2Zr2.ttf",
						60);
										
    if (!hasLoadedMenuFont)
    {
        std::cout << "Menu font has not loaded" << std::endl;
	    exit(-1);
    }
}
				
LoadMainMenu();
```

### MainMenu() Method

I changed the game's title color, added the color values that are going to be used for the options, and created a switch to set the color of each option accordingly. It will be also used to handle selections.

```cpp
void Game::LoadMainMenu()
{
	SDL_Color titleTextcolor = {0xE0, 0xAA, 0x95};
	
	// Title
	titleTextSurface = TTF_RenderText_Solid(titleFont,
											"Rebuild Back Better",
											titleTextcolor);
	
	if (titleTextSurface == nullptr)
	{
		std::cout << "Failed to create title texture surface ";
		std::cout << SDL_GetError() << std::endl;
		exit(-1);
	}
	
	titleTextTexture = SDL_CreateTextureFromSurface(renderer, titleTextSurface);
	
	const SDL_FRect titleHolder = {static_cast<int>((float)SCREEN_WIDTH * 0.27),
							static_cast<int>((float)SCREEN_HEIGHT * 0.05),
							static_cast<float>(titleTextSurface->w),
							static_cast<float>(titleTextSurface->h)};
							
	SDL_RenderTexture(renderer, titleTextTexture, nullptr,
					  &titleHolder);
	
	SDL_DestroySurface(titleTextSurface);
	titleTextTexture = nullptr;
	
	// Menu Options
	SDL_Color notSelected = {0xff, 0xff, 0xff};
	SDL_Color disabledOption = {0x10, 0x10, 0x10};
	SDL_Color selectedOption = {0xE0, 0xAA, 0x95};
	
	switch (currentMainMenuSelection)
	{
		case ContinueSelected:
			break;
			
		case StartSelected:
			break;
			
		case ExitSelected:
			break;
	}
}
```

Tomorrow I will use the window width and height values to place the title and finish the menu options.
