🛠️ 4. Installing raylib

To install raylib on your computer, you need to execute corresponding commands based on your operating system. The installation process is simple and direct; let’s take a look! ✨

1. Windows:

   • You can use vcpkg, a popular C++ package management tool. In your command prompt, enter the following command:

     vcpkg install raylib
     

   • This command tells vcpkg to download and install raylib so that you can reference it in your projects. After completing this step, don’t forget to add the vcpkg installation path to your system environment variables!

2. Linux:

   • If you are a Linux user, installing raylib is also straightforward. Simply use your package manager! For Ubuntu, execute the following command:

     sudo apt install libraylib-dev
     

   • Here, sudo means you’re executing the command as a superuser, and apt is Ubuntu’s default package manager that will download and install the raylib development package.

3. macOS:

   • On macOS, you can use Homebrew, a well-known package management tool. Open your terminal and run:

     brew install raylib
     

After completing these steps, you’ll be able to include and use raylib in your code projects! 🎉

🖥️ 5. Creating Your First Window

Now we can officially start creating our first window! The code below creates a simple window that displays some text to the user. Give it a try!

#include "raylib.h" // Include the raylib library

int main(void)
{
    // Set the width and height of the window
    InitWindow(800, 450, "raylib [core] example - basic window"); // Initialize the window, title "Basic Window"

    // Main loop until the user closes the window
    while (!WindowShouldClose()) // If the window hasn't been closed yet
    {
        BeginDrawing(); // Start drawing
        ClearBackground(RAYWHITE); // Clear background to white
        DrawText("Congrats! You created your first window!", 190, 200, 20, LIGHTGRAY); // Draw text
        EndDrawing(); // End drawing, display content
    }

    CloseWindow(); // Close the window and release resources
    return 0; // Exit the program normally
}

In this example, the InitWindow function is used to create a window that is 800 pixels wide and 450 pixels high, with the title “raylib [core] example - basic window.” The main loop will continue running until the user closes the window. Inside the loop, we use BeginDrawing and EndDrawing to indicate the start and end of the drawing area. Additionally, ClearBackground(RAYWHITE) clears the background for clarity, and DrawText draws the text within the window. Lastly, the CloseWindow() function closes the window and frees all resources, giving you a quick and easy introduction to window creation! 😄

🔷 6. 2D Graphics Drawing Example

raylib also supports simple 2D graphic rendering. The following example shows how to draw rectangles and text in your window:

#include "raylib.h" // Include the raylib library

int main(void)
{
    InitWindow(800, 450, "raylib [core] example"); // Create window

    // Main game loop until the user closes the window
    while (!WindowShouldClose()) // Ensure the window is not closed
    {
        BeginDrawing(); // Start drawing
        ClearBackground(RAYWHITE); // Clear background to white

        DrawRectangle(200, 200, 150, 100, BLUE); // Draw a blue rectangle
        DrawText("Press ESC to exit", 10, 10, 20, DARKGRAY); // Draw exit instruction to the window
        
        EndDrawing(); // End drawing
    }

    CloseWindow(); // Close the window
    return 0; // Exit normally
}

In this example, we again use InitWindow to create the window. In the main loop, we use BeginDrawing and EndDrawing, along with ClearBackground(RAYWHITE) to keep the window background clear. In this loop, we added a new line of code, DrawRectangle(200, 200, 150, 100, BLUE), which draws a blue rectangle positioned at (200, 200), with a width of 150 pixels and a height of 100 pixels. The DrawText function provides a prompt for users to exit by pressing ESC. Through these examples, we’ve gradually showcased the powerful features of raylib, and we hope to inspire more creative ideas in you! 🚀

🌟 7. Texture Drawing Example

Next, let’s explore how to load fonts and draw textures with text. This example allows users to change the color of the text by pressing keys – a truly magical feature!

#include "raylib.h" // Include the raylib library

int main(void) {
    const int screenWidth = 400; // Set window width to 400
    const int screenHeight = 300; // Set window height to 300
    SetTargetFPS(60); // Set target frame rate to 60
    InitWindow(screenWidth, screenHeight, "DrawTexture Example"); // Create window

    int fontsize = 20; // Set font size to 20
    char *getfont = "fonts/JuliaMono-Light.ttf"; // Path to font file
    Font font = LoadFontEx(getfont, fontsize, 0, 250); // Load custom font
    char *ptr = "Texture"; // Text to be drawn
    int x = 50, y = 30; // Initial drawing coordinates for text

    // Generate a solid white image
    Image image = GenImageColor(screenWidth, screenHeight, WHITE);
    
    // Draw text on the image
    ImageDrawTextEx(image, font, ptr, (Vector2){ x, y }, fontsize, 0, BLUE); // Draw text in blue
    Texture2D texture = LoadTextureFromImage(image); // Load texture from image

    while (!WindowShouldClose()) { // Main loop
        // Check for key events to change text color
        if (IsKeyDown(KEY_ENTER) || IsKeyDown(KEY_SPACE)) {
            Color color = IsKeyDown(KEY_ENTER) ? RED : PURPLE; // Determine color based on key
            ImageDrawRectangle(image, x, y, 300, 30, WHITE); // Erase old text area
            ImageDrawTextEx(image, font, ptr, (Vector2){ x, y }, fontsize, 0, color); // Draw new text
            
            UnloadTexture(texture); // Unload old texture to save memory
            texture = LoadTextureFromImage(image); // Reload texture from new image
        }

        // Start drawing
        BeginDrawing();
        ClearBackground(WHITE); // Set background to white
        DrawTexture(texture, 0, 0, WHITE); // Draw current texture
        EndDrawing(); // End drawing
    }

    // Release resources
    UnloadImage(image); // Unload image resources
    UnloadTexture(texture); // Unload texture resources
    CloseWindow(); // Close window
    return 0; // Exit normally
}

In this example, we first set the dimensions of the window, and use SetTargetFPS(60) to maintain a smooth frame rate. To load a custom font, we call LoadFontEx(getfont, fontsize, 0, 250) to load the specified font, and run a series of logic to draw a blue text. Pressing ENTER or SPACE will activate a different color for the text while showcasing raylib’s ability to efficiently handle images and textures! Here, we also used UnloadTexture to optimize memory usage and prevent memory leaks, which is a good programming practice! 🌟

With these examples and code explanations, you now have a foundational understanding of using raylib to develop simple window applications. It’s time to unleash your creativity and expand on these examples – let your imagination shine! 🎨
