The "Rainbow Transition with SFML" code is a C++ program that utilizes the Simple and Fast Multimedia Library (SFML) to create an engaging visual effect.

🌈 Rainbow Transition with SFML(SFML LINKED) 🎮

This C++ code, using the Simple and Fast Multimedia Library (SFML), creates a mesmerizing 🌈 rainbow transition effect on a rectangle 🟩 that covers the entire window. The rectangle smoothly changes colors over time, creating a rainbow-like animation.

📦 Dependencies

Before running the code, make sure you have SFML correctly set up in your development environment.

💻 Code Description

This code provides an engaging example of utilizing SFML for graphical applications. It demonstrates how to create a visually stimulating rainbow transition effect using a combination of time-based color calculations, HSV to RGB conversion, and simple rendering techniques. The result is an interactive and aesthetically pleasing animation that smoothly transitions through a spectrum of colors, offering an enjoyable visual experience to users.

🌈 HSV to RGB Conversion

A custom function, HSVtoRGB, is defined to convert Hue-Saturation-Value (HSV) color values to Red-Green-Blue (RGB) color values. This function is used to generate the rainbow color transition.

🎯 Main Function

In the main function:

• We create an SFML window of size 800x600 pixels.
• We define an SFML Clock to measure time.
• An sf::RectangleShape named rectangle is created, initially covering the entire window.

🌟 Rainbow Transition

Inside the main loop:

• We calculate the current color based on elapsed time, resulting in a smooth color transition.
• The color transition speed can be adjusted by changing the factor used in fmod(time * 50, 360).
• The setFillColor method is used to set the fill color of the rectangle to the calculated color.

🎨 Rendering

We clear the window, draw the rectangle with the current color, and display it.

▶️ Running the Code

Compile this C++ code with SFML properly linked to your project. When you run the executable, a window will appear, displaying the rainbow transition effect on a rectangle covering the entire window.

Feel free to adjust the code parameters, such as the window size or color transition speed, to customize the effect according to your preferences.

Note: If you encounter any issues with missing DLLs or errors, ensure that you have the necessary SFML DLLs in the same directory as your executable or in a directory included in the system's PATH environment variable.

Happy coding! 🚀
