The WithAlpha method allows you to create a new Color instance with a modified alpha (transparency) value, while keeping the red, green, and blue components unchanged. This method is useful when you need to adjust the transparency of a color without altering its hue or brightness.
To use the WithAlpha method, call it on an existing Color instance and pass the desired alpha value as a float parameter. The alpha value should be between 0 (fully transparent) and 1 (fully opaque).
// Example of using the WithAlpha method Color originalColor = Color.Red; // A fully opaque red color Color semiTransparentRed = originalColor.WithAlpha(0.5f); // Creates a red color with 50% transparency // Output the RGBA values float r = semiTransparentRed.r; // Red component float g = semiTransparentRed.g; // Green component float b = semiTransparentRed.b; // Blue component float a = semiTransparentRed.a; // Alpha component (0.5)
