Unity string formatting

Padding numerical values in strings

// add the desired number of "0"s for padding in front of the "."
// add the desired number of "0"s for precision after the "." (including rounding up/down)

string text = String.Format("Heading: {0:000.000}", heading);

// 12.3456789 = Heading: 012.346
// -1.2345678 = Heading: -001.234  

// extend formatting to include cases for positive, negative and zero values.

string text = String.Format("Heading: {0:+00.0;-00.0;±00.0}", heading)

// 12.3456789 = Heading: +12.3
//  0.0000000 = Heading: ±00.0     
// -1.2345678 = Heading: -01.2    

Format date and time nicely

// This formats the current date/time, but you can pass a custom DateTime object, if you like.

public static string DateTimeFormat()
{
    DateTime now = DateTime.Now;
    
    return now.ToString("yyyy-MM-dd HH:mm:ss.fff");
}    

// 2024-09-30 22:58:04.338

Add some formatting to your console output

// See at which time a method was called, if you reference the previous DateTimeFormat() method.   
// Quickly filter your console output by method name.
// See output from different components by colors.

public class Format {
    public static string Debug(string methodName, string logContent, Color classColor)
    {
        string hexColor = ColorUtility.ToHtmlStringRGB(classColor);
        return $"[{DateTimeFormat()}:<color=#{hexColor}>{methodName}]</color> {logContent}";
    }
}
    
// Call in your Debug.Log(Format.Debug("", "", Color.cyan));
