Unity 打印log时，使用StringBuilder比String好，String会产生垃圾，使用StringBuilder能避免String产生垃圾

using System;

using System.Diagnostics;

using System.Reflection;

using System.Text;

using UnityEngine;

public class Log

{

// private static StringBuilder _builder = new StringBuilder(1024);

public static void I(string tag, string format, params object[] args)

{

UnityEngine.Debug.Log(buildString(tag, format, args));

}

public static void W(string tag, string format, params object[] args)
{
    UnityEngine.Debug.LogWarning(buildString(tag, format, args));
}

public static void E(string tag, string format, params object[] args)
{
    UnityEngine.Debug.LogError(buildString(tag, format, args));
}

private static StringBuilder buildString(string tag, string format, params object[] args)
{
    StringBuilder _builder = new StringBuilder(1024);
    _builder.Clear();
    _builder.Append("Snake_");
    _builder.Append(tag);
    _builder.Append(": ");
    if (args != null && args.Length > 0)
    {
        _builder.AppendFormat(format, args);
    }
    else
    {
        _builder.Append(format);
    }

    return _builder;
}
