Godot存档系统

可能是最简单的存档系统？ConfigFile功能的应用

//示例：和实际技术无关
public LineEdit playerName;
public ColorPickerButton playerColor;

public override void _Ready()
{
	playerName = this.GetTree().CurrentScene.GetNode<LineEdit>("Control/PlayerName/LineEdit");
	playerColor = this.GetTree().CurrentScene.GetNode<ColorPickerButton>("Control/PlayerColor/HBoxContainer/ColorPickerButton");
}

保存数据

ConfigFile相关函数：

public void SetValue(string section, string key, Variant value)
    					//保存分区，变量索引名，保存内容
public Error Save(string path)
    		//保存路径

在Godot中 ”user://pathname“ 的路径格式可将文件保存至游戏目录外（C盘区），相当安全哈

//示例
public void Save()
{
	ConfigFile config = new ConfigFile();
	config.SetValue("Settings", "name", playerName.Text);
    config.SetValue("Settings", "color", playerColor.Color);
	config.Save("user://settings.cfg");
}

public Error Load(string path)

//示例
public void Load()
{
    ConfigFile config = new ConfigFile();
	Error result = config.Load("user://settings.cfg");
	if(result == Error.Ok)
	{
		playerName.Text = (string) config.GetValue("Settings", "name");
		playerColor.Color = (Color)config.GetValue("Settings", "color");
    }
}

存档加密

将Save()替换成SaveEncryptedPass()，将Load()替换成LoadEncryptedPass()，后接string变量作为密钥。

//示例
private string key = "guoyuxiniubi";

config.SaveEncryptedPass("user://settings.cfg", key);
Error result = config.LoadEncryptedPass("user://settings.cfg", key);

优雅地保存任何数据！基于Resource类的存档系统
