java - 如何最好地在 Java 中存储游戏配置变量

Question

我正在编写一个小型 Java 游戏，并将全局游戏设置存储在如下所示的类结构中:

public class Globals {
    public static int tileSize = 16;
    public static String screenshotDir = "..\\somepath\\..";
    public static String screenshotNameFormat = "gameNamexxx.png";
    public static int maxParticles = 300;
    public static float gravity = 980f;
    // etc
}

虽然使用起来非常方便，但我想知道这是否是可接受的模式。

Answer 1

将其存储在 .properties 文件中。

config.properties

tile.size=16
screenshot.dir=..\\somepath\\..

正在阅读

// Make sure this happens only the first time you start your application
Properties properties = new Properties();
// You can use FileInputStream, ClassLoader.getResourceAsStream or a reader too
properties.load(...)

使用它

int tileSize = Integer.valueOf(properties.getProperty("tile.size"));
String screenshotDir = properties.getProperty("screenshot.dir");

为了简化事情并尽量减少更改，您还可以这样做:

public class Globals {
    private static final Properties properties = new Properties();

    static {
        // do the loading here
    }

    public static final int TILE_SIZE = 
        Integer.valueOf(properties.getProperty("tile.size"));
    public static final String SCREENSHOT_DIR = 
        properties.getProperty("screenshot.dir");
    // etc
}
