修改图像枚举

-1

所以我的朋友策划了这个枚举，我想缩短它。我想在字符串中缩短每个文件路径并将其折回String pokemonPath = "Pictures/Menu/MainMenu/";，然后像pokePath +" Cosmet.png一样，但我不确定如何实现它。此外，如果任何人有任何关于如何缩短它更多，我也很想听到它。除了它自己的类文件，所以将常量放在顶部将无法正常工作，它会给我一个错误。修改图像枚举

我并不真正使用枚举，所以我不知道如何有效地使用它们。

这是他的代码

这似乎只提供适量的文件路径的独立性...... – Thihara

@Thihara我不太确定你的意思？ – Exikle

我的意思是，这种粒度更适合于存储图像路径的目的。因为您可以将每个图像移动到您想要的任何路径。泛化只会限制你的选择......并迫使你对图像进行分类。另外如果你有一个图像分为两类？这是要么复制不正确的分类！ – Thihara

你如何将取决于它是什么你想达到的。

如果您想防止需要更换多个位置的路径，那么使用String常数是一个合理的想法。

喜欢的东西...

public interface PathConstants { 

    protected static final String SPRITES_PATH = "Pictures/Sprites"; 
    protected static final String SPRITES_MISC_PATH = SPRITES_PATH + "/Misc"; 
    protected static final String POKEMON_SPRITES_PATH = SPRITES_PATH + "/Pokemon"; 
    protected static final String POKEMONB_SPRITES_PATH = SPRITES_PATH + "/PokemonB"; 
    protected static final String STARTERS_MENU_PATH = "Pictures/Menu/Starters"; 
    protected static final String SPRITES_BATTLE_PATH = SPRITES_PATH + "/Battle"; 
    protected static final String MENU_BATTLE_PATH = SPRITES_BATTLE_PATH + "/BattleMenu"; 

}

那么你应该能够做到像...

public enum Images { 
    Cosmet(PathConstants.SPRITES_PATH + "/Cosmet.png"), CosmetB(
      PathConstants.POKEMONB_SPRITES_PATH + "/CosmetB.png"), CosmetStart(
      PathConstants.STARTERS_MENU_PATH + "/CosmetStart.png"), 

    Tykepol(PathConstants.POKEMON_SPRITES_PATH + "/Tykepol.png"), TykepolB(
      PathConstants.POKEMONB_SPRITES_PATH + "/TykepolB.png"), TykepolStart(
      PathConstants.STARTERS_MENU_PATH + "/TykepolStart.png"), 

    Embite(PathConstants.POKEMON_SPRITES_PATH + "/Embite.png"), EmbiteB(
      PathConstants.POKEMONB_SPRITES_PATH + "/EmbiteB.png"), EmbiteStart(
      PathConstants.STARTERS_MENU_PATH + "/EmbiteStart.png"), 

    // Balls 
    Pokeball(PathConstants.SPRITES_MISC_PATH + "/Pokeball.png"), Pokeball4(
      PathConstants.SPRITES_MISC_PATH + "/Pokeball4.gif"), 

    // Outlines 
    Outline1(PathConstants.MENU_BATTLE_PATH + "/Outline1.png"), Outline2(
      PathConstants.MENU_BATTLE_PATH + "/Outline2.png"), Outline3(
      PathConstants.MENU_BATTLE_PATH + "/Outline3.png"), Outline4(
      PathConstants.MENU_BATTLE_PATH + "/Outline4.png");

例如。

这意味着如果SPRITES_PATH发生变化，您只需将其更改为一个地方并重新编译。

不幸的是我不能把它放在一开始，因为它说“无法在定义之前引用一个字段” – Exikle

哦，我看到了，将常量放到另一个类中，然后... – MadProgrammer
