minecraft - Minecraft 如何处理特定的方块？

Question

所以 Minecraft 使用程序网格，它们如何处理特定的块？他们如何将石块和泥块分开？

我的世界只是一个例子。我现在想知道它在技术上是如何工作的。

如果您谈论的是块模型，例如纹理是如何分层的，Minecraft 使用.json文件作为最新 Minecraft 版本 1.8 的模型。该文件的示例.json如下：

{
    "ambientocclusion": false,
    "textures": {
        "particle": "blocks/glass",
        "glass": "blocks/glass",
        "obsidian": "blocks/obsidian",
        "beacon": "blocks/beacon"
    },
    "elements": [
        {   "__comment": "Glass shell",
            "from": [ 0, 0, 0 ],
            "to": [ 16, 16, 16 ],
            "faces": {
                "down":  { "uv": [ 0, 0, 16, 16 ], "texture": "#glass" },
                "up":    { "uv": [ 0, 0, 16, 16 ], "texture": "#glass" },
                "north": { "uv": [ 0, 0, 16, 16 ], "texture": "#glass" },
                "south": { "uv": [ 0, 0, 16, 16 ], "texture": "#glass" },
                "west":  { "uv": [ 0, 0, 16, 16 ], "texture": "#glass" },
                "east":  { "uv": [ 0, 0, 16, 16 ], "texture": "#glass" }
            }
        },
        {   "__comment": "Obsidian base",
            "from": [ 2, 0.1, 2 ],
            "to": [ 14, 3, 14 ],
            "faces": {
                "down":  { "uv": [ 2,  2, 14, 14 ], "texture": "#obsidian" },
                "up":    { "uv": [ 2,  2, 14, 14 ], "texture": "#obsidian" },
                "north": { "uv": [ 2, 13, 14, 16 ], "texture": "#obsidian" },
                "south": { "uv": [ 2, 13, 14, 16 ], "texture": "#obsidian" },
                "west":  { "uv": [ 2, 13, 14, 16 ], "texture": "#obsidian" },
                "east":  { "uv": [ 2, 13, 14, 16 ], "texture": "#obsidian" }
            }
        },
        {   "__comment": "Inner beacon texture",
            "from": [ 3, 3, 3 ],
            "to": [ 13, 14, 13 ],
            "faces": {
                "down":  { "uv": [ 3, 3, 13, 13 ], "texture": "#beacon" },
                "up":    { "uv": [ 3, 3, 13, 13 ], "texture": "#beacon" },
                "north": { "uv": [ 3, 2, 13, 13 ], "texture": "#beacon" },
                "south": { "uv": [ 3, 2, 13, 13 ], "texture": "#beacon" },
                "west":  { "uv": [ 3, 2, 13, 13 ], "texture": "#beacon" },
                "east":  { "uv": [ 3, 2, 13, 13 ], "texture": "#beacon" }
            }
        }
    ]
}

所有块模型都是在这样的文件中制作的，玩家可以修改这些文件。然后游戏进入并读取它们，从.json数据中创建模型。有几个 3rd 方程序可以帮助制作这些文件。

如果您有兴趣了解文件是如何读取的，那么Minecraft Coder Pack.json是另一个用于反编译 Minecraft 的好程序，它是另一个 3rd 方程序。

好吧，如果你想看看 Minecraft 如何区分石块和泥块，例如，他们会这样做：

1. 实际的块本身存储在一个名为 Blocks ( https://pastebin.com/ykjkBmxv )的大类中，然后注册，然后如果 Minecraft 想要检查您正在查看的块，它可以从玩家走向方块，然后Minecraft检查加载的块数据，以找到该位置的方块。
2. Minecraft 也有.json用于配置方块外观的文件，如下所示：

{
    "parent": "block/cube_all",
    "textures": {
        "all": "blocks/dirt"
    }
}

Minecraft 还有blockstate .json一些文件，用于定义方块的变体，例如树苗的生长状态。
