*附录：如何制作玻璃板
玻璃板是一种标准的不完整透明方块。它拥有复杂的连接状态和复杂的碰撞箱设定，在使用不同连接状态时的模型和碰撞箱都各不相同，这就大幅增加了还原玻璃板的难度。本文基于minecraft:connection方块特征来制作玻璃板。
制作相关模型
我们注意到，minecraft:geometry组件可以根据条件选择性显示骨骼，因此可以在一个模型中直接指定玻璃板的所有状态。
创建一个模型，起名叫geometry.glass_pane。注意使用逐面 UV。
指定一个center骨骼，代表中心处的玻璃板模型，显然这个模型无论在任何情况下都应该存在。再指定一个north骨骼，代表和北方连接时显示north骨骼，读者会在创建时在面板上看到一个^N的符号，那就是北方，请将north创立在中心骨骼的北侧。其他骨骼同理，但目前我们暂时不急于建立其他方向的骨骼，之后我们会解释为什么。
建立中间模型和北侧玻璃板模型
然后，我们从原版的文件中找到玻璃的贴图（
glass.png）和玻璃板顶部（glass_pane_top.png）的贴图，导入到 Blockbench 中，方便我们后续调试。
导入玻璃板贴图
导入好之后，先隐藏north骨骼可见性，调center骨骼。这里我们来看左侧的「面属性」，点击顶和底的贴图，将其改为 glass_pane_top.png，这样顶和底就会在预览时使用玻璃板顶部的贴图。并且，在顶和底使用top的材质实例，方便我们后续使用minecraft:material_instances组件。
通过面属性微调每个模型使用何处的 UV
对顶底使用不同的贴图和材质实例
这里我们逐面细调，将东南西北的 UV 拉到玻璃贴图正中间的位置，然后将顶底的 UV 拉到玻璃板顶部贴图中间的位置，这是为了还原原版的效果。
调整东西南北的 UV
调整顶底的 UV
然后我们启用north骨骼，打开「面属性」，这里我们可以直接禁用南北方向的面，因为靠北一侧的面贴图不可见是原版设定，而靠南一侧因为在方块内部所以设定为不可见。同样，顶和底的贴图改为 glass_pane_top.png，并且在顶底使用top的材质实例。细调东西顶底的贴图如下图所示。
调整东西的 UV，西在最左，东在最右
调整顶底的 UV，若需要极致地还原原版，请将顶的 UV 旋转 180°
然后，复制north骨骼，粘贴为south、west、east骨骼。现在粘贴是为了应用对north骨骼细调的每个面的更改。然后调整每个骨骼的位置和旋转值，注意west放在西侧，east放在东侧，south放在南侧。然后，调整三个骨骼的 y 轴旋转值分别为90、-90、-180。
玻璃板模型
到这里事情还没有结束。在有连接状态下，我们如此定义会导致玻璃板中间出现多余的像素，因此必须进行剔除。我们把center复制 4 次，分别叫center_east、center_west、center_south、center_north，代表东西南北面的中间部分贴图。在北侧有连接时，我们就把center_north骨骼禁用，以此类推。然后，我们把center的东西南北面全部禁用，改名叫center_top_bottom，代表中间部分的顶底贴图。
玻璃板模型（完整版）
这还并不是全部！注意到物品栏内的玻璃板是有边缘的，因此我们还必须增加edge_east、edge_west、edge_south、edge_north骨骼，只需要全部复制north、south、west、east骨骼并粘贴，然后在「面属性」中启用北面贴图并使用top的材质实例即可。
如果你已经快被逼疯了，下面有现成的模型代码供你取用。但如果你想成为一名建模师，就必须意识到这些工作已经算是很简单了。
该模型的 json 代码
有需要的读者也可直接取用，但我们还是建议读者自行尝试一次建模，尤其是初学者！

规定方块行为
现在我们来正式编写玻璃板的行为。首先定义玻璃板，注意这里需要使用1.26.0以上的格式版本。我们在根components下规定未连接时的玻璃板：
glass_pane.block.json
{
"format_version": "1.26.20",
"minecraft:block": {
"description": {
"identifier": "test:blast_proof_glass_pane",
"menu_category": {
"category": "construction"
}
},
"components": {
"minecraft:collision_box": { "origin": [ -1, 0, -1 ], "size": [ 2, 16, 2 ] },
"minecraft:selection_box": { "origin": [ -1, 0, -1 ], "size": [ 2, 16, 2 ] },
"minecraft:destructible_by_explosion": false,
"minecraft:destructible_by_mining": { "seconds_to_destroy": 0.3 },
"minecraft:geometry": {
"identifier": "geometry.glass_pane"
},
"minecraft:material_instances": {
"*": { "texture": "glass", "render_method": "blend", "ambient_occlusion": 0.0 },
"top": { "texture": "glass_pane_top", "render_method": "blend", "ambient_occlusion": 0.0 }
}
},
"permutations": [
]
}
}
这里我们将玻璃板设置为了防爆。然后规定玻璃板的模型骨骼可见性，这里我们引入minecraft:connection方块特征：
glass_pane.block.json
{
"format_version": "1.26.20",
"minecraft:block": {
"description": {
"identifier": "test:blast_proof_glass_pane",
"menu_category": {
"category": "construction"
},
"traits": {
"minecraft:connection": {
"enabled_states": [ "minecraft:cardinal_connections" ]
}
}
},
"components": {
"minecraft:collision_box": { "origin": [ -1, 0, -1 ], "size": [ 2, 16, 2 ] },
"minecraft:selection_box": { "origin": [ -1, 0, -1 ], "size": [ 2, 16, 2 ] },
"minecraft:destructible_by_explosion": false,
"minecraft:destructible_by_mining": { "seconds_to_destroy": 0.3 },
"minecraft:geometry": {
"identifier": "geometry.glass_pane",
"bone_visibility": {
"north": "q.block_state('minecraft:connection_north')",
"south": "q.block_state('minecraft:connection_south')",
"west": "q.block_state('minecraft:connection_west')",
"east": "q.block_state('minecraft:connection_east')",
"center_north": "!q.block_state('minecraft:connection_north')",
"center_south": "!q.block_state('minecraft:connection_south')",
"center_west": "!q.block_state('minecraft:connection_west')",
"center_east": "!q.block_state('minecraft:connection_east')",
"edge_north": "false",
"edge_south": "false",
"edge_west": "false",
"edge_east": "false"
}
},
"minecraft:material_instances": {
"*": { "texture": "glass", "render_method": "blend", "ambient_occlusion": 0.0 },
"top": { "texture": "glass_pane_top", "render_method": "blend", "ambient_occlusion": 0.0 }
}
},
"permutations": [
]
}
}
现在如果进入游戏，你会在你的创造模式物品栏看到你的玻璃板，并且它们能够正确产生连接模型，然而此时碰撞箱和选择箱还不正常。我们这里就来定义各个方块置换，也就是碰撞箱和选择箱。这里的定义是有点痛苦的事情：
- 首先，玻璃板一共存在 16 种连接状态，也就是分别是否和东南西北连接的状态。我们在根组件已经考虑了均未连接的状态，这样就还有 15 个方块置换等待定义。
- 碰撞箱和选择箱的坐标设定略显诡异，并且会涉及到复合碰撞箱。你可能需要多次
/reload all以得到你心仪的更改。
我们建议可以先指定仅连接到东南西北时的碰撞箱，剩余情况的碰撞箱就是这 4 种情况的叠加了。

最后就是在物品栏内的显示问题了，这需要使用minecraft:item_visual组件。我们把东西模型和东西边缘隐藏掉，然后把中心模型的南北部分也隐藏掉。

最后，再定义一下玻璃板的音效、翻译即可。这套逻辑适用于其他颜色的玻璃板，代码可直接套用。
已知问题
通过这种方法制作的玻璃板可能存在两个问题：
- 对原版其他方块的连接性不太好，尤其是在玻璃板、栅栏、墙连接时，会无法产生正确的连接。
自定义玻璃板（右）没有办法和原版玻璃板（左）正确地产生连接
- 无法像原版的玻璃板一样，靠近后贴图淡化。
