前言
最近我的糖果大陆附加包涉及到活板门和门的实现，所以这期和下期我们来放出它们的教程。
https://klpbbs.com/static/image/hrline/line5.png
目标
制作一个尽可能与原版一样的活板门，包括可以打开/关闭，可以放置在方块的上面/下面等。
https://klpbbs.com/static/image/hrline/line7.png
分析与解决
今天的任务比之前的液体方块简单得多。首先，既然是活板门，那么它肯定有4个方向；还需要指定放置在方块的上方还是下方；最后，还需要指定它是否打开了。这就是三个方块状态。
活板门的上下取决于它放置在方块的上半部分还是下半部分，所以可以用方块特征里的minecraft:placement_position实现。4个方向是根据我们放置时的朝向决定的，所以使用minecraft:placement_direction实现。至于开关与否，就单独定义一个方块状态。
{
"format_version": "1.20.30", //使用较新的格式版本才可以使用方块特征
"minecraft:block": { //定义一个方块
"description": {
"identifier": "supplementary:chocolate_trapdoor", //方块ID
"menu_category": { //指定方块要放在创造模式物品栏的哪里
"category": "construction", //指定放在建材分类下
"group": "itemGroup.name.trapdoor" //指定放在活板门一组里
},
"traits": { //定义方块特征
"minecraft:placement_position": {
"enabled_states": [
"minecraft:vertical_half" //启用minecraft:placement_position中的minecraft:vertical_half状态，检测放置在方块的上半部分还是下半部分
]
},
"minecraft:placement_direction": {
"enabled_states": [
"minecraft:cardinal_direction" //启用minecraft:placement_direction中的minecraft:cardinal_direction状态，检测放置的4个方向，忽略向上和向下
]
}
},
"states": { //定义方块状态
"supplementary:open_bit": [ //定义一个叫supplementary:open_bit的状态，接受布尔值，默认值为false
false,
true
]
}
}, ...
}
}
然后定义一些基本的方块组件，例如爆炸抗性、光照等。
... "components": {
"tag:stone": {}, //让自定义镐子识别用的标签，所以这个方块用镐子挖掘更快
"minecraft:destructible_by_mining": { //定义可挖掘性
"seconds_to_destroy": 0.5 //需要0.5秒钟破坏
},
"minecraft:destructible_by_explosion": { //定义可被爆炸摧毁性
"explosion_resistance": 1.2 //爆炸抗性为1.2
},
"minecraft:collision_box": { //定义实体碰撞箱，这里是活板门的碰撞箱
"origin": [
-8,
0,
-8
],
"size": [
16,
3,
16
]
},
"minecraft:selection_box": { //定义挖掘判定箱，这里是活板门的判定箱
"origin": [
-8,
0,
-8
],
"size": [
16,
3,
16
]
},
"minecraft:geometry": "geometry.trapdoor", //这个方块要使用活板门的模型
"minecraft:material_instances": {
"*": {
"texture": "chocolate_trapdoor", //由于使用了模型，我们可以直接定义纹理。这里还定义了渲染方法。
"render_method": "blend" //允许透明/半透明，它上面不能放置红石线且不能刷怪，它也不能被红石充能。
}
},
"minecraft:on_interact": {
"event": "toggle"
}, //当我们点击它的时候，活板门会打开或关闭。
"minecraft:light_dampening": 0 //不阻挡光线
}, ...
刚才我们定义了一个事件，用来打开/关闭活板门。事件代码如下。
"toggle": {
"sequence": [ //按顺序执行事件
{
"set_block_state": {
"supplementary:open_bit": "!q.block_state('supplementary:open_bit')" //把“是否打开”的方块状态变为原来的相反值（打开变为关上，关上变为打开）
}
},
{
"condition": "q.block_state('supplementary:open_bit')", //当活板门打开时...
"run_command": {
"command": "playsound close.wooden_trapdoor @a ~~~ 0.9 0.9" //播放关闭木活板门的声音
}
},
{
"condition": "!q.block_state('supplementary:open_bit')", //当活板门关闭时...
"run_command": {
"command": "playsound open.wooden_trapdoor @a ~~~ 0.9 0.9" //播放打开木活板门的声音
}
}
]
}
接下来定义方块排列。
活板门的开关、上下、方向都可以通过旋转实现。可以按三个轴旋转。比如，把活板门打开就是沿Z轴旋转-90度，上下通过沿X或Z轴旋转180度实现，方向通过沿Y轴旋转90/180/-90度实现，等等。
总共有16（4*2*2）个排列，代码太长，请看下面的完整示例。
那么活板门方块就做好了，下面是我的chocolate_trapdoor.json中的代码。{

以下是模型文件。
{"format_version":"1.12.0","minecraft:geometry":[{"description":{"identifier":"geometry.trapdoor","texture_width":16,"texture_height":16,"visible_bounds_width":3,"visible_bounds_height":1.5,"visible_bounds_offset":},"bones":[{"name":"trapdoor","pivot":,"cubes":[{"origin":[-8.01,-0.01,-8.01],"size":,"uv":{"north":{"uv":,"uv_size":[-16,-3]},"east":{"uv":,"uv_size":[-16,-3]},"south":{"uv":,"uv_size":[-16,-3]},"west":{"uv":,"uv_size":[-16,-3]},"up":{"uv":,"uv_size":[-16,-16]},"down":{"uv":,"uv_size":}}}]}]}]}
这里我本来是想通过texture_mesh实现镂空模型效果的，但是由于texture_mesh的texture字段指定的是附着物文档中的键名而不是方块文档中minecraft:material_instances的键名，不能实现这个功能。如果非得实现，模型代码会长很多，所以我还是选择了与原版保持一致。下期讲门的时候，拿在手里的门就是一个附着物，所以可以实现镂空效果。

总结
这一期，我们制作了一个与原版极其相似的活板门。
最后，我放出我为这个活板门做的纹理，以及所有的示例文档，可以参考一下。

世界模板好像是和附加包不同的.mctemplate文件，可以导入一个模板，创建世界时使用，似乎也可以在世界模板中包含附加包（和.mcworld差不多） 嘿，你知道附加包中可以添加世界包(世界模板)吗？是否有了解过其相关内容.. 感谢分享
