前言
对于大部分人，门确实是一个难复刻的东西。它的难度不在于门的方向或者开关之类，而在于它是一个两格高的方块。门的这种性质注定了它需要一番功夫制作，“活板门”和“门”也花了我一天时间来研究。其中，有半天时间都在优化门的两格高带来的极差的体验。

目标
制作一个尽可能与原版一样的门，可以打开/关闭。

分析与解决
今天的任务比之前的门要更难，但也不是无法解决。首先，既然是门，那么它肯定有指定4个方向的状态，还有指定是否打开的状态。
门的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。
不过我们使用了方块特征，就把相关的触发器组件——例如minecraft:on_placed——给占用了，以后我们不能用这些组件了。不过根据我的测试，minecraft:on_player_placing似乎还可以使用，这是以后的关键。
现在我们来定义方块状态和一些基本的组件。
{
"format_version": "1.20.60", //格式版本
"minecraft:block": {
"description": {
"identifier": "supplementary:chocolate_door", //方块ID
"menu_category": { //定义菜单分类
"category": "construction", //在创造模式物品栏的“建材”类里
"group": "itemGroup.name.door" //在“门”物品组里
},
"traits": {
"minecraft:placement_direction": {
"enabled_states": [
"minecraft:cardinal_direction"
]
}
}, //定义方块特征，启用minecraft:cardinal_direction方块状态
"states": {
"supplementary:open_bit": [ //门是否打开
false,
true
],
"supplementary:upper_block_bit": [ //门是否为上半部分
false,
true
], ...
}
},
"components": {
"tag:door": {}, //门的标签
"minecraft:selection_box": { //定义判定箱和碰撞箱
"origin": [
-8,
0,
-8
],
"size": [
16,
16,
3
]
},
"minecraft:collision_box": {
"origin": [
-8,
0,
-8
],
"size": [
16,
16,
3
]
},
"minecraft:destructible_by_mining": { //定义挖掘时间
"seconds_to_destroy": 0.8
},
"minecraft:on_player_placing": {
"event": "placed"
}, //定义触发器，当玩家放置时，触发placed事件
"minecraft:destructible_by_explosion": { //定义爆炸抗性
"explosion_resistance": 2
},
"minecraft:light_dampening": 0 //定义遮光量为0（完全透光）
}, ...
}
}
为了实现两格高方块的效果，我们放置门时只放置了下半部分，需要一个事件把上半部分也放置出来。
"events": {
"placed": { //刚才定义的事件
"set_block_at_pos": { //事件方法：在x y z位置放置方块
"block_type": "supplementary:chocolate_door", //放置巧克力门
"block_offset": [ //在上面一格的位置
0,
1,
0
]
}
}, ...
然后定义门旋转和开关相关的方块排列。给每个排列都加上一个标签，方便后续检测。

{
"block_filter": [

}
]
}
}
}, ...
] ...
但现在有个问题，那就是点击门时只会开半扇门，不会开一整扇门。为了实现这个功能，我们要加上一个循环执行的事件，来不停地检测上面下面的门的状态，并将自身的状态与其同步。我们顺便把开门关门的事件写出来。
"set_door_states": { //检测
"sequence": [
{ //从这个开始，这8个事件方法都将门的方向进行同步
"condition": "q.block_neighbor_has_all_tags(0,-1,0,'door_south','door_lower')",
"set_block_state": {
"supplementary:upper_block_bit": true,
"minecraft:cardinal_direction": "'north'"
}
},
{
"condition": "q.block_neighbor_has_all_tags(0,-1,0,'door_north','door_lower')",
"set_block_state": {
"supplementary:upper_block_bit": true,
"minecraft:cardinal_direction": "'south'"
}
},
{
"condition": "q.block_neighbor_has_all_tags(0,-1,0,'door_east','door_lower')",
"set_block_state": {
"supplementary:upper_block_bit": true,
"minecraft:cardinal_direction": "'west'"
}
},
{
"condition": "q.block_neighbor_has_all_tags(0,-1,0,'door_west','door_lower')",
"set_block_state": {
"supplementary:upper_block_bit": true,
"minecraft:cardinal_direction": "'east'"
}
},
{
"condition": "q.block_neighbor_has_all_tags(0,-1,0,'door_south','door_upper')",
"set_block_state": {
"supplementary:upper_block_bit": true,
"minecraft:cardinal_direction": "'north'"
}
},
{
"condition": "q.block_neighbor_has_all_tags(0,-1,0,'door_north','door_upper')",
"set_block_state": {
"supplementary:upper_block_bit": true,
"minecraft:cardinal_direction": "'south'"
}
},
{
"condition": "q.block_neighbor_has_all_tags(0,-1,0,'door_east','door_upper')",
"set_block_state": {
"supplementary:upper_block_bit": true,
"minecraft:cardinal_direction": "'west'"
}
},
{
"condition": "q.block_neighbor_has_all_tags(0,-1,0,'door_west','door_upper')",
"set_block_state": {
"supplementary:upper_block_bit": true,
"minecraft:cardinal_direction": "'east'"
}
},
{ //从这个开始，这2个是将门的开关状态进行同步，防止只开半扇门的情况发生
"condition": "q.block_neighbor_has_all_tags(0,-1,0,'door_open') || q.block_neighbor_has_all_tags(0,1,0,'door_open')",
"set_block_state": {
"supplementary:open_bit": true
}
},
{
"condition": "q.block_neighbor_has_all_tags(0,-1,0,'door_close') || q.block_neighbor_has_all_tags(0,1,0,'door_close')",
"set_block_state": {
"supplementary:open_bit": false
}
}
]
},
"door_open": { //开门时...
"set_block_state": {
"supplementary:open_bit": "!q.block_state('supplementary:open_bit')" //将门的开关状态设为另一个（开设为关，关设为开）
},
"run_command": {
"command": "playsound open.wooden_door @a ~ ~ ~ 0.4 1.0" //发出声音
}
},
"door_close": { //关门时...
"set_block_state": {
"supplementary:open_bit": "!q.block_state('supplementary:open_bit')" //将门的开关状态设为另一个（开设为关，关设为开）
},
"run_command": {
"command": "playsound close.wooden_door @a ~ ~ ~ 0.4 1.0" //发出声音
}
}, ...
问题又来了，每次开关门有概率“失败”。具体情况是，我们如果开/关门，那么开门后有可能会被同步回没有开/关门的状态，所以视觉上就是门开了一瞬间又关上了。为了解决这个问题，我们需要定义新方块状态，决定门是否同步，一般是要同步的，点击门后设置为不同步，然后再设置回去。
"supplementary:should_update": [ //门是否同步
true,
false
]
{
"condition": "q.block_state('supplementary:should_update')==false",
"components": {
"minecraft:queued_ticking": {
"looping": true,
"interval_range": [
1,
1
],
"on_tick": {
"event": "update",
"target": "self"
}
}
}
}, //如果门不同步，那么等待1刻，然后继续同步
{
"condition": "q.block_state('supplementary:should_update')==true",
"components": {
"minecraft:queued_ticking": {
"looping": true,
"interval_range": [
1,
1
],
"on_tick": {
"event": "set_door_states",
"target": "self"
}
}
}
} //如果门同步，那么触发同步的事件set_door_states
"door_open": {
"set_block_state": {
"supplementary:open_bit": "!q.block_state('supplementary:open_bit')",
"supplementary:should_update": false //开门时，将门设为不同步
},
"run_command": {
"command": "playsound open.wooden_door @a ~ ~ ~ 0.4 1.0"
}
},
"door_close": {
"set_block_state": {
"supplementary:open_bit": "!q.block_state('supplementary:open_bit')",
"supplementary:should_update": false //关门时，将门设为不同步
},
"run_command": {
"command": "playsound close.wooden_door @a ~ ~ ~ 0.4 1.0"
}
}, ...

但是这时，我发现原版门的物品使用了不同的纹理，不好看，实现起来也比较麻烦。于是，我打算做一个附着物，手持“门”时显示。之前我讲过这个，不再赘述。
首先制作模型。
{"format_version":"1.16.0","minecraft:geometry":[{"description":{"identifier":"geometry.door_render","texture_width":16,"texture_height":16,"visible_bounds_width":3,"visible_bounds_height":3.5,"visible_bounds_offset":},"bones":[{"name":"door_root","binding":"q.item_slot_to_bone_name(c.item_slot)"},{"name":"lower","parent":"door_root","pivot":,"cubes":[{"origin":[-8,-16,-8],"size":,"uv":{"north":{"uv":,"uv_size":},"east":{"uv":,"uv_size":},"south":{"uv":,"uv_size":},"west":{"uv":,"uv_size":},"down":{"uv":,"uv_size":[-16,-3]}}}]},{"name":"upper","parent":"door_root","pivot":,"texture_meshes":[{"position":,"rotation":,"local_pivot":,"scale":,"texture":"upper"},{"position":,"rotation":,"local_pivot":,"scale":,"texture":"upper"},{"position":,"rotation":,"local_pivot":,"scale":,"texture":"upper"}]}]}]}
然后是附着物和动画。
