前言

今天我们继续放出方块的例子。

目标

这次我想制作一种液体，拥有真实的扩散机制，还可以用桶装起来。

分析与解决

没错，今天要做一个液体方块。既然没有说明到底是什么液体，那我就先做着，做完了再说吧。液体这个东西虽然比坩埚难些，但还是可以做出来的。首先，既然是液体，那么必须定义一个方块属性，来决定液体方块的高度。这个例子中，7代表液体源，8代表竖直向下的液体方块，剩下的代表水平扩散的液体方块。 {   "format_version": "1.18.0",   "minecraft:block": {     "description": {       "identifier": "supplementary:viscous_lava",       "properties": {         "supplementary:viscous_lava_liquid_height": [ //一个属性           1,           2,           3,           4,           5,           6,           7,           8         ]       }     }, ...   } } 复制代码 然后定义一些基本的方块组件，例如爆炸抗性、光照等。由于我们定义的属性中，7才是液体源，所以要在玩家放置这个液体方块后把它自身的属性设定为7，不然就无法放置液体源了。 ... "components": {       "minecraft:on_player_placing": {         "event": "on_placed"       }, //玩家放置此方块后触发on_placed事件。       "minecraft:aim_collision": false, //无法被选中       "minecraft:block_collision": false, //没有碰撞体积       "minecraft:geometry": "geometry.liquid_height8", //方块模型       "minecraft:creative_category": {         "category": "construction"       }, //创造模式物品栏分类（可以不加这个组件）       "minecraft:material_instances": {         "*": {           "texture": "viscous_lava",           "render_method": "blend"         }       }, //定义这个方块的纹理。blend决定是半透明纹理，而且不能在它上面刷怪。       "minecraft:destroy_time": 10000000, //无法被挖掘破坏。其实只是挖掘时间特别长而已，在1.19格式版本下可以用  "minecraft:destructible_by_mining": false  来定义这个方块不可被挖掘破坏。       "minecraft:map_color": "#4C4C4C", //地图颜色       "minecraft:block_light_filter": 0, //方块吸光量       "minecraft:block_light_emission": 1, //方块发光量，这里是15级光照亮度       "minecraft:explosion_resistance": 500 //爆炸抗性是500     },     "events": {       "on_placed": {         "set_block_property": {           "supplementary:viscous_lava_liquid_height": 7 //将液体高度设为7，即液体源方块         }       }, ... 复制代码 现在来定义方块排列。   ... {         "condition": "q.block_property('supplementary:viscous_lava_liquid_height')==7", //液体源方块         "components": {           "minecraft:geometry": "geometry.liquid_height7", //液体源方块的模型           "tag:supplementary:viscous_lava_liquid_height7": {}, //这里加一个tag，为了方便以后的判断           "minecraft:ticking": {             "looping": true,             "range": [               0.2,               0.2             ], //速度，这里是每0.2秒散播一次             "on_tick": {               "event": "spread_to_6", //这个事件的作用是在这个方块的周围放置高度为6的液体方块。同理，高度为6的液体方块会放置高度为5的液体方块，直到结束。               "target": "self"             }           }, //液体散播的组件           "minecraft:aim_collision": true //指定了液体源方块可以被选中，这是为了方便以后用桶装液体。         }       }, ... 复制代码 现在我们来看看最难的部分——事件。由于这一部分重复度过高，我不会把所有事件都列出，就拿液体源的事件代码做一个例子吧。   ... "spread_to_6": {         "sequence": [           {             "run_command": {               "command": [                 "execute if block ~1~~ air unless block ~~-1~ air unless block ~~-1~ supplementary:viscous_lava run setblock ~1~~ supplementary:viscous_lava ["supplementary:viscous_lava_liquid_height":6]",                 "execute if block ~-1~~ air unless block ~~-1~ air unless block ~~-1~ supplementary:viscous_lava run setblock ~-1~~ supplementary:viscous_lava ["supplementary:viscous_lava_liquid_height":6]",                 "execute if block ~~~1 air unless block ~~-1~ air unless block ~~-1~ supplementary:viscous_lava run setblock ~~~1 supplementary:viscous_lava ["supplementary:viscous_lava_liquid_height":6]",                 "execute if block ~~~-1 air unless block ~~-1~ air unless block ~~-1~ supplementary:viscous_lava run setblock ~~~-1 supplementary:viscous_lava ["supplementary:viscous_lava_liquid_height":6]",                 "execute if block ~~-1~ air run setblock ~~-1~ supplementary:viscous_lava ["supplementary:viscous_lava_liquid_height":8]",                 "execute if block ~~-1~ supplementary:viscous_lava run setblock ~~-1~ supplementary:viscous_lava ["supplementary:viscous_lava_liquid_height":8]",                 "damage @e[r=0.5] 4 lava"               ] //要运行的一个命令组。前4条负责水平扩散，第5到6条负责竖直扩散，第7条负责造成熔岩伤害。第7条可有可无，甚至可以替换成其他效果。             }           }         ]       }, ... 复制代码 基本上每个液体方块都是以上的逻辑，所以自定义液体其实不难。这些代码还有些缺陷，但我实在想不出既能解决缺陷又不会让游戏卡顿的代码了。 当然了，还需要设计一个能让液体在没有液体源后就消失的功能。在 spread_to_5 事件后，还额外触发了一个 5air 事件，这个事件负责让液体消失，如下。   ... "5air": {         "sequence": [           {             "condition": "!(q.block_neighbor_has_any_tag(1,0,0,'supplementary:viscous_lava_liquid_height7')||q.block_neighbor_has_any_tag(-1,0,0,'supplementary:viscous_lava_liquid_height7')||q.block_neighbor_has_any_tag(0,0,1,'supplementary:viscous_lava_liquid_height7')||q.block_neighbor_has_any_tag(0,0,-1,'supplementary:viscous_lava_liquid_height7')||q.block_neighbor_has_any_tag(1,0,0,'supplementary:viscous_lava_liquid_height8')||q.block_neighbor_has_any_tag(-1,0,0,'supplementary:viscous_lava_liquid_height8')||q.block_neighbor_has_any_tag(0,0,1,'supplementary:viscous_lava_liquid_height8')||q.block_neighbor_has_any_tag(0,0,-1,'supplementary:viscous_lava_liquid_height8'))", //检测周围有没有更高的液体，没有就运行下面的事件方法，有就什么也不做。             "run_command": {               "command": [                 "setblock ~~~ air" //在自身位置放置空气，也就是让自己消失。               ]             }           }         ]       }, ... 复制代码 然后都有规律了，穷举就可以了。最后，随便定义一下这个液体到底是什么。我就叫它黏性熔岩好了。 一番操作猛如虎，我终于做好了一个液体方块。以下代码就是我的viscous_lava.json里写的内容，供大家参考。

等等！虽然我们已经定义了液体的模型和液体的方块文档，但液体不都应该有动态纹理吗？于是，我又在flipbook_textures.json文件里输入了以下代码。 [   {     "flipbook_texture": "textures/blocks/viscous_lava",     "atlas_tile": "viscous_lava",     "ticks_per_frame": 16   } ] 复制代码 然后简单地通过terrain_texture.json给方块纹理。 {   "texture_data": {     "viscous_lava": {       "textures": "textures/blocks/viscous_lava"     }   } } 复制代码 现在来定义一个桶吧！因为不能直接修改原版桶，必须自定义一个桶。我叫它加固的桶。代码稍微有点长，我折叠一下。 {   "format_version": "1.17.0",   "minecraft:item": {     "description": {       "identifier": "supplementary:consolidated_bucket",       "category": "items" //定义物品分类，必须有这一行代码     },     "components": {       "minecraft:icon": {         "texture": "consolidated_bucket"       }, //定义物品纹理       "minecraft:creative_category": {         "parent": "itemGroup.name.diamond"       }, //定义在创造模式物品栏里的位置。       "minecraft:allow_off_hand": true, //允许拿在副手上       "minecraft:on_use_on": {         "on_use_on": {           "event": "test"         }       } //点击方块时触发事件 test 。     },     "events": {       "test": {         "sequence": [           {             "condition": "q.block_neighbor_has_any_tag(0,0,0,'supplementary:viscous_lava_liquid_height7')", //如果被点击的方块是黏性熔岩源，那么...             "run_command": {               "command": [                 "gamerule sendcommandfeedback false", //关闭命令提示                 "setblock ~~~ air", //清除黏性熔岩源                 "clear @p supplementary:consolidated_bucket 0 1", //清除加固的桶                 "give @p supplementary:viscous_lava_bucket", //给予装满黏性熔岩的桶                 "playsound bucket.fill_lava @a[r=5] ~~~" //播放装熔岩的音效               ]             }           }         ]       }     }   } } 复制代码 然后还需要定义一个物品，黏性熔岩桶。由于用minecraft:on_use_on事件时会以这个方块为基准点，所以只能用minecraft:entity_placer来放置一个技术性实体，再让这个实体放置黏性熔岩源方块。 {   "format_version": "1.17.0",   "minecraft:item": {     "description": {       "identifier": "supplementary:viscous_lava_bucket",       "category": "items" //定义物品分类，必须有这一行代码     },     "components": {       "minecraft:icon": {         "texture": "viscous_lava_bucket" //定义纹理       },       "minecraft:creative_category": {         "parent": "itemGroup.name.diamond"       }, //定义在创造模式物品栏里的位置。       "minecraft:allow_off_hand": true, //允许左手       "minecraft:entity_placer": {         "entity": "supplementary:viscous_lava_placer" //放置技术性实体       }     }   } } 复制代码 所以，还需要定义一个新实体。代码略长，我折叠一下。 {   "format_version": "1.10.0",   "minecraft:entity": {     "description": {       "identifier": "supplementary:viscous_lava_placer", //实体ID       "is_spawnable": false, //不可自然生成       "is_summonable": true, //可以被命令召唤       "is_experimental": false //不是实验性实体     },     "components": {       "minecraft:timer": {         "time": [           0.02,           0.02         ],         "looping": false,         "time_down_event": {           "event": "place"         }       }, //放下的0.02秒后触发事件place       "minecraft:collision_box": {         "width": 0.98,         "height": 0.98       }, //碰撞箱是0.98*0.98*0.98个方块大小       "minecraft:damage_sensor": [         {           "cause": "all",           "deals_damage": false         }       ], //让实体不受任何类型的伤害       "minecraft:physics": {} //有物理模拟     },     "events": {       "place": {         "run_command": {           "command": [             "gamerule sendcommandfeedback false", //关掉命令提示             "fill ~ ~ ~ ~ ~ ~ supplementary:viscous_lava ["supplementary:viscous_lava_liquid_height":7] keep", //放置一个黏性熔岩源方块             "give @p supplementary:consolidated_bucket", //给予一个空桶（注：在放置实体时黏性熔岩桶已经被用掉了，所以不用再清除了。）             "playsound bucket.empty_lava @a[r=5] ~~~", //播放倒出熔岩的声音             "tp @s 0 -1000 0", //传送到虚空，避免出现声音和粒子             "kill @s" //使自身消失           ]         }       }     }   } } 复制代码 好了，这就差不多了。上面那个实体是技术性实体，不需要显示出来，因此不用额外定义什么了。下面是我制作的一个配方。 {   "format_version": "1.12",   "minecraft:recipe_shaped": {     "description": {       "identifier": "supplementary:viscous_lava_bucket"     },     "tags": [       "crafting_table"     ],     "pattern": [       "BAB",       "CBC"     ],     "key": {       "A": {         "item": "minecraft:lava_bucket"       },       "B": {         "item": "minecraft:magma_cream"       },       "C": {         "item": "minecraft:obsidian"       }     },     "result": {       "item": "supplementary:viscous_lava_bucket"     }   } } 复制代码

总结

这一期，我们制作了一个液体方块。由于技术性限制，这个液体无法让玩家在内部游泳，这是不可避免的。也出现了一些用脚本赋予状态效果从而游泳的例子，但我不会写脚本，所以没有搬上来。也有一些其他方法，然而它们会导致游戏卡顿，世界区域几乎被冻结，游戏刻极为缓慢等现象。 不管怎样，虽然目前做到原版那种液体是不可能的，但至少我们可以做一个“半液体”。制作这种近似液体的方法有很多，这只是其中一种。 最后，我放出我为这个液体做的纹理，以及所有的示例文档，可以参考一下。 示例文档和纹理.zip (9.47 KB, 下载次数: 7) 2023-3-31 21:54 上传 点击文件名下载附件
