开始接触新自定义方块

打开MCStudio，使用关卡编辑器就可以直接新建一个自定义方块，非常的方便；但是，我们打开文件可以看到，方块的行为放在netease_blocks文件夹内，这里主要存放中国版特色的自定义方块，随着版本的更新，原版Add-on的自定义方块也可以实现很多有趣的功能，所以本章将全面展开介绍新自定义方块的概念的用法并制作地图的农作物、家具。

认识自定义方块

中国版特色的自定义方块存放在netease_blocks文件夹内，而1.16+的新自定义方块写法需要放在微软的blocks文件夹内。

什么是方块属性

方块属性是1.16版本后新写法的“特色”之一：properties，里面可以存放很多属性，其实属性就是数组，用于引擎判断，利用方块属性可以做的很多有趣的功能，比如将方块做成农作物并判断其生长年龄；图中的farm:age和farm:growth就是判断农作物的。

{
    "format_version": "1.16.100",
	"minecraft:block": {
		"description": {
			"identifier": "farm:whiteradish",
            "register_to_creative_menu": true,
			"properties": { //方块属性
				"farm:age": [0, 1, 2],
                "farm:growth": [0, 1, 2, 3, 4, 5]
			}
		},
        "permutations": [···],
        "events": {···},
        "components": {···}
	}
}

使用query.block_property可以获取方块的属性值

"query.block_property('farm:age') == 0"

什么是方块事件

想要灵活的修改方块的行为，需要事件的配合：events。比如当玩家站在方块上的时候，修改方块的掉落物；我们就需要在方块的组件里添加触发器，并且在events内添加响应的事件。

{
	"format_version": "1.16.100",
	"minecraft:block": {
		"description": {
			"identifier": "farm:my_block"
		},
		"components": { //方块组件
			"minecraft:on_step_on": { //触发器，当站在方块上的时候
				"event": "farm:drop_loot", //触发此事件
				"target": "self"
			}
		},
		"events": { //方块事件
			"farm:drop_loot": { //上方触发器触发的事件
				"spawn_loot": { //添加方块的掉落物
					"table": "loot_tables/blocks/my_loot_table.json"
				}
			}
		}
	}
}

什么是方块组合

方块组合可以根据不同的条件应用于具有MoLang表达式的方法，可以非常自由的调配方块的各种组件，实现很多功能；图中的组合分别添加了不同的MoLang表达式条件，就是当方块属性的farm:age为特定值的时候，将下方components里的组件加到这个方块中。

{
    "format_version": "1.16.100",
	"minecraft:block": {
		"description": {
			"identifier": "farm:whiteradish",
            "register_to_creative_menu": true,
			"properties": {···}
		},
        "permutations": [ //方块组合
	  		{
				"condition": "query.block_property('farm:age') == 0", 
				"components": {···}
	  		},
            {
				"condition": "query.block_property('farm:age') == 1",
				"components": {···}
	  		},
            {
				"condition": "query.block_property('farm:age') == 2",
				"components": {···}
	  		}
        ],
        "events":{···},
        "components":{···}
    }
}

什么是方块标签

方块标签可以将不同的方块分组归类，并通过标签获取使用；我将**"tag:farm_plant"**这个标签添加到不同的方块上，当我想要在其它文件中使用或查询的时候，就可以应用这个标签。

{
    "format_version": "1.16.100",
	"minecraft:block": {
		"description": {
			"identifier": "farm:whiteradish",
            "register_to_creative_menu": true,
			"properties": {
				"farm:age": [0, 1, 2],
                "farm:growth": [0, 1, 2, 3, 4, 5]
			}
		},
        "permutations": [···],
        "components": {
            "tag:farm_plant":{} //方块标签
		},
        "events": {···}
	}
}

可以获取方块标签的表达式：

• query.all_tags
• query.any_tag
• query.block_has_all_tags
• query.block_has_any_tag
• query.relative_block_has_all_tags
• query.relative_block_has_any_tag
