# 设计维度传送门
|
||
|
||
在本节中，我们为维度设计一个传送门，我们需要使用自定义方块和模组SDK相配合来完成这一逻辑。
|
||
|
||
## 自定义传送门方块
|
||
|
||
传送门方块是自定义传送门必须的一个方块。我们可以使用`base_block`为`portal`的自定义方块配合`netease:portal`组件来完成这一配置。我们在编辑器中新建两个方块，分别用于传到我们对应的维度和传回主世界。这两个方块的行为包定义分别设置如下：
|
||
|
||
```json
|
||
{
|
||
"format_version": "1.10",
|
||
"minecraft:block": {
|
||
"description": {
|
||
"identifier": "tutorial_demo:custom_dim_gate",
|
||
"base_block": "portal"
|
||
},
|
||
"components": {
|
||
"minecraft:destroy_time": {
|
||
"value": 9999
|
||
},
|
||
"minecraft:loot": {
|
||
"table": "loot_tables/empty.json"
|
||
},
|
||
"minecraft:block_light_emission": {
|
||
"emission": 1.0
|
||
},
|
||
"netease:portal": {
|
||
"target_dimension": 1688560817,
|
||
"particle_east_west": "minecraft:portal_east_west",
|
||
"particle_north_south": "minecraft:portal_north_south"
|
||
},
|
||
"netease:listen_block_remove": {
|
||
"value": true
|
||
}
|
||
}
|
||
}
|
||
}
|
||
```
|
||
|
||
```json
|
||
{
|
||
"format_version": "1.10",
|
||
"minecraft:block": {
|
||
"description": {
|
||
"identifier": "tutorial_demo:custom_dim_gate_back",
|
||
"base_block": "portal"
|
||
},
|
||
"components": {
|
||
"minecraft:destroy_time": {
|
||
"value": 9999
|
||
},
|
||
"minecraft:loot": {
|
||
"table": "loot_tables/empty.json"
|
||
},
|
||
"minecraft:block_light_emission": {
|
||
"emission": 1.0
|
||
},
|
||
"netease:portal": {
|
||
"target_dimension": 0,
|
||
"particle_east_west": "minecraft:portal_east_west",
|
||
"particle_north_south": "minecraft:portal_north_south"
|
||
},
|
||
"netease:listen_block_remove": {
|
||
"value": true
|
||
}
|
||
}
|
||
}
|
||
}
|
||
```
|
||
|
||
其中`netease:portal`中的`target_dimension`分别设置为我们自定义的维度ID和原版的主世界维度ID（0），`particle_east_west`和`particle_north_south`为东西朝向的传送门方块散发的粒子和南北朝向散发的粒子，我们不妨先设置为国际版原版的传送门方块粒子。为了于模组SDK配合，我们将`netease:listen_block_remove`打开。
|
||
|
||
## 设计传送门结构
|
||
|
||
我们这部分代码参考演示示例包portalGateDemo中的代码，并将对应的方块ID和维度ID替换成我们的自己的ID。然后我们一起来分析传送门的代码。事实上，我们如欲设计一个传送门结构，只需要在生成传送门前使用`portal`引擎组件的`DetectStructure`方法来判定是否为我们需要的结构即可。如果是我们的结构，我们就将传送门中的空气替换为我们的传送门方块，如果不是，就什么也不执行。我们这里使用的示例为在荧石框架上使用骨粉来激活传送门，所有的逻辑都在服务端执行。

## 在传送终点生成返回传送门
|
||
|
||
我们的传送门不能有去无回，所以我们还需要在玩家进入对应维度后在终点处生成一个返回的传送门。关于这一功能我们其实分两种情况考虑，第一种是在目标点周围没有发现之前存在的传送门，那么我们应该在目标点附近找一个空旷点生成一个传送门，然后将玩家移动至该传送门生成的位置。另一种情况是目标点附近存在一个传送门，我们只需要将玩家的位置移动到该传送门处即可。我们查看补充完整的服务端脚本文件。
