一、地下输送带
请用记事本打开游戏目录底下 \data\base\prototypes\entity\entities.lua 档案
1、一般地下输送带
请搜寻 max_distance
将后面的数值5，改成你要的数值
(注意！最大值只可到255，数值超过255，输送距离会失效！)
2、高速地下传送带
请搜寻 fast-transport-belt-to-ground
搜寻结果如下，请对照查看：
type = "transport-belt-to-ground",
name = "fast-transport-belt-to-ground",
icon = "__base__/graphics/icons/fast-transport-belt-to-ground.png",
flags = {"placeable-neutral", "player-creation", "fast-replaceable-no-build-while-moving"},
minable = {hardness = 0.2, mining_time = 0.5, result = "fast-transport-belt-to-ground"},
max_health = 60,
corpse = "small-remnants",
underground_sprite =
请插入 max_distance = 255, 在下面两行之间。
corpse = "small-remnants",
underground_sprite =
插入后的效果是：
corpse = "small-remnants",
max_distance = 255，（逗号也要加上去）
underground_sprite =
3、超高速地下输送带
请搜寻 express-transport-belt-to-ground
方法同上面一样，自行插入字串 max_distance = 255,
二、地下管道
请用记事本打开游戏目录底下 \data\base\prototypes\entity\demo-entities.lua 档案
搜寻 max_underground_distance 字串
将后面的数值10，改成你要的数值
(注意！最大值只可到255，数值超过255，游戏会崩溃！)
