該頁面頁面介紹了地圖的製作方法,及其跟隨玩家在世界中的移動而自動繪製的方式。該頁面還介紹了地圖的局限性以及潛在陷阱,例如按 Shift 鍵立即製作一組地圖無實際意義,因為它們的內容都是完全相同的。
地圖集
建立地圖集的時候有兩種不同的方法:一種是,建立新地圖之前行走到目前地圖的邊緣處,這樣可節約建立地圖的資源,地圖的重疊部分降低到最低。另一種是,謹慎確保地圖的重疊,這樣在多張地圖上尋找相同的目標將輕而易舉,可以知道地圖之間的相對關係。
地圖縮放功能在駭人更新(1.4.2)之後加入遊戲,使得讓0級(初始)到3級的地圖故意重疊的辦法變得沒什麼好處,因為縮放到下一個等級的時候,兩張地圖就可以恰好的銜接在一起。1.8之後因為地圖不再以玩家為中心生成而是對齊到相應的網格中去,因此建立彼此恰好銜接的地圖變得更容易,儘管有玩家不喜歡這樣。
地圖基礎
不管你使用的是什麼方法,在你建立地圖時,這知識對你來説是有用的。例如,你想建立一個「地圖#0」(其實我一直在糾結是否要把地圖命名為「Map_0」)在你想要覆蓋的區域上。當地圖被製作出來後(中心放指南針,周圍8格放紙),它們是「空白地圖」(ID是395)。拿着一張空白地圖,右鍵點擊就可以啟動它(ID是358),並且會顯示出以你為中心,半徑100~120格的地區的地形。縮放級別為0的地圖長度與寬度都為128格,佔地面積也就是128×128格。因此,如果你在或是接近中心塊,那麼顯示出來的範圍幾乎可以覆蓋整張地圖。
如果你想要保留這個地圖,你可以複製它。在你的背包裡的製作區域或工作台裡,擺上一張需要被複製的地圖和一張「空白地圖」就可以完成複製。將一張縮放級別為0的地圖放在工作台中間,周圍圍一圈紙,那麼一張縮放級別為1的地圖便會被製作出來。這張地圖將佔地256×256格,標籤也會變為「地圖#1」(假設沒有地圖在此期間建立)。
這種步驟可以再重複進行3次,從而獲得「地圖#2」(512×512)、「地圖#3」(1024×1024)以及「地圖#4」(2048×2048)
繪製地圖
(下面的編號假定你建立的只有這裏討論的地圖,而不是其他人建立的地圖)
首先,移動到距離x軸與z軸原點64格的矩形範圍內(説清楚點就是x軸和z軸座標都在64以內)並啟動一個空白地圖(「地圖#0」)。用上述的方法(在「地圖基礎」板塊裏面介紹了)將其縮放級別擴張為1(「地圖#1」),繼續啟動後再用上述方法建立一張縮放級別為2的地圖(「地圖#2」),繼續該步驟複製擴展至縮放級別為3(「地圖#3」)的地圖。此時的地圖(「副本地圖#3」)和複製後並繼續擴大的地圖(「地圖#4」)可以展示給你一張總覽圖,巨大的範圍也可以為你的探索提供方向。
建立一些縮放級別為3的地圖也可以更好的顯示結構,你應該向北移動到距離座標(0,y,1024)64格的範圍內,在這裏用一個空白地圖建立一個新的縮放等級為0的地圖(「地圖#5」),然後縮放至縮放級別為3的地圖(「地圖#8」)並保留它。然後向東移動到距離座標(1024,y,1024)64格內,繼續建立新地圖(「地圖#9」)並擴大到3級(「地圖#12」),將其保留下來。就這樣按順時針方向,向南到座標(1024,y,0)並重複此過程,以此類推:
| map # | x-coord | z-coord | relative position |
|---|---|---|---|
| Map #16 | 1024 | 0 | E, 3:00 |
| Map #20 | 1024 | 1024 | SE, 4:30 |
| Map #24 | 0 | 1024 | S, 6:00 |
| Map #28 | -1024 | 1024 | SW, 7:30 |
| Map #32 | -1024 | 0 | W, 9:00 |
| Map #36 | -1024 | -1024 | NW, 10:30 |
You will now have nine zoom-level 3 maps which cover completely the territory shown by the zoom-level 4 overview map. The set of 9 zoom-level 3 maps actually cover 512 blocks beyond the zoom-level 4 map. Each will be centered on the border of the zoom-level 4 map (and four of which will be centered on the corners of the level-4 map). You can, of course, retain any of the intermediate maps by duplicating them before you zoom them. If you don't duplicate before zooming, you won't be able to obtain them again without using server commands (e.g., "/give <player> 358 1 <map#>", where "358" is the data value for a map and 1 is the number of maps to give) or inventory editors.
追蹤地圖的相對位置
It's helpful to keep track of the relative positions of the maps. A useful method of displaying the map set is to craft 10 Item Frames and place them on a wall in a 3-by-3 square with the tenth atop or beside the square. Place the zoom-level 4 overview in the tenth item frame. Place the nine maps in their appropriate positions in the 3×3 square. A sign can be added which identifies the origin and perhaps the corner coordinates. You could also duplicate any of these which you wish to carry with you while fully exploring an area. Information added to one copy will be automatically updated to all other copies. (Note that crafting a second map of the same area—not duplicating, but crafting anew—will create a map that is NOT linked to the original version, and it will thus NOT be updated even though it covers exactly the same area.)
Set of maps in item frames
In the illustration, the sign provides the map # of each of the maps shown. Map #127 is the center map. Map #185 is the map to the north, #189 to the right of that, and the numbering continues clockwise.
As another option, use a chest, and store the maps in slots in the chest that correspond with their in-world positions. If you use this trick, be careful to put them back in the right place once done with them.
You could also craft a Book & Quill (data value 386) in which you can write descriptions of what the map-set covers. This is a useful place to make notes of interesting spots found on those maps. That Book & Quill can be placed in an item frame next to the map set.
避免重疊
Following the Pretty Scary Update, zoom-level 0 maps will not overlap—they are created with each center 128 blocks from each other center. Since the center-most map has an origin of 0,y,0, each zoom-level 0 map has an x-coordinate and z-coordinate which are each a multiple of 128. All maps created within 64 blocks of a particular pre-defined center will be identical.
Overlapping zoom-level 1 maps
Higher zoom-level maps can overlap one another because they can be crafted from zoom-level 0 maps that are centered only 128 blocks from each other. A zoom-level 1 map, for example, covers 256×256 blocks. So if you create a zoom-level 1 map from a zoom-level 0 map centered on (128,y,128)--which would cover a square bounded by the points (64,y,64)-(192,y,64)-(192,y,192)-(64,y,192)--the zoom-level 1 map will cover a square bounded by the points (0,y,0)-(256,y,0)-(256,y,256)-(0,y,256). The zoom-level 0 map adjacent (to the east) would be centered at (256,y,128) and described by the four points (192,y,64)-(320,y,64)-(320,y,192)-(192,y,192). A zoom-level 1 map crafted from this second zoom-level 0 map would be described by the points (128,y,0)-(384,y,0)-(384,y,256)-(128,y,256). The left half of this second zoom-level 1 map will overlap the right half of the first zoom-level 1 map. The illustration on the right may help.
To keep zoom-level 1 maps from overlapping, ensure that each is built from a zoom-level zero with x- and z-coordinates that are multiples of 256. To keep zoom-level 2 maps from overlapping, build them from zoom-level 0 maps with x/z coordinates that are multiples of 512. Zoom-level 3 maps should only be crafted from zoom-level 0 maps centered on x/z coordinates that are multiples of 1024; and zoom-level 4 maps should be crafted from zoom-level 0 maps with x/z coordinates that are multiples of 2048.
Tip: Mark the center of maps by placing a sign labeled it with the map number, and light it up or mark it in some way so that it's easier to find again. Additionally, craft a duplicate map and place it in a frame at that spot. The map (or its duplicate) will display with a green pointer shown at the location of the item frame.
Tip: Surface lava pools make good landmarks as they show up as red dots on zoomed-out maps. The higher the zoom-level, however, the larger the pool must be before it shows up. You can, of course, make your own lava pool, just be sure it is open to the sky. I have built them in "martini glasses" to avoid falling into them and to make them easy to find at night.
