矿车(Minecart)是一种使用铁轨的载具,它可以用来运送物品,动物还有玩家。矿车在游戏中非常实用,能用远快于步行的速度进行长途旅程。同时,矿车也被玩家用于娱乐---比如用高超的轨道铺设和设计来制造的错综复杂的云霄飞车系统。

矿车的摆放方式和其他的方块是一样的(点击右键),但是它们只能放在铁轨上面。放置之后,玩家可以推动它们令它们在轨道上持续滑动。但是矿车不像船,它们并没有浮力,因此不能够用来做水梯。

制作

用以下的方法可以制作出矿车:

材料 输入 » 输出
铁锭

矿车是不可堆叠的。

即使已经放置到铁轨上,矿车是可以破坏还原到携带状态的,这一点在矿车被乘骑时同样适用。 石剑或者更好的剑可以一击破坏矿车,但是会有双倍磨损。 射矿车两箭能够达到同样效果,但是箭会像击中生物时一样地消失。

基础的矿车使用

RideableMinecart

可乘坐的矿车

右键矿车可以乘坐它,坐进去之后玩家是不能动的,所以矿车需要有一个外部的冲击(也可以是动力轨道或者加速器)来启动它。玩家先推动矿车然后迅速地骑上去也是可以用来启动矿车的。

右键矿车可以下车,但是如果头顶上只有一个方格的空隙的话,玩家的头会狠狠地撞在洞顶上并失去半格血。当玩家坐在矿车上面时,他也可以利用环境作用力来用来作为矿车的动力,例如向敌人射箭时差生的反作用力,或者是下坡轨道产生的加速度。

在冲到一段轨道的尽头时,矿车会离开轨道并停留在尽头的普通方块上面,矿车也能在这方块上任意滑动。如果矿车坠落在轨道上,它会滑进这条轨道。坐上下落中的矿车,落地时不会受到伤害。

矿车会被掉落状态的物品挡住。而无论是友善还是攻击性的动物,被无人矿车撞上时都会让这辆矿车停下来,这只生物会同时乘上这辆矿车。如果玩家试图右键乘坐一架有动物在上面乘坐的矿车,他会将上面的动物挤下去。破坏被动物乘坐的矿车也可以将它们赶下去,他们会留在矿车原来的位置上一会儿然后再掉出来。

速度

矿车的物理性质并不真实。

矿车的额定极限速度是X,Y或者Z轴方向上8 米每秒 (1个方块的长度视为1米; 8米每秒=17。89米每小时=28。8公里每小时)。这意味这矿车在两条轴之间斜向行驶会有更快的速度。假设: 一架充分加速的矿车往对角线方向斜向移动时会同时拥有X轴方向8米每秒和Z轴方向8米每秒的分速度,因此其实际速度是对角线方向的11。314米每秒。在这种意义上,对角线方向移动的矿车实际上并不符合计程车几何的路径,而是更适用于欧几内得几何路径。这一点在矿车在下坡轨道上运动是同样适用(上坡亦然,但需要适当的加速以弥补减速度)。

Beta 1。5之后的加速方法

在Beta1。5版之后,游戏里增加了动力轨道和探测器来实现加速,减速和启动矿车的效果。

1。5版之前的加速方法仍然适用,但是Notch表示那些方法将会在1。6版失效。[1]

Beta 1。5版之前的加速方法

当两架矿车相邻时会发生很奇怪的现象-它们会猛然加速。 这个现象过去常常被用来制作加速器: 专门弄一些矿车来为其它从旁经过的矿车提供加速从而实现长距离旅行。 当2架或者更多的矿车并排行驶的时候,它们会加速到速度上限并持续积累能量直到他们不再相邻。

另外一种加速应用是将一架矿车推向另一架矿车,然后两架矿车就会互相加速并同一条轨道上一直运动下去。 可以说,作一次长途旅行只需要两架矿车。 你也可以增加矿车的数量让它们抓住撞上的动物。

上面提到的速度限制是在计算了加速后得到的速度之后得出的。 当一架矿车加速到极速,它会有一个比速度限制更高的"'内部"速度,但是游戏之后会将它的速度限制在最高速。 但是加速系统仍然会对矿车持续输入能量。 这意味着,直到这些从加速积累回来的能量耗光为止,一架充分加速的矿车可以在一条直轨道上以8米每秒的速度持续前进而不减速。

相似的现象发生在有乘客的下坡的矿车上。 一架没乘客的的下坡矿车到达坡底时会快速减速。 因为车的这个"内部"速度和极限速度接近。 换句话说,这个现象会让一架从很高的高度落下来的矿车在到底坡底之后会在短短15米左右的距离停下来。

速度的衰减

一个单位的动能能够定义为矿车沿一个方格的斜度下落一个方格所获得的动能。也可以视为沿一个方格斜度上升一个所消耗的动能。如果一个45度下坡直接连在一个同样的上坡底部,从60高度下落可以回升到40高度。 20单位的势能会被消耗。但是如果两个斜坡相隔20距离,回升高度会是35。这意味着拥有更多能量的矿车会损耗更多的能量。所以一个平缓的斜坡会比一段水平轨道更利于让你进行长途旅行。

任何挡在铁路上的东西都会把矿车停住,包括: 方块,物品以及生物。 矿车离开轨道后,它的速度将以平方骤减。若礦車的速度夠快,是有可能通過缺了一格鐵軌的軌道,減速後繼續在軌道上前進的。生物碰觸礦車對礦車的影響和玩家碰觸礦車相同,例如,生物向著靜止的礦車移動的話,會使礦車開始移動。當移動的礦車撞上生物,該生物會坐進礦車。

如果一台礦車離開了你的讀取範圍,他會暫停在原處,直到當他再度進入讀取範圍,他會依照原本狀態繼續前進。當你離開遊戲時,所有的礦車也會同樣的暫停在原處,直到遊戲再度開啟。 這可能會導致拖延礦車循環的助推器。

Unoccupied Carts,an Incline and a boost

This table shows the distance traveled by an unoccupied minecart on an incline,with a boost (or no boost). The most efficient way is to use only 1 boost at the bottom of the incline on the flat surface. Using 2 will increase by about 20% or 1.5m. All distance trends based on the hight seem to be logarithmic. The carts started from rest,on an incline (at Height).

-Height- No Boost Bottom Bottom and Top All boosts on incline and bottom
1 2.77m 8.77 10.8 10.8
2 4.59m 9.59 10.83 13.37
3 5.81m 9.81 11.66 15.12
4 7.04m 10.04 12.46 16.95
5 7.87m 10.87 12.29 (Yes,it did actually travel less) 17.95
10 11.65m 13.38 15.12 21.68
100 15.87 17.05 17.54 25.34

Detecting Minecarts

The Detector Rail is a switch activated by minecarts. It generates a Redstone charge when a minecart is on the rail. It was introduced in Beta 1.5.

Prior to Beta 1.5,carts were detected by using Pressure Plates in line with cart tracks. This had the often undesirable effect of dramatically slowing or even stopping the minecart,which limited the use of this design mostly to boosters.

Minecarts can also be detected when their corners run over pressure plates as they go around a curved track. The effect is similar to the detector rail,but can only occur at curves.

Collision

Minecarts seems to have about the same size as a block; 1x1. Because of this,a ladder or door will prevent it from falling down a 1x1 hole. This can be utilized to make minecart dispensers,by stacking carts on top of each other and dispensing them with the help of a booster. A single cart dispenser using a door can also be made by using a ladder to block the cart from falling off the door.

Additionally,you can transport carts along 1 block wide water streams without the minecarts falling by placing ladders underneath. By alternating the ladders,items can still fall through. Because streams carry minecarts at a very slow rate,a trap can be made where anyone sitting in a cart will be suffocated in a block directly above the stream,and their items can be collected below. (NOTE: currently this ability of water to push carts is broken as of 1.5. There are indications that this bug will be fixed in a future release.)

Carts on minecart tracks will also ignore collision in certain situations. A cart traveling downhill or on a curve with a block placed in front of it will go through the block. If it is going fast enough,it can skip through one block and reattach to track on the other side,at significantly reduced speed.

Special Minecarts

There are currently two types of special minecarts:

  • Powered Minecart - A self-propelled minecart that is powered by fuel.
  • Storage Minecart - A minecart that can store items like a standard chest.

Minecart Trains

After Friday July 30's Minecart update,creating Minecart trains became a much simpler solution to transporting goods. To create a train,start with a fairly short length of straight track with an open ending on one side. Put a Powered Minecart on the side nearest the open end,and then add Storage Minecarts or ridable Minecarts along the rest of the track. Then,turn on your Powered Minecart. It will push the other Minecarts as if it were a Minecart Train. Placing an additional Powered Minecart on the other end will allow you to make a two-way train,as minecarts currently only push other carts,not pull.

Glitches

Minecart fire pig

A pig inside a burning minecart.

  • Prior to Alpha version 1.2.2,destroying a minecart while riding in said minecart would cause the player to fall through the block below the minecart. This could be used to make secret entrances into bases,though entry in this way caused the loss of half a heart due to a short moment of suffocation. (This bug was apparently fixed,but has since resurfaced in Beta version 1.1_02)
  • Saving and reloading while riding a minecart will leave you stuck in the ground,lowered by one y unit. If you are on a level section of track,jumping will get you out of it; if you are on a slope when this happens,you may be stuck in the ground,suffocating to death. Beta 1.3_01
  • Detonating TNT in close proximity to a minecart,even when doing so with the TNT submerged in water (such as a cannon),will often cause the minecart to disintegrate into numerous dropped minecarts.[2]
  • Minecarts can be set on fire,but the mob or player inside the minecart will not catch fire from a minecart. (Pictured)
  • If you are sitting in a boat,minecart,saddled pig or saddled pig in a minecart while entering or exiting the nether the game will crash.
  • If there is a saddled pig in a minecart in a two block high space and you get on it you will slowly suffocate to death and be able to see under the ground
  • Riding a saddled pig in a minecart creates a self propelling booster.[3]
  • If you are riding a minecart through any opening only wide enough for the minecart to pass through,(1x1,) you will pass through as well,but take suffocation damage.
  • When placing a minecart on a track in SMP,touching the minecart at all will cause it to glitch,creating a solid,unmovable minecart,and a ghostly cart that seems to move freely. After a short while,the game will crash. (This issue has been fixed as of Nov 10,2010 in Minecraft Alpha v1.2.2 and partially fixed in Minecraft Server 0.2.4. The Minecraft Server Update 0.2.5 seemed to give the ability to now destroy minecarts with any tool,although the minecart is not animated when being hit.)
  • 2 minecarts placed on the same circular track will run forever.
  • As of Beta 1.5 water will not put out flaming minecarts.
  • Sometimes empty minecarts will duplicate while on rails.

琐事

  • 在Beta 1.5更新后,矿车似乎更容易打烂了。这是因为拳头的伤害增加了。
  • 矿车好像是浮在铁轨上的,这是因为它的模型没有轮子。
  • 猪坐在矿车上时是可以骑的,但需要。 这将给你一个会自己走的矿车.
  • 史莱姆老是跟着你,直到你烦得把它打死?脑筋转个弯,它就会你后面帮你推矿车。这个策略非常有用,还能用来加速一长串矿车。[4]
  • 你可以把一只中型史莱姆塞进矿车,它就打不到你了。但是,大的可以。
  • 大型史莱姆在矿车里会完全把矿车挡住---你只看见一只动不了的大史莱姆。
  • 矿车中的中型史莱姆周围会有一股“力场”,可以把你推开,不过不会受伤。
  • 若史莱姆在矿车中被打死会分裂。因为它们不能动,所以这不失为分裂史莱姆的方法。
  • 运输矿车没有出现之前,矿车是会自动收集掉下的物品的。
  • 在轨道上的掉落的物品或骷髅射出的箭会像墙一样卡停矿车。
  • 被驯服的会跟着你在矿车后跑。
  • 如果在矿车上查看自己的物品栏,你就会变成在空中坐着的样子。

    The appearance of the inventory while in a Minecart.

  • 矿车的材质文件(cart.png)显示有一个“皮革般”的仪表板,大小和矿车底差不多。但是这部分材质没有被使用。
  • 末影人不能通过传送离开矿车。
  • The upper has not yet been implemented as Minecarts can only be placed on rails and falling in lava while in a Minecart will destroy it and the player will fall in the lava.
  • 蜘蛛可以被困在矿车里。动力矿车不能推动蜘蛛,但玩家和充能铁轨却可以。蜘蛛不能离开矿车,但是可以环顾四周。
  • 若有充能铁轨驱动和空气补给,矿车也可以在水下运行。
  • 骷髅困在矿车里面,它会像蜘蛛骑士一样坐下。
