Bethesda has been the steward of the Fallout franchise for nearly a decade at this point, and Fallout 4 will reportedly be the most detailed game the company has ever made. That’s thanks to an updated version of the Creation game engine, but before Creation, there was Gamebryo. This is the game engine that powered Fallout 3 and New Vegas, and it had an interesting set of quirks. After poking around in the game files, someone on 4chan noticed a fantastic detail — there’s a hat that is literally an entire train.


B社已经在辐射的营销上管了近十年了，辐射4将会B社制作过最具细节的游戏。这得归功于creation引擎的加强。但是在creation引擎之前，gamebryo，用于F3和NV，这个旧引擎有着一套很有意思的特点。有一个闲的无聊的宅男在浏览游戏文件时发现了一个有意思的地方：F3中的火车并不是一个载具，而是一个帽子。。。


Gamebryo was not really designed with vehicles in mind. When you think about it, Skyrim is all horses and walking, but all the cars are wrecked in Fallout, so vehicles don’t come up much. There are a number of workarounds to make vehicles work the few times they appear. For example, the Fallout Vertibirds are just pre-rendered animations that don’t operate inside the physics of the game.


gamebyro并不是一个在设计时就考虑载具的引擎。老滚系列有马，但是辐射中所有的汽车都是陈年老货并且全坏了，所以辐射中交通工具几乎没有。少数出现的交通工具只是预先安排的动画脚本，而不是真正在运行


Far more interesting is the Presidential Metro Train in Fallout 3’sBroken Steel DLC. It turns out it was easier to make the train car a piece of head armor and slap it onto an NPC than it was to make a working vehicle. The NPC (with train hat) can be spawned wherever it needs to be. All you see is the train car on the tracks, but under the surface is a person with a train on her head.


更有意思的是，在F3断钢DLC中的总统列车，那位宅男发现，整俩火车被做成了一个护具（帽子），套在了一个隐藏的NPC头上，来使火车前后运动。。。。（巨汗）。这个NPC（头上套着火车的那个）能够用控制台召唤出来。你在游戏中看到的是一个火车在铁轨上，但是在铁轨下面，则有个NPC头上套着这个火车。。。。 = =



There’s another trick when you actually board the train, and it’salmost as weird. Again, there aren’t physics for making a train car move in the Gamebryo engine, so you’re not actually on the train. Instead, the player is equipped with a piece of head armor that covers the field of view and looks like the inside of a train. Then a camera animation is played that makes it look like you’re on a moving train, but you really just have a helmet on.


还有一个好玩的地方，那就是当你进入火车时，是很奇葩的。我重申一下，gamebyro引擎并不是在物理层面模拟火车，所以你实际上并没有进入火车，而是玩家装备了这个火车帽子，然后帽子盖住了玩家的视野，使玩家觉得我好像在火车里。。。。（狂汗！参考第一张图）然后动画启动，火车前后运动


The new Creation engine in Fallout 4 will be much more sophisticated than Gamebryo from Fallout 3, but they share much of the same DNA. I wouldn’t be surprised to see some clever workarounds in Fallout 4 too, but that’s not necessarily a bad thing. It’s a good solution if it doesn’t introduce any new bugs and can fool the player.
