《骑马与砍杀2：霸主》开发日志（132）——战略AI

贤狼赫萝

Greetings warriors of Calradia

卡拉迪亚的战士们，大家好！


The continent of Calradia is a hive of activity. From small bandit parties preying on merchant caravans to huge armies embarking on campaigns, Bannerlord’s dynamic sandbox campaign presents players with an ever-changing, albeit hostile, medieval world. And no matter if players directly involve themselves in unfolding events or if they simply watch on, the kingdoms, clans, and lords vying for power press on with their own ambitions and goals in mind.

卡拉迪亚大陆生机勃勃。从土匪小部队狩猎商队，到大军进行大规模战役，《霸主的》动态沙盒战役给玩家呈现了一个变幻无穷，充满敌意的中世纪世界。无论玩家是直接参与到正在进行的事件，或者只是观望国家，家族，领主之间因野心和目标所导致的的争权夺利。

In this week’s blog, we take a look at one aspect of Bannerlord’s campaign AI that helps to support this idea of a living, breathing world, ensuring that lords make sensible choices and prioritise their actions on the campaign map in a logical way that accounts for their abilities, limitations, and needs.

在这周的日志里，我们会观察《霸主》的战略AI，这能帮助我们了解一个生机勃勃的世界，确保领主们能做出明智的选择，并根据他们的能力，限制和需求来考虑他们在战略地图上的行动的优先权。
Just like the player, NPC lords spend much of their time traversing the campaign map as they go about their business. And unlike our previous game, Mount & Blade: Warband, in Bannerlord, NPC lords are bound by many of the same restrictions and rules as the player. This change in approach to NPC parties meant that we needed to ensure that NPC lords not only create and react to events in the world but can also perform many of the actions that players are required to do to maintain their party and ultimately progress through the game.
和玩家一样，NPC领主们会花大量时间来游历战略地图来做展开他们的事务。不像前作《骑马与砍杀：战团》，在《霸主》重，NPC领主会受到许多与玩家相同的限制和规则的约束。这个变化方式对NPC部队意味着我们需要确保NPC领主们并不只会制造和反应事件，而是也能和玩家一样需要在整个游戏中用各种行动来维持他们的部队。To find an appropriate solution, we first had to consider the different factors that would be important when making these kinds of decisions. The first (and only consistent factor across all possible actions) is the distance that the party would need to travel to perform the action. Naturally, the NPC lord will generally favour closer targets, providing its requirements can be met, of course. In addition to this, the NPC lord will also look at several other factors when deciding which action to select and how to carry that action out.
我们首先要考虑的是做出决策时的不同因素。首先（也是所有行动唯一一致的因素）就是部队需要去目的地的展开行动的距离。通常来说，NPC领主们会选择更近的地方这是肯定的。此外，NPC领主们也会考虑其他几个因素来决定如何行动并执行。

Go To Settlement
NPC lords will need to visit settlements to restock their supplies, recruit fresh troops and ransom prisoners. Lords may also decide to visit a settlement, especially if it is one of their own, if they have been out in the field for some time. After all, even NPCs deserve a little rest and recuperation! If a friendly settlement looks to be being threatened, an NPC lord may decide to lend their support to the settlement to try and dissuade the enemy from attacking, or if need be, defend it.

前往聚落

NPC领主们需要查看聚落的补给，招募生力军和卖俘虏。领主们也会去查看一个聚落，尤其是他已经有段时间没去自己的封地巡视了。总之，即便是NPC也需要休养生息！如果友军聚落被威胁了，NPC领主会伸出援手支援该地，试图赶跑敌人，有必要的话还会参与防御。

Patrol Around a Settlement
If a party’s needs have been met, and there aren’t any other pressing matters to attend to, NPC lords will lead their troops on a patrol around their clan’s settlements, prioritising ones where hostile troops have been spotted in the vicinity of recently.

聚落附近巡逻

如果部队的需求都满足了，而且还没有其他紧要的事情。NPC领主会带领部队巡逻家族的封地，尤其是有敌对势力来过的敌方附近。

Defend a Settlement
NPC lords will ride to the defense of settlements when the need arises, either with just their party in tow or at the head of an army. If the besieged settlement is particularly prosperous or is owned by the NPC lord, then they will be much more likely to make an effort to defend the settlement.

防御聚落

当有需要时，NPC领主会守卫一个聚落，要么是他们的部队就被围困在里面，要么就是带领一支大军。如果聚落特别繁荣或者是NPC的封地，那么他们就更有可能会去参与防御。


Raid a Settlement
Wars aren’t won on the defensive and under the right circumstances they can be quite fruitful. NPC lords, given the opportunity, will try to get in on the action! When looking at enemy settlements, the lord will check to see how valuable the production of the settlement is, as well as, the strength of the settlement. In addition to this, the lord will consider the relations between their clan and that of the owner of the settlement, favouring to attack ones that they are feuding with. Finally, a lord may decide to raid a settlement that is providing supplies to a connected castle, with the castle being the true target of the action.

劫掠聚落

战争不是靠防御赢出来的，而在适当的情况下，战争能让人大发横财。NPC领主如果有机会的话也会这么做！在看到敌人聚落时，领主会查看这个地方的生产价值，以及该地的防御力量。此外，领主还会考虑他们家族和该地所有者的关系，而他们会倾向于袭击与自己有仇的人的封地。最后，领主还会决定坚壁清野，断绝真正目标城堡的补给线。


Besiege a Settlement
NPC lords will try to lay siege to enemy castles when they are confident that they can succeed with the attack. While looking for a suitable target, Warband veterans will be pleased to hear that one factor that is checked is the proximity of the targeted castle to their own faction’s territory, which should help reduce the chances of those crazy expeditions deep into enemy territory to capture a castle they have little chance of holding on to. In addition to this, the strength of the castle is looked at in relation to the lord’s party strength, the prosperity of the castle, as well as, any enemy parties that are known to be in that region at the time.

攻城略地
当NPC领主认为自己的成功率很高时就会攻打敌军城堡。而在寻找何时目标是，《战团》的老玩家会很高兴地知道，攻打敌军城堡的一大因素时自家领地到目标城堡的距离，也就减少了八百里深入敌境内，结果自己几乎没能坚持下去的情况。除此之外，还要根据领主的部队势力，城堡的繁荣度，还有该地区的已知敌方势力。

Chase an Enemy Party
The final aggressive action that an NPC lord can pursue is to chase down enemy parties. If the enemy party is already being chased down then the lord may decide to safely ignore a particular party, however, if a hostile force is considered to be encroaching within the lord’s faction’s territory, especially if they advance near to a settlement, then the lord may decide to give chase. However, with that being said, a lord won’t foolishly chase after a party that it knows to be faster than their own party, at least not for an extended period. Finally, if an enemy party’s clan has low relations with the lord’s clan, then they might be seen as more of a desirable target that is worth giving chase to.

追击敌军

NPC的最终攻击行为是追击敌人。如果敌人正被追赶，那么领主会决定是要忽略某支部队来省点麻烦。但是如果敌军正侵犯领主阵营的领土，尤其是他们在靠近聚落是，那么领主就会去追击。然而话虽如此，领主不会蠢到追一个比自己跑得还快的人，至少不会追很久。最后，如果敌方家族和领主家族关系恶劣，那么他们就会更渴望追击到目标。
