They will also attempt to stay out of the player’s view to minimize interference.
These points are generated by estimating the future position of the player, based on the speed and current heading of the player, to minimize unnecessary repathing and avoid making the bots fall behind.
Bots and PathfindingĮach player has a couple of points that the bots use to follow them. By comparing its current velocity, the enemy’s velocity, the reach of the weapon and time until the currently executed attack would hit the bot can predict whether the currently executing attack is going to hit an enemy and thus perform attacks whilst moving. sweep attacks will be used when surrounded by a large amount of enemies and attacks with armour piercing against armoured foes. Bots will choose which attack to perform based on simplified metadata stored in the currently equipped weapon, e.g. After a set time has passed the bot will stop doing the dodge and movement input.Īttacks.
If the bot is inside of the shape it will be prompted to trigger a dodge and movement input to avoid the attack. Whenever an attack is triggered a time-based shape will be created around the danger zone of the attack. Bots rely heavily on area of effect threat objects when fighting enemies with area-based attacks. Talents and abilities. Last, but not least, we added support for the bots to use talents and career abilities. In order to fight more efficiently against moving targets we also added attack velocity anticipation so that they can start charging a melee attack before reaching a target. While this worked in most cases, it could lead to them being unable to perform certain attacks for weapons whose attack chains differed too much from that of other weapons.įor Vermintide 2 we reworked this so that the bots now have access to the different timings required to perform attack chains of various light and heavy attacks.
Because of this, bots received new behaviour to avoid and escape such dangers.Ĭombat capabilities. Bots had previously no knowledge about the required timings to execute the attack chains of a certain weapon – instead they would perform simple tap or hold inputs in order to perform light or heavy attacks. Pathfinding. Vermintide 2 introduced a lot of new area based dangers, such as warpfire, lamp oil fire, troll bile and vortexes. Compared to when Vermintide 1 was first released back in 2015 a lot has happened with the bots. Features such as the bots being able to pick up and give potions and bombs originated from this period. During the lifetime of Vermintide 1 bots were worked on in chunks of improvements.
