It’s got a minimap, it’s got all your combat and crafting and research and stat systems built for you. To call this an AI solution would be doing it a disservice, this thing has everything you need to make your own survival RPG game, it has ballistics, lots of different weapons, melee and ranged, is has all the systems you need for a game coded in. His long term goal is to allow you to make your own GTA clone, and he’s already halfway there. You can already do it but the process is time consuming, he’s working to streamline it.
#USING UNITY ASSETS IN UNREAL UPDATE#
He’s currently working on big update which will make it a lot easier to spawn in a whole bunch of NPC’s into your city. The same developer also makes Procedural City Generator, and he is very responsive to questions and issues. They also have static and spline based crowds, so if you want a Persona 5 style crowd walking through your levels, they have that. They even have dialogues between each other. They are fully animated, you can plug in your own characters to make whatever you want, they take damage, run, etc. They have points of interest, tasks and behaviors, waypoints, roaming, pathfollowing, go to location, or craft your own custom tasks. It can create complex crowds of characters who are reactive to their surroundings.
NPC Manager is a really good AI solution for Unreal. It is too broad a topic for my 2000 word article to cover in fullness. Much as I am brilliant and good, check out the Unreal Docs for the real scoop on how behavior tree’s work. You can create very complex behaviors with this, right down to:ģ: As combat ensues, spout dialogue at the player while ducking behind cover.Ĥ: Player gets AI down to 30% of life, begin singing songs of victory.ĥ: You are at ten percent of life, walk up to the player and start a dialogue.Ħ: Ask the player to spare you, with a yes/no UI interface.ħ: The player spares you, begin a half hour dialogue tree.Īll of this is feasible without too much difficulty in a behavior tree.
The AI will move down a hierarchical list of behaviors, you can control when and how they move from node to node, you can control what factors manage entry into a node or just skipping it over. You can use the preprogrammed behavior nodes, or you can make your own nodes. Unreal out of the box comes equipped with a fully functional AI system based on behavior trees. There is no shortage of AI solutions on offer, from simple to complex, however, if you do not want to purchase them, you’re not out of luck, not at all. In Unreal, you are spoilt for choice when it comes to AI.
