🧠 In Unreal an NPC, even if it's really dumb, needs a brain to accomplish the simplest actions anyway. We can build up its brain by a Behavior Tree, a network of nodes to decide when it starts a new action.

Nowadays, with Unreal we can create NPCs controlled by AI systems to chase relentlessly our poor player. But that's not so much different from the ghosts chasing pac-man in the early '80s

Have you ever created in Unreal a NPC and watch it to stay stuck in place ? Well, it isn't enough to throw NPCs inside the level: we need two new good friend before: a Navmesh, that indicates where to move, and an AI Controller, that gives a brain to NPCs. #unreal #navmesh #AIController

🔧 The final step in Unreal is the export of the game. But that's quite a difficult path to follow. Not only you must fight against the SDK updates, but Unreal want to know in advance the path of each single level as well. And you'll need to write each of them. By hand.

🐭Annoying, isn't it ? When in Unreal the mouse cursor disappears on the UI after the first click. But there's hope still, by the Display Mouse Cursor node. #unreal #UI #mouse #cursor
