As we discussed earlier, a character AI system needs to be aware of its surrounding environment: for example, NPCs need to know where the obstacles are, where the player is looking, if they are in the player's sight, and a lot more. The quality of the artificial intelligence of our NPCs depends, for the most part, on the information they can get from the environment. Based on that information, the AI-powered characters can decide on which action to execute. If there's not enough information, characters might show unusual behaviors, such as choosing the wrong places to take cover, idling, or looping in strange actions without knowing how to proceed. A quick search for AI glitches on YouTube opens the door to a huge collection of funny behaviors of AIs that are common, even in AAA games.
Theoretically, it is possible give to the NPCs all of the information...
