[GT]How to make WORKING artificial intelligence of a wandering minotaur?
Hello everybody I want to make an adversary who wanders through the maze (he should also theoretically move exactly in the middle of the walls between him), and when he comes across a player, he starts chasing after him, but this has not yet been realized. I wrote this script a lot of time, and it did not give me anything - AI constantly turns into a wall. Can you help me with ideas on how to make such a wandering AI without using NavMeshAgent and invisible points scattered on the map, to the coordinates of which the AI will go. P.S. For those who still decided to recreate the situation - the distance between the walls is 25, the passage width is also 25, the whole map is 250 by 250, the height of the walls is 10 and the AI has a size of 5-5-5.

make sure your rays are not hitting your $$anonymous$$otaur, cause then they will always be true.. not sure what is wrong with invisible points.. You could generate them on the fly and use them as targets for your Ai.. Or you can use flowfeild vectors, I have an asset for that.
