For a school project i just started using unreal engine, i am creating a very basic shooter game with very simple AI, i did the ai from a blueprint help video and it worked fine (it was supposed to follow the player) I think i pressed something with my unreal engine because now when i start the game, the camera doesnt lock into the first person character it was supposed to lock into until i press possess on the top right, also my ai is just standing stationary even though i did not change a single thing in their or my characters blueprint.
If you think you changed some editor settings, delete your Config folder in your project directory and open the project again. When you have character or pawn to posses, check if you are possesing with Player 0. This setting stands on character or pawn blueprint’s Class Defaults panel.
