I actually think that the real challenge is to make a video of your project and not really show off what you have made so far, because this is a very simple challenge, still I enjoyed it, may do more videos like this in the future, and please forgive me if I sound a bit off but it’s almost 2am o.O!
Hope you enjoy it: FVector::DotProduct Challenge
Edit: I just understood why the AI tank is not moving anymore, it realized that no matter what it does it cannot reach my tank since there is an object blocking the path so it just sits there now.
