Hey,
quick question, how do you control the behavior of the AI Actor? Do you use Behavior Trees or are you using the Actor or AI Controller Blueprint to control its behavior?
Also what do you use to detect the other character? The perception system of Unreal or did you create your own system?
Depending on that how you can achive this varies.
Also what part from what you want to achieve do you have problems with? Just the timing part or more?
