AI Sense Sight

By default you will only get a update OnPerceptionChange which means From "visible" to "not visible" or vice versa..

To change it to something else like OnEveryPerception (Continuous update whenever target is perceived.) you need to subclass the AI Sense and change the NotifyType in the constructor.

See EAISenseNotifyType NotifyType in UAISense

Warning about not using OnPerceptionChange

if not using that bWantsToNotifyOnlyOnValueChange will be false, making OnTargetPerceptionForgotten delegate never called when age expired.
