AI Senses

AI Sense Sight

About

By default you will only get an 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 the default behavior UAISense::WantsUpdateOnlyOnPerceptionValueChange will be false, making OnTargetPerceptionForgotten delegate never called in UAIPerceptionComponent::ProcessStimuli when age expired. This is setup in the FAIStimulus constructor, see how bWantsToNotifyOnlyOnValueChange is initialized.
