Setup

3 Step Setup:

Add Master Component to your AI Controller.
Add Slave Component to your Player Controller.
Go to Settings->Collision and add a Trace Channel:

Name: SightPerp

Default Collision: ignore

Once you've added your master component to the AI Controller. You can use the events and functions from within your AI Controller.

Master Component (Inside your AI Controller)

Component Settings:

Sight Distance (cm) - How far the AI can see. You do not need to set this low for dark environments, the Blueprint will handle it. --DEFAULT IS 50m--
- - - - Remember that distance effects the detection amount.
        eg, Set to 5000 (50m) - So at 50m the detection amount will be 0%.
Peripheral vision Angle - AI's Peripheral vision Angle

Time To Forget (seconds) - How long before the AI forgets about the player. An example would be when the AI is searching for the player. --DEFAULT IS 0-- Note: 0 turns off the Forget feature.
Use Light Test - Will do light tests for Shadows, Darkness and our Light Blueprint --DEFAULT IS TRUE--
Minimum Detection Percentage (2-99) - The AI will never detect a Player under this percentage. --DEFAULT IS 45--

Events

The On perception Updated Event will give the AI Controller an array of structures with the currently perceived actors, their detection percentage and their Last known Position.

The On Forgotten Actor Event will trigger every time the AI forgets an Actor based on the time in the 'Time to forget' setting.

Functions

Get Currently Perceived Actors is a function version of the On Perception Updated Event.

Get All Perceived Actor gets All Perceived actors even if they have been forgotten.

Get Known actors gets all Actors that have not been forgotten.
