Unreal Engine 5 - AI Last Seen Location improvements and Bug Fixes - Action RPG #77

Here we are going to work on improvements for the AI last seen location mechanism we have implemented. As of now, the silhouette that represent the last seen location by AI enemies tend to appear and change quickly during the gameplay. Here we are going to make it appear only after some time when all the enemies have lost the sight of the player character and even if one of the enemies detect the player, the silhouette will promptly disappear.

Unreal Engine 5 - AI Alert Other AI Characters - Action RPG #76

Here we are going to work on how AI characters communicate to other AI NPC characters when they detect an opponent.
