Behavior Tree & Blackboard
I mainly learned from this page https://dev.epicgames.com/documentation/en-us/unreal-engine/behavior-tree-in-unreal-engine---quick-start-guide
1. In Unreal 5.2 The Blackboard come with a key by default called selfActor, which can take care of adding the EnemyActor Step (To DO: Add picture)
2.Selector Executes branches from left-to-right and is typically used to select between subtrees. It will stay on a Selector until its successful, than move on to the next. Nothing fails here? 3. A Sequence Composites , executes until something fails, such as it we are chasing the player than succeed, than we can move on to attack if we fail to catch player we don't attack.
