The Run Behavior Task enables you to run another Behavior Tree by pushing sub-trees onto the execution stack. One limitation to consider however is that the subtree asset cannot be changed during runtime. This limitation is caused by support for the subtree's Root level Decorators, which are injected into the Parent tree.
The Move Directly Toward Task node moves the AI Pawn toward the specified Actor or Location (Vector) Blackboard entry in a straight line, without regard to any navigation system. If you need the AI to navigate, use the Move To Task node instead.
The Finish With Result Task node can be used to instantly finish with a given result. This node can be used to force a branch to exit or continue based on the defined result.
A behavior tree is a system used to determine which behavior an AI should perform. For example, you could have a fight and a run behavior. You could create the behavior tree so that the AI will fight if it is above 50% health. If it is below 50%, it will run away. In this tutorial, you will learn how to:
Brain: The brain is how the AI makes decisions. You can create this in different ways such as C++ code, Blueprints or behavior trees. Since you already have the body, all you need is a soul and brain. First, you will create a controller which will be the soul.
A blackboard is an asset whose sole function is to hold variables (known as keys ). You can think of it as the AI’s memory. While you are not required to use them, blackboards offer a convenient way to read and store data. It is convenient because many of the nodes in behavior trees only accept blackboard keys.
