EBD is a BTs tool which is based on the design of Opsive's Behavior Designer and extend it's functions for Unity developers.
With EBD, AI developers can do sth. that can't be done in BD:
1、Extend the BTs like adding or removing tasks in runtime.
2、Serialize the BTs Asset staticly or dynamicly and translate the serialization info.
There must be bugs in EBD, and it is still incomplete. Bear with me.
