  • Using Task.current.Succeed(), Task.current.Fail() and Task.current.isStarting in task methods.
  • WHILE and IF nodes now succeed when their condition fails.
  • Allowed defining task as static method.
  • Behaviour node is now named tree.

  • Syntax changes: parenthesis and coma are now optionals for node parameters.

  • Fixed parsing comments.
  • Fixed null pointer error occuring when no BT script is assigned to a panda Behaviour.
  • Fixed Panda Behaviour not being initialized when disable on game start.
