BehaviorTree에 대하여

Unreal에 상태에 따른 실시간 변환을 하기위해 좋은 도구이다.

많은 이들이 BehaviorTree로 Ai를 만드는데 사용하며 이로직을 어떻게 사용하는지 알아보도록 하자

add에 이러한 behavior tree를 볼 수 있으며 선택하여 생성해 주도록 한다.

1. Selector

셀랙터의 경우 하나가 실행할때 까지 다음으로 넘어가는 방식을 취한다.

성공을 하면 다음 노드를 실행하지 않으며 이러한 방식으로 status를 적용하여 상태에 따른 로직을 만들 수 있다.

[상위는 첫 wait만 실행이 될것이다]

2. Sequence

실행되면 다음 노드를 실행한다

Sequence는 앞의 노드가 정상적으로 실행 되면 다음 노드도 실행을 한다.

[상위 로직은 3wait가 모두 실행 될 것이다.]

이제 하나의 캐릭터를 만들어 실험해보자

캐릭터 하나를 복사하여 뇌를 심어보자

블랙보드도 생성하여 한쌍으로 뇌를 준비를 한다

블랙보드는 Behavior Tree에 여러가지 변수를 저장하는 곳이다.

이와같이 변수를 저장하고 있고 추가도 해줄 수 있다.

상세한 정보를 보면 base Class라는 Objecy type을 선택해 줄 수 있다.

나는 AttackTarget이라는 것을 만들고 Actor Class로 변환해 보았다.

이제 뇌를 만들었으니 머리를 만들어 주자

블루프린트 클래스를 새로 선택하여

상위의 AIController 클래스를 만들어보자

만들면 뭔가 와이파이 같은모양이 생기며

블루프린트 수정을 들어가

하위와 같이 작성해 준다

이는 AI Controller가 무언가 잡고 실행되었을때 발생하는 함수라 한다.(리스너라고 해야하나?)

Run Behavior Tree로 우리의 뇌를 가동이 되었다.

이제 우리의 뇌의 변수를 가져와 수정해 보자 

상위와 같이 검색하면 매번 이상한게 잡힐 때가 있다 하지만 우리는 이미 뇌가 연결되 있기에 get을 사용하여 블랙보드를 가져오도록 한다.

혹은 이런식으로 보이게 하면 변수가 뜨기도 한다.

이제 블렉보드의 값을 세팅해보자 

이렇게 key Name에 정확한 블랙보드의 변수명을 넣어 주어 원하는 작동이 될 것이다.

이제 우리의 로봇에 머리를 바꿔줘 보자

이제 

이제 움직이는 로직에 새로 넣은 값을 이어주면 뇌와 머리는 완성이다.

맵으로 가보자

Nav Mesh Bounds Volume 이라는 것이 보인다. 이것은 AI 활동 영역이라고 생각하면 된다.

새로 생성하여 큐브모양의 무언가를 크게만들어보자

그리고 P 버튼을 누르면 AI활동 범위를 볼 수 있다.

이렇게 모든 준비는 끝났고 실행해본다.

나를 잘 따라오는 것을 볼 수 있을 것이다

                   SUMMARY OF LESS COMMANDS

      Commands marked with * may be preceded by a number, N.
      Notes in parentheses indicate the behavior if N is given.
      A key preceded by a caret indicates the Ctrl key; thus ^K is ctrl-K.

  h  H                 Display this help.
  q  :q  Q  :Q  ZZ     Exit.
 ---------------------------------------------------------------------------

                           MOVING

  e  ^E  j  ^N  CR  *  Forward  one line   (or N lines).
  y  ^Y  k  ^K  ^P  *  Backward one line   (or N lines).
  f  ^F  ^V  SPACE  *  Forward  one window (or N lines).
  b  ^B  ESC-v      *  Backward one window (or N lines).
  z                 *  Forward  one window (and set window to N).
  w                 *  Backward one window (and set window to N).
  ESC-SPACE         *  Forward  one window, but don't stop at end-of-file.
  d  ^D             *  Forward  one half-window (and set half-window to N).
  u  ^U             *  Backward one half-window (and set half-window to N).
  ESC-)  RightArrow *  Right one half screen width (or N positions).
  ESC-(  LeftArrow  *  Left  one half screen width (or N positions).
  ESC-}  ^RightArrow   Right to last column displayed.
  ESC-{  ^LeftArrow    Left  to first column.
  F                    Forward forever; like "tail -f".
  ESC-F                Like F but stop when search pattern is found.
  r  ^R  ^L            Repaint screen.
  R                    Repaint screen, discarding buffered input.
        ---------------------------------------------------
        Default "window" is the screen height.
        Default "half-window" is half of the screen height.
 ---------------------------------------------------------------------------

                          SEARCHING

  /pattern          *  Search forward for (N-th) matching line.
  ?pattern          *  Search backward for (N-th) matching line.
  n                 *  Repeat previous search (for N-th occurrence).
  N                 *  Repeat previous search in reverse direction.
  ESC-n             *  Repeat previous search, spanning files.
  ESC-N             *  Repeat previous search, reverse dir. & spanning files.
  ESC-u                Undo (toggle) search highlighting.
  ESC-U                Clear search highlighting.
  &pattern          *  Display only matching lines.
        ---------------------------------------------------
        A search pattern may begin with one or more of:
        ^N or !  Search for NON-matching lines.
        ^E or *  Search multiple files (pass thru END OF FILE).
        ^F or @  Start search at FIRST file (for /) or last file (for ?).
        ^K       Highlight matches, but don't move (KEEP position).
        ^R       Don't use REGULAR EXPRESSIONS.
        ^W       WRAP search if no match found.
 ---------------------------------------------------------------------------

                           JUMPING

  g  <  ESC-<       *  Go to first line in file (or line N).
  G  >  ESC->       *  Go to last line in file (or line N).
  p  %              *  Go to beginning of file (or N percent into file).
  t                 *  Go to the (N-th) next tag.
  T                 *  Go to the (N-th) previous tag.
  {  (  [           *  Find close bracket } ) ].
  }  )  ]           *  Find open bracket { ( [.
  ESC-^F <c1> <c2>  *  Find close bracket <c2>.
  ESC-^B <c1> <c2>  *  Find open bracket <c1>.
        ---------------------------------------------------
        Each "find close bracket" command goes forward to the close bracket 
          matching the (N-th) open bracket in the top line.
        Each "find open bracket" command goes backward to the open bracket 
          matching the (N-th) close bracket in the bottom line.

  m<letter>            Mark the current top line with <letter>.
  M<letter>            Mark the current bottom line with <letter>.
  '<letter>            Go to a previously marked position.
  ''                   Go to the previous position.
  ^X^X                 Same as '.
  ESC-M<letter>        Clear a mark.
        ---------------------------------------------------
        A mark is any upper-case or lower-case letter.
        Certain marks are predefined:
             ^  means  beginning of the file
             $  means  end of the file
 ---------------------------------------------------------------------------

                        CHANGING FILES

  :e [file]            Examine a new file.
  ^X^V                 Same as :e.
  :n                *  Examine the (N-th) next file from the command line.
  :p                *  Examine the (N-th) previous file from the command line.
  :x                *  Examine the first (or N-th) file from the command line.
  :d                   Delete the current file from the command line list.
  =  ^G  :f            Print current file name.
 ---------------------------------------------------------------------------
