Move_toward_player 8-direction movement

[Twin Matrix]

Does anyone have a version of the def move_toward_player in Game_Character 3 to have 8 directions?

I came up with this:

    if sx == 0 or sx == 1 and sy == 0 or sy == 1
      case rand(2)
      when 0
        rand(2) == 0 ? sx += 1 : sy += 1
      when 1
        rand(2) == 0 ? sx -= 1 : sy -= 1
      end
    end
    if sx == 0 or sx == -1 and sy == 0 or sy == -1
      case rand(2)
      when 0
        rand(2) == 0 ? sx += 1 : sy += 1
      when 1
        rand(2) == 0 ? sx -= 1 : sy -= 1
      end
    end
    if sx < 0 and sy > 0
      move_upper_right
    elsif sx < 0 and sy < 0
      move_lower_right
    elsif sx > 0 and sy > 0
      move_upper_left
    elsif sx > 0 and sy < 0
      move_lower_left
    elsif sx < 0 and sy == 0
      move_right
    elsif sx > 0 and sy == 0
      move_left
    elsif sx == 0 and sy < 0
      move_down
    elsif sx == 0 and sy > 0
      move_up
    end

It's very noob-ish and laggy, plus: the character moves around like a headless chicken. Sure, he follows the hero, but he also randomly walks around in the progress. I hope some expert around here can shed some light on things.

here's what I've made for f0tz!'s pixelmovement:

  def turn_toward_player
    vector = Math.atan2(($game_player.y - @y), ($game_player.x - @x)) * 180 / Math::PI
    case vector
      when -22.49..22.49
        @direction = 6
      when 22.5..67.49
        @direction = 3
      when 67.5..112.49
        @direction = 2
      when 112.5..157.49
        @direction = 1
      when 157.5..180
        @direction = 4
      when -180..-157.5
        @direction = 4
      when -157.49..-112.5
        @direction = 7
      when -112.49..-67.5
        @direction = 8
      when -67.49..-22.5
        @direction = 9
      end
    end

  def move_toward_player
    turn_toward_player
    move_forward
  end

you can easily change it so the event instantly walks toward instead of first facing, and then walking forward. though the effect is the same (unless you want to walk bacwards toward player :p)

What's your version of move_forward?

He's walking like a moron in my version. XD

  def move_forward
    case @direction
    when 1
      move_lower_left
    when 2
      move_down(false)
    when 3
      move_lower_right
    when 4
      move_left(false)
    when 6
      move_right(false)
    when 7
      move_upper_left
    when 8
      move_up(false)
    when 9
      move_upper_right
    end
  end

now that you mention it i remember f0tz! messed up some things with directions of the sprite. what 8 way script are you using?

 

[Twin Matrix]

.. o_O I'm using none, heh. I just want the enemy to move 8 directions, not m'self. ^^ Btw, I tried it out and it's really awkward... The sprite faces right when moving up-left, and the sprite doesn't show all the time. oO

 

[arev]

ahh... you're using 4 way chars, aren't you?
damn... I'm so used to 8 way chars I can't even think of any others :]
ok... try this:

  def move_toward_player
    vector = Math.atan2(($game_player.y - @y), ($game_player.x - @x)) * 180 / Math::PI
    case vector
      when -22.49..22.49
        move_right(false)
      when 22.5..67.49
        move_lower_right
      when 67.5..112.49
        move_down(false)
      when 112.5..157.49
        move_lower_left
      when 157.5..180
        move_left(false)
      when -180..-157.5
        move_left(false)
      when -157.49..-112.5
        move_upper_left
      when -112.49..-67.5
        move_up(false)
      when -67.49..-22.5
        move_upper_right
      end
    end
