Diagonal Movement only

[dagarath]

My first request for an actual script, TBH I can prolly figure out how to do this, but I have so much already to do just with ripping images that I need >_<

I want to replace Up, down, left, right with diagonal movement. The game I am making only uses diagonal movement so itd be like this

LEFT = Northwest
UP = Northeast
DOWN = Southwest
RIGHT = Southeast

I'll just tread this as a Script Support topic because of the simplicity :p

Check Game_Player for the specific movement commands (i.e. move_down, move_upleft, ...) - if your entire game is supposed to use diagonal movement instead of regular UDLR, you're best off replacing the single-direction move commands with the multidirectional ones directly, as that might give you the one or other compatibility improvement... nevermind shorter method names.
If you want it nice and shiney, you need to go to... Scene_Map.update, if I'm not mistaken, and exchange the command names there. Might be possible that they're directly within Game_Player, though... you need to check.

Also, for future topics, please add which maker you're using. We got those fancy badges for topic titles for a reason...

OH shoot, sorry lol RMXP hehe, thanks I had no idea this was so simple

I basically did this, and I get diagonal movement but now my touch events arent working lol

 

    alias isometric_update update

  def update

      unless moving? or $game_system.map_interpreter.running? or

             @move_route_forcing or $game_temp.message_window_showing

        case Input.dir8

        when 1..2

          move_lower_left

        when 3

          move_lower_right

        when 4

          move_upper_left

        when 7

          move_upper_left

        when 6

          move_lower_right

        when 8..9

          move_upper_right

        end

      end

      unless moving?

        if Input.trigger?(Input::C)

          check_event_trigger_here([0])

          check_event_trigger_there([0,1,2])

        end

      end

    else

      isometric_update

    end

 

Alright so this works fine, BUT..it moves 1:1 X:Y, I need it to be 2:1 for correct movement, I know I will have to replace this bit in the movement commands

 

def move_lower_left

...

      @x -= 1

      @y += 1

...

end

 

with say this? and then halve my movement speed?

 

def move_lower_left

...

      @x -= 2

      @y += 1

...

end

 

Here is an example of one of the maps I am using

UPDATE: answered my own questions with this, tho i will probably alias it

 

class Game_Character

    end

    # When a down to left or a left to down course is passable

    if (passable?(@x, @y, 2) and passable?(@x, @y + 1, 4)) or

       (passable?(@x, @y, 4) and passable?(@x - 1, @y, 2))

      # Update coordinates

      @direction = (@direction == 6 ? 4 : @direction == 2 ? 8 : @direction)

    end

    # When an up to left or a left to up course is passable

    if (passable?(@x, @y, 8) and passable?(@x, @y - 1, 4)) or

       (passable?(@x, @y, 4) and passable?(@x - 1, @y, 8))

      # Update coordinates

      @y -= 1

      # Increase steps

      increase_steps

    end

  end

  #--------------------------------------------------------------------------

  # * Move Upper Right

  #--------------------------------------------------------------------------

  def move_upper_right

    # If no direction fix

    unless @direction_fix

      # Face right if facing left, and face up if facing down

      @direction = (@direction == 4 ? 6 : @direction == 2 ? 8 : @direction)

    end

    # When an up to right or a right to up course is passable

    if (passable?(@x, @y, 8) and passable?(@x, @y - 1, 6)) or

       (passable?(@x, @y, 6) and passable?(@x + 1, @y, 8))

      # Update coordinates

      @x += 2

      @y -= 1

      # Increase steps

      increase_steps

    end

  end

end

 

now it just struck me I have to modify event handling and collision (since I can diagonally sneak through stuff now getting stuck, and events on touch no longer trigger)
