My First Script - Jump on Command

[fadingaura]

This is my first script... I know its probably been done before but here it is...

Insert this into Game_Player

if Input.trigger?(Input::ALT)
     keyjump
end

Directly after this

unless moving? or $game_system.map_interpreter.running? or
       @move_route_forcing or $game_temp.message_window_showing
  # Move player in the direction the directional button is being pressed
  case Input.dir4
  when 2
    move_down
  when 4
    move_left
  when 6
    move_right
  when 8
    move_up
  end

Next insert this

#--------------------------------------------------------------------------
  # * Jump
  #--------------------------------------------------------------------------
  def keyjump
      # If passable
      case @direction
      when 2
        if jumpable?(@x, @y, @direction)
          @y += 2
          jump(0, 0)
        end
      when 4
        if jumpable?(@x, @y, @direction)
          @x -= 2
          jump(0, 0)
        end
      when 6
        if jumpable?(@x, @y, @direction)
          @x += 2
          jump(0, 0)
        end
      when 8
        if jumpable?(@x, @y, @direction)
          @y -= 2
          jump(0, 0)
        end
      end
    end

and this

#--------------------------------------------------------------------------
  # * Determine if Jump Passable
  #     x : x-coordinate
  #     y : y-coordinate
  #     d : direction (0,2,4,6,8)
  #         * 0 = Determines if all directions are impassable (for jumping)
  #--------------------------------------------------------------------------
  def jumpable?(x, y, d)
    # Get new coordinates
    new_x = x + (d == 6 ? 2 : d == 4 ? -2 : 0)
    new_y = y + (d == 2 ? 2 : d == 8 ? -2 : 0)
    # If coordinates are outside of map
    unless $game_map.valid?(new_x, new_y)
      # impassable
      return false
    end
    # If through is ON
    if @through
      # passable
      return true
    end
    # If unable to leave first move tile in designated direction
    unless $game_map.passable?(x, y, d, self)
      # impassable
      return false
    end
    # If unable to enter move tile in designated direction
    unless $game_map.passable?(new_x, new_y, 10 - d)
      # impassable
      return false
    end
    # Loop all events
    for event in $game_map.events.values
      # If event coordinates are consistent with move destination
      if event.x == new_x and event.y == new_y
        # If through is OFF
        unless event.through
          # If self is event
          if self != $game_player
            # impassable
            return false
          end
          # With self as the player and partner graphic as character
          if event.character_name != ""
            # impassable
            return false
          end
        end
      end
    end
    # If player coordinates are consistent with move destination
    if $game_player.x == new_x and $game_player.y == new_y
      # If through is OFF
      unless $game_player.through
        # If your own graphic is the character
        if @character_name != ""
          # impassable
          return false
        end
      end
    end
    # passable
    return true
  end

under Move_Up in Game_Character3
Then Enjoy!
Please report any bugs!

After Landing

 

[RMXPirate]

This is pretty cool kind of i guess

 

[Anonymous]

Mmm... Terribly sorry, but this is easily done with common events. What would make this worth it, though, is if you made cretain tiles unjumpable, or if you can't jump two tiles, jump one tile. Sorry if I seem offensive, I really just want to help, and I hope I did. And, I mean, it's great for your first script - mine was one that outlines text :P

 

[Jeff 8- )]

I agree with you there smartguy. But a good idea to make it seem more better in my opinion, would be to like hmmmmm how should I say this. OK probably in certain areas having to jump is te only option. Or you could try to make it like the reaction commands in KH2. Hope that gives you a better idea for your next script = ).

 

[Chronic]

I guess it's useful to somebody,,

 

[trebor678]

Hey, is there any chance that you could make it into one whole script, I tryed myself but was unable to do as im only a rookie! Thanks :D

 

[Twilight]

Although its necro posting, You can use Sephiroths Advance Movement Script

The above jump command in one cut and paste above main script, for anyone who still wants it:

Hey, could you add a couple of features:

1. Not able to jump over an event that has a comment saying "\NotJump" eg
2. Not able to jump over a tile that has a tile id of 1
3. Ive there is 1 tile in front of you, you can jump one tile rather than not jumping at all!

Thanks :D

[squall]

fadingaura thank you so much for the script

and

thanks to vash you are the best vash^^

 

[Tensa]

Oops- double post (second one was better.)

 

[Tensa]

I remember that before my compute crashed (and you guys apparently lost your old domain,) there was an advanced jumping script let you set the jump length and would automatically adjust that distance if the tile you would have landed on was impassable.
It also had the 'nojump' thing trebor just mentioned and some fancy conditions to decide if the player had the jump ability or not (the only one I remember was that you could have them equip an item to enable it.)

It would be really nice to have that again ;_;

[trebor678]

His jump script doesnt have all the features that i want, but this one does, but there is a bug in it, no matter what the tile id, you can still jump over it, hope someone can fix it...

Thanks :D

 

[theabsoluteone]

Ill look into it, BTW I forgot my pword as fadingaura and this is my new account! Sry bout no post in a while!

 

[Tensa]

Trebor: Wow, I do believe that's it- though I don't remember there being that bug...

 

[trebor678]

I know, but does anyone know how to fix it!? I've had a look, but im not the best scripter!

Thanks :D

 

[Tensa]

Well, I think it's more of a bad explanation of what it's supposed to do. As it stands you can jump anywhere that has appropriate passability and over impassible spots if the length is right which is pretty much what it ought to do.
Ptting a bunch of /tall commented events where you don't want them jumping doesn't seem like too big of a hassle.

 

[mikethecool]

Alright, the only problem i found with this is that, if you hold down your jump key, you can walk over anything.
Kind of a big problem >_>
