Damaging Tiles and Prevention Spell Options

[RedMoney]

So, I have been searching everywhere with no luck to find a poison marsh type script. What I want is a script that deals damage to all the characters in the party when they step on a specific tile. I also want to be able to easily edit the script to make stronger and weaker tiles (poison marsh, electric floor, lava, etc...).

I tried to make a script like this

if tile_id = 195
for actor in members @hp - 1
end

Which caused the game to crash.

Also, I want to be able to make a spell that prevents the tiles from causing damage.

My thoughts right now - I think that if the tile causes a state that deals slip damage and that state ends after one step, it will be easy to make a spell tat stops that state from being entered.

Thank you in advance for anyone who is willing to help.

I think that this should work, but I'm not sure how tile id's work in VX.

If it doesn't work, let me know, and I'll try and learn how the ID's work

[RedMoney]

The following error happened :

uninitialized constant NR_PoisonTiles::Counter_Spell_ID

note, I got the tile ID number wrong so I changed it to 0, then changed the tile in the game accordingly.

Oops, I forgot to change the spell to skill.

still same error. Also, it broke the game, I can now walk through any tile. I removed the script and the bug still did not go away.

should be noted, I can only pass through floor tiles, not Tile B types.

*Edit*
I don't think that the tile_id's work in the same way you think it does. I've been looking through the code, and only the events tile_id will ever get set to a non-zero value, and that's based off the character graphic you give them.
I've redone the script, it has two parts now, this first script is supposed to be removed when you're finished setting up, and it simply shows a window that displays the tile ID's that the player is standing on

CODE

#==============================================================================
# ** Window_TileID
#------------------------------------------------------------------------------
#  This window displays tile ID underneath the player
#==============================================================================

class Window_TileID < Window_Base
  #--------------------------------------------------------------------------
  # * Object Initialization
  #     x : window X coordinate
  #     y : window Y coordinate
  #--------------------------------------------------------------------------
  def initialize(x = 0, y = 0)
    super(x, y, 160, 3 * WLH + 32)
    self.back_opacity = 200
    @counter = 0
    refresh
  end
  #--------------------------------------------------------------------------
  # * Refresh
  #--------------------------------------------------------------------------
  def refresh
    self.contents.clear
    data = $game_map.data
    px = $game_player.x
    py = $game_player.y
    width = self.contents.width
    for i in 0..2
      text = "Layer %d: %d" % [i, data[px, py, i]]
      self.contents.draw_text(0, i * WLH, width, WLH, text)
    end
  end
  #--------------------------------------------------------------------------
  # * Frame Update
  #--------------------------------------------------------------------------
  def update
    @counter += 1
    if @counter > 5
      refresh
      @counter = 0
    end
  end
end



#==============================================================================
# ** Scene_Menu
#------------------------------------------------------------------------------
#  Edited to show the Window_TileID
#==============================================================================

class Scene_Map
  #--------------------------------------------------------------------------
  # * Alias Methods
  #--------------------------------------------------------------------------
  alias nr_windowTileID_main    main    unless $@
  alias nr_windowTileID_update  update  unless $@
  #--------------------------------------------------------------------------
  # * Main Processing
  #--------------------------------------------------------------------------
  def main(*args)
    @id_window = Window_TileID.new
    # Run the original main
    nr_windowTileID_main(*args)
    @id_window.dispose
  end
  #--------------------------------------------------------------------------
  # * Frame Update
  #--------------------------------------------------------------------------
  def update(*args)
    @id_window.update
    return nr_windowTileID_update(*args)
  end
end

And this second script is just like the previous poisons script, but you use the tile id shown from the previous script when you're standing on the poisoned tile, and it poisons the player when they're standing on it

Nice, check out the big brain on night runner! It works properly, i set it to tile id 1591 and the purple floor dealt the damage.

Thank you very much for the script.

[The Buffoon Plat...]

You can definitely do this with events; I did it in XP a while back. I just can't remember how exactly it was done.

You can definitely do this with events; I did it in XP a while back. I just can't remember how exactly it was done.

Make the event below characters as priority.

Set it to damage the player (change HP), have it flash/tint the screen if you want the player to be aware of the damage (put a sound effect too if you want to tell them through sound what's going on).

Tada, pretty simple stuff!
