Script problems... again...

Sorry for the indescriptive title, but I don't think if I'd written 'Beacon Script problems', you wouldn't been informed better ^_^

Anyway, I tried to make a Beacon script... and as it's the first time somebody attempts this (AFAIK), I'll explain it's purpose shortly:
Events on the map marked with a 'Beacon' comment have an opacity of 0 until the player comes near them. Depending on how close the main character gets, the opacity raises and becomes 255 if the player is above the object. If he gets further away, the opacity decreases again. Of course, this should work with multiple objects on a map simultaneously.

Well, that's the theory... my tries to get this thing to work ended like this:

PHP: 
class Beacon
  #--------------------------------------------------------------------------
  attr_accessor :character
  #--------------------------------------------------------------------------
  def initialize(character=nil)
    @character = character
  end
  #--------------------------------------------------------------------------
  def main
    # checks for the comments inside the event
    if (character.is_a?(Game_Event) and character.list!=nil and
      character.list[0].code == 108 and 
      character.list[0].parameters == ["Beacon"])
      # checks for distance between player and event
      d=Math.sqrt(dx.abs**2+dy.abs**2)
      # changes the event's opacity relative to the distance
      character.opacity = [255-d*80,0].max
    end
  end
  #--------------------------------------------------------------------------
end

This is the first version which doesn't brings up any errors, but the events simply don't care about the script ^_^. I commented the 'action' lines for you guys so you can see what I was trying to do, but I have no clue how to go on from here... help would be very apprechiated... :D

Thanks in advance

Well, to be honest, I have no idea what it does... I've seen it several times like that in no-window classes, so I think it's just a initialization constant. In fact, I've copied the whole definition out of Retaime's reflection script ^_^ (I guess that's what the error is... 'character' is simply not defined... but Retaime didn't define it, too... O_o )

"super" finds the method of the same name in the parent class. For example:

Code: 
class Parent_Class
  def initialize(argument)
    p 'Parent_Class Initialize'
  end
end

class Child_Class < Parent_Class
  def initialize
  p 'Child_Class Initialize'
    super(argument) # Call's Parent_Class's initialize method
  end
end

Child_Class.new

This would call both initialize methods.

And are you adding the "Beacon" characters in the setup method of Game_Map?

Ah, good thing to know... *deletes 'super'* ^_^

And I haven't done anything outside this script, everything I did besides the comment inside the event is in the first post.
Counter-question: Do I have to add anything in Scene_Map? :D

First you would need to create an instance of that class for each event that add that coment.
For that you would need an hash like
Code: 
$beacon[id] = {}
id being the event id that add that comment on it.
You would need also a way to get the event id to that script.
In scene_map you would need to update that script
with:
Code: 
for i in 0...999
next if $beacon[i] == nil
$beacon[i].main

If you neeed further help add me on msn chaosg1@hotmail.com

Edit: If you want a step by step tutorial I might do it, but it will take a while...

Sorry, I don't have MSN... but shouldn't it be Chaosg1? ^_^

And I do need further help, as I have no idea on where to place these script pieces... well, besides the last one what'd give me nothing without the previous stuff :P
Fir the event ID, I've seen scripts that worked with a comment in the event alone, not needing any event ID input...

Just for trivial information: It's BlueScope, not Blue Scope. It isn't supposed to be Blue Scope. Just BlueScope. Thanks :D

For the script, it isn't working for me... did you tested it? Or do I have to put anything inside the event's comment besides the string 'beacon'? ^_^

PS: I guess I overestimated RGSS... so much lines for an actually very simple process...

It isn't working?? It was working for me...

Btw The string must be "Beacon" or it won't work...
Probably there is/are other ways of doing this but, This was the fastest way I could remeber lol

I did put 'Beacon', I know that RGSS is case-sensitive since yesterday XD Well, I met MeisMe in chat just now, and he said the problem is that $beacon has never been initialized... he also said that it's easier to get everything into Game_Event rather than in several classes... and he said that he's going to do it now ^_^ But I guess he gave up meanwhile XD

Okay, it works in your demo, but neither in my game nor in a new project as I tried before... but I found an error which might be the key to everything... delete the comment out of the beacon event with ID 001 and you'll notice...

EDIT: It doesn't work for me putting the first event to Beacon, too... there is also a little error in your version: The Beacons appear shortly while the map still is fading in... I'd be glad if you could fix that.

It works... though I wonder how you did it ^_^

There's still one problem... Look at the events directly after you enter the map. They appear for a short time (until update definition is triggered) and then disappear, but sadly, that's too late ^_^

EDIT: Thanks for the 'BlueScope', I really apprechiate it :D

I just changed a line, I will see what I can do About the ghost events lol:
You are welcome...

I changed this line:
for g in 1...$beacon.size
$beacon[g].update if $beacon[g] != nil

to
for g in 1...999
$beacon[g].update if $beacon[g] != nil

It gives a little bit of lag but It was the best way I could find...

Couldn't you use Near's View Range script.

for event in $game_map.events.values
if in_range?($game_player, event, 4)
event.opacity = 250
else
event.opacity = 0
end
end

you can get the in_range? method from Near's ABS

no it doesn't make sense.. I don't think you understand how it works.

Here is the whole script;
Code: 
module Beacon
  #--------------------------------------------------------------------------
  # * Fram Update- Called from Scene_Map Update
  #--------------------------------------------------------------------------
  def self.update
    #Get all the events on map
    for event in $game_map.events.values
      #If the event is in range
      if in_range?($game_player, event, 4)
        #Make the opacity 250
        event.opacity = 250
      else #If not in range
        #Make the opacity 0
        event.opacity = 0
      end
    end
  end
  #--------------------------------------------------------------------------
  # * Checks if an object is in range.
  #--------------------------------------------------------------------------
  def self.in_range?(element, object, range)
    x = (element.x - object.x) * (element.x - object.x)
    y = (element.y - object.y) * (element.y - object.y)
    r = x + y
    if r <= (range * range)
      return true
    else
      return false
    end
  end
end

class Game_Character
  attr_accessor :opacity
end
