Little guide for a bug

[gerrtunk]

I have a strange problem. Im using one of my scripts in one project, it aliases game system and adds a array to it. The script works fine in any other project, but the problem comes with this.

It say that the array is undefined. Knowing that the aliasement is well written i suppose thats a compatibility problem. I have a lot of things out there... and i suppose that for some reason the aliased init isnt called. I tested deeply making a testing p and it still doesnt show up....

My dilema is... i dont know from where to start, thats why im asking if anybody have dealed with something like this. ¿You know what means that? ¿Any ideas?

---------INTRODUCTION----------

 

This script adds a lost feature from old rpgmakers: the changue combate rate 

command. It also lets you restart it.

 

--------INSTRUCTIONS------------

 

modify_step_count(new_step_count, map_id): This lets you changue the basic value

of step counts calculation. You have to pass first the new steps value.

If you dont pass a map id value it will use the map where you are.

 

restart_step_count(map id): This restarts the actual step count, putting it

in a similar initital value. If you dont pass a map id value it will use the

map where you are.

 

-Note that the script tries to save the actual steps of the player and add

that in the new step count. You can anulate that calling the restart method

before modifing it.

 

-The information is saved when you save the game and its permanent. 

 

----------EXAMPLES--------------

 

modify_step_count (56)   --> This changues the steps count of the actual map

to 56.

 

modify_step_count (5, 34)  --> This changues the map 5 to 34 steps count.

        n = $game_system.moded_steps_counts[map]

      # Create the new count adding the actual steps

      @encounter_count = rand(n) + rand(n) + 1 + c

      # Make sure that its at less 0

      @encounter_count.abs

      

  end

  

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

  # * Make Encounter Count

  # moded to check for moded steps rates

  # no es reseteja cuan surts del mapa x ho pot ser x una altre cosa

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

  def make_encounter_count

    

    # Image of two dice rolling

    if $game_map.map_id != 0 

      

      # If exist a modified rate use it 

      if $game_system.moded_steps_counts[$game_map.map_id] != nil

        n = $game_system.moded_steps_counts[$game_map.map_id]

      # If not use bd one

      else

        n = $game_map.encounter_step

      end

      #p 'encounter fet, n', n

      @encounter_count = rand(n) + rand(n) + 1

    end

  end  

  

end

 

Here is the script, anyway. It gives me the error in make_encounter_count, saying that [] is a invalid method for a nil class. Thats why i say that its just not calling that alias.

Note that i already searched for other aliasing of the same name and its ok.

if you're loading an save game, the array won't be initialized, since $game_system is initialized only during the new game.

Also, you should take an look if any other script bellow this one rewrites game_system initialize.

Thanks, i solved the bug. It was a alias that i didnt add the aliased method call at the end.
