Great work on this Legacy

I fixed all the little mistakes in the thread and pinned the topic. So if you need any script support, just come on in

hmm, no requests? None at all...

[The Law G14]

Hey, no requests at all? Any feedback or ideas for this, RRR?

I'm not really sure if this question belongs here but still:

Is it possible to have a script that can activate/deactivate other scripts with in-game commands? [similar to the tons-of-addns thing]

Eventhough I'm overly busy with other stuff, if that's possible, I'd give it a shot and try to make it.
[example of use: have a battler or a sideview battlestyles depending depending on the creature you fight by adding a activation script line before battle processing]

So yeah probably wrong place to ask, but since noone else is asking anything mightaswell use it to bump the topic

[Darkreaper]

If youre answering questions i have 3

Would it be possible to create a script that copies an existing event and places the copy at a location you specify?

Is it possible to create a script that calls up the item menu, lets you select an item and then stores the value of the item to a variable?

And how bout a script that matches X and Y coordinates to a set of variables and then identifies the parent event?
(So you dont need to write a list of if statements a mile long)

[The Law G14]

@Dummy: Hm, that seems like something really difficult to do. I do know of an easy way to deactivate a whole script very easily by putting

CODE

=begin

at the beginning of the script which will comment out everything below it. If that's not what you're looking for, I have an idea on how you could go about doing this.

@Darkreaper: I don't have your first or third questions figured out yet, but for your second question, I have a pretty rough draft of what I think you're looking for:

CODE

#==============================================================================
# ** Scene_Item
#------------------------------------------------------------------------------
#  This class performs item screen processing.
#==============================================================================

class Scene_Item
  #--------------------------------------------------------------------------
  # * Alias Listing
  #--------------------------------------------------------------------------
  alias law_item_variable_update_item update_item
  #--------------------------------------------------------------------------
  # * Frame Update (when item window is active)
  #--------------------------------------------------------------------------
  def update_item
    law_item_variable_update_item
    # If C button was pressed
    if Input.trigger?(Input::C)
      # Get currently selected data on the item window
      $game_variables[1] = @item
      $scene = Scene_Map.new
    end
  end
end

Just open up your item screen, pick an item, and it should be saved in variable 1. You can change what variable it is stored in the 5th to last line of the script.

[Darkreaper]

awesome, where would i install that?

[Night_Runner]

Darkreaper? I remember Charlie Lee & Ty tried answering your question.....
Basically, Sephiroth's script isn't what you're after, it lets you make events, not make copies of them.
Charlie's Auto Populate script hosted here only lets you create copies of events. Unfortunately, I think you need to sign up to RMVXP to see the post, but you won't be able to understand what's going on without Charlie's instructions...
I don't think charlie's script lets you just put the event's clone at a position, but I've got an edited version I can PM you if you want (I got the impression he wouldn't appreciate me posting it here).


2) If you go into the Script Editor, and scroll down to the bottom there should be Main, just right click and insert The Law's script before Main, but Scene_Debug


Oh well, I've made a script for your question 3, read through the instructions a the start, but basically have an event run:

CODE

event_at(7, 8, 9)

and it will look in variable #7 for the x, variable #8 for the y, and return the event at (x, y) in variable #9

[Show/Hide] Night_Runner's Event_At script

CODE

#==============================================================================
# ** Night_Runner's Event_At Script
#------------------------------------------------------------------------------
# Date Created: 5/Dec/09
#      Version: 1.0
# Created for Darkreaper
#  @> http://www.rpgrevolution.com/forums/index.php?showtopic=37119
#
# DESCRIPTION:
#  This script is designed to find the event at a certain x and y coordinates,
#   and return the event's ID number, or 0 if no events are present.
#
# USAGE:
#  Have an event run the script:
#    event_at(3, 4, 5)
#   and this script will look in the game variable 3 for the x coordinate, the
#   game variable 4 for the y coordinate, and will return the event's ID in the
#   game variable 5.
#
#==============================================================================



#==============================================================================
# ** Interpreter
#------------------------------------------------------------------------------
#  Edited to have the event_at command
#==============================================================================


class Interpreter
  #----------------------------------------------------------------------------
  # * Event at (x-coordinate-variable, y-coordinate-variable,
  #              event_id-variable)
  #----------------------------------------------------------------------------
  def event_at(x_var, y_var, ret_var)
    # Get the x & y from the variable
    x = $game_variables[x_var]
    y = $game_variables[y_var]
    # Set the variable to 0 by default
    $game_variables[ret_var] = 0
    # For each event
    for event in $game_map.events.values
      # If the event's x & y match
      if event.x == x and event.y == y
        # Set the variable to the event ID
        $game_variables[ret_var] = event.id
        # Break the for loop
        break
      end
    end
  end
end



#==============================================================================
# END OF SCRIPT

[Darkreaper]

wow thats awesome

[The Law G14]

So you got all your questions answered Darkreaper or are you still having some issues?

[Darkreaper]

@Darkreaper: I don't have your first or third questions figured out yet, but for your second question, I have a pretty rough draft of what I think you're looking for:

CODE

#==============================================================================
# ** Scene_Item
#------------------------------------------------------------------------------
#  This class performs item screen processing.
#==============================================================================

class Scene_Item
  #--------------------------------------------------------------------------
  # * Alias Listing
  #--------------------------------------------------------------------------
  alias law_item_variable_update_item update_item
  #--------------------------------------------------------------------------
  # * Frame Update (when item window is active)
  #--------------------------------------------------------------------------
  def update_item
    law_item_variable_update_item
    # If C button was pressed
    if Input.trigger?(Input::C)
      # Get currently selected data on the item window
      $game_variables[1] = @item
      $scene = Scene_Map.new
    end
  end
end

Just open up your item screen, pick an item, and it should be saved in variable 1. You can change what variable it is stored in the 5th to last line of the script.

So i think it kinda works, but not how i need it.
What im using it for is for cooking:
Say you have an apple and a fish, you make a fire and want to cook some food. So you "use" the fire and it pulls up your inventory screen and lets you choose what you want to cook. You pick the fish, it removes the fish item and after a little bit gives you a "Cooked Fish" item

[The Law G14]

Sorry for the late response, but does this item screen only inlcdue items that can be cooked or just any item in your inventory inlcuding weapons and armor?

[Darkreaper]

well id prefer it if it was only "cookable" items, but i dont know if thats possible or worth the trouble

[The Law G14]

Yeah, that's possible so I'll try to get this script in to you in the next couple of days

[Darkreaper]

Sweet, thatd be of great help

[The Law G14]

This is a rough draft of what I have so far. Just make an event and go to the third page of the list of event commands and click Script. Type in this code:

CODE

$scene = Scene_Cooking.new

To change what variable the item is stored in, go to line 81 of the script.

Hope I was at least kind of close lol:

@Dummy:
Assuming you mean whether it's possible to activate/deactive scripts dynamically in-game then I am afraid it's in the general case impossible. I believe that problem is undecidable. If it is, then it is impossible to write an algorithm which solves the problem in the general case.
In that case I would suggest dealing with it application specific. I.e. customizing the scripts so they can be turned on and off dynamically.

If you are talking about statically say not evaluating certain sections, then that is very much possible.

*hugs*

[The Law G14]

@Darkreaper: Did you put weapons or armor in there? I only made it so that it included items only but I can add weapons and armor if you want. Also, do you have any other custom scripts?
