Evidence Locker
Version: 1.1
Author: modern algebra
Date: November 11, 2010
Version History
Version: 1.1
Author: modern algebra
Date: November 11, 2010
Version History
- <Version 1.1> 11.11.2011 - Added the possibility of multiple different evidence lockers (so the function can be used for different purposes) as well as made it easier to call the scene with a simple call_evidence method. Added a demo.
- <Version 1.0> 08.02.2008 - Original Release
Description
This script allows the player to choose an evidence item from his or her inventory and set conditions depending on which item is chosen. This allows for an interactive exchange, particularly in games where the presentation of evidence is necessary, such as detective games or minigames. In addition, you can have multiple different evidence lockers, allowing for different functions. Maybe some items you'll want to use this script to create a trading features, while others you'd like to use for detective purposes. This is now possible. As well, the same item can belong to multiple different evidence lockers.
Features
- Simple way to identify items as evidence
- The scene is a subclass of Scene_Item and so should fit in with any custom Scene_Item that does not depart too heavily from the basic
- Allows your events to react to the evidence chosen
- Perfect for games where the presentation of evidence or proof is necessary or useful
Screenshots
Should look exactly the same as your Scene_Item
Instructions
Place this script into its own slot in the Script Editor (F11), somewhere above Main and below Materials.
See the instructions in the header of the script for more instruction on how to use the script in your game.

# Evidence Locker
# Version 1.1
# Author: modern algebra (rmrk.net)
# Date: November 11, 2010
#~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
# Description:
#
# This script allows the player to choose an evidence item from his or her
# inventory and set conditions depending on which item is chosen. It also
# allows you to have multiple evidence lockers, in case you only want to
# choose from a limited subsection of items in your possession in one case and
# a different subsection in another case.
#~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
# Instructions:
#
# To set an item so that it will show up in an evidence locker, you need
# only type the following into the note box of an item
# \evidence[locker_id]
# locker_id : the ID of the locker you want this item to be in. If
# excluded entirely (ie. just \evidence ) then it's in locker 0.
#
# To call the Evidence scene, use this code:
#
# call_evidence (locker_id)
# locker_id : the ID of the locker you want to open. If excluded, (ie.
# just call_evidence ) then it opens locker 0.
#
# To access the item the player has chosen in the scene, you have four codes:
#
# $game_temp.evidence_name the name of the item chosen
# $game_temp.evidence_amount the amount of item in the party's possession
# $game_temp.evidence_type 0 => Item, 1 => Weapon, 2 => Armor
# $game_temp.evidence_id the ID of the item chosen
#
# You can use any of these in a conditional branch by utilizing the script
# condition and typing in this:
#
# $game_temp.evidence_name == 'name'
# $game_temp.evidence_amount == positive integer
# $game_temp.evidence_type == integer between 0 and 2, inclusive
# $game_temp.evidence_id == positive integer
#
# If necessary, type and id will only return true for the exact item wanted.
# In general, name will be sufficient and probably easier, though confusion
# may arise if you have more than one piece of evidence with the same name.
# The amount is in case you want a number restriction on the evidence, so if
# you need two instead of just one or something. You can join conditions with
# &&, so this would be legitimate:
#
# $game_temp.evidence_type == 2 && $game_temp.evidence_id == 24

How can I subtract the item after the player presents it to the person?
Other than using the conditional branch that checks if he presents it, and then using the event command to subtract the said item. But in my game, there are a lot items and I don't want to use like many conditional branches. That would get messy. Also, in some cases I'm using the 'or' feature. Like $game_temp.evidence_id == 1 || $game_temp.evidence_id == 2. How can I subtract that since I don't know which one the player will present the item #1 or item #2?
So I'm here, wondering if it's possible to do something like this in easier way?
Other than that, this script is really useful. Nice work.

Code: [Select]
$game_temp.evidence_id = @item.id
$game_temp.evidence_name = @item.name
$game_temp.evidence_amount = $game_party.item_number (@item)Place this:
Code: [Select]
$game_party.lose_item (@item, 1)So that section of the script would look like:
Code: [Select]
else
# Set evidence variables to the item chosen
$game_temp.evidence_type = @item.is_a? (RPG::Item) ? 0 : @item.is_a? (RPG::Weapon) ? 1 : 2
$game_temp.evidence_id = @item.id
$game_temp.evidence_name = @item.name
$game_temp.evidence_amount = $game_party.item_number (@item)
$game_party.lose_item (@item, 1)
return_scene
endBut it will only and always remove 1 instance of that item. I personally think the method you've suggested would work better.

If you're in mood for scripting, maybe you can create a skill add-on or update for Evidence Locker? So I would have both items and skills evidence locker? (Note: I don't mean having both items and skills in one window. It would be nice to be able to summon the item window when I call for it, and later summon the skill window when I call for it)
If you're looking for specifics, I want the player to be able to 'present' his skills. Now I'm not sure how it all works out for the multiple members in party... Pressing a specific key to go through different members' skill-list, or using the script call to get a specific member's skill-list?
I'm only really interested into the presented skill's ID but if you want, you can make additional features like skill's name, etc, for others.
Your Evidence Locker is incredibly amazing. I've been working with it for months and loving it so far. I admit that I'm not using your Evidence Locker to present the evidences. Instead I have been using it for the gift system, and other things relating to the presented items.
I want to be able to 'present' a skill to the guy so he can upgrade it (via my event system)

To me, the instructions are a little unclear because I don't know what goes where and ?_? I also don't really get what happens when all the conditions are met and stuff.. XP I'm just dumb? Idk.

before going on with the rest of the event?
(sorry for the necropost)
Post by: modern algebra on May 07, 2011, 10:24:51 PM
Code: [Select]
$game_temp.evidence_amount >= 2
or just:
Code: [Select]
$game_temp.evidence_amount > 1

But I need to know if there's any chance of you making this compatible with the Simple Sort Inventory script that cozziekuns made?
I really need it for my project.
