This script allows the player to combine up to four items in a simple to use script that will allow them to create items.

• Item filter, will only show certain items that are in the players inventory that are allowed to be combined.
• Recipes are easy to create by using a simple array system.
• Creation filter, this will allow you to control what the player can make, this way the player can only make what they know how to make.
• Version 1.5 - Combine any Item, Weapon, Armor together to make anything.
• Version 1.6 - Can give the player a useless item if the combination is wrong.
• Version 2.0 - Can show a window that contains known recipes.
• Version 2.3 - can have items that are not consumed when combined.

Paste in the scripts database above main and then follow the instructions in the script header.

If you find any errors or would like to suggest an idea for a future version post them in here.


None that I know of.


Don't post this on any other forums without my permission, and you are free to edit the script in anyway but you must still give me credit some where.

I can definately see how this could be useful.

Kudos to you, Mr. Wiggles.

I like the design of this - very unique for creation scripts.

Thanks guys. :D

I wish my real-life alchemy level was high enough to make something out of arrows, machine gun ammo and shotgun shells besides just an arrow with some metal and plastic taped to the end.

rofl..

I can't get the script to work. I copied the script above main, then I called $scene = Alchemy.new through an event on map (with the default constants) and when I try to activate it, it says: Script 'Craft_Script' line 122: NoMethodError occurred. undefined method `description' for nil:NilClass
Then I have changed the constants like this:

13 ALCHEMY_ITEMS = [1,2,3]
16 COMBINE_DUPS = false
19 CHECK_RECIPE_BUTTON = Input::A
31 ALCHEMY_RECIPES = [
32 [1,2,0,0,3]
33 ]
45 BLUE_PRINTS =

• 
  48 PENALIZE = true
  
  Then... the same error... after that I tried to add a blueprint through call script feature: $game_system.add_blue_prints(0) and when I try to take the blueprint: Script 'Craft_Script' line 250: NoMethodError occurred. undefined method `include' for
• :Array
  
  I'm pretty new to RMXP so you'l have to excuse me if I talk gibberish or/and don't understand a word...

its fine, i know what it is that is going wrong i was gonna update this script, but the forum crashed. When i get on my computer i will upload the new version.

[Updated]

Still not working :P Sorry if I annoy anyone... (I have made some testing:)

So... with the default values, I open the Alchemy scene without having any item in my inventory. The Alchemy window it's empty and when I press Enter or C or Space on an empty space, I got the following error: Script 'Alchemy_Script' line 132: NoMethodError occurred. undefined method `name' for nil:NilClass. The X or ESC keys work if I want to get out of the Alchemy window or I want to remove an item.

Problem 2: If I have more than 2 or more items (for example: 2 High Potions) I got the following: Script 'Alchemy_Script' line 464: NoMethodError occurred. undefined method `draw_hemming_text' for #<Bitmap:0x134fb50>. Do I need some extra pictures in the Graphic directory?

Problem 3: I wanted to create an Bronze Helm ALCHEMY_OUTCOMES = [ [0, 10],... (line 50) and I need 1 High Potion and 1 Full Potion: ALCHEMY_RECIPES = [...[[0,2], [0,3], 0, 0], ] (line 42). Then I enter the game, I take one of each potion, I select them in the Alchemy window, and when I press the Z key to craft the item: Script 'Alchemy_Script' line 464: NoMethodError occurred. undefined method `draw_hemming_text' for #<Bitmap:0x130a478>

The Blueprints window work, I can see all the blueprints and if I modify the item requirements for an item that needs to be crafted in the script, it shows the ingredients properly in the Blueprints window. I haven't tested yet how to learn a blueprint because I saw that there was one with a lot of ????????'s 

I really hope that I will get the script to work because it remembers me of the crafting system in Anarchy Online and that's a good one with lot of potential in RMXP games :D

the  ? ? ? marks are just a filler for the recipes, for just the ones that are unknown.

also i have updated the script.  and your not annoying anyone. (well least not me)

thanks for helping me fix my mistakes, it will help me become a better scripter.

YAY! It's finally working   ^-^  Cheers Mr_Wiggles! and keep the good work coming :D It was a pleasure to criticize you (erm.. helping you :D)

:) thanks, good luck with your game.

Here is an quick update suggestion:

1.) Make somehow that some items can be made only if you are near or staying on an event. For example you can brew potions only if you are standing near an alchemist's bench, you can cook only near a fire source, etc...

2.) Make that some items don't disappear from inventory after you used them in a craft. For example knife + book = slashed pages, the book will disappear from inventory as default but the knife not. Or you can add multiple results from crafting, for example knife + book = slashed pages and knife.

I don't know if the suggestion NR.2 is already included in the script, I didn't had the time to experiment to much with it, and if it is, tell me please how to make it work :D , I don't have to much free time atm...

since when is alchemy crafting?

@ Firerain - idk

@  recon2009 - nice suggestions when i get the time i can try to implement them into a new version.

I got the script working but i have 2 problems
1) potions no longer appear in my invetory (but appear in the alchemy list wen picking ingrediants)
2)game crashes after battle giving this error


????????NameError?????????
unitialized constant Interpriator::Scene_plan_alch

I'm currently using
Blizzards Tons of Addons, Final Fantasty 7 Menu and Blizzard Chaos Limit Rage Scripts and they work fine together

@ Firerain - As long as you can combine two or more items of your wish, that's crafting :P the possibilities are unlimited...

What script in blizzards Addons are you using?

i looked at the scripts that you where talking about and i didn't find anything that would make them not work together.  Where in the scripts data base did you put this? (above main bellow the defaults, is it above or bellow these other scripts or not, that kinda stuff)

I placed the 2 scripts directly above the main script and underneth the rest of the custom scripts i'm using

(https://rmrk.net/proxy.php?request=http%3A%2F%2Fi278.photobucket.com%2Falbums%2Fkk85%2Fapoclaydon%2Fth_rgpxperror.jpg&hash=5a548b75fb120d644626317bb408419704df45a4) (http://i278.photobucket.com/albums/kk85/apoclaydon/rgpxperror.jpg)

Fixed the crashing i think i just forgot to remove a previous alchemy a call script but the pottions still dnt show in the item menus but they do show in the alchemy windows

what ff7 script are you using i looked one up but i there might be more then one version what i think is happening is that the windows used in both scripts to show the items are sharing the same name.

yh the scriot is
http://www.rpgrevolution.com/forums/index.php?showtopic=18488

Try to place the alchemy script above all of your add on ones.

still dsnt show potions in inventory (snt matter gonna redo the database anyway so i'll leave slot on blank)

wow! this is awesome! thanks for posting it. I will defenitly use it in my game.
All I need to learn now is how to add and change some recipes. felt a bit wierd that a High Potion + High Potion will create a erm Bronze Helm?
And that an Iron Shield + High Potion +  Steel Spear will create a Full potion.
Ah well I hope that I will be able to undearstand how to create my own recipes.
Still new to scripting have only made games without extra scripts befour so well I am a noob a guess.
If I am to stupid to understand how to fix recipes I will come back and ask. And thank you again for making this awesome script.

Oh NO! got a problem..

Made a test char with a list of event commands that looks like this
@>Show Choices: Show Recipe list, Time for Alchemy
: When [Show Recipe list]
  @>Script: $scene = Recipes_List.new
  @>
: When [Time for Alchemy]
  @>Script: $scene = Alchemy.new
  @>
: Branch End
@>

well it works fine. when I choose the show recipe it shows the recipe list
and when I choose the Time for Alchemy option I get the Alchemy window
and I can create an item or two.
but if I create an Item and then talk with the guy again and choose Recipe list I get an error message that follows

Script 'Recipe' line141:NoMethodError occured.
undefined method `name' for nil:NilClass

did you talk to him after you created every item you could? and are you using the latest version of the script?

Well I am using the script that is posted in this thread. And I have recreated the script and the character but as soon as I create an item the "show recipe" option makes the game to crash and I get the message

Script 'Recipe' line141:NoMethodError occured.
undefined method `name' for nil:NilClass

I can talk with him again and create more items but I can't check the recipe list again.

yea i found the time to fix this, but i'm not on my computer so when i get internet on it again i can upload the new version of the script.

thanks I will be waiting

*Updated the script*

Hey Mr. Wiggles I get this error Script 'Alchemy' Line 37: NameError occurred uninitialized Constant ALCHEMY::Keys. I was wondering if u could help me fix and possible to add it to my menu screen

OH sorry that's my bad, i am useing an Input module in my game so i have some extra keys i can use. To fix this just go to that line and where it says "Keys::SHIFT" Change that to any one of RPG Inputs...
#----- Button -------- #
#  A B C X Y Z L R    #
#------Key Borad ----#     The equivalent on the keyboard.
#  Z B C A S D Q W  #         
#--------------------------#

So "Input::A" would be key "Z" and so forth. (yes you have to have Input:: before your desired button)

For adding it into your game menu you'll have to edit a little bit in the menu script and a few others.

Hello, Mr. Wiggles.  This seems like it would be a great addition to any game.  However, I am new to scripting and am having some problems with the script.

First of all, there is absolutely no text on any of the items or descriptions in the alchemy menu.  Only the icons appear.  How do I fix this?

Also, when I try to load the Blue Print list in-game using a $game_system.add_blue_prints( ), I get a bad syntax on line 354 "undefined method 'size' for 'nil:NilClass'  What am I doing wrong.

I can't wait to get this script working and use it for my game.  Great job!

hey mr wiggles, iv had a few probs but iv managed to fix them by reading the forum so this question hasn't been asked before (I think...). For some reason i cant add any knew recipes, like combination's of stuff to make you know? its a syntax on line 56 please help i also tried shifting the default down a line and added my own in between and it still says the same thing so i think that iv missed something that tells the computer how many recipes there are maybe??

i will look into these errors when i find the chance i was gone for 3 weeks RL stuff and getting into college classes, chances are i will look at these errors this week end.

[edit]
   @Yggdrasil12 - you need to put the blue print number for the blue prints your adding to the list of known ones. IE add blue prints 4 you would
$game_system.add_blue_prints(4)
or like to add prints 15
$game_system.add_blue_prints(15)

[edit2]
  @dewm3734 - ca you post what you have on that line so i can see what is wrong with it.

Don't know if you even come here anymore, but Mr Wiggles, I'm having a problem with the call script command for the blueprints. When I try to add a recipe, I get a message that reads, line 357 NoMethodError occured
                             undefined method `size' for nil:NilClass

Any thoughts?

Yea sorry about the delays, but i do check this forum from time to time for support on my scripts, i have updated with a newer version which i think fixed all the problems.

Thanks, it works great now.

this is annoying me. This script keeps putting all it's info on one line in my script editor. I'm quite frustrated. Also, the screenshots don't work anymore on this topic.  what is going on?  :-\

The img urls expired and i have no clue why its putting all the script information on one line.

It's because SMF code-boxes and Internet Explorer do not mix. It works on pretty much everything else.

I don't have a clue why, but the recipe book script isn't working for me anymore. It worked when I was first using it, everything that my characters learned to make in the alchemy script would show up just fine. I haven't done anything to any other scripts or added any new ones, but now when I try to call the recipe list, I get a message reading, "...line 123 NoMethodError occurred. Undefined method `[]' for nil:NilClass.

I know it can't be a problem with your script, I just want to determine where the problem lies. 'Line 123' is in the "Draw Item" section of the script. What does that pertain to, anyway? If I know, then I can probably find the problem.

Okay, never mind. I don't know what the hell is going on, but I got it working. I needed to keep a blank line between my last creatable item and the line that says
"]# needs to be here" in the alchemy script for the recipe script to work. I don't know why exactly...I never had to do that before...

So you do in fact have this working? Also there is an edit button for your previous post and i know not using it makes mods here angry, just saying.

Help, I keep on getting this error:


Script 'Recipes' line 139: NoMethodError occured.

undefined method 'blue_prints' for #<Game_System:0x83ccd30>


I am a noob and have no idea how to fix this error. HELP!

I can fix your error but you'll need to wait till tomorrow, i don't have the time right now to fix it. I just wanted you to know that i know about it.

Thanks I'll be waiting! ^-^

Mr. Wiggles?
Is anyone there? :-\

An error like that is probably caused by a corrupt save file. Does the project work in a new game?

Nope, I get the same error! :'(

Aaaaaahhhhhh!
I have a new error:
Script 'Alchemy' line263:NoMethodError occured.
undefined method `include?' for nil:NilClass
Help
I think I'm going crazy, I keep seeing errors everywhere :aryan:

HEY, is anyone there?

Yep, im here, and im looking into replicating the error so i can fix it.

[edit]
Can you post what your script header looks like?
