ITEM CRAFTING

Overview
This script adds an item crafting system to the game.
Crafting recipes are set using note tags.

For example, if you wanted to be able to distil 5 potions to make a Hi-Potion, you would add this tag to the Hi-Potion item's Note:
<craft item:1:5>

And to allow a hi potion to be diluted to make 4 potions from it using the breakdown system, you would add this tag:
<craft break item:1:4>

That makes it possible to create hi-potions through the crafting menu if you have 5 potions in your inventory.

And break hi-potions into potions through the breakdown menu:

Features

Usage
To install the script, open the script editor in RPG Maker VX Ace.
Scroll to the bottom, and select a blank row between Materials and Main Process.
copy/paste the script code into the right hand editing pane.

For any item you want to be craftable, you need to add at least one craft tag to its note.
Each craft tag specified one ingredient of the recipe to create the item.
The tags are as follows:

Tag	Meaning
<craft item:id>	Consume 1 item with the specified id
<craft weapon:id>	Consume 1 weapon with the specified id
<craft armor:id>	Consume 1 armor with the specified id
<craft item:id:number>	Consume a number of items
<craft weapon:id:number>	Consume a number of weapons
<craft armor:id:number>	Consume a number of armors

With these tags, you have the basic crafting system.
If the player has the ingredients you specified, they can craft the item.

But maybe you want the player to find recipe books or need specific tools to craft items.
This is also possible with two more note tags:

Tag	Meaning
<craft tool:id>	The tool must be in inventory to craft, but is not consumed
<craft recipe:id>	The recipe item must be in inventory, or this item will be hidden from the crafting menu

These are pretty similar in function, which one to use depends if you want the player to be able to see the recipe or not.

If you want to use item breakdown as well as crafting, the tags are similar:

Tag	Meaning
<craft break item:id>	Give 1 item with the specified id
<craft break weapon:id>	Give 1 weapon with the specified id
<craft break armor:id>	Give 1 armor with the specified id
<craft break item:id:number>	Give a number of items
<craft break weapon:id:number>	Give a number of weapons
<craft break armor:id:number>	Give a number of armors
<craft break tool:id>	The tool must be in inventory to breakdown this item
<craft break recipe:id>	The recipe item must be in inventory, or this item will be hidden from the breakdown menu

Finally, do you want the crafting menu to be available all the time?
If not, there are restrictions you can set by editing the configuration variables at the top of the script.
You should use the IDs from your game database.

Variable	Effect	Default
MENU_COMMAND	Addto the game menu	true
MENU_COMMAND_TEXT	Name of the menu command	Crafting
MENU_COMMAND_ENABLE	Always enable the menu command	true
MENU_COMMAND_SWITCH	Enable the menu, if a switch is on	0 (disabled)
MENU_COMMAND_ACTOR	Enable the menu if a specific actor in the party	0 (disabled)
TEXT_INGREDIENTS_TITLE	Heading for the ingredients window	Ingredients:
TEXT_INGREDIENTS_TOOLS	Heading for tools in the ingredients window	Tools:
TEXT_INGREDIENTS_PRICE	Heading for price in the ingredients window	Tools:

Configuration for the breakdown system follows the same pattern, in the "module CRAFT_BREAK" section.
It is therefore possible to enable only one system, or have different conditions to enable each one.

Crafting shops

Perhaps you want to have crafting performed at a shop?
Perhaps you want different shops to be able to craft different things?

Both of these are now possible.
First, we need to add note tags to the items:

Tag	Meaning
<craft gold:amount>	Price to craft this item
<craft break gold:amount>	Price to break down this item
<craft switch:id>	Show this recipe only if the game switch is ON
<craft break switch:id>	Show this recipe only if the game switch is ON

If you want the same items to be craftable at every shop, you can ignore the switch.
However the switch lets you make a blacksmith, alchemist, etc, each of which can craft different items.
Switches can also be used to enable new items as the player progresses through the game. If you specify multiple switches in a recipe, all of them must be on.
(note that <craft switch> and <craft recipe> perform the same function, so you could use switches exclusively if you don't like using key items)

To launch the crafting from a shop event, you will need to use a script call:


And the equivalent for calling breakdown from an event:


Here is an example of a blacksmith's shop event:


I have given the halberd these notes:
<craft weapon:1>
<craft weapon:13>
<craft gold:100>
<craft switch:10>

And in the game, it looks like this:
