Summary

I'm looking for a script that allows the player to create items from other items similar to the synthesis shop in Kingdom Hearts. I have provided an image from Kingdom Hearts and a mock-up of what I'm looking for below. This shop takes items from your inventory to make a new item along with a small fee.The left window shows what resulting items can be made through synthesis with the gold or "coins" cost next to it. The right window shows the required items or "materials" to perform the synthesis...

This shop takes items from your inventory to make a new item along with a small fee.The left window shows what resulting items can be made through synthesis with the gold or "coins" cost next to it. The right window shows the required items or "materials" to perform the synthesis as well as how many of those items the player already has in their possession. The items to be created and the items to be destroyed should include regular items, weapons, and armors.


An added feature (not necessary, but cool) is that the game keeps track of what items the player has synthesized at the shop (marked "MIX" in the Kingdom Hearts picture) and the Synthesis shop itself will show more and more items available for the player to synthesize after they've created everything previously available.


Another bonus feature would be if the player has enough materials to make a particular synthesis item, the text of that item would be in normal color and anything the player doesn't have enough materials to make would be in a greyed color.


Other info: I don't think the Kingdom Hearts Synthesis shop charges a fee when creating items, but other synthesis shops like in Final Fantasy IX do charge a fee, so it would be cool to have the option. Also being able to see how many of the synthesized item you already have would be cool (in addition to the materials in possession). I've seen a script for a synthesis shop for VX, but not for XP. If anyone thinks they can make this and has any further questions, please ask me!
