[RC] KGlobalShop XP

KGlobalShop XP

Release Candidate 2

by Kyonides Arkanthes

Introduction

Normally any in game shop would only offer products or let you sell something to get rid of that nasty junk that has been filling your bag for quite some time. This script wants to allow you to sell them to a Global Shop. By global I mean it's a shop event you usually create but it won't eat the items you sell there as a hungry monster. Instead it will keep them and they will be available for other gamers.
Yes, my dear game developers! This is all about letting you exchange items between game saves!

Since this is a Release Candidate, most of the promised features are currently implemented. Still, I do need somebody to test it for me.

Yeah, I know. People often claim I should do it myself, and I am not really against it. What happens here is that experience has taught me how important it might be to let people that think as some (amateur) game developer to fiddle with it. You see, they do not share the same thoughts so their expectations could be different from the very beginning. This is what might cause the surge of weird and unexpected bugs that otherwise would not have been discovered because, well,  the scripter is used to use the script as intended so he does not make the same mistakes as the average user. Plus there are other users that love to break a script or a whole game just for the sake of it.

List of Currently Available Features

• Your usual list of shop goods
  
• Default or custom price modifications of items
  
• Separate script calls that allow you to set those prices, either for sales or purchases
  
• Hide or restore shop goods! 
  
• List of transactions, both sales and purchases - not displayed on screen right now 
  
• Automatically saved data, you still can save it manually if deemed necessary
  
• An empty help window

Terms & Conditions

Since it's a Release Candidate, you'd need to send me a copy of your game if you include two of my scripts.

Update

I've modified the script once more and wanted you to test it if you've got some spare time to help me debug or improve it.

List of Currently Available Features

• Your usual list of shop goods
  
• Default or custom price modifications of items
  
• Separate script calls that allow you to set those prices, either for sales or purchases
  
• List of transactions, both sales and purchases - not displayed on screen right now
  
• Automatically saved data, you still can save it manually if deemed necessary
  
• An empty help window
  

I wouldn't mind  if you send me sketches showing me how the menu or a specific part of it might look like.
