Inventory Help

Recommended Posts

Well I'm currently having a bit of trouble with my inventory. Ive got the data side of things down and packed, each character contains a bag class which holds itemIcons. And so far I've been able to get 1 inventory control working(Generalized inventory HUD) with drag and drop.

But my question is what do I do if i want multiple inventory controls where the player can drag and drop items between the two. Ive tried having the inventory controls output all the positions of their slots but then when I drag the inventory everything just moves out of place. anyways here is my current inventory code.

InventoryControl.cs:

If you need anymore information about the system or any more code files just ask.

I don't think anyone has time to go through all your code to analyse it. If you want help, you should try to explain what you're trying to do in your code instead of posting it. You may even find the answer while doing it. Also, did you use the debugger to try to find why your coordinates are wrong?
