Can't Get Inventory to Work

Cr4shBarcode 1 month ago in Inventory updated 3 days ago 5

I can't get my Inventory Module to work. Items will not add to or appear in inventory. In the sample scene, nothing appears in the merchant list. There is one error, a NullReferenceException. If anyone can instruct me how to get things working, that would be great.

Unity version:
Game Creator version:
1.0.2
BAD, I'M UNSATISFIED

It didn't work; nothing changed. Here is the error message.

Fixed

Unity has an internal tool that (theoretically) updates the old prefab system to the new one. The Inventory module was designed with the previous one, but we assumed the upgrading tool would do the trick.

However, seems there is a bug in their tool what prevents from correctly upgrading the prefab tool. But, there should be a solution. First of all, if you're not using the latest Inventory module, could you update it? There shouldn't be any incompatibilities.

Once you're on the latest Inventory module, click at the top tool bar and select Asset -> Reimport All. Beware that this operation can take between a few minutes up to an hour, depending on the size of your project. With just the default Game Creator package, however, it should be around 3 to 4 minutes long.

This will force Unity to run the prefab upgrade tool again. Let me know if this works or not.

Reimporting all the assets didn't work; I'm not sure why this was marked as "fixed".

I've updated a ticket and pumped the priority. I'll be working on an update next week and this is one of the things I'll be investigating asap. Not sure why this is happening, but I'll circle back as soon as I have more info.

Cr4shBarcode I've been looking at this and haven't been able to reproduce this. However, due to a Unity bug, a user suggested that the prefabs weren't correctly updated. Might it also be that the Preferences Window doesn't shop the Inventory tab?

If that's the case, could you try navigating to the Plugins/GameCreatorData/ folder, right click it and select Reimport. This will take less than a minute. Restart Unity (just in case) and it should be working. If not, please let us know.

Did not work. Again, this is my error. Please compare it to what the script is supposed to look like and tell me if mine is different somehow:
