Null string referenced error in VerbCoin template

[Adrian]

Hello everyone,

I have several problems with the AGS buit-in VerbCoin Template which I will explain in seperate posts. Here's the first  one:

When I open the inventory window and execute an action (look/talk/interact) on an inventory item, I get an error message: Error running function 'repeatedly_execute': Error: Null string referenced"



I searched the forum and found similar threads, like these:

but I think my problem is still a bit different.

I use the Verbcoin module version 1.1 by monkey_05_06 in addition and did not change any code. My AGS version is 3.2.0.

The error already occurs when I hover the mouse over the inventory item before having the chance to release the mouse button. The error does NOT occur when I put any strings in the inventory item's custom properties "Custom_Interact", "Custom_Look" and "Custom_Talk". But I don't want to fill in custom properties for every single invertory item. So there seems to be a problem with the default values for inventory items or something.

Does anyone know how this could be fixed?

Although I am unfamiliar with this module, I think I can see what's up. If these are custom properties, there's a way to edit the schema so there's a default value. Double click on any item, go to properties, click "edit schema", find the property you want (eg "Custom_Look") and double click. Then in the default value type something like "Inventory Item" or whatever generic message you want to be displayed.

I hope that works!

Thank you, geork!

With your method there's no error message any more and the game works accurately.

But is there a way to automatically include the items name or description in the property, to make them less generic, like "Propery Custom_look: 'Look at %item description%'" for example?

Thanks again for helping me with this!
