Hoping for suggestion of what to change

Some time back there was a change to RMC (forget when this started) and my custom module for Creatures of Middle-earth started throwing errors for every NPC.

Just looking for what I need to fix.

This module was hand-coded back before RMC was based on Core-RPG, and it was working ok for a while, but then started getting these errors when I open any of the NPCs.

Code:

Is there something I can do to quickly get things working again?

All of the controls that are listed as having a type mismatch are type="string" in the current ruleset. You'll need to do a find/replace within your module db.xml file to set the current field type to string.

I don't know what type is used in your module, but here's an example if the size field in your module is type="number": <size type="number">0</size> should be <size type="string">0</size> So, you could find <size type="number"> and replace with <size type="string"> - check what type needs replacing in your code for the various fields listed in the error message.

I originally copied what was in Creatures & Treasures, one of the modules included with RMC.

I'll go through the ones I have and compare them to C&T and see what is different.

Thanks for the pointer for that.


Probably going to need to go through to find out what the new values need to be.

Seems like it was changed from the numbers being translated to a text type to straight text.

Not a big deal, just some digging necessary

All fixed now, thanks again Trenloe

Glad you got it sorted out.
