[1.11.2] Is there a way to let forge know that only the modid changed?

[Kander16]

Hi,

 

I'm working on an update of my mod, which includes that the modid of my mod changes.

This means that my items / blocks aren't 'chef:item' but 'masterchef:item'. If I try to update my mod, when I log into a world where the masterchef mod was loaded before this update, forge says the items are 'gone'. (but they actually just have another modid).

Can I do something so forge will know that only the modid's have changed? Then upon log-in, the items/blocks won't be gone? Otherwise all the progress that people who update to the latest version of the mod will be lost.

 

Thanks in advance!

You should be able to handle FMLMissingMappingsEvent and use FMLMissingMappingsEvent#getAll to get all the missing mappings before remapping any with your old mod ID to your new one.

Thanks! I'll take a look at it.
