That's not really possible currently. For some weapons, it could be done, but for any that don't already have their own bespoke tooltips it's impossible to add new ones. And I don't really want to leave something half done because it looks sloppy and breaks immersion.This is an awesome pack. An idea I have for it it to add the DPS of the weapon, maybe at the bottom of the stats. I'm not sure how possible this would be with the variable stats in the game from armor sets and whatnot, but I think even a base DPS without any of the modifiers might be useful when comparing weapons. Just an idea for you, have a good day!
Same reason I didn't add anything to grappling hooks and minecarts. For some I could, but for most I can't, and I decided I'd rather be consistent. If you want it then you should go bug Re-Logic to add empty tooltips to every item.
I don't know anything about modding, and tmodloader currently doesn't support language packs. So unfortunately no. Once the updated tmodloader comes out, I'll check if there's anything I can do to get it running on it but I think you'll be able to just install it the same way as on vanilla.This looks great, but is there any way you can add it to tmodloader?
