You're Welcome.

I did it! Thanks for your help

Ok, so it's under 'Main.Config > Combat > Dweller Weapons'. You need to add your weapon to the list there.

As far as weapons, you are right, you can't just duplicate the weapon. There is another section you need to edit to tell the game you have added another weapon. I can't remember where it was, but there is a list of current weapons and you need to add the one you have made to the list to have it be recognised as a weapon.

That's so regret. But I still have a question, how to make new weapon work? When I
equip the weapon I made, It always show me a fist. But your Golden Gun and Weapon Pack are working normal. Did you remember anything about your modified beside item itself? I don't think that you just duplicate them.

I'll be honest, i haven't modded this game in a very long time. I've pretty much forgotten how I made them. However, I don't remember doing anything special to get the character to say something after they take them. Pretty sure I just made a duplicate of the existing Pills in the game and then edited it to do what I wanted. Can't remember doing anything out of the ordinary.

I notice that when dweller use your meds, they will talk after used; such as "These pills are really helping! I should be well soon", and so does the Morphine.
I try to make a same thing, and I reach the same cures effect as yours, but them won't talk after used.
I already found the text path which them talked, but I don't know how to connect them, could you tell me how you modified?

Oh ok thanks.

Unfortunately it is a bug of the mod tools. When creating new items with new names and descriptions, they don't show once the mod is uploaded to steam.

Needs to be fixed by the devs.
