Making a pet-like companion eater?

[AkaiNight]

I am trying to make a companion who is a crafting station and im trying to make her upgradeable with an item and i think the easiest way to do it is adding eater component but the problem is she is not eating anythign not just the custom item i made( i tried it with my character its eatable food) but not even normal foods. I don't know what im missing(i checked critters and woby files for it).  I think problem is about interactions beacue even im near her the items should be able to craftable with certain tech is not craftable too (but i can craft them with c_freecrafting() code so i think item is fine and problem is about companion). So any help would be great. I am leaving companion's code let me know if there is anything else u need and it would be helpful if u know any tutorial or similar code like it.

It seems you have her diet set to meat. Were you trying to feed her meat?

@AkaiNight Try using a FOODGROUP instead of a FOODTYPE. That seems to be what is usually done.

I would suggest starting with a basic eater that can eat standard character food and work your way to what you want. If even the basic eater fails, I am inclined to believe you have other key issues at hand.

The problem is i don't know how to make a basic eater its not a character and I think its not about eating because as i mentioned it should be a crafter on its own but this feature doesn't work. Its first time im making a companion and i don't know coding (just tying to understand while making and im trying to find similar modes i want and i try to edit them)
