Help Needed! Stones for dinner

[Getura]

First thing - please excuse my bad english, I'm doing my best, but I still have much to learn.

 

So, I'm doing a character mod, and I need my character to be able to eat some normally uneabible stuff, like stones or cut grass, while still be able to consume normal food.

 

I tried to copy strings from WX's and Rock Lobster's lua, but looks like I did it wrong, as either the game crashes or my character lose the ability to eat normal food.

 

So can someone help me with this?
