I have a project build for a series I am trying to perfect and what I would like to do is get a block that will take a specific item (in my case wheat) (if you could make it customizable that would be even better) use it and then activate the block as a button. I can make a texture for it after the fact, but I have no clue how to mod this and I have looked everywhere for a mod that would achieve what I am trying to do ( put in wheat and have the dispenser dispense flour from a mod that I have.

any help would be greatly appreciated,
