(SOLVED) how to make a check if there is an entity with an item in the right hand nearby

Make a procedure, and create a local logic variable. Use an entity iterator bracket with your desired radius, and check if the item in the main hand of the entity iterator is your desired item: if it is, set the local logic variable to true. Entity iterators check all entities in their radius individually, but by using a local variable, it will turn the check to true if any of them have the item in their main hand.
