melee turtle help?

I dont know lua, and i just want to make my melee turtles stand there and attack I have conveyor belts leading mobs through them, can someone help me? and make the items drop infront of it?

while true do turtle.attack(); turtle.drop() end

should do the job.

One then with the turtle.drop command, it drops in front of the turtle, place a chest above/below then use

 turtle.dropUp() ; turtle.dropDown() 

respectively

The OP asked for the items to be dropped in front; however, yes, if a different direction is desired, then up and down are both available as well.
