Editing Instructions Step By Step (section)

===== Loop Entities(Range) =====
This is used to look for things within your units visual range (default is 15) and uses filters to narrow what your looking for. In this case the only filter used is dropped items this will look for items on the ground and piles of resources as well. For this loop you also need to set the range it's looking for you can set it as high as you want but it will only be able to see as far as the unit can which without other modules is 15, however you can set it a shorter range and it will limit what it returns. If you don't set it remember it's not nothing it acts as zero (range) so you will get no returns.

For every item it finds it will output an entity (not a data type but a set of data types) into the variable 'A' and then flow to the next instruction through the upper tether node.
