How to pick items?

How to pick items in a circle around a certain unit?

Hmm, I'll try to make some trigs in one second.

• Item - Pick every item in (Playable map area) and do (Actions)
  • Loop - Actions

Should do it.

That's a bit big, i meant like within 200 range around a unit. And the only way i found it was to pick in a region. (Which is square)

i think you cannot use a circle region here, but sth like this:

• Set tempregion = (Region centered at (Position of (unit)) with size (200.00, 200.00))
• Item - Pick every item in tempregion and do actions
  • Loop - Actions
• Custom script: call RemoveLocation(udg_tempregion)

Ok thanks. Guess i'll have to live with it.

you can then run a filter to get if all the items in the square are in a circle.

That some jass thing?

I tried this one with

• Unit - Order (Entering Unit) to right-click (Picked Item)

That works as long as there is only one item in the region. More than one item and the unit won't pick it up.
But i don't know if there is a better solution...

You use simple maths to get the distance of the item away from the unit. If it exceeds your circle's radius then it is not in the range you want it to be. Thus you basically ignore all items via an if statment that have a distance greater than the circle's radius as it loops though each item.

The maths you need to know is Pythagoras' theorem as WC3 uses an X and Y grid and thus forms a right angled tri-angle between the points.
