[AI] making computer pick up items

[PrisonLove]

how can i make a computer controlled unit pick up an item if it comes within lets say 400.00 of that item?

i have runes that spawn and i want to make it so that the computer picks them up if they come close to it. how do i do this?

This should work:

• Events -
  • Time - Every 5.00 seconds of game time
• Conditions
• Actions -
  • Unit Group - Pick every unit in (Units within 400.00 of (Position of Itemyouwant) matching ((( Owner of (Matching unit) controller) Equal to Computer)) and do (Actions)
    • Loop - Actions
      • Unit - Order (Picked Unit) to Move To ItemYouWant
      • Unit - Order (Picked Unit) to Right-Click ItemYouWant

and here is a test map I made that demonstrates this trigger:

This trigger will work and is already configured just replace the first condition in the loop with condition defining your item.

Trigger

• pickup
  • Events
    • Time - Every 5.00 seconds of game time
  • Conditions
  • Actions
    • Custom script: set bj_wantDestroyGroup = true
    • Item - Pick every item in (Playable map area) and do (Actions)
      • Loop - Actions
        • If (All Conditions are True) then do (Then Actions) else do (Else Actions)
          • If - Conditions
            • ((Item-type of (Picked item)) is A powerup) Equal to True
          • Then - Actions
            • Set TempPoint[1] = (Position of (Picked item))
            • Custom script: set bj_wantDestroyGroup = true
            • Unit Group - Pick every unit in (Units within 512.00 of TempPoint[1]) and do (Actions)
              • Loop - Actions
                • If (All Conditions are True) then do (Then Actions) else do (Else Actions)
                  • If - Conditions
                    • ((Owner of (Picked unit)) controller) Equal to Computer
                  • Then - Actions
                    • Unit - Order (Picked unit) to Right-Click (Picked item)
                  • Else - Actions
          • Else - Actions
    • Custom script: call RemoveLocation(udg_TempPoint[1])

Playable map area may leak I don't know I've never used it.

Just an idea here:

For speed reasons, I think that it'd be best just to add created/dropped items into a group (when one is picked up, remove it from group) and scan through THAT group instead of "pick all items in area/range".

I personally avoid "pick all items/units/etc." because they tend to leak, also using JASS instead of GUI is much more efficient if you're unit/item picking.

That is a good idea he should add them to group, but without the spawn item trigger I couldn't write a pick item trigger. So PrisonLove my code will work, but it you do what he said your map will run better.

I believe (Playable map area) does leak.
.
Better safe than sorry, put it into a variable and remove it via JASS
