Anti pickup system!

[Dorken]

Ok i really need help on this one.

I want a trigger that prevents units from picking up an item if they already got one item of that type in inventory.

Ive had several suggestions about making a trigger that drops the item when equipped.

But what i need is a trigger that PREVENTS units from picking up the item if matching conditions. Ask questions if i am unclear about something and rep + for help.

• Anti Pickup
  • Events
    • Unit - A unit Is issued an order targeting an object
  • Conditions
    • (Target item of issued order) Equal to item
  • Actions
    • Set TempLoc = (Position of (Target item of issued order))
    • Unit - Order (Ordered unit) to Move To TempLoc
    • Custom script: call RemoveLocation(udg_TempLoc)

I guess you can connect the dots, change the condition (you probably need to make an if/then/else-function with the conditions you want), the actions should work.

Edit:
Changed the trigger

Reason:
My previous trigger worked, but the hero (who wants to pick up the item) was ordered to stop - even if he was far away from the item.
That way, it would be hard to move through a field of items, with this trigger it's even easier than normally
It's also not really natural (a hero who stops the moment he tries to pick up an item),now he just moves to it, but never picks it up.

Here, I tested it, and it works:

• PreventItemPick
  • Events
    • Unit - A unit Is issued an order targeting an object
  • Conditions
    • (Issued order) Equal to (Order(smart))
    • (Target item of issued order) Not equal to No item
  • Actions
    • Set Picker = (Triggering unit)
    • Countdown Timer - Start Timer as a One-shot timer that will expire in 0.00 seconds

• Stop
  • Events
    • Time - Timer expires
  • Conditions
  • Actions
    • Unit - Order Picker to Stop

Ask if you have some questions.

P.S. If you're wondering why I used a timer, it apparently doesn't work directly (I tested that too).

Hehh, I just tested that myself and found that out
Though I think my trigger is easier =(

Well, doesn't really matter xD

Aww, I tested it as well
That's why I could edit my post

And I've given a reason why not to use stop

(doesn't matter, really xD)

Apoocylpse is right, his solution is better, when you have many items, as it would be hard to move because you would have to avoid clicking on items. In my solution the unit doesn't move at all if you click on an item it can't pick.

It really depends on what effect you want.
