In my map a hero can only have one of various types of items, and I have a trigger set up to drop duplicates with a message that you can't carry extras (carried items are represented in the unit's custom value by an integer of base 2). Now, I need to set up a catch that checks if the item is being sold, and if so refund the gold cost of the item and remove it from play. The problem is, when I add a seperate trigger with the UnitSellsItem event, it's still dropped via the AquiresItem trigger. I tried checking if the "selling unit" value was null in the AquiresItem trigger, but apparently that value is only set in triggers with a registered event of UnitSellsItem (adding that to the event list didn't help either). Anyone know how I can intercept an aquire order, and if it's sold do different actions? Here's my trigger as it stands: Code:
[size=2]Aquire Shield
Events
Unit - A unit Acquires an item
Actions
If (All Conditions are True) then do (Then Actions) else do (Else Actions)
If - Conditions
Or - Any (Conditions) are true
Conditions
(Item-type of (Item being manipulated)) Equal to Shield
(Item-type of (Item being manipulated)) Equal to Iron Shield
(Item-type of (Item being manipulated)) Equal to Steel Shield
(Item-type of (Item being manipulated)) Equal to Mithril Shield
Then - Actions
If (All Conditions are True) then do (Then Actions) else do (Else Actions)
If - Conditions
((Custom value of (Hero manipulating item)) mod 2) Equal to 1
Then - Actions
Set temp_String = |cffffcc00Cannot carry more than one shield.|r
Set temp_Player = (Owner of (Hero manipulating item))
If (All Conditions are True) then do (Then Actions) else do (Else Actions)
If - Conditions
(Selling unit) Equal to No unit
Then - Actions
-------- If it wasn't sold, drop the item --------
Trigger - Turn off Drop Shield <gen>
Hero - Drop (Item being manipulated) from (Hero manipulating item)
Trigger - Turn on Drop Shield <gen>
Sound - Play HeroDropItem1 <gen>
If (b_Knows_Shield[(Player number of (Owner of (Hero manipulating item)))] Equal to False) then do
(Custom script: call DisplayTextToPlayer( udg_temp_Player, 0, 0, udg_temp_String )) else do (Do nothing)
Else - Actions
-------- Refund the gold cost and remove item --------
Custom script: call DisplayTextToPlayer( udg_temp_Player, 0, 0, udg_temp_String )
Player - Add (Integer((Life of (Item manipulated)))) to (Owner of (Hero manipulating item)) Current gold
Item - Remove (Item being manipulated)
Set b_Knows_Shield[(Player number of (Owner of (Hero manipulating item)))] = True
Else - Actions
Unit - Set the custom value of (Hero manipulating item) to ((Custom value of (Hero manipulating item)) + 1)
Else - Actions[/size]Code:
Drop Shield
Events
Unit - A unit Loses an item
Actions
If (All Conditions are True) then do (Then Actions) else do (Else Actions)
If - Conditions
Or - Any (Conditions) are true
Conditions
(Item-type of (Item being manipulated)) Equal to Shield
(Item-type of (Item being manipulated)) Equal to Iron Shield
(Item-type of (Item being manipulated)) Equal to Steel Shield
(Item-type of (Item being manipulated)) Equal to Mithril Shield
Then - Actions
Unit - Set the custom value of (Hero manipulating item) to ((Custom value of (Hero manipulating item)) - 1)
Else - Actions

Anyone? I mostly just need a way to distinguish if an item is picked up, vs bought from a shop. |

Maybe you could add a test in your trigger, check if player's gold lowers, this would tell you that he bought the item. |
