[HELP] How to pickup items without clicking

01-10-2008, 12:30 AM

I'm making an all keyboard control map and by all keyboard it means I can't click on items to pick them up. I've been toying with my Trigger Editor but I just can't find a way to create this. Basically I had this algorithm in mind:

1.Unit casts Pickup Weapon(Spell was based on Roar so that I don't have to target using my mouse).

2.Script will attempt to locate the nearest item from unit position.

3.a.If script detects an item, picks up the detected item and adds it to inventory slot 1(upper left slot).

3.b. If script does not find any item near the unit, prints a message saying "No weapons were found."

But I just can't find a way to make my unit pick up an item...

Help ASAP this is the final thing I need for my map.

JASS:

native          UnitAddItem             takes unit whichUnit, item whichItem returns boolean

Can't find it in GUI for some reason, seems very odd that it wouldn't be in there. If you don't know JASS, do this: make two variables, a unit variable called TempUnit and an item variable called TempItem. TempUnit will hold the unit picking up the item, TempItem will hold the item to be picked up.

Trigger:

Actions

Set TempUnit = (Casting Unit or whatever)

Set tempUnit = (Item being picked up)

Custom script: call UnitAddItem(udg_TempUnit,udg_TempItem)

Trigger:

Hero - Give (Last created item) to (Triggering unit)

Strange though how they have it in the 'Hero' subsection, considering regular units can have items too.

TaintedReality	Ahh. I looked under Item and Unit, but didn't think of Hero.

Elhyse	But how will I make my hero detect that there is a nearby item so that when I press my Pick Up Weapon spell, the hero will find the nearest item and then work your script.

Untitled Trigger 001

Actions

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

Loop - Actions

Try to loop through every item and get the X/Y coordinates of it, then compare the distances to the casting unit. The item with the lowest distance will be your closest. Mind you, you're going to have to create a region around the casting unit, which isn't very difficult, but remember to remove the region afterwards.

Sorry, I edited my post after learning that there was already a function for it :P

*edit*

Here, this is a snippet of what the code should kind of look like:

Trigger:

Untitled Trigger 001

Events

Conditions

Actions

Set TempPoint = (Position of (Triggering unit))

Set TempRegion = (Region centered at TempPoint with size (500.00, 500.00))

Item - Pick every item in TempRegion and do (Actions)

Loop - Actions

Custom script: call RemoveRect(udg_TempRegion)

The Custom script part is for removing the region (actually a rect) so that it doesn't leak. Hope this helps.
