Detecting "unit ordered to build" event

[Mendel]

Hey, i am trying to find away to detect when ever a unit is ordered to build a building, i belive it would be under the event "Unit - A unit Is issued an order targeting a point"?
than how the order is called?

i am trying to create a system which enables to build buildings in range of a point... if some one have any suggestions they are welcome :]

It's the name of the building.

• Trigger
• Events
  • Unit - A unit is issued an order targeting a point
• Conditions
  • (Issued order) Equal to (order(farm))
• Actions

This detects when a farm is going to be built

oh cool thx it works :], another one now i try to stop the unit from building, the result is the unit walks to build the building but as it starts it stops, i want it to stop from the beginning so it wont even walk to the direction

Yep, that is a bit tricky. You will need these triggers:

• Melee Initialization
  • Events
    • Map initialization
  • Conditions
  • Actions
    • Hashtable - Create a hashtable
    • Set Hash = (Last created hashtable)

• Build1
  • Events
    • Unit - A unit Is issued an order targeting a point
  • Conditions
    • (Issued order) Equal to (Order(farm))
  • Actions
    • Set Point1 = (Target point of issued order)
    • Unit - Create 1 Dummy for (Owner of (Triggering unit)) at Point1 facing Default building facing degrees
    • Hashtable - Save Handle Of(Triggering unit) as (Key builder) of (Key (Last created unit)) in Hash
    • Unit - Add a 0.01 second Generic expiration timer to (Last created unit)
    • Custom script: call RemoveLocation (udg_Point1)

• Build2
  • Events
    • Unit - A unit Dies
  • Conditions
    • (Unit-type of (Triggering unit)) Equal to Dummy
  • Actions
    • Set Builder = (Load (Key builder) of (Key (Triggering unit)) in Hash)
    • Game - Display to (Player group((Owner of Builder))) for 3.75 seconds the text: ...
    • Custom script: call IssueImmediateOrderById (udg_Builder, 0xD0008)
    • Unit - Order Builder to Stop
    • Hashtable - Clear all child hashtables of (Key(Triggering unit)) in Hash

Map Sample (you will notice that you cannot build a farm):

P.S. I will upload this as a system, along with more features.
P.S.2 The system is MUI.

hehe you did it all for me :]. it works perfectly! exactly how i imagined it, although i never thought it would be so complex. hehe well really thx!

hey, maybe u join me in my project??? ^^

I am having my exams this month. Not really able of cooperating

how does it work?
it creates a unit at the point where you want to build
but then it issues some secret cryptic order and then it issues a stop order
what for?
and it also is abuseable because it reveals a certain point

imho this would serve the same purpose but since I don't know how yours is working exactly I can't tell
I'm using an item with no model file so you can't pick it up and only see with drag selection
using a global item is better because every time you create a unit and remove it it will leak a little bit (leak can't be removed)

also blizzard is using this function to check if an order is a unit order it might be helpful for your system (just in case you don't know already)

function String2OrderIdBJ takes string orderIdString returns integer
    local integer orderId
    
    // Check to see if it's a generic order.
    set orderId = OrderId(orderIdString)
    if (orderId != 0) then
        return orderId
    endif

    // Check to see if it's a (train) unit order.
    set orderId = UnitId(orderIdString)
    if (orderId != 0) then
        return orderId
    endif

    // Unrecognized - return 0
    return 0
endfunction

Hah, really smart solution; never thought of that )

Well, the visibility is not an issue; change the owner of the unit to Neutral Passive/Hostile.
By the way, your way doesn't seem to be MUI. The item can be moved once at a time. What if two/three/more units are issued the exact same order simultaneously? Where will the item move?

I tested it with shift-click/wisp-detonate-abuse and 3 workers at once so I think it works fine
however I'll make a few other tests just to make sure
edit:
even triggered spam-build-orders are blocked fine

Ok, the best way to make the MUI test is having 3 preset units and pick them in a Unit Group and order (Picked unit) to make the action you want.
