[Trigger] Prevent players to build on specific areas

[Huder]

On my map players can build a flag called "Territory sign". I want to prevent players from building in places near this flag. Only player who own this flag can build near it.

This trigger will look like this:

• BuildTerritoryCheck
  • Events
    • Unit - A unit Begins construction
  • Conditions
  • Actions
    • Set TempLoc = (Position of (Triggering unit))
    • Custom script: set bj_wantDestroyGroup = true
    • Unit Group - Pick every unit in (Units within TerritoryRange of TempLoc matching ((Unit-type of (Matching unit)) Equal to Territory sign)) and do (Actions)
      • Loop - Actions
        • If (All Conditions are True) then do (Then Actions) else do (Else Actions)
          • If - Conditions
            • (Owner of (Picked unit)) Equal to (Owner of (Triggering unit))
          • Then - Actions
          • Else - Actions
            • Unit - Remove (Triggering unit) from the game
    • Custom script: call RemoveLocation(udg_TempLoc)

And all is fine except one. Player is loosing resources if he is build in wrong places. I want refund back all his resources. Unfortunately there is no action such as unit - unit Gold Cost and unit - unit Wood cost so i don't know how to do this.

If you rather use Unit - Kill or Unit - Cancel, the player will get a refund based on what the refund ratio is under Gameplay Constants.

 

[Huder]

I don't see Unit - cancel action
Killing unit don't give refund.

Oh dear.

There's another workaround: you can detect when a builder is ordered to construct the building. The order string is the unit's raw name.

So make a new trigger; event - generic unit is ordered targeting a point
then put every building in the map in a unit type array, and check whether the order is any of the listed buildings, if it is, order the builder to stop.

I see strange problem. If i make that trigger:

• kill
  • Events
    • Unit - A unit Is issued an order targeting a point
  • Conditions
  • Actions
    • Unit - Kill (Triggering unit)

Unit will die and this is working, but if i make:

• stop
  • Events
    • Unit - A unit Is issued an order targeting a point
  • Conditions
  • Actions
    • Unit - Order (Triggering unit) to Stop

or

• hold
  • Events
    • Unit - A unit Is issued an order targeting a point
  • Conditions
  • Actions
    • Unit - Order (Triggering unit) to Hold Position

Unit is still moving. Why?

 

[rulerofiron99]

Try Unit - Move unit to position of unit, and see if that works.

This is crashing wc3

• trig
  • Events
    • Unit - A unit Is issued an order targeting a point
  • Conditions
  • Actions
    • Unit - Order (Triggering unit) to Move To (Position of SOME_UNIT)

This is working but after teleport unit still trying to reach previous point order.

• trig2
  • Events
    • Unit - A unit Is issued an order targeting a point
  • Conditions
  • Actions
    • Unit - Move (Triggering unit) instantly to (Position of SOME_UNIT)

I think in first trigger wc3 is entering into infinite loop that why is crashing. Because Order to move to another unit is
a "Unit - A unit Is issued an order targeting a point" too

 

[rulerofiron99]

Replace unit with itself?

 

[Huder]

Hmm unit stops, that might be good starting point to my new trigger.

 

[rulerofiron99]

Another method would be to list each building's gold and lumber costs in arrayed variables, and refund based on that after removing the unit.

Yet another method I found:

• Actions
  • Selection - Select (Triggering unit) for (Owner of (Triggering unit))
  • Game - Force (Owner of (Triggering unit)) to press Escape/Cancel

Thanks my trigger is done.
I checked what order string is for building things by this function:

• Game - Display to (All players) the text: ((Name of (Triggering unit)) + ( + (String((Issued order)))))

And i get that results:

smart is when you are moving and those custom_**** are building orders. It seems like each building has his own string.

So my whole working trigger look like this:

• BuildTerritoryCheck
  • Events
    • Unit - A unit Is issued an order targeting a point
  • Conditions
    • Or - Any (Conditions) are true
      • Conditions
        • (Issued order) Equal to (Order(custom_o00A))
        • (Issued order) Equal to (Order(custom_h001))
        • (Issued order) Equal to (Order(custom_h00P))
        • (Issued order) Equal to (Order(custom_h00S))
        • (Issued order) Equal to (Order(custom_u000))
        • (Issued order) Equal to (Order(custom_h01B))
        • (Issued order) Equal to (Order(custom_u006))
        • (Issued order) Equal to (Order(custom_u005))
        • (Issued order) Equal to (Order(custom_h00N))
        • (Issued order) Equal to (Order(custom_e000))
        • (Issued order) Equal to (Order(custom_e00B))
        • (Issued order) Equal to (Order(custom_e00A))
        • (Issued order) Equal to (Order(custom_e00C))
        • (Issued order) Equal to (Order(custom_e00D))
        • (Issued order) Equal to (Order(custom_e00E))
        • (Issued order) Equal to (Order(custom_e00F))
        • (Issued order) Equal to (Order(custom_e00G))
  • Actions
    • Set TempLoc = (Target point of issued order)
    • Custom script: set bj_wantDestroyGroup = true
    • Unit Group - Pick every unit in (Units within TerritoryRange of TempLoc matching ((Unit-type of (Matching unit)) Equal to Territory sign)) and do (Actions)
      • Loop - Actions
        • If (All Conditions are True) then do (Then Actions) else do (Else Actions)
          • If - Conditions
            • (Owner of (Picked unit)) Equal to (Triggering player)
          • Then - Actions
          • Else - Actions
            • Unit - Replace (Triggering unit) with a (Unit-type of (Triggering unit)) using The old unit's life and mana
            • Selection - Select (Last replaced unit) for (Owner of (Triggering unit))
    • Custom script: call RemoveLocation(udg_TempLoc)

And this is fine.
