Save units orders

[micca]

So I have a unit that has orders to move to a point, but under certain conditions I interupt that order by another order. I can save the original order in an order variable, but I don't know how to order it to perform that order in the variable.

Is it possible?

There are only "issue an order" actions, but they don't have an "order" type component.

LastOrder - Wc3C.net

I imagine the system I linked above uses these functions:

GetIssuedOrderId() <-- Use this in response to "A unit is issued an order targeting point/object/no target" and save it as a variable

Use these when issuing the unit to resume it's last order:
IssuePointOrderByIdLoc(whichUnit, order, whichLocation)
IssueTargetOrderById(whichUnit, order, targetWidget)
IssueImmediateOrderById(whichUnit, order)

Basically, whenever a unit issues an order you save the Issued Order Id and save the Type of that order (Point, Target, Immediate).

With this information saved you can use one of those 3 listed functions and plug in the saved Order Id to order the unit to perform the order.

Trigger Example:

• Events:
• A unit is issued an order targeting a point
• Conditions:
• Actions:
• Set OrderUnit = GetTriggerUnit()
• Set OrderId = GetIssuedOrderId()
• Set OrderPoint = Target point of issued order
• Set OrderType = Point

Then when you want to return to this point:

• Custom script: call IssuePointOrderByIdLoc(udg_OrderUnit, udg_OrderId, udg_OrderPoint)

I didn't show OrderType being referenced here but it would be used to determine which of the 3 functions you should use. Like, "If OrderType equal to Point then: call IssuePointOrderByIdLoc()"

And is it possible to get the point of the order the unit already has without the event?
I can have potentially infinite amount of units that I need to set the order for.

Don't think so. But it's fine doing it this way.

Just save those variables to each unit using a Hashtable or Unit Indexing.

Or use that system I linked (it is a bit dated though).

I've played around a bit with hashtables, but I just can't get it to work. What am I doing wrong here?
For test purposes I assinged number 5 to each unit, but the debug text in the second trigger shows 0.
So the custom script also doesn't work.

Create the Hashtable during Map Initialization. You only need 1 Table for everything.

And your custom script for
IssuePointOrderByIdLoc(whichUnit, order, whichLocation) makes no sense. You're ordering the unit to 2, which is not a valid order.

An example of ordering it to Move to the point: call IssuePointOrderByIdLoc( GetEnumUnit(), "move", LoadLocationHandleBJ(0, GetHandleIdBJ(GetEnumUnit()), udg_SaveOrders) )

"move" is the order string.

For testing purposes use normal GUI and just issue a Move order:

• Unit - Order (Picked unit) to Move To (Load 0 of (Key (Picked unit)) in SaveOrders)

Oh, yes. I'm stupid I didn't realize I create a new hash map every time the trigger runs.

As for the custom script it wants integer as a second argument, not string.
So I assumed it has something to do with order ID, so I gave it the ID of the order. But I don't really know. Doesn't matter will use the gui order.

It works fine now. The orders are restored perfectly, thanks for helping me.
