In a scenario, I'm trying to set up two sets of unit orders - the first that covers the first several turns, then a second set once a turn-based trigger fires.

I've attached the unit's AI configuration (for the Axis player, #1). This is the LUA code from the script
I know the trigger fires, but I cannot tell if I have a Lua error or if I'm setting the new orders correctly.

Is there something obvious I'm missing? Is there a better way to change unit orders that isn't documented in the API?

I'm still having issue with changing unit orders. I've looked at several scenarios where this happens, and I'm not seeing what I'm going wrong.

I've uploaded a copy of the scenario, in case someone has time to see if I've messed up something obvious.

Thank you.

function OnTurn12()
    for id,unit in pairs(world.units) do
        if unit.owner_id == 0 then
            local orders = unit.orders
            local newOrders = {};
            local i = 2
            while(orders[i]) do

This looks like a LUA written by either someone who knows LUA but has zero clue about PC2 specific LUA or chatGPT.
U are using several "commands" that just do not exist in PC2 specific LUA.
Here is an example for a function that will remove the first command of a list of units.

I had rewritten the logic in the Lua script since my original post. I've also modified the first order, in case the use of Default for the first order was causing the issue.

Looking at the Lua code you provided, and my updated code, the only difference I see is that I didn't use parentheses in the if statement. I based the new code on the Orlik_active() method in the PanzerCorps 1 scenario "Bydgoszc"

I freely admit that Lua isn't a programming language I'm comfortable wit. I isn't my first, or even tenth programming language, but I'm not the best with scripting languages, even with the Lua manual.

LUA for PC2 is very diffrent than LUA for any other programm since all but the basic LUA commands are derived from the C++ the main programm, in our case PC2, is written in. since we have no acces to that tzhe only available hints are in the Properties.txt u can find in the editor folder of the game. if u are used to programming this should help a lot.

in general in PC2 u need 2 LUA functions to fire a script. 1 trigger and 1 execute.
In ur case the trigger would look like this:
function IsTurn12()
return world.round == 12
end
All it does is check the condition and if it´s met fire the execute.
U put it here in the editor:


Then u have the execute function, like i posted earlier and put it here:


Then u set the editor to check evry turn if the condition is met:


like this on turn 12 the first order will be removed from the order list of the unit.


Those 2 lines a gibberish. variable "orders" is not set anywhere. it could be unit.orders, but i doubt that append is a viable command here.

while(orders) do
newOrders.append(orders)

hope this helps.

The trigger is set up properly, and fires as expected. This is the current code dealing with the order changes. The removal of the air units works successfully, as does the final tutorial message. Only the order change is failing.

Code: Select all

function Turn12Condition()
    return world.round == 2
end

Just a hunch. try this and let me know if it works now.

I tried it, and the orders haven't changed even by turn 5. Thank you for the idea.

In an odd way, I feel better that I didn't miss something completely obvious when someone like you looks over my scenario.

hard to say what might be wrong. if u want provide the files and i have a look.

This is the latest copy of the scenario, with the last recommended change.

if the count is set to 1 it will only check it once. if u set it to 0 it will check evry turn.

Let me know if this was it.

The trigger has been firing, and I get the tutorial message at the end of the function. Setting the count to 0 still didn't change the orders.

working fine for me. if u want the units to only move and do nothing else check those.
