What is wrong with this trigger, it gives me an error

[X-maul]

I keep getting this error when my trigger is run:
Error:

Trigger Error in 'gt_PreviewKarass_Func': Could not get 'triggerControl' from parameter in 'DialogControlSetPropertyAsBool' (value: 0)

The "Player" integer is set in a previos trigger and that should not be the problem.

It's complaining that you're using an invalid "triggercontrol"(which is just another word for "Dialog item").

In this case, I'd say it's because you're trying to do something to a dialog item variable that doesn't really refer to an actual dialog item. Imagine you created a "dialog item" variable called TestTriggerControl and tried to show it with the "Show/Hide Dialog Item" action. Since you haven't set it yet, it doesn't refer to a dialog item yet so it will give an error very similar to the one you got.

Now, why does this happen? It's hard to say without seeing all the triggers but you should check that all the variables actually refer to dialog items. You could start with printing out debug messages between each row so you can see which row it comes to before crashing. When you know which row it crashes on, print out the array indices you're using("Player" and possibly "x") before the row. Finally, check in your other triggers that you actually set the variable with those array indices to a dialog item.

How do I print debug messages? I checked all variables used in the trigger, and they are all set before the trigger is used.

 

[Siretu]

There's an action called "Debug Message". Even if the variables you're using for the array indices are set it doesn't mean the dialog item at that slot is set.

Let's say you have a dialog item array with the size 3 called "Foo". If you set Foo[0] to a dialog item, it doesn't mean you can do stuff to Foo[1] since it doesn't refer to something.

 

[Dave312]

Just an FYI - you can also use the debug window to determine the current value of variables. However currently this window does not display the values of arrays.

 

[X-maul]

Okay, I know it's not the same trigger, but it's more to make you show me how it should be done:
I got this trigger and it gives me 4 of those errors on map start (It is run on map start by another trigger)

How would you put those Debug messages and how should they look? they need some text and I dont know what to put there

NOTE: All the variables in here got array size of 5

EDIT:
Figured what was wrong with the trigger, but I'd still like to know how to use the debug action.

 

[Siretu]

Basically just enter any text in the debug message action and it'll write it out for you when it reaches that row.

If you have a trigger that's crashing but you don't know where, you can create debug messages between each row that looks something like: "Mark 1", "Mark 2", "Mark 3" and so on. Then when you run the trigger it'll spam you with those messages until it reaches the row that crashes the trigger and then you wont get any more messages.

So if it printed out all messages including "Mark 5", you know the error is after the debug message that prints "Mark 5".

 

[X-maul]

Well, as far as i know it does not crash? it just... well gives me an error and keeps on functioning?

 

[Siretu]

That instance of the trigger crashes(although it can still be run again later on). The game will keep on running.

 

[X-maul]

right now the trigger giving me errors looks like this:

• Preview Karass
  • Events
  • Local Variables
    • x = 0 <Integer>
  • Conditions
  • Actions
    • General - If (Conditions) then do (Actions) else do (Actions)
      • If

      • Then

        • Dialog - Hide Current Selection Button[Player] for (Player group(Player))
        • Dialog - Hide Current Text[Player] for (Player group(Player))
    • ------- Show
    • Dialog - Show Karass Select for (Player group(Player))

        • Dialog - Show Karass A[x] for (Player group(Player))

And it shows all the "Karass A[x]" and sets the "Current Ability[x]"
