SOLVED 2.3.4.583 YYC Compiler Not Working With Visual Studio 2019

[Game_Re_creation_Project]

I have encountered a strange bug. I reported this bug several weeks when VS 2019 became a requirement (I was already using 2019 and had had success with the YYC) but the new update did not address.

It is as if the YYC does not "see" a constructor.

Using target VM:
Create Event:

event_inherited();

show_message("Is Seen 0"); //A message to ensure that this code is even seen at runtime.
//Get data structure for this control
try {
struct_scrollBar = new basic_Scrollbar_componets(id);
}
catch (e)
{
    show_message(e); //e is NOT reported at compile time using the VM or YYC. Hence, we may conclude there is NO error...
}
finally {show_message("Is Seen 4");}//A message to ensure that this code is even seen at runtime.
show_message("Is Seen 5");//A message to ensure that this code is even seen at runtime.
ScrollBar_Design(struct_scrollBar);

Constructor:

function basic_Scrollbar_componets (_id) : basic_Control_componets(_id) constructor
{
#region OPERATION
    show_message("Is Seen 1");//A message to ensure that this code is even seen at runtime.
    
    //Scrollbar inputs and outputs
    large_change    = _id.Large_Change;    //When the user clicks on the Background of the scrollbar
    small_change    = _id.Small_Change;    //When the user clicks on the Decrease or Increase Buttons
    input_maximum    = _id.Maximum;        //The input_maximum value the scrollbar can output
    input_minimum    = _id.Minimum;        //The input_minimum value the scrollbar can output
    input_value        = _id.Value;        //The value input by the user to inform the output of the scrollbar
    output_maximum    = undefined;        //An adjusted version of the input_maximum
    output_minimum    = undefined;        //An adjusted version of the input_minimum
    output_value    = 0;                //An adjusted version of the input_value. The output_value is returned as the value of the scrollbar
    precise_scrolling            = _id.Precise_Scrolling; //Enables the Bar Button to jaggedly drag if true, smooth with padding after button release if false
    scroll_drag_end_pad_type    = _id.Scroll_Drag_End_Pad_Type; //Pad type after smooth Bar Button dragging button release
    
    //We'll skip the rest of this for this example... Note that "Is Seen " 2 and 3 are further down in the constructor. They are there ONLY for demonstration purposes to ensure that they are seen at runtime

At runtime, the "Is Seen" messages report "Is Seen 0" ... "Is Seen 5" -- All show_message() functions return a string in a textbox, meaning that all code is seen.

Switch the target to YYC and ONLY "Is Seen 0", "Is Seen 4", and "Is Seen 5" return message boxes. It's as if the constructor is not included in the compilation. Errors apparent to the constructor not being called then ensue.

Has anyone else encountered an issue where the YYC is not creating new constructors?

I don't see a definition for basic_Control_componets in what you've posted. What happens if you put some debug statements in there?

Also

//e is NOT reported at compile time using the VM or YYC. Hence, we may conclude there is NO error...

That's not how compile errors work.

That's not how compile errors work.

basic_Control_componets() is a parent constructor which contains variables shared among all user controls in my project. I didn't think it would be necessary to directly reference it here.

Interesting about the try-catch block. I thought e was reported at compile-time. I guess it is only at run-time...

I placed debug statements in the parent constructor and they WERE seen but it was a bit wonky. I should have seen the messages repeat for each button in the scrollbar but the messages were seen only once.

Again, this project worked in 2.3.3 but in 2.3.4 there are unexpected issues.

basic_Control_componets() is a parent constructor which contains variables shared among all user controls in my project.

As in, global variables? Or common struct variables?

I didn't think it would be necessary to directly reference it here.

It is referenced, though. It's the parent constructor. It's a thing that runs between two messages, the first of which displays and the second of which doesn't. If I see something get to point A and not get to point B, the things between A and B are the first suspects. You're welcome to do your own debugging, but if you're asking for help, you need to ask the whole question.

Then it's a fair bet that it's only running the function once. The question of why that might be happening is, again, something you have consciously decided not to equip anyone but yourself to answer.

Sorry if I'm being too esoteric, I was EXTREMELY rushed last night...

basic_Control_componets() is just a global constructor, as are the constructors for the scroll bar, command button, etc. (They are called in script modules.) I do not know why the function is running only once and frankly lack a means of equipping anyone to answer. I suspect it may be the vcvars32.bat file associated with Visual Studio. I am presently on a different machine which never had VS installed. It is a lengthy install, however, and I'll provide an update when finished. If a fresh install fixes the error, then it likely has something to do with my VS install on my other machine. I will then have to completely wipe any ruminants of VS and do a fresh install. I did read in the update documentation for 2.3.4.583 that VS 2019 is now a requirement for using the YYC target. There may be residual conflicts of some kind since I have had 2015 installed as well.

In the meantime, here are some videos demonstrating the scrollbar. (Ignore the low in-game frame rate--it has subsequently been fixed):

Installed fresh VS 2019. No difference in error. I'll have to dig deeper to see what's happening here... I'll type in my results and a solution here once I discover it.

Just downgraded to 2.3.3.574 and it works! So, there must be something about how 2.3.4.583 compiles constructors... I wish I was more versed in the deeper terminology and could render a more useful description of the problem.

I see that you have chosen the "tell, don't show" option. Functions "called" in "script modules" will, in fact, only run once. That would be true no matter the subversion of 2.3 you're using, though, so I believe that you're not using the right words here, still. A good choice of words to use would be "copy" and "paste", as in "copy the code from your actual dang game and paste it here so people who aren't you, i.e. the people you're asking questions of, will have the tiniest chance of being able to provide useful information in return." That's what I meant by being equipped to answer your question. Equipped with any knowledge at all of your problem.

I wish I was more versed in the deeper terminology and could render a more useful description of the problem.

Ctrl-C, Ctrl-V. It's not rocket science. It's barely even computer science.

Lol! Someone's getting frustrated and needs a hug... While I can sympathise, I would request that you try and politely ask that they copy/paste the actual code and don't let frustration get the better of you...

This would indeed suggest (A) that there is either a bug in the current version, OR (B) that there is a bug in your code that is only being detected in the current version. So, I would have to agree with @Nidoking and request that you copy/paste ALL the relevant code so that we can examine it and determine which of the two scenarios it is. If it's a bug in the runner then YYG will have to know about it, but you don't want to file a bug report only to find out it's your own code that's at fault, that just wastes everyone's time.

The recent update did not solve my issue, hence I feel a bit more justified in copying and pasting the amount of code which will be necessary to ask this question.

Note: when the new operator is called, only the inherited constructors are seen. When the new operator is not called, the parent struct is seen and other errors related to the struct NOT being a constructor are then thrown later on in the Create event. This project also complied again in 2.3.3.574 but still refuses to work properly in 2.3.5.589...

I seem to have run into a 50,000 character limit with this post (hence, why I didn't want to post all this code in the first place!)
I will truncate to the code to provide the basic gist of it...

//Create event for the scrollbar

event_inherited(); //Contains inherited values which are not assigned in the constructor

show_debug_message("create " + string(5)); //I have placed debug messages with their respective lines to ascertain what the compiler sees
//Get constructor for this control
//NOTE: Removing the new operator makes it so the YYC actually "sees" the struct but then other errors are introduced...
struct_scrollBar = new basic_Scrollbar_componets(id); //<--This is where the bug occurs. The actual parent constructor for the scrollbar.
show_debug_message("create " + string(8));
ScrollBar_Design(struct_scrollBar); //The script which builds the scrollbar based on parameters obtained in the constructor.
show_debug_message("create " + string(10));

//Set Scrollbar's bounds
control_bounds_xx1 = struct_scrollBar.xx1; //If the new operator IS NOT called, these values then throw an error. If the new operator IS called, the compiler doesn't even reach this line.
control_bounds_yy1 = struct_scrollBar.yy1;
control_bounds_xx2 = struct_scrollBar.xx2;
control_bounds_yy2 = struct_scrollBar.yy2;

//The remainder of the Create event is irrelivant for this question...

Next, the Command Button constructor is called (the buttons on the scrollbar are considered command buttons)

    //Button Specific
    button_render_button    = true; //Sets whether the Command Button is rendered

}

Lastly, the parent constructor for the scrollbar object which gets/sets the values for the scrollbar.
This IS NOT seen if the new operator is used in the Create Event:

I have even added semi-colons to the closing brackets of these constructors to no avail.

Possible issue: Can the updated YoYo Compiler handle nested constructors? The parent constructor calls new constructors within itself...

The error is then thrown in ScrollBar_Design() because the array containing the vertex data is not properly populated.

There was no indication of this in the IDE. I changed these variable names after noticing that they changed color in my forum post and voilà!
