weird bug.

[JesseParticipant]

I have a class in which I created a field for a class. the problem was that I create it as null:

Monkey

[crayon-5cba154b98d61456838251 inline="true" ] Class Button2 Field pos:PVector2D=Null Field x:Float Field y:Float Field text:String="" Field width:Float Field height:Float Field offx:Float Field offy:Float

1 2 3 4 5 6 7 8 9 10 11

[crayon-5cba154b98d61456838251 inline="true" ] Class Button2 Field pos:PVector2D=Null Field x:Float Field y:Float Field text:String="" Field width:Float Field height:Float Field offx:Float Field offy:Float

[/crayon]

it parse and translates fine but when it tries to compiles I get this error:

***** Fatal mx2cc error *****

Internal mx2cc build error

I could not figure it out after trying to solve it for a couple of days. finally I started trying it out by process of elimination and found out that it was the = Null in the field. I removed it and it works fine now. I know I don’t need to initialize a with a null but still, I don’t think it should be giving me that error.

another thing is that I tried to create a minimized sample code to post it but it works fine. No errors. even with the “=Null”.

Anyway, I just thought I would mention it. I would have post it to Github but I don’t want to post a 15 file with over 5000 line of code just to present the problem or post a zip file.

Is PVector2 a struct? If so then I suspect this is a “Structs can’t be null” bug of some kind, in which case I guess the parser should probably pick it up.

[JesseParticipant]

no this is one of my old monkey1 classes, I was just converting the code to monkey2. it’s a regular Class none have a structure involved.

This may in fact be fixed in develop branch – someone had a similar problem with image:Image=Null in a struct and I seem to remember fixing it.

If you post a runnable example I can test it…generally, it’s always best to post something runnable if something is acting up.

[JesseParticipant]

as I mentioned above, I tried to create a small program to illustrate the problem but I wasn’t able to reproduce it. I think it has to do with the order of the #Import of files and how they are processed by the compiler. just a wild guess.

Anyway, I am not sure if what I am running is the developer ver. or the Master ver. I think it’s the Developer ver. I’ll try again. If I can duplicate it with small code, I will post it. Thanks Mark.
