Virtual Class Declaration errors

[peterigzParticipant]

Was just updating TimelineFX to work with 1.08 and getting an error in the c compiler “constructors cannot be declared virtual [-fpermissive]”. So what I was doing was putting Virtual after the class name which as a result is now complaining that the “New” method cannot be declared virtual (worked ok before). Is there something I can do to make the New method not virtual or will I have to just start putting virtual after individual methods instead?

This code replicates the error:

Monkey

Class Test Virtual Field test:Int Method New() test = 1 End End Function Main() Local t:=New Test End

1 2 3 4 5 6 7 8 9 10

Class Test Virtual Field test:Int Method New() test = 1 End End   Function Main() Local t:=New Test End

Thanks!

I must’ve broken something – will fix.

Ok just committed a potential fix for this, although you’ll have to rebuildall or rebuildmx2cc.

I have a similar problem. With v1.02 it compiled fine. Current version gives this error:

Super class ‘fanotmX2.cftTween.TweenEquationCall’ has no default constructor

If I add a New method to it, it still gives this error.

You need a constructor in the “TweenEquationCallLinear”

thats the error I get when I try to check for errors. I added the “Method New()” and the error went away.

For safety purpose you should add a default constructor to all of your classes. if you don’t you might run into something similar when you try to implement something similar with other classes.
