default parameters cause Editor error

[michael_pm]

Hi, I just bought and imported NodeCanvas, so latest version. I am not clear where I can check which version it is. This is a similar issue to what is reported with nullable float (http://nodecanvas.com/forums/topic/issue-with-nullable-float), but has to do with Action nodes calling script functions that take default parameters in C#. I have a function RequestPath(Vector2 target, float priority = 0). If I add an action node to call that the editor barfs in the reflection code. Call stack below. If I remove the default 0 for priority everything works fine.

InvalidCastException: Cannot cast from source type to destination type.

I am using NodeCanvas 2.3.8. Sorry, its hard to see/read since its black relief on a dark background.

Hello,

Please specify that the default parameter is a float, by adding literal f at the end and it will work 🙂
RequestPath(Vector2 target, float priority = 0f)

Cheers!
