[IronPython] The return value (out)

[Afan Olovcic]

Thanks for your help guys,
It works ,
I have another problem now ,
i have new error msg : :)    expected TEntity, got TPivot  but I know why .
TPick is struct :

 public struct TPick
    {
        public TEntity entity;
        public TEntity surface;
        public float X, Y, Z;
        public float NX, NY, NZ;
        public int triangle;
    }

that is why he expect TEntity
but TMesh, TPivot, Tlight etc All of them are TEntity in same time
in c or c# I can say  Tlight light  or TEntity light     TMesh mesh  or
TEntity mesh
do you guys have idea how to solve this problem

Thanks
