Pointers and struct children in vex

Recommended Posts

Hi there, I am trying to define the shape of lightning using vex in a wrangle sop

A lightning path has forks that split from any given path, creating other paths with almost identical properties to the main path. To that end I created a path struct but I can't figure out how to get it to store its 'forks'. The same issue would arise if I instead stored the parents instead of the children.

I am defining a path of lightning as so:

struct lPath
{
    lPoint source;
    lPoint sink;
    float energy;
  
    lPath forks[];
    
    void setSource(lPoint newSource)
    {
        source=newSource;
    }
    
    void setSink(lPoint newSink)
    {
        sink=newSink;
    }
    
    void setEnergy(float newEnergy)
    {
        energy=newEnergy;
    }
    
    void create()
    {
        addprim(0,"polyline",source.num,sink.num);
    }        
}

my issue is that I can't include a reference to itself due to infinite recursion, which is why in c++ I would use a reference

lPath * forks[];

Is there any way to solve this using vex?

Kind Regards

George
