How to update Codec for extension of Abstract class?

[stin23]

I am creating a new class which extends FoliagePlacer. I would like to add a new argument to the constructor, but that is giving me problems with the Codec definition for the class.

public CustomFoliagePlacer(FeatureSpread fs1, FeatureSpread fs2, int height, CustomTree customTree) {
        super(fs1, fs2);
        this.height = height;
        this.customTree = customTree;
    }

The new argument is a custom type so it's not possible to add it as you would like 

Codec.INT

Is there a way I can update the Codec definition so I can use this new argument?

You don't, the entire point of the codecs is that it knows what type its constructing.

You'll have to make your own codec.
