This jsbin has two problems. To use it, click “collection”, then first (on the right hand side) create a “gene”. “1 1 1” are good entries for the three text boxes. Then click the “add to snake” button. The phrase “Morph: Normal” should change to “Morph: Computed Morph” (real code to be added later). What confuses me is the count changes (Locus count) but not the analysis of the contained genes in the array newSnakeGenes.
Second, try to delete the gene you created with the “X” button, the code runs but the gene does not leave the array (at least as far as I can tell)?
