Datatree - Branch Count of direct descendant

For some data visualisation/ infographics I did a good while ago, there was the necessity to know the branch count of direct descendants at the different depths of the tree. So I don't mean just the final branches.

Starting at the trunk, I would need an integer of the number of direct descendants, so oh at the core: it has 3 branches, then the first branch of that, ah it has 5, the second branch to the trunk has 2, etc. yada yada.

Back then there was a script written for the specific one i needed and some funky string actions to help process. But I was always wondering, there must be a clean solution, has anyone come across such a thing?

I realize there is no component, but maybe someone wrote a script, uncovered a functionality?

Are you basically looking to find the number of branches that come out of each green circle?

Exactly that David!

This might be useful for someone.

To traverse the path in nested loops I do it like so:

Get the max number of branches at each depth by

int depthLayerOne = tree.Paths[tree.PathCount - 1].Indices[0] + 1;

int depthLayerTwo = tree.Paths[tree.PathCount - 1].Indices[1] + 1;

It gets the last element from the list of paths, which would have the max number of branches at each depth level as indices. I add one to those, to make it easy to loop.

I can do the 0 and 1 index into the 'Indices ' array because in my case I know the number of layers in my tree.

If you don't know that in advance you can use a list to loop through.

Nested looping like so:

for(int i=0; i<depthLayerOne; i++) {

for(int j=0; j<depthLayerTwo; j++)

{

// code

}
