Day 12 is a path-finding problem. Writing a Breadth First Search in C++ is totally in my wheel house, and I am so I go with that.

Day 11 is all about the big numbers, and doing it in Unreal didn’t help me at all. Some horrible input handing, and some nasty gotchas. It’s all in C++.

After two days of C++ I think its time to get back into Blueprint for Day 10.

Day 9 of Advent of Code has chain of elements following each other on a grid, and as with Advent of Code in Unreal Engine Day 8 I have stuck with using C++ and a TDD-lite approach, within Unreal.

In day 8 we are looking at a grid and comparing the heights of trees in four directions, along the column and row, first to determine visibility, and then to calculate a “scenic score”.

For Day 7 I will be misusing Unreal’s scene graph as a proxy for the file-system hierarchy described by the puzzle.

After yesterdays Blueprints it’s time for a C++ palate cleanser with a side order of Unit Testing.

With the components set up, one for each stack, parsed from the puzzle input, the remaining lines from the puzzle are processed one at a time in the actor Event Tick.

Day 4 has us splitting a string into 4 integers, and then implementing some range-tests. This presents no serious complications in blueprint.

It is a Saturday morning, and I want to get this finished before I go about my day, so my first step is to write some C++.
