It is not that overengineered, i trusted that live coding compiles stuff (when there are no errors or warnings). Yes it was dumb trusting tool-chain will complain. My code never was compiled and run since error occurred, until i found out that live coding compiles but code is not updated.
No casts in that function, it was just calculating offsets for hexagonal map (so pure int fun).
And yes after 2 weeks it kind of overengineered.
