#[Twitter thread] by Oskar Stålberg: More video game talk prep. Gonna have another go at persuading people to cut their tiles along the dual grid instead of the main grid. I genuinely don't understand if this is rare because people don't know about it or if there is some drawback I'm not seeing.
Most gameplay logic (like collision and navigation) should still happen on the main grid. And all object-like sprites, like characters, houses, etc, should also go on the main grid.
Again. You should definitely keep both concepts around in your code. Most gameplay will still happen on the main grid. The dual grid is mostly for field-like background tilesets
Correction: The 4 fundamental features are Fields, Houses Rivers and Roads. I forgot Fields, which is ironic since that's what the rest of the thread is about. Terrain is a type of Field.
