Merging Tiles and Scoring

Explore how to generate detailed specifications for merging tiles in 2048 and implement the merge_row function in Python with AI support. Understand the mechanics of combining adjacent tiles, scoring the moves, and testing your code to ensure correctness. This lesson prepares you to handle row merges accurately as part of building the full game.

By the end of this lesson, you will:

  • Generate detailed specs for merge_row(row: list[int]) -> tuple[list[int], int] with the help of AI.

  • Understand the exact 2048 merge rules (especially tricky cases like [2, 2, 2, 0]).

  • Generate code for the merge_row function, with the help of specs.

  • Test the AI-generated code.

  • See how compress_row and merge_row will combine to create a full left move.

Merged tiles in row when the left arrow key is pressed, score updated by 4
Merged tiles in row when the left arrow key is pressed, score updated by 4

If you look at the illustration closely, we can compress a row to the left, then merge any adjacent tiles that can be merged, and compress ...
