Build 2048 in the Age of AI

Merging Tiles and Scoring

Explore the development of the merge_row function for 2048 to apply game-specific merge rules correctly. Learn to generate detailed specifications with AI help, implement and test the function in Python, and understand how merging combines with compressing rows to effect game moves.

We'll cover the following...

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 again to achieve the final row state. ...
