Sonnet 3.7 + think could write me a rotating box /w ball in day 1 but not now

Discussion

hi.

in day 1, Sonnet 3.7+think is the ONLY one that can do this in python,
while grok3+/-think, DS R1/V3, o3-mini, gemini etc failed.

Write a Python script using Pygame that creates a square window of size 500x500 pixels with a black background. Inside this window, display a white square of size 300x300 pixels that rotates continuously around its center at a speed of 60 degrees per second. Within this rotating square, include a red ball with a radius of 10 pixels that starts at the center of the square and initially has zero velocity. The ball should be affected by gravity (300 pixels per second squared downward) and bounce off the walls of the square, following basic physics rules for reflection (i.e., reversing its velocity component perpendicular to the wall upon collision). Ensure the animation runs smoothly at 60 frames per second.

on day 1, the ball wont be out of the box.

is this due to “temperature” in LLMs?

i am sorry i dont have the screentogif around, otherwise i’ll post a moving gif instead.

btw, here is the working code on day 1,
