The First Time I Understood What a Game Loop Actually Was

I kept watching tutorials where people said, “Everything happens inside the game loop.” So I copied it like a spell I didn’t understand.

Then one night I noticed something.. my game was lagging like crazy. The screen updates, the movement, even the sound.. all out of sync. That’s when I realized: I’d accidentally put time.sleep() inside the main loop 😭.

After fixing it, I finally got what a loop really means.. not just repetition, but control over time and flow. That one mistake changed how I saw every project after.

So now I’m wondering.. what was your “aha” moment in coding?
