Invited back to teach game dev after the UI design workshop
Deconstructing the Game Loop: Teaching State Logic in Scratch
How returning to Al Anshar to teach game development turned abstract conditional statements into tangible, joyful mechanics.
"When you teach a student how to build a game, you're not just entertaining them; you're teaching them how to break an overwhelming problem into small, manageable logic blocks."
From Static Design to Dynamic Worlds
Having previously taught mobile UI design to these same students two months prior, returning to introduce Scratch felt like a natural graduation from static layouts to living, dynamic systems. I explained that every video game is simply an endless conversation between the player's fingers and the computer: 'Check input, update position, check collisions, redraw screen.' That conceptual framework gave them a structured way to think about logic.
Overcoming Collision Frustrations
The most common stumbling block was collision handling: students would script an obstacle, only for the character to pass right through it or get stuck permanently. Walking them through condition boundaries line-by-line demystified the bug: 'The computer checks collisions so quickly that if you don't reset the coordinate, it thinks you're still touching it.' Seeing their faces light up when their collision scripts finally registered cleanly was immensely rewarding.

- Health / Lives Decrement Variables
Score Systems & Game Balancing
Engineering variable score counters, coin collecting mechanics, and tuning speed variables to make games fun.
- Score Variables & Sound Cues
- Difficulty Scaling Over Time
- Winner & Game Over Screens
Reflections on Logic Teaching
Insights on teaching sequential algorithms through play.
Bugs are Opportunities for Logical Insight
When a sprite behaves unexpectedly, walking students through the sequence of blocks turns frustration into an exciting detective puzzle.
Curiosity is Self-Sustaining
Once a student understands how to make a character jump, they immediately want to figure out how to make enemies chase them. The teacher simply provides the map.
