This is the lesson where Eon stops describing programs and builds one, block by block.
The on-switch: the green flag
First he drags in the green flag block and puts it at the top. Now, every time he taps the flag, the whole program runs from the top. Think of it as the power button for your code.
Building a sequence, step by step
To get the cat to the center, Eon adds a "move right" block — but one step isn't enough. So he adds another, and another, testing with reset and play each time, until the cat lands just right (about two or three steps). Then he adds a jump.
Then comes the satisfying combo. Eon wants "go right, then jump, then go right, then jump." He arranges the blocks in that order, presses play — and the cat does exactly that. Wow!
The payoff
Here's the whole point his dad drives home:
"You don't have to drag the cat every time. You wrote all the instructions once — go right, jump, go right, jump. Now you just press play, and it follows your order exactly."
That's the magic of a program: effort once, results every time. And when a kid plays Eon's game and taps the flag, they get the exact sequence Eon designed.
Try it
Put these in order and predict the result: green flag → move right → move right → jump. (The cat scoots right twice, then jumps — every time you press start.)
