Events — Part 19
When key pressed or clicked, do an action. This is part 19 of 20.
What you'll learn
You will learn that events trigger actions, like dominoes — one thing causes the next.
Steps
- 1An 'event' is something that happens — like pressing a button, tapping the screen, or a program starting.
- 2In this code, the event is the program starting. Once it starts, it triggers a chain of actions: print Action 1, then Action 2.
- 3Think of it like a domino chain: one event (the push) triggers everything that follows.
- 4Games use events all the time: when you tap, the character jumps. When a timer ends, the level changes. Event → Action!
