Events — Part 6

When key pressed or clicked, do an action.

What you'll learn

You will learn that events trigger actions, like dominoes — one thing causes the next.

Words to know

Event: Something that happens (e.g. a tap, a click, a timer finishing). Events trigger actions.
Trigger: To start something. An event triggers actions to happen.
Action: What the program does when an event happens (e.g. show a message, play a sound).

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!
