The Forever Loop

The forever block (Control category, orange) repeats the blocks inside it endlessly — until you click the red stop button.

When to Use It

A character that keeps moving across the screen.
A background that keeps scrolling.
Continuously checking for input.

Example

When 🏁 clicked → forever → move 5 steps → if on edge, bounce The sprite bounces back and forth forever until you stop the program.
