Create a clone army

Use createClone to spawn copies of a sprite, then give each clone its own behavior with whenCloneStart.

// The original sprite creates 5 clones then hides itself
whenGreenFlag(() => {
  hide();
  repeat(5, () => {
    createClone();
  });
});

// Each clone bounces around independently
whenCloneStart(() => {
  show();
  changeX(Math.random() * 300 - 150);
  changeY(Math.random() * 200 - 100);
  forever(() => {
    move(4);
    ifOnEdgeBounce();
  });
});

Each clone starts at a random position and bounces around the stage on its own. The original sprite hides so only the clones are visible.

Note

Clones are deleted when the green flag is clicked again. To delete a clone manually from within its own script, call deleteThisClone().

Try this next

• Bounce off the edge — understand how the bouncing behavior works
• Animate a sprite with costumes — give each clone an animation too
