Tell us what’s happening:

I’ve read all the other forum posts about this step, but i still can’t get the right answer.

Your code so far

if (collisionDetectionRules.every((rule) => rule === true)) {
  player.velocity.y = 0;
  return;
}

<!-- file: index.html -->


/* file: styles.css */


/* file: script.js */
// User Editable Region

if (collisionDetectionRules.every((rule) => rule === true)) {
  player.velocity.y = 0;
  return;
}

// User Editable Region

This part of the statement is a surplus. The ‘if’ statement already checks if every rule in the array is truthy.

thank you for your help @DobarBREND - i have now passed the step

can you explain what this part actaully means though - (rule) => rule ?
