In Cooking Chaos on Roblox, “roll” appears to mean rolling for classes rather than a physical move in-game. The game description says you can “roll for classes to help unlock your true chef potential,” which is part of the class/perk system rather than a movement mechanic.

How to roll

  1. Open the class/roll area in the game.
  2. Use your Gems or any roll currency the game requires.
  3. Spin until you get a class.
  4. Equip the class and use its perks in matches.

What the roll is for

Rolling gives you a class that changes your kitchen abilities, and the game page also mentions perks and appliance upgrades to help you cook faster. A guide on the game says Class Rolls are one of the main uses for Gems, so codes and rewards often help players get more rolls.

Controls that help

For actual movement and interaction, the listed controls are:

  • Interact / pickup / drop: E on PC.
  • Throw: Left Ctrl.
  • Use item: Mouse button 1.
  • Activate perk: 1, 2, 3, 4.

If you meant something else

If by “roll” you meant a different action, like dodging, tumbling, or a special class ability, the game’s public descriptions I found only clearly confirm class rolling.
