Strafing is moving laterally to the direction the player is facing. This is one of the best ways to dodge enemy fire, move unpredictably, and watch multiple directions while moving in a straight line.

There are several notable forms of strafing. Circle strafing is moving continually around an opponent, becoming difficult to track. Jittering refers to strafing rapidly over a short distance, making it difficult to judge one's position. Finally, air strafing is a form of acceleration that allows players to move laterally in the air.

Circle strafing

Circle strafing.

To circle strafe is to move around your opponent. The technique is performed with the left and right strafe keys in combination with the mouse holding your aim on on the target. When combined with jumping, it can make oneself quite difficult to hit.

If your opponents have poor aim, poor mouse sensitivity, or lose track of you, you gain the opportunity to shoot them easily while dodging their fire.

Projectile attacks have to lead your motion. Sentry Guns cannot lead. MONOCULUS can lead somewhat when angry.

Jittering

Tap the left and right keys very rapidly, with slight variations in rhythm. This causes you to jerk side to side, encouraging opponents to fire outside your position as they try to aim ahead. This technique sounds ludicrous in theory, but in practice, you become more difficult to hit with any hitscan weapon.

Air Strafing

Air strafing is the technique of combining the strafe keys and mouse movements to change your direction in mid-air. Its primary use is to reach a destination that is hidden around a corner or barrier, but it also slightly increases the velocity of the player and can be used to dodge aerials and avoid successful juggling.

Air acceleration

Players who use any of the default movement keys while in the air produce a short impulse in that direction. This is what allows players to arrest mid-air motion or move a small amount after being knocked into the air. The acceleration is capped or else the player would accrue airspeed while holding or tapping the movement keys.

Explanation

To air strafe, a player air accelerates to one side while smoothly turning the mouse in that direction. This change in orientation changes the direction of your attempted air acceleration relative to the actual direction of motion, and the component of air acceleration in that direction becomes less than the acceleration cap. This small difference between the component and the cap allows a small amount of further acceleration to occur, and you move slightly in that direction. Thus, a smooth continuous mouse movement ensures that you are always below the acceleration cap and capable of accelerating to that side. This transforms your path through the air into a smooth curve.

Technique

Here are the practical steps:

• You move forward through the air;
• You hold one of the strafe keys and none of the other movement keys;
• You smoothly turn the mouse in the direction of the strafe key.
• Repeat to the opposite side.

You accelerate a little bit and curve through the air in that direction. If at any point you press the forward key, back key, or turn in the opposite direction of your strafe key, you cap out your acceleration, or stop dead, and end your air strafe.

Make sure to release the forward key (default key: W) whilst airstrafing.

Trivia

• Air strafing is an artifact of the air acceleration system developed for the physics engine for Quake. In related games, strafe jumping, bunnyhopping, and wall hopping are all exploits of the same acceleration cap. Source uses a similar physics system.
