Zap dashing in Rocket League is an advanced technique that allows players to quickly change direction while maintaining momentum. It is performed by pressing the boost button and then quickly pressing the air roll button in the opposite direction. This causes the car to do a sharp turn in the air, allowing players to quickly dodge opponents or line up shots.
Zap dashing is a very useful technique, but it can be difficult to master. Players need to be able to time their inputs precisely in order to execute it correctly. However, once mastered, zap dashing can give players a significant advantage in Rocket League.
