Firstly, I'd suggest spending some time in training mode to get a feel for the game's physics. Learn how the ball bounces off the walls and your car, and practice dodging (your second jump) into the ball to put extra power into your shots. Generally, dodging into the ball will hit the ball harder and lower to the ground, while driving directly into the ball is more likely to chip it into the air.
You should also try and get comfortable riding on the walls, as the perspective change can be a little tricky to control.Secondly, the default camera settings for Rocket League are horrendous. You should check out the camera settings of pro players to www.lolga.com find something that you feel comfortable with. Be sure to turn off camera shake as well.
While Rocket League is essentially car soccer, Rocket League Items plays more like hockey. When attacking (in Standard 3v3), you usually want two players actively trying to score and the third hovering around midfield. This third player either fills in the attack when a teammate falls back to collect boost, or is the first player back to defend against a counterattack.This concept is called Rotating, and is fundamental to every level of Rocket League play. There are plenty of resources on rotation, but I'd recommend Sunless Khan's video for a more in-depth explanation.
Rocket League players can now battle each other regardless of the system they playing on. Developer Psyonix rolled out cross-platform play support for the vehicular soccer game Monday across Nintendo Switch, PlayStation 4, Windows PC, and Xbox One.
