Hello Guys, welcome to Rocket Science where
we try to solve the mystery of Rocket League’s physics and show the best ways
to use them to your advantage ingame. First up, Boost. In order to fully understand Rocket League
we need to lay the groundwork first. Boost is saved internally as an 8-bit unsigned Integer. What does this mean? Well Computers.
The important thing to take away from this is: Boost is a value between 0-255. The number that you see in the game is just a percentage calculated from this value. Knowing this, we can explain some seemingly
weird behaviour with small boost pads. In these videos you can see me going both
from 88% boost to 99% aswell as 88% to 100%. How is this possible? This is where the actual values come into play.
One small boost pad gives you 30/255 boost=11.76% On the left we’re going from 223 Boost to 253. And on the right we’re going from 224 to 254. 254 however is still not the maximum value,
allowing us to pick up another boost pad even though it looks like we’re already at 100% Second topic, Accelerating in the air Alot of players already know that it is possible to accelerate in the air without boost. This allows you to get just that little bit further in the air when running out of boost, which is great. However I wanted to research this a little more.
Here’s what I found. Acceleration works in much the same way boost does. This means you can not only accelerate
forwards but also upwards by pointing your nose up. Ofcourse the force is much lower
than that of boost and it’s not strong enough to cancel out gravity but in some cases it
does make a difference. In both videos I use the same macro to make
sure that the same actions are performed. The only difference being the acceleration
key. The car only hits the top if the key is pressed. There are more noticeable examples
of this but we will get to those later. Going backwards propels you
towards the back of the car. It should be noted however that the force
is lower than the one going forward. Jumping is similar to acceleration. If you went through the Rocket League tutorial
you know that holding down your jump button will extend the height of the jump.
While holding down the jump button there is a force active that pulls the car in the direction
of it’s roof, as can be seen from these examples. This force is only active for the first 250ms
after your jump. If you keep your jump button pressed longer than that
it won’t make a difference. After lots of testing I’ve come to the conclusion that the second jump in the air does not have this force at all. So you don’t have to worry about
keeping the jump button pressed there. Alright enough theory for now.
How do we apply this knowledge ingame? We can use it to figure out
how to jump as high as possible. Jumping creates creates an impulse
in the direction of the cars roof. That means tilting the car backwards by 90° instantly,
is going to render the second jump useless. When at 0 boost, the best way to use the second jump
is almost straight up. Because the force of acceleration in the air is so low,
the impulse of the jump is more important. Jump and hold the button for about a quarter
of a second while pulling your car backwards by about 10°,
then jump again and tilt all the way backwards. Make sure to accelerate the whole way
to gain the most height. If you have even the smallest amount of boost
this changes. Boost is much more powerful than acceleration.
Because of that it is worth it to tilt your backwards by about 30°
before the second jump. To gain the maximum height out of low amounts
of boost: Jump and hold the button for about a quarter of a second pulling your car backwards
by about 30°. Boost and then jump immediately to make sure the momentum of the second jump
carries over. Once again, make sure to accelerate whenever you’re not boosting to get to the
maximum height. Perfecting this motion will allow you
to touch the crossbar with 5 boost, land above the goal with 12 boost
or reach the ceiling of standard maps with 40 boost. This is a great example of how much of a difference accelerating can make. If you’re not accelerating,
you will fall short of the ceiling. If you have plenty of boost and you need to get up quick then you want to be holding boost down from the start. Because you’re tilting your car backwards after the first jump, the boost will start to push you up against gravity immediately. This allows you to reach the ceiling
in little more than 2 seconds. If you want to practice some of the newly
learned things, I’ve provided a link to a Rocket League Trainer shot in the description. The goal is to clear the ball of the backboard
with only 12 boost. In order to use this you’ll want to
start an exhibition match with no bots. Empty your boost and hit F3 to reset the shot. Alright that’s it for now guys. If you have
any questions or found any mistakes please post them in the comments and leave me suggestions
for what I should test in the future.
