Useful Game Values - RLBot/RLBot GitHub Wiki

If you are making a bot, some of these values are given in FieldInfo. You can find more information on that here.

Rocket League is made in Unreal Engine, which means any dimensions will be in unreal units (uu).

Basic Dimensions

WARNING: Note that the X-axis is left and it is not the normal Cartesian layout. Also, yaw is zero at the positive x-axis and increases clockwise. Trig functions work out as usual because the two reversed conventions cancel each other.

Rotations are represented as YZX-ordered Euler angles.

Note: For scratch divide the values by 32.

Rocket League uses a coordinate system (X, Y, Z), where Z is upwards. Note also that negative Y is towards Blue's goal (team 0).

Floor: 0
Center field: (0, 0)
Side wall: x=±4096
Side wall length: 7936
Back wall: y=±5120
Back wall length: 5888
Ceiling: z=2044
Goal height: z=642.775
Goal center-to-post: 892.755
Goal depth: 880
Corner wall length: 1629.174
The corner planes intersect the axes at ±8064 at a 45 degrees angle

For wall lengths, the curvature at the intersections is ignored.

Boost Pads

Small boost pads:

Hitbox is a cylinder, height of 165uu, radius of 144uu
28 in total.
Gives 12 boost.
Takes 4 seconds to refresh.

Big boost pads:

Hitbox is a cylinder, height of 168uu, radius of 208uu
6 in total.
Gives 100 boost.
Takes 10 seconds to refresh.
The pads with a z-component of 73.0 are the big pads. Mirror these coordinates to get all 6:
- Midfield: (3584, 0)
- Corner: (3072, 4096)

A car picks up a boost pad if the car's center of mass (not hitbox) enters the pad's hitbox. This interaction is different when cars are standing still (see the Rocket Science video on boost pad hitboxes)

The coordinates of the 34 boost pads (in the order that RLBot uses):

Turning
- Turning in Rocket League is very complex and not a lot is known. Hopefully, the numbers below can help you out a bit!
- Turn radius: https://samuelpmish.github.io/notes/RocketLeague/ground_control/#turning. Python implementation:

def turn_radius(v):
    if v == 0:
        return 0
    return 1.0 / curvature(v)

# v is the magnitude of the velocity in the car's forward direction
def curvature(v):
    if 0.0 <= v < 500.0:
        return 0.006900 - 5.84e-6 * v
    if 500.0 <= v < 1000.0:
        return 0.005610 - 3.26e-6 * v
    if 1000.0 <= v < 1500.0:
        return 0.004300 - 1.95e-6 * v
    if 1500.0 <= v < 1750.0:
        return 0.003025 - 1.1e-6 * v
    if 1750.0 <= v < 2500.0:
        return 0.001800 - 4e-7 * v

    return 0.0

No matter if you're accelerating or decelerating, (as the throttle is 1) the car's turn radius and velocity balance out so the car turns 90 degrees in about 0.775 seconds, 180 degrees in 1.55 seconds, and 360 degrees in 3.1 seconds.
Accelerating while turning (starting from a standstill with throttle and steer set to 1)
- While turning with steer set to 1 (or -1), the maximum forwards velocity the car can reach is around 1234. It reaches this after 5 seconds.
- The speed of the car after x time can be estimated with the following equation: 1234 * (1 - e ^ [-{time / 0.74704}])
  
  Example Python implementation:

import math

VMAX = 1234
TAU = 0.74704

def get_speed_from_time_turning(time):
    return VMAX * (1 - math.exp(-(time / TAU)))

def get_turn_time_from_speed(speed):
    speed_adj = -(speed / VMAX - 1)
    return -math.log(speed_adj, math.e) * TAU

Decelerating while turning (starting from the top speed with throttle and steer set to 1)
- While turning with steer set to 1 (or -1), the minimum forward velocity the car can reach is around 1234. It reaches this after 7.5 seconds.
- The speed and time can both be estimated with linear piecewise functions. The blue lines is the real velocity, and the orange line is the velocity that is predicted by the piecewise.
  
  Example Python implementation:

def get_speed_from_time_turning(time):
    if time >= 7.5:
        return 1234

    if time >= 4.5:
        return 1272.889 - 5.185 * time

    if time >= 4:
        return 1380 - 27.5 * time

    if time >= 3.2:
        return 1530 - 65 * time

    if time >= 2.6:
        return 1743.333 - 131.667 * time

    if time >= 1.3:
        return 2247 - 325.384615 * time

    if time >= 0.3:
        return 2344 - 400 * time

    if time >= 0.1:
        return 2323 - 330 * time

    if time > 0:
        return 2300 - 100 * time

    return 2300

def get_time_turning_from_speed(speed):
    if speed <= 1234:
        return 7.5

    if speed <= 1248:
        return 245.4857 - 0.192857 * speed

    if speed <= 1270:
        return 50.18 - 0.03636 * speed

    if speed <= 1322:
        return 23.53846 - 0.01538 * speed

    if speed <= 1401:
        return 13.24 - 0.007595 * speed

    if speed <= 1824:
        return 6.9 - 0.00307 * speed
    
    if speed <= 2224:
        return 5.86 - 0.0025 * speed

    if speed <= 2290:
        return 7.039 - 0.00303 * speed

    if speed <= 2300:
        return 23 - 0.01 * speed

    return 0
