This is the wiki page for the console command:
The ball command can provide information about the ball location and rotation. It also allows manipulation of the current location, rotation, velocity, and angular velocity of the ball.
To use the command to get information about the current location and rotation, open the console and type
Location is given in game coordinates (unreal units). Rotation is given in Euler angles 16-bit integers -32768 = -pi to 32767 ≈ pi.
To change the ball location, type
ball location X Y Z
Replace X, Y, and Z with the desired coordinates in game units (unreal units). Unlike the retrieval of the location, this is 100% accurate.
To change the ball rotation, type
ball rotation Pitch Yaw Roll
Replace Pitch, Yaw, and Roll with the desired euler angles scaled in 16-bit integers, -32768 = -pi to 32767 ≈ pi.
To change the ball velocity, type
ball velocity X Y Z
Replace X, Y, and Z with the desired velocity in game units (unreal units / second). 6000 uu/s is the maximum total velocity of the ball.
To change the ball angular velocity, type
ball angularvelocity X Y Z
Replace X, Y, and Z with the desired angular velocity in rad/s. 6 rad/s is the maximum total angular velocity of the ball.
To freeze the ball in place and remove all angular and linear velocity, type
