<!-- Format
|
|
It is possible to give relative values (factors and more) for each property.
|
|
|
|
The format as a regex is: ([+-*/](%d+|x))*
|
|
An empty value means no change, a value without sign or with a '-' replaces
|
|
the previous value. If an operator prefixes the string, e.g. *1.5 (- doesn't
|
|
work because it's a sign). x will get replaced by the previous value which
|
|
means *1.5 is equal to x*1.5. It's also possible to combine operations:
|
|
+1.5*20 means "add 1.5 to the previous value and then multiply by 20".
|
|
Note that it's computed sequentially from left to right and there is no
|
|
operator precedence. Also whitespaces aren't allowed because they are used
|
|
to split arrays.
|
|
If you want to return the square of something use x*x or only *x.
|
|
|
|
ATTENTION: '-' is a special case if it is the first character of a number-
|
|
string. It means that the number is negative and NOT that the following
|
|
float will be subtracted from the base value. So if x = 10 and the string
|
|
"-5" is processed, the result will be -5 and not the same as "x-5", which
|
|
would result in 10 - 5 = 5.

contact with the ground (i.e. it then can't steer or accelerate
|
|
anymore).

|
|
are damped to avoid that karts in a collision are too easily pushed

<!-- Turning
|
|
radius: The turn radius of the kart at
|
|
a given speed. The actual steering angle is dependent on the
|
|
wheel base of the kart: radius = wheel_base/sin(steering_angle).
|
|
The values below define that at speed 0 the turn radius is 2, at
|
|
speed 10 the radius is 7.5 etc.
|
|
The actual turn radius is piece-wise linearly interpolated. This
|
|
allows for tighter turning at lower speeds, and also avoids that
|
|
the kart becomes too hard to control at high speed (speeds
|
|
higher than 25 can only be reached with powerups).
|
|
time-full-steer: This is the amount of change in steering depending
|
|
on current steering. So if the steering is between 0 and 0.5,
|
|
the time-for-steering-change is 0.15. If the current steering is
|
|
between 0.5 and 1.0, the time-for-steering-change is 0.25.
|
|
The speed is used as dt/time-for-steering-change.
|
|
In short: steering at less than halfway is somewhat faster,
|
|
which should avoid oversteering (by pressing the key for too long),
|
|
but slower when you want to steer more. Overwall with the current
|
|
settings the expected time-to-full-steer is:
|
|
0.5 * 0.25 + 0.5 * 0.15 = 0.2 ... which is overall the same
|
|
time we had previously. -->

decrease: multiplicative decrease of skidding factor in each frame.
|
|
max: maximum skidding factor = maximum increase of steering angle.
|
|
time-till-max: Time till maximum skidding is reached.
|
|
visual: Additional graphical rotation of kart. The graphical rotation
|
|
of the kart also determines the direction the kart is driving to
|
|
when skidding is stopped.
|
|
visual-time: How long it takes for the visual skid to reach maximum.
|
|
revert-visual-time: how long it takes when stopping a skid to revert
|
|
the visual skid and bring visuals and physics in sync again.
|
|
angular-velocity: Angular velocity to be used for the kart when skidding.
|
|
min-speed: Minimum speed a kart must have before it can skid. Must be

|
|
bonus-force: A speedup applied to the kart whick skidded for a while.

|
|
bonus-force: Additional engine force (this is used to offset the fact

|
that turning after skidding (e.g. to correct direction) often uses

|
up the skid bonus).
|
|
post-skid-rotate-factor: a factor to be used to determine how much

the chassis of a kart should rotate to match the graphical view.

A factor of 1 is identical, a smaller factor will rotate the kart

|
less (which might feel better).

|
[-1,1]) is mapped to [reduce-turn-min, reduce-turn-max] when skidding
|
|
is active (for left turn, right turn will use [-max, -min]). The
|
|
effect is that while you skid (say left) you can adjust the direction

|
of the turn the kart is doing somewhat by steering to the left and right,
|

but you will always keep on doing a left turn, just more or less. -->
