vehdata.lua

The vehdata.lua is the file responsible for storing all C.H.A.S.E.R vehicle profiles

In order to create a tire profile, inside the vehicledata key, fill the tire profile in this manner: (P.S: Like mentioned, the keyname has to be the same names as the yft, so "nero.yft" becomes "nero")

}

iselectric:

Is vehicle electric?

ismotorcycle:

Is vehicle a bike?

dragcoeff:

Usually estimated cd (drag coefficient) cars usually are between 0.15 to 0.4 bikes are between 0.5 and 1.0

basegacc:

The amount of acceleration in G's that will be exerced into the first gear, refer to the math help section for learning how to calculate an estimative.

When setting up a electric car, consider the value x 5, so to setup a gas car value of 1.0 you’d need to input a value of ~0.2

torqueCurve:

RPM in rotations per minute, Torque in Newton Meters, fill like this: {rpm = 1000.0, torque = 687.5},

canuselaunchcontrol:

Can this vehicle use launch control?

launchcontrolrpm:

At what RPM should this vehicle use launch control?

hasstockflywheel:

Should the car have rpm decayment by default?

flywheelweight:

Time in seconds to rpm decayment

hasstockdifferential:

Should the car have differentials by default?

(If disabled, the car will not drift.)

frontdifflock:

Legacy feature, the value here doesn't matter.

reardifflock:

Legacy feature, the value here doesn't matter.

transmissiontype:

What sort of transmission the car has. Valid Inputs:

"automatic"

"sequential"

"manual"

gearratios:

A Table containing the gear ratios.

{-2.25, 2.25, 1.61, 1.19, 0.92, 0.75, 0.62, 0.55, 0.5, 0.5} Always add one extra gear ratio to account for transmission upgrade, once that's done fill the rest with 0.5, the limit is always 10 (1st index being reverse) + 9 gears, do not go over it.

finaldrive:

Simulated final drive to reach the desired topspeed on the last gear, learn how to calculate it here.

automaticshiftpoint:

The point where it should shift in percentage, from 1.0 to 0.0,

thus 0.10 = shift at 90% of the rev range. (0.90 RPM)

weight:

The vehicle weight in KG.

turbodata:

Leave all at 0 if N/A, if using a supercharger, only set the compressorsize, and leave everything else at 0 You can learn to generate a turbo curve and values at this section: Valid Boost ID's: 0 = Turbo 1 = Supercharger 3 = N/A / Disabled

Utilizing the turbo viewer tool

gearboxammount:

Amount of gears the vehicle has

topspeed:

Estimated max vehicle speed in KM/H

tyremodel:

The tyre model the car should used, tyre models are defined in tiredata.lua

If set to nil, peak grip will load from handling.meta.

brakecapacity:

The braking capacity defined in %, as braking can only go as much as the grip goes, so 100% = all breaking the amount of grip can handle, and so on.

If set to nil, will load from handling.meta.

brakedistribution:

Braking distribution in relation to the front wheels, in %, same as the power distribution, but usually you want it slightly more at the front (EX: 55%)

If set to nil, will load from handling.meta.

lstractionlossmulti:

The traction loss multiplier, basically how the tire loses traction in regards to terrain like dirt, sand, etc The higher it is, the worse the off-road performance.

If set to nil, will load from handling.meta.

tracitionlossmulti:

The traction loss multiplier, basically how the tire loses traction in regards to terrain like dirt, sand, etc The higher it is, the worse the off-road performance.

If set to nil, will load from handling.meta.

arbstrenght:

Anti roll bar strength, 0 to 100 %, the more, the more stiffer and less body roll

If set to nil, will load from handling.meta.

arbbiasfront:

Anti roll bar distribution, in %, 100 = only front has a ARB, 0 = Only rear has a ARB, anything in between will distribute the arb force in relation to the front wheels.

If set to nil, will load from handling.meta.

suspensionraise:

Doesn't do anything, currently disabled.

If set to nil, will load from handling.meta.

suspensionforce:

Suspension force, like the handling.meta, no units specified, so you'll need to tweak by feeling.

If set to nil, will load from handling.meta.

suspensionrebounddamping:

Suspension rebound force, like the handling.meta, no units specified, so you'll need to tweak by feeling.

If set to nil, will load from handling.meta.

suspensioncompressiondamping:

Suspension compression force, like the handling.meta, no units specified, so you'll need to tweak by feeling.

If set to nil, will load from handling.meta.
