---***ATENÇÃO, SE FOR RECARREGAR O SCRIPT IN GAME, CERTIFIQUE-SE DE ESTAR COM O VEICULO TOTALMENTE PARADO OU FORA DE UM VEICULO***----

local airDensity = 1.225 -- kg/m^3 densidade do ar, quanto maior, mais downforce o carro ira ter (ou mais sustentação positiva dependendo do carro), realisticamente o veiculo iria ter mais drag também (resistencia do ar), mas esse script não se mete nessa parte. Alterações nesse valor só terão efeito se deixar a opção logo abaixo em false.
local calculateAirDensity = true --- ative para calcular automaticamente a densidade do ar para uma determinada altura.
local loadSensitivityMultiplier = 1.0  -- deixe em 1.0 para ativar a sensibilidade a carga, 0 para desativar.
local dwMult = 1.0  -- irá multiplicar os efeitos aerodinâmicos, 2.0 para dobra-los, 0 para desativa-los. (ao dobrar, estara dobrando efeitos negativos caso o carro tenha "downforce negativa")

local mode = 3   ---- 1 = aumenta apenas o tractionMultiplier; 2 = aumenta apenas o tractionLoss; 3 = distribui o aumento entre ambos
local improveBrakes = false --- deixe em true caso queira que a desaceleração dos freios aumente. *Esse efeito não é exatamente realista, pois a força dos freios não é afetada pela downforce do veiculo*


local drawInfos = false --- coloque false se não quiser mostrar nenhuma das informações abaixo.
local drawName = true --- coloque false se não quiser o nome do carro.
local xName = 70 	--- posição horizontal do nome do carro
local yName = 500	--- posição vertical do nome do carro
local drawDownforce = true   --- coloque false se não quiser o indicador de downforce do carro.
local xDownforce = 70	-- posição horizontal do indicador de downforce.
local yDownforce = 515	-- posição vertical do indicador de downforce.
local drawGrip = true  ---	coloque false se não quiser o indicador de grip relativo do carro.
local xGrip = 70	-- posição horizontal do indicador de grip relativo.
local yGrip = 530	-- posição vertical do indicador de grip relativo.
local drawTractionMult = true  ---	coloque false se não quiser o indicador do multiplo de tração.
local xTractionM = 70	-- posição horizontal do indicador do multiplo de tração.
local yTractionM = 545	-- posição vertical do indicador de do multiplo de tração.
local drawTractionLoss = true  ---	coloque false se não quiser o indicador do tractionLoss.
local xTractionL = 70	-- posição horizontal do indicador do tractionLoss.
local yTractionL = 560	-- posição vertical do indicador de do tractionLoss.


--[[atributos dos veiculos do jogo, deixe o index da tabela sempre com o id do veiculo em questão
name = nome do veiculos, apenas por praticidade

effectiveArea = area efetiva que irá gerar downforce, caso seja negativa irá gerar o contrário, ou seja o veiculo irá perder aderencia em altas velocidades.
effectiveArea = coeficiente de downforce * area frontal do veiculos.

*a downforce também pode ser chamada de sustentação negativa, veiculos mais pesados são menos sensiveis ao aumento ou diminuição de downforce*

loadSensitivity = sensibilidade dos pneus ao aumento de downforce no veiculo, a medida em que o peso nos pneus aumenta, o grip base dele diminui;
saiba mais aqui : https://en.wikipedia.org/wiki/Tire_load_sensitivity
*Não deixe um valor muito alto, é extremamente sensivel, deixe entre 0 e 0.1.

***A sensibilidade a carga dos pneus não é calculada de maneira exatamente realista, apenas uma aproximação grotesca (quase um chute)
**Vale lembrar que esse script apenas multiplica valores da handling do carro, portanto o efeito final irá depender também do arquivo handling.dat do seu jogo**
