javascript - 索引超出范围异常 : Array index is out of range

Question

我不明白这个错误的原因是什么，有人可以帮助我吗？

IndexOutOfRangeException:数组索引超出范围。
(位于 Assets/Scripts/PlayerCar.js:73)
比较近似(det、1.0F、.005f)
UnityEditor.DockArea:OnGUI()

我的代码:

var GearRatio : float [ ];
var CurrentGear :int= 1;
var EngineTorque:float=230.0;
var MaxEngineRPM:float=3000;
var MinEngineRPM:float=1000;
private var EngineRPM: float = 0.0;

function Start () { 
        rigidbody.centerOfMass += Vector3(0, -1f, 0.25f);
}
function Update () {
        EngineRPM =( FrontLeftWhell.rpm + FrontRightWhell.rpm)/2 * GearRatio[CurrentGear];
        ShiftGears();

        FrontLeftWhell.motorTorque = (EngineTorque /GearRatio[CurrentGear]) * motorInputTouch;
        FrontRightWhell.motorTorque = (EngineTorque /GearRatio[CurrentGear]) *  motorInputTouch;        
}

function ShiftGears(){

        if(EngineRPM>=MaxEngineRPM){
        var AppropriateGear: int =CurrentGear;
        for (var i=0;i<GearRatio.length;i++){
                if(FrontLeftWhell.rpm * GearRatio[i]>MaxEngineRPM){
                    AppropriateGear=i;
                    break;
                }
            }
        CurrentGear=AppropriateGear;
}

if(EngineRPM <=MinEngineRPM){
    AppropriateGear=CurrentGear;
    for (var j=0;j<GearRatio.length;j++){
        if(FrontLeftWhell.rpm * GearRatio[i]>MinEngineRPM){
            AppropriateGear=j;
            break;
        }
    }
   CurrentGear=AppropriateGear;
}

Answer 1

我认为，问题就出在这一行

EngineRPM =( FrontLeftWhell.rpm + FrontRightWhell.rpm)/2 * GearRatio[CurrentGear];

    FrontLeftWhell.motorTorque = (EngineTorque /GearRatio[CurrentGear]) * motorInputTouch;
    FrontRightWhell.motorTorque = (EngineTorque /GearRatio[CurrentGear]) *  motorInputTouch;
