OnCollisionEnter 不起作用：更改车轮碰撞器的侧向摩擦刚度

Question

我试图更改组件中的值，但它不起作用，这是我的代码：

我尝试初始化方法外部的变量，但它给了我一个错误，因为我首先初始化了车轮碰撞器（FDW，FPW，BDW，BPW）

 private void Slip()

{

    //FPW, FDW, BPW, and BDW are all wheel colliders

    float stiffness1 = FPW.sidewaysFriction.stiffness;

    float stiffness2 = FDW.sidewaysFriction.stiffness;

    float stiffness3 = BPW.sidewaysFriction.stiffness;

    float stiffness4 = BDW.sidewaysFriction.stiffness;

    stiffness1 = 5;

    stiffness2 = 5;

    stiffness3 = 5;

    stiffness4 = 5;

}

private void OnCollisionEnter()

{

    Slip();

}

Answer 1

WheelFrictionCurve是一个结构体，所以如果你想改变它的属性，你需要：var curve = FPW.sidewaysFriction;curve.stiffness = 5;FPW.sidewaysFriction = curve;
