Object 减速物体？

我有一个球体对象从屏幕顶部掉落（球体位置y=5）。我有一个“isTrigger=true”和“Mesh renderer=false”的立方体，位置是“y=0.5”（0.5=立方体的中心）。你看不到立方体

球体正在下降。现在我想，当球体接触立方体时，球体的速度会减慢到零（没有反转）。我想要衰减/阻尼

我尝试了这个例子，但没有成功：

脚本已附加到多维数据集。

您可能希望尝试以下方法：

// We will multiply our sphere velocity by this number with each frame, thus dumping it
public float dampingFactor = 0.98f;
// After our velocity will reach this threshold, we will simply set it to zero and stop damping
public float dampingThreshold = 0.1f;

void OnTriggerEnter(Collider other)
{
    if (other.name == "Sphere")
    {
        // Transfer rigidbody of the sphere to the damping coroutine
        StartCoroutine(DampVelocity(other.rigidbody));
    }
}

IEnumerator DampVelocity(Rigidbody target)
{
    // Disable gravity for the sphere, so it will no longer be accelerated towards the earth, but will retain it's momentum
    target.useGravity = false;

    do
    {
        // Here we are damping (simply multiplying) velocity of the sphere whith each frame, until it reaches our threshold 
        target.velocity *= dampingFactor;
        yield return new WaitForEndOfFrame();
    } while (target.velocity.magnitude > dampingThreshold);

    // Completely stop sphere's momentum
    target.velocity = Vector3.zero;
}

我在这里假设您的球体上有一个刚体，并且它正在下降到“自然”重力（如果没有-只需将刚体组件添加到球体中，无需进一步调整），并且您熟悉协同程序，如果没有-请参阅本手册：

如果使用得当，协同程序会非常有用：）

球体有刚体吗？

// We will multiply our sphere velocity by this number with each frame, thus dumping it
public float dampingFactor = 0.98f;
// After our velocity will reach this threshold, we will simply set it to zero and stop damping
public float dampingThreshold = 0.1f;

void OnTriggerEnter(Collider other)
{
    if (other.name == "Sphere")
    {
        // Transfer rigidbody of the sphere to the damping coroutine
        StartCoroutine(DampVelocity(other.rigidbody));
    }
}

IEnumerator DampVelocity(Rigidbody target)
{
    // Disable gravity for the sphere, so it will no longer be accelerated towards the earth, but will retain it's momentum
    target.useGravity = false;

    do
    {
        // Here we are damping (simply multiplying) velocity of the sphere whith each frame, until it reaches our threshold 
        target.velocity *= dampingFactor;
        yield return new WaitForEndOfFrame();
    } while (target.velocity.magnitude > dampingThreshold);

    // Completely stop sphere's momentum
    target.velocity = Vector3.zero;
}
