c# - 对角线速度太快

Question

如何在不限制任何值或使用“.normaized”的情况下保持对角线速度与水平和垂直速度相同。我试图标准化这些值，但我丢失了 1 到 0 之间的操纵杆值。这是我的代码:

void ListenInput()
{
    Vector3 rightDirection = camera.right;
    Vector3 frontDirection = camera.GetForwardFromAngleY();

    move = new Vector2(
        Input.GetAxis("Horizontal"),
        Input.GetAxis("Vertical")
        );

    MoveCharacter(rightDirection * move.x);
    MoveCharacter(frontDirection * move.y);
}

void MoveCharacter(Vector3 velocity)
{
    transform.position += velocity * Time.deltaTime * runningSpeed;
}

Answer 1

在这里，您应该钳制输入 Vector2 的幅度。例如 Vector2.ClampMagnitude()来自 Unity API。这将保持输入非二进制并防止对角线变得大于纯水平/垂直输入。

void ListenInput()
{
    Vector3 rightDirection = camera.right;
    Vector3 frontDirection = camera.GetForwardFromAngleY();

    move = new Vector2(
        Input.GetAxis("Horizontal"),
        Input.GetAxis("Vertical")
        );

    move = Vector2.ClampMagnitude(move, 1f);

    MoveCharacter(rightDirection * move.x);
    MoveCharacter(frontDirection * move.y);
}

void MoveCharacter(Vector3 velocity)
{
    transform.position += velocity * Time.deltaTime * runningSpeed;
}
