团结：绳子摆动3d字符跳跃开始

Question

我试图在统一中创造一个绳索摆动（像虚拟点一样的笔尖）机械师。但是在第一帧摆动时，我的角色突然跳得很远，然后才继续前进和下摆。

void InitSwing(){
    lineLenght = (transform.position - virtualLinePoint).sqrMagnitude;}

    public void SwingLocomotion()
    {
        Vector3 testPos = transform.position + jMotor.moveDirection *Time.deltaTime;
        float newLenght = (testPos - virtualLinePoint).sqrMagnitude;
        if (newLenght != lineLenght)
        {
            testPos = virtualLinePoint + (testPos - virtualLinePoint).normalized * lineLenght;

        }
        transform.position = testPos;

Answer 1

可能是因为Time.deltaTime在第一帧为0？因此，行jMotor.moveDirection *Time.deltaTime将返回0并且testPos将等于transform.position + 0
