unity 使用transform.position 方法停止對角線移動

Question

我在嘗試理解如何阻止我的 Ball 對象在向左或向右滑動時對角移動時遇到了很多麻煩，基本上發生的情況是：我向一個方向滑動一個球，然后球從頂部落下屏幕。 當我滑動球時，它會左右移動，但由於向下移動，它也會略微下降 - 我該如何更改？ 我的游戲是二維的

這是您應該需要的所有代碼

//Variables 
public float ballSpeed = 10; //This will handle our Balls left and Right movement when swiped
public float fallSpeed = 2;  //This will handle the speed at which our ball falls
[HideInInspector]
public bool hitWall = false; //Check if our ball has collided with a wall
public bool moveRight, moveLeft;

public RoundHandler roundHandler;


private void OnEnable()
{
    //Get our Components 
    roundHandler = FindObjectOfType<RoundHandler>();
}

#region functions 

void checkWhereToMove()
{
    if (moveLeft == true)
    {
        transform.position -= transform.right * Time.deltaTime * ballSpeed;

    }

    if (moveRight == true)
    {
        transform.position += transform.right * Time.deltaTime * ballSpeed;

    }
}

public void moveDown() {

    //Set our Fall Speed modified by our Current rounds
    fallSpeed = roundHandler.ballFallSpeed;

    if (hitWall != true) {
        //Check if we arnt moving left or Right so that we can move down
        if (moveLeft == false || moveRight == false)
        {
            //Move our Ball down 
            transform.position -= transform.up * Time.deltaTime * fallSpeed;
            //Get our movement input
            checkWhereToMove();
        }    
    } 
}
#endregion

private void FixedUpdate()
{
    moveDown();
}

Answer 1

1. 測試運動需要檢查兩個方向是否都是錯誤的。

2. checkWhereToMove() 在錯誤的地方。

3. 向下移動后，兩個方向都需要重置為false。

public void moveDown() {
        //Set our Fall Speed modified by our Current rounds
        fallSpeed = roundHandler.ballFallSpeed;

        //Get our movement input
        checkWhereToMove();

        if (hitWall != true) {
            //Check if we arnt moving left or Right so that we can move down

            if (moveLeft == false && moveRight == false) {
                //Move our Ball down
                transform.position -= transform.up * Time.deltaTime * fallSpeed;

                //Reset left and right movement
                moveLeft = false;
                moveRight = false;
            }
        }
    }
