如何增加分数并将其打印在控制台中？

Question

I'm still trying to finish off my very simple game but I've ran into another problem. I want the Console to print (" Player's score ") everytime the ball touches the sidewalls. So i created a new script and called it ScoreManager that should take care of this function. But the only thing the console does is print (0). this is the code.

void Update()
{
    //boundaries 
    if (Ball.transform.position.x < -5.61f)
    {
        RightScore++;
        print(RightScore);
    }

    if (Ball.transform.position.x > 5.5f)
    {
        LeftScore++;
        print(LeftScore);
    }
            
}

RightScore and LeftScore are not defined. If you define them, it should work:

private int RightScore = 0;
private int LeftScore = 0;

void Update()
{
    //boundaries 
    if (Ball.transform.position.x < -5.61f)
    {
        RightScore++;
        print(RightScore);
    }

    if (Ball.transform.position.x > 5.5f)
    {
        LeftScore++;
        print(LeftScore);
    }
            
}
