Pong Source Code | GameDev.net

So here is my Pong Source Code. This is everything that is making the ball move back and forth and bounce off of the paddles. Im noticing that the code is a little backwards(Theres a better way to doing it). Can someone tell me what im doing wrong. Im not really understanding the Sphere and plane collision thing, and all the code i have isnt in VC++ so i dont know how to convert many function to C++, so i have to do it this way until then. The only thing that isnt happening that i need is that the ball doesnt reflect off the paddles like it should realisticly. You cant shoot the ball in a way you normally would in pong, and its pissing me off!! Any suggestions please? It looks like i have to rewrite the code!!!


int moveBall()
{
	
	MinPaddleY = PaddleY - 1.5f;
	MaxPaddleY = PaddleY + 1.5f;

	MinPaddleY2 = PaddleY2 - 1.5f;
    MaxPaddleY2 = PaddleY2 + 1.5f;

	Dist = (BallX - PaddleX) - 1.0f;
	Dist2 = (BallX - PaddleX2);

	if (Dist < -1.5 && BallY > MinPaddleY && BallY < MaxPaddleY  && BallX > -5.0)
	{
		blnBallX = true;
	}
	
	if (Dist2 > -1.5f && BallY > MinPaddleY2 && BallY < MaxPaddleY2 && BallX < 5.0)
	{
		blnBallX = false;
	}
	

	if (BallX < -7.0f)
	{
		++Player2Score;
		Player2Score = (Player2Score + 1.0f) - 1.0f;
		blnBallX = true;		
	}

	if (BallX > 7.0f)
	{
		++PlayerScore;
		PlayerScore = (PlayerScore + 1.0f) - 1.0f;
		blnBallX = false;				
	}

	if (blnBallX == true)
	{	
		BallVX = cosf(BallAng) * 0.2f / 8;
		BallX +=  BallVX;
		--Xrot;
	}
	
	if (blnBallX == false)
	{
		BallVX = cosf(BallAng) * 0.2f / 8;
		BallX -=  BallVX;
		++Xrot;
	}
	

	if (BallX > 4.0)
	{
		if (PaddleY2 < BallY)// && PaddleY2 != BallY)
		{
			PaddleY2 += 0.09f ;
		}

		if (PaddleY2 > BallY)// && PaddleY2 != BallY)
		{
			PaddleY2 -= 0.02f ;
		}
	}

	
	if (BallY < -3.8f)
	{
		blnBallY = true;
	}
	
	if (BallY > 3.8f)
	{
		blnBallY = false;
	}

	if (blnBallY == true)
	{
		BallVY = cosf(BallAng) * 0.2f / 8;
		BallY += BallVY;		
	}
	
	if (blnBallY == false)
	{
		BallVY = cosf(BallAng) * 0.2f / 8;
		BallY -= BallVY;

	}
	
	

return 0;
