Thread: Pong game - Collision detection

Alright so I got

if ( x >= 1PX + 25 ) - Not sure what else to put.

That means I have to change the

g.setPaint( Color.black );
g.fillRect( p1X, p1Y, 25, 60);

values?

Still can't get around how to collide with the ball and paddle.

I've changed the rect to
g.setPaint( Color.black );
g.fillRect( p1X, p1Y, p1Width, p1Height);
Not sure how the format for the if statement goes, because the paddle moves.

Well I know it has to hit the right side of the left paddle.
This would require p1X + p1Width since that would equate to the top right side of it.
Do I have to also include the pPU? Since it is moving......I'm so confused

Then the y value would be
p1Y + p1Height

Would I need to write seperate things for the x and y values? Or could they be incased in the same ()?

So the code should look something like

if ( x >= p1X+p1Width+HALF_BALL_SIZE ) x_inc = -1*S;
if ( y >= p1Y+p1Height+p1Width+HALF_BALL_SIZE ) y_inc = -1*S;
if ( y >= p1Y+HALF_BALL_SIZE ) y_inc = -1*S;

But if the ball hits the top if stays up there, and the border is locked at the width so its stuck in a small rectangle box.

I'm trying to make it so when the ball hits the paddle, it bounces off it. I read about the intersect code but I'm not sure how that works.

So the whole of the paddle should make it bounce back.
So if the ball hit between the top right to the bottom right of the paddle, it will bounce off.

How would I go about coding it?

No clue on how to use that. My knowledge of java programming is very low.

It was just a code I found that created a paddle.
Oh well, guess I'll send the code like this, only have two hours left before submitting time.

Guess its closed.

Thanks for the help Norm.

Even though I didn't get anything accomplished.

Yeah I'm slacked a bit.

But I solved it

{
             if ( x <= p1X+p1Width && x >=p1X)
      if (y >=p1Y && y <= p1Y+p1Height ) {
      x_inc = 1*S;
      y_inc = 1*S;
   }
}

Just figuring out how to make it turn direction on how it hits the box.

Because whenever it hits the paddle box, it goes down every time. I'm wondering if theres a way that the ball hits the paddle makes it go up or down. But if it requires a bit more work I guess I'll leave it.
