Hello im coding a pong game with a twist im trying to make it when the player holds the spacebar the bar holds the ball but im having trouble making the ball stop. thanks in advance

```auto

  if ( xpos <= 30+size/2) {
    if (ypos > playerpos1-50 && ypos < playerpos1+50) {

In an event of collision (plus space bar) set a flag attachedToPaddle

If this is true, don’t add speed to ball

**Remark**

You can also use another flag to monitor if the space bar is down (spaceBarDown)

set it to true in keyPressed and to false in keyReleased

I think here you can set the global variable attachedToPaddle to true

</div>

so i create a boolean for attachedtopaddle and then a void() for attachment and then if(xspeed \*= 1) true?

ok i gave it a try, its holding but the ball keeps blinking and it keeps giving points to the left paddle  
` void hold(){  
xspeed = playerpos1;

```
}

```

if (ypos \> height-size/2 || ypos \< 0+size/2) {  
yspeed \*= -1;  
hold = true;  
}`

</div>

first of all, when you want to make the paddle glue the ball when the space bar is pressed once, you need

```auto
  if (key == ' ') {
    hold = ! hold;
  }

```

so hold gets false again eventually.

> so i create a boolean for attachedtopaddle

Yes, for each paddle? So attachedtopaddle1 and attachedtopaddle2.

> then a void() for attachment and then if(xspeed \*= 1) true?

NO.

What you want to achieve is that the ball doesn’t go on (bounces) but stays put on the paddle.

so start of draw()

```auto
void draw()
{
  background(277);

  if (hold && attachedToPaddle)
  {
    // ignore
  } else 
  {
    xspeed *= 1.001;

    xpos += xspeed;
    ypos += yspeed;
  }

```

AND the reflection (only left paddle)

```auto

  if ( xpos <= 30+size/2) {
    if (ypos > playerpos1-50 && ypos < playerpos1+50) {
      if ( ! (hold && attachedToPaddle)) {
        xspeed *= -1;
        yspeed += (ypos-playerpos1)/5;
      }
      attachedToPaddle=true;
    }
  } else {
    attachedToPaddle=false;
  }

```

**Remark**

“tela” is “screen” in portugese. You have this in draw().

It’s like state of a program, mostly referred to as _state_ in the forum

You are doing it wrong.

That’s the core idea of states:

```auto

  switch (tela) {
  case "MENU":
    menu();
    break;
  case "TUTORIAL":
    tutorial();
    break;
  }

```

You should have a state “GAME” as well and put your other draw() stuff into it

Then you can have a proper menu and game over screen

</div>

and your hold() function should be killed

in my way of doing this, the advantage is  
that when player hits space bar again, the ball  
starts again with the old direction (that is stored in xspeed,  
so we want to keep the data. Instead we have this if-check

```auto
if (hold && attachedToPaddle)

```

at the beginning of draw())

Chrisir

**This is the hold function**

```auto
void hold() {
  if (hold) {
    if (xpos == playerpos1) {
       xspeed = 0;
    }
  }
}

```

ok i tried it out and it holds but the ball keeps teleporting past the paddle.

Obviously kill this before the if-clause at the beginning of draw ()

It’s not allowed to execute when the if-clause is false

I had this in my post as well…

Anyway- when the ball is attached and you use wasd you might want to use the paddle together with the ball

The idea is set you click space bar briefly

Then the ball is attached

Click space bar again briefly - ball starts again
