Hi everyone, I need some help (again).
My game is almost finished, all I need is one more script information.
I'm making a breakout style game and when my ball gets out of vision, I made it come back on the paddle with this script:

x = paddleleft.x;
y = 27;
xvelocity=0;
yvelocity=0;

Everything works just fine, but what I'd like is that the ball fololows the paddle when it's brought back on it and till mouse button is pressed.

I've searched the forum, watched every demos I could find relative to the subject but i didn't find anything like this.

Anyone has an idea?

You wouldn't really find the answer by searching this case specifically, though I do remember answering this before. Searching for what you are trying to do, have the ball follow the paddle, would probably work better.

You can either change the ball's parent to the paddle after setting the xy values, or use a variable to determine if the ball should move with the paddle. If you don't already have a variable like that, I'd suggest using the parent method. Just make sure to change the parent back to none when you launch the ball.

Yeah I know you answered this before, but I don't understand the ball state thing you talked about then.
I tried to use parent but the ball acts weirdly, it's not brought back on the paddle but at it's left and beside of it.
My paddle is made of four pieces , three of them are child of the first one, maybe that's the problem.
Even when I change the parent to another paddle piece, the ball re-appears elsewhere.

In fact, at the beggining of the game, the ball is child of the paddle, and when it's launched, it's parent is changed to none.
But it doesn't want to be changed back.

You might get positioning problems if you change the parent before repositioning the ball. If you do, then you should use these values.

Code: Select all

x=0;
y=--height/2-parent.height/2;
// this should position the ball right above the paddle

When something is parented to another actor it's (0,0) becomes the parent's xy coordinates. So if you change the parent before setting the xy, you'd have to set the xy values according to that, instead of the normal absolute coordinates.

For the state, it was just a variable telling the actor that it should be following the paddle. state would have two possible values, 0 which means follow the paddle, and 1 which means normal play. When you want it to follow the paddle, set state equal to zero, and when you launch it set it to one. That way in the ball's draw script, you can use this.

Code: Select all

switch(state)
{
    case 0: // follow paddle
    x=paddle.x;
    y=paddle.y-paddle.height/2-height/2;
    break;

    case 1: // ball bouncing
    // any code you might use to monitor the ball
    // what you had in draw before implementing this
    break;
}

If you want I can make a small ged demo of it.

Thanks a lot, will try it today

It worked, it's so cool, thanks a lot. I had to change the y value cause the ball wasredirected in the center of the paddle and still moving, but now all is good.

Just one more question, I have an animation playing when the ball is colliding with the bricks or the wall, everything works fine. But I wonder how could I play another animation just after the previous (the colliding one) is finished ? It's not really important but it could make a real good effect.

But once again thanks a lot, you don't imagine how much pain it was to have the ball out of the paddle.

there is an event called animation finished or something
this must help..
