-- when moving left
if paddlex >= 0 then
    -- move paddle left
end

-- when moving right
if (paddlex + paddle width) <= 650 thn
    -- move paddle right
end

but make sure you compensate for the width.ect when moving right ( depending on what you are using )[/QUOTE]

This is pretty much what I got, but that doesn't stop the pad from moving 0-5 pixels out of the screen, since it moves more than 1 pixel each update.

[QUOTE=Sc00by22;32894995]Check the position and if it goes above or below the screen size stop it from moving, or above.[/QUOTE]

I'll try that! Thanks.

EDIT: Yeaaas! got it working :-)

[lua]if paddlex < 0 then
paddlex = 0
elseif paddlex + paddlew > love.graphics:getWidth() then
paddlex = love.graphics:getWidth() - (paddlex + paddlew)

this is how I did it

Why would you do ([B]paddlex[/B] + paddlew) in line 4?

Guys how do I collision between two images

box2x > box1x + box1w - 1 or -- Is box2 on the right side of box1?

then

else

I got started on something like this on my calculator in math class last year, but I only worked on it in class and only during the last couple weeks of school. I didn't finish it, but I had the "paddle" and the "ball" working separately; all I needed was to add some "collision detection" and decide how to score it.

[QUOTE=Maurice;32895325]Why would you do ([B]paddlex[/B] + paddlew) in line 4?[/QUOTE]

yeah, good point. Needless to say, I didn't test this.

That should just be love.graphics:getWidth() - paddlew.

How do I assign width and height parameters to my images? And how do I take use of a function like that in my update? I can't even figure out how to do a simple boolean, can't find anything in the wiki

image:getWidth() and image:getHeight() returns what you would expect.

[editline]21st October 2011[/editline]

also the wiki is for LOVE. Not lua. So there's nothing about the actual language.

Oh. Well dangit, then. Tried looking at the link on the first page but the boolean part never stated how to state a boolean, so I don't know. Also image:getWidth()? I have no idea where to put it :smith:

variable = true -- or false

I suggest looking through this love file

Research the source code.

Well there's everything required in here but I don't know what to add :<

But... but... there's no gravity in space! The fundamentals of the game would never work!

(just kidding of course, looks good. Especially if this is a first project)

eh, i started with hello world in c++ but i guess his would do too.

Okay, thanks. Wish it had an example for collision detection though because I still can't get that working

For a breakout game, a rectangle collision isn't a good idea anyway. You could move your paddle all over the place and it'd always hit the ball.
Instead, check if the ball is crossing a Y value at the current update, and if so check if the X value is where the paddle is.

I think I'll participate too, but using C# & SFML instead.

Happy coding everyone :)

[mechanarchy]

I have collision code that mostly works, but if I move the paddle in such a way that the ball collides with the side of it I can get the ball to bounce endlessly [i]inside[/i] the paddle. Is there any easy way of avoiding this or should I just do the cheap hacky way and reset the ball's y-value when it collides?

Got SFX to work again. Fun to work with Love again. Pun intended.

I've just finished mine. I will maybe add some feature because it's really generic.
