I did a vivisectionof your code and found a mistake on the paddle's AI, that makes them go back and forth (like if they were shaking).
Not really noticeable, unless you replace the particles with another kind of display (like a rectangle or something).
Currently you've got this:
Code: Select all
if balls[1].live==false and ai1 and ai2 then
for _,b in ipairs(balls) do
b:start()
end
end
if ai1 then
local p = paddles[1]
if p.p.y+30 < balls[1].p.y then
p.p.y = p.p.y + p.spd*dt
elseif p.p.y-30 > balls[1].p.y then
p.p.y = p.p.y - p.spd*dt
end
end
if ai2 then
local p = paddles[2]
if p.p.y < balls[1].p.y then
p.p.y = p.p.y + p.spd*dt
elseif p.p.y > balls[1].p.y then
p.p.y = p.p.y - p.spd*dt
end
end
Code: Select all
if ai2 then
local p = paddles[2]
if p.p.y - 32 > balls[1].p.y then
p.p.y = p.p.y - p.spd*dt
if p.p.y < balls[1].p.y then
p.p.y = balls[1].p.y
end
elseif p.p.y + 32 < balls[1].p.y then
p.p.y = p.p.y + p.spd*dt
if p.p.y > balls[1].p.y then
p.p.y = balls[1].p.y
end
end
end
if ai1 then
local p = paddles[1]
if p.p.y + 32 > balls[1].p.y then
p.p.y = p.p.y - p.spd*dt
if p.p.y < balls[1].p.y then
p.p.y = balls[1].p.y
end
elseif p.p.y - 32 < balls[1].p.y then
p.p.y = p.p.y + p.spd*dt
if p.p.y > balls[1].p.y then
p.p.y = balls[1].p.y
end
end
end
That way, the paddle will move only the distance needed, and not the max distance possible on each update. If i'm not making sense, it's because i'm mucho hungover
but the thing is, that it works better.

You could of course use math.min there.

Entertaining game! Power ups are awesome! Would like to see this on an IPhone or something
Pure prettyness!

I'm trying to understand hmmm....
paddle position = math.min( paddle position + speed , ball position )
will go and try :-p
Ps: you've got to use math.min and math.max (depending on the movement direction)

I meant this:
Code: Select all
p.p.y = p.p.y - p.spd*dt
if p.p.y < balls[1].p.y then
p.p.y = balls[1].p.y
end
could be replaced by:
Code: Select all
p.p.y = math.max(p.p.y-p.spd*dt, balls[1].p.y)
And the other by math.min.

Yes, it does work :-)

Wow. I forgot how awesome this is. And still working without change, even though the last version is from seven months ago.
Also, I had the whole split-balls thing, and they were sorta stuck: they bounced against each other, went to the other side, bounced again, etc. At a certain moment, a third ball appeared.
Also, it appears to lack a license. This makes böb sad:

Böb's quite old, actually. One of the suggested names of LovelyBigPlanet's protagonist, IIRC. We ended up with Neo. We ended up in permanent hibernation, of course.
