Sorry about the format, Forums Did it.
I will try to repost
I’ve edited the original post to format the code. Please read the FAQ for formatting tips.
Thx 
Hi @Codenoob,
Split off the classes and stripped out duplication on your code. Main code given below. Don’t need to keep redefining text characteristics etc. Also, your text is black against a black background (as you load your background image from your DropBox - which we can’t access - when you post put an image in which is in the sprite packs).
After all that couldn’t get the paddle to capture the falling objects.

P.s. anyone know how to colour code these listings?
.@Bri_G You can colour code the listing by encapsulating the code using pre lang = “lua” tag instead of the three ~.
For example:
function checkGrav()
if pos.x >= 0 and pos.x <= WIDTH - size.x then
if Gravity.x > 0 then
pos.x = pos.x + (20 * Gravity.x)
end
if Gravity.x < 0 then
pos.x = pos.x - (-20 * Gravity.x)
end
end
if pos.x < 0 then
pos.x = 0
end
if pos.x > WIDTH - size.x then
pos.x = WIDTH - size.x
end
end

Hi @Reefwing,
function thankYou()

Print("Thanks Reefwing!!!")
end
end
```
Just a test, didn't work on the preview but will post anyway. looked at the HTML source but can't see why this shouldn't format OK. Looked at the source and the browser is putting HTML friendly tags in for the < and > symbols. What's the trick?

Hi @CodeaNoob I also got rid of duplicate code you didn’t need. I also changed some of your sprites because we don’t have access to any sprites you have in your Documents or Dropbox. I also added code to detect when one of the falling objects collides with the paddle. See Paddle:collide() and the if statement I added in randomObjectGenerate(). You will have to modify Paddle:collide() to account for the width of the paddle and the widths of the different objects falling. I gave it some widths and heights just to give you a starting point.

Hi @dave1707,
That’s saved me some time. I intended looking further but was distracted by my lack of ability to fancy format code!!!
Thanks for that.
Bri_G
Hi All,
Looks like the lua formatting works but not immediately. It also looks like @QuantumTroll has a handle on this using CSS.
Bri_G
dave1707,
Thank You! I’ve been needing that collision help!
But is there any way to just take away 1 life for 1 collision instead of every second?
Any help is appreciated.
-CodeaNoob
I’m not sure how you were going to do your scoring, but a suggestion would be to start the game with maybe 10 or 20 lives and subtract a life every time the paddle is hit. When you don’t have any lives left, the game is over and the elapsed time is your score. The more objects you avoid, the higher the elapsed time. In the if statement I added in randomObjectGenerate(), just subtract 1 from Lives and check for 0. Once 0, set a flag to perform some sort of end of game function.
dave1707,
I did that, except every second the paddle is colliding, a life is taken away, so every object is a life loss of around 3.
Thanks,
CodeaNoob
I made too many changes to just show them so it was easier to just send the whole thing. I set Lives to 10, fixed the score to show (ElapsedTime - start). I subtract 1 from Lives each time the paddle is hit, and when Lives reaches 0, I set state to GAME_OVER and display the score on your startup screen where you can start the next game.

U r the bestest!
I am having a Highscore bug, can anyone add Highscores successfully here? I’m sorry for all the demands, but I am a Noob to Codea, Hence my name 
. @CodeaNoob Add the function showHighScore() anywhere in your code and add the line of code showHighScore() in the draw function in the if state==GAME_OVER section. See below for example.
-- find this if statement in the draw function.
if state==GAME_OVER then
fill(255)
text("Score: "..string.format("%.1f",score),WIDTH/2,400)
showHighScore() ------- add this line to your code
end
drawPaddle()
-- add this function anywhere in your code
function showHighScore()
pushStyle()
fill(255)
fontSize(40)
font("Courier")
hs=score
for x=1,10 do
str=string.format("TiltIsland%02d",x)
sc=readLocalData(str)
if sc==nil then
saveLocalData(str,0)
if hs>0 then
saveLocalData(str,hs)
hs=0
end
elseif hs==tonumber(sc) then
break
elseif hs>tonumber(sc) then
saveLocalData(str,hs)
hs=tonumber(sc)
end
end
for x=1,10 do
str=string.format("TiltIsland%02d",x)
sc=readLocalData(str)
str=string.format("%2d) %5.1f",x,sc)
text(str,WIDTH-200,500-x*40)
end
popStyle()
end
Ah, See I tried to add Bit Invader style of Highscores, and that didn’t work. Thx again for all your help:)
