And is that the problem does not come from the fact that I say that the value is equal to itself plus the MotionX? Is he not be a different value before and after the ‘equal’?
No … it isn’t logical ! 
Are you doing anything in scene:hide() that you weren’t doing before?
Or in your collision function?
No no, I don’t change anything …
I noticed something really strange … i put this code to see what happend :
local function movearmadillo (event) if gauche.x == 50 then armadillo.x = armadillo.x + motionx; armadillo.y = armadillo.y + motiony local function stop (event) if event.phase =="ended" then motionx = 0; motiony = 0 end end Runtime:addEventListener("touch", stop ) end end Runtime:addEventListener("enterFrame", movearmadillo)
and like this that work ! But, I star the game, i play once the game, no problem, I go to the GameOver scene, no problem, and here, if I go to the menu that’s good but if I go to playAgain the same message appears … so that’s mean the problem is postponed for a lap …
I put my entire code, I don’t know, if you see something …

Thak you !
That’s very hard to read. You’ll get better and quicker replies if you format things properly.
Have a look here: https://coronalabs.com/blog/2015/06/09/tutorial-the-value-of-well-formatted-code/
You’re using composer, so why not create a gameover scene?
When the collision happens, you’d just need to call composer.gotoScene(“gameover”).
Your gameover scene could then have a button that when tapped uses composer.gotoScene() to go back to the game.
Hi !
I did what you say and thats good, thank you ! But I have an other problem … when i relaunch the playGame scene or the mainMenu scene the physics of my player and the meteor doesn’t dissappear … so when i play for the second time i have 2 players and 4 meteors but only one player and 2 meteor are visible … i noticed this when i write “physics.setDrawMode(“hybrid”)” …
How can I do to destroy these physics or can I relaunch the entire game if I clic on a button as if i start the game for the first time ?
Thank you for your answers !

I’m not sure exactly what the behaviour you’re describing is, but I can make a couple of important points. First of all, when you use composer, every object needs to be inserted into its scene. Have a look at the templatefor a composer scene. Notice that inside each method is the line
local sceneGroup = self.view
You need to use sceneGroup:insert(yourObject) on every object in the scene so that composer will control it properly as you move between different scenes.
Secondly, composer scenes have show and hide methods as you can see in the template. The show method would be a good place to add physics to objects, and the hide method would be a good place to remove the physics.
Hi Hasty,
I’m really sorry but I don’t understand what you said … I think it’s the good thing to resolve my problem but i don’t find the lines code I had to put on my program … it would be very nice if you could give me the code to write, I will find where to place them. If you do that, I would be saved because I have to give the project finish to my profesor in 2 weeks …
I still search but if you do that I will be very happy !
Thank you !

I’d hate to give too much away and get you in trouble with your professor. I’ll show you a small project though, that shows how to properly insert objects into scenes, change between scenes, and use scene:show() and scene:hide() to control what happens in your game:

Also the score is no longer displayed … I really feel like you wasting your time I’m sorry but I really need help!
I think my only problem comes from poor provision of the code, not the code itself …
Moreover, there is no problem with my teacher this is just an option and is professor of computer science, he knew absolutely no corona sdk before I will make him discover.
Thank you again for your help, I will seal my code.

You should read and re-read this tutorial until you get it: https://coronalabs.com/blog/2014/01/21/introducing-the-composer-api-plus-tutorial/.
I’ll summarise here, though.
When you first go to a scene with composer.newScene(), that is the one and only time that scene:create() will be called (unless the scene is destroyed). This is where you should generally create your objects and insert them into sceneGroup.
scene:show() will executed twice whenever you use composer.gotoScene() to go to the scene. It executes first when composer.gotoScene() is called, when the previous scene is still on the screen. It is called a second time when the scene is fully on screen. event.phase will have different values to distinguish between the two: “will” and “did”.
scene:show() will be called twice every time you go to the scene. So this is where you’ll want to reposition objects, reset scores, etc.
scene:hide() is similarly called twice when you leave the scene. The first time is when composer.gotoScene() is called and the scene is still on screen. The second time is when the scene is fully off screen, and has been replaced by the new scene. These are also distinguished by event.phase being either “will” or “did”.
I’m not sure how familiar you are with the concept of scope. If you’re unsure about it, you should read here: https://coronalabs.com/blog/2015/06/16/tutorial-scope-for-beginners/
You might want to create your armadillo, for example, in the scene:create() function, and then reposition it with scene:show() every time the scene restarts. To do this, you can forward-declare your armadillo. All you need to do is put this code:
local armadillo
before the scene:create() function and the scene:show() function. This will keep a spot in memory called armadillo that is in scope for the scene functions. So in scene:create() you just need to create the armadillo with:
armadillo = display.newImage(...)
Then in scene:show(), when you want to put the armadillo back to its starting position (assuming you want to do that), you can just put:
armadillo.x = 160 armadillo.y = 200
You can treat the meteors in a similar manner.
Using a spawn function for your meteors is a perfectly fine thing to do, but using one for each meteor is very redundant. I would suggest you have one spawn function, before scene:create(), something like this:
local spawnMeteor() local meteor = display.newImage("meteor.png") meteor.x, meteor.y = ... metoer.width, meteor.height = ... return meteor end
Inside scene:create() you could then make your meteors:
meteor1 = spawnMeteor() meteor2 = spawnMeteor() sceneGroup:insert(meteor1) sceneGroup:insert(meteor2)
I didn’t use local for the meteors there, so these will be global variables, unless you forward declare them near the top of the file (recommended).
scene:show() would next be a good place to start your meteors moving.
Don’t forget to insert your buttons into the sceneGroup as well, and remember that the order you insert things affects which objects appear on top. This is why you almost always want to insert the background first, so that it will be behind everything else.
Also, you are calling composer.gotoScene() inside of scene:hide(). You never want to do that. composer.gotoScene() is used to change scene. While changing scene, scene:hide() is called on the previous scene, and scene:show() on the next scene you are going to. To put composer.gotoScene() in either function is to try and change scene while you’re in the middle of changing scenes. That’s sure to mess things up, and perhaps result in an unwelcome visit from xZibit.
Hi,
I think I understand a lot of things, thank you ! But I don’t finish because I had some little problems … In my scene:create() when I insert things in the sceneGroup they doesn’t appear on the screen, their physics body are on the screen, i see them whit the hybrid mode but the image is not on the screen.
And my second problem is, I couldn’t go to the scene:hide() … i tried to put the collision function at the end of the scene:show() but the scene hide doesn’t launch …
Then, in my scene hide, can I create a button to relaunch the game and another to go to the menu or did I had to do this in another scene ?
A few small effort and I’ll eventually get there … at least I hope! (I’ll send you half of my mark 
)
-
Did you make sure to insert objects into the scene in the order you want them layered? For example:
sceneGroup:insert(background) sceneGroup:insert(armadillo)
That will place the background down first, with the armadillo then on top of it. But if you do this:
sceneGroup:insert(armadillo) sceneGroup:insert(background)
then the background will be on top of the armadillo and you won’t see it ( the armadillo).
-
The scene:hide() function isn’t launching as you haven’t added the listener like you’ve done for scene:show() and scene:create() on lines 188 and 189. You just need to do the same for scene:hide() also.
-
Don’t create a new button in scene:hide(). Remember that this function is called while changing scenes. It’s just useful for stopping timers and animations, and things like that… a bit of tidying up as you leave the scene. You definitely want to add new buttons in another scene, like in the example I showed you.
As for your collision function, I would create it before the scene:create() function and then either:
- add the listener in scene:create()
- or add the listener in scene:show() and remove it in scene:hide()
All since good but i can’t end my game on collision … I don’t understand how to do this !
Can you help me for the collision function and add the listener in scene:show and how to remove it in scene:hide() ?

Put this inside it to see what’s going wrong:
print(event.object1.myName, event.object2.myName, scoreTimer)I have found the problem but now when the collision occure i couldn’t go to the sceneHide … a special code exist for this ?
Sorry, I think my problem is here :
function endGame (event) if event.onCollision == true then composer.gotoScene("hide") local option = {effect = "fade", time = 200} print("okay !") end end Runtime:addEventListener("enterFrame", endGame)
I think it’s not the good code to enter the collision function on the scene:show(). The print desn’t appear so the function doesn’t work and I don’t know if I have to use “composer.gotoScene” or “local option”. And the Runtime:addEventListener(“enterFrame”, endGame) may be wrong …
There is no onCollision property in the enterfame event table, so event.onCollision will always be nil. An enterFrame event table has no details about collisions, so this is the wrong way to do this. You need a collision listener. You were on the right track before.
