Unloading levels on change?

Getting Started Newbie Questions
#1

Ok, I use this director thing to change levels (scenes).

I have different problems with it.

  1. I made a level and I copied it, so I have two levels. The first time everything works fine. Then I go to level2 (which is actually the same level in a separate lua file).

From the second level I come to the first level again and so on in an endless loop.

The more I change the levels, the more the level acts crazy.
My moving objects suddenly jump around on the y axis and move between different y coordinates, than I gave them.

  1. If I use a loading screen between levels, then if I go to level2 after the loading screen my background doesn’t load. To be honest nothing loads, except the animations, which are not inserted into the localGroup. On the screen I see only the loading screen and 4 animated images.

So I think, I should have unloaded everything by changing the scene, but appearantly it doesn’t happen.

Can somebody explain, how Corona/LUA handle this? How do I have to organize my levels?

I can’t find anything on it in a comprehensive way.

I don’t really understand these groups and tables and so…

Please can somebody explain it? [import]uid: 6587 topic_id: 5752 reply_id: 305752[/import]

Have you unloaded the Object in the old scene before you create it again in the new scene?

object:removeSelf()

No.

I have 5 such “enemies”:

[code]ghost1 = display.newImage (“images/ghost.png” ,102, 64);
ghost1.y = 64
localGroup:insert(ghost1)

function goUp1 ()
transition.to( ghost1, { time=1500, y=(ghost1.y - 128), onComplete=goDown1 } )
end

function goDown1 ()
transition.to( ghost1, { time=1500, y=(ghost1.y + 128), onComplete=goUp1 } )
end

goDown1()[/code]

They patrol between two points.
They go crazy with time.

Do I have to unload them?
I thought Director unloads everything by making a newGroup on every scene.

How do I unload them?
I assume that I have to put them into an event to be able to use the removeSelf function.

I downloaded the Ghosts vs Monsters game and there I don’t see objects removed by removeSelf.

The whole thing is very confusing for me…

Have you made them local?

for example

  
local ghost1 = display.newImage ("images/ghost.png" ,102, 64);

They have to be local otherwise they can’t be removed by director [import]uid: 10657 topic_id: 5752 reply_id: 19723[/import]

Oh, frack!

Nope…
Thanks!
I will make them local and see, what happens. [import]uid: 6587 topic_id: 5752 reply_id: 19746[/import]

No, making them local does nothing.

They behave the same strange way after the second scene change.

I think, I give up.
This whole thing is totally illogical… [import]uid: 6587 topic_id: 5752 reply_id: 19755[/import]
