I’m really a newbie at this so can anybody show me in this code lines sample how to put a localGroup:clean

What I’m trying to remove is balloons but they can’t be put in localGroup but in localGroup:clean function.

So can anybody please show me how it looks like having a localGroup:clean function in this code.

Thanks for help :slight_smile: [import]uid: 17058 topic_id: 19491 reply_id: 319491[/import]

I’ve got the problem

I think you have already fixed it but for reference:

function localGroup:clean()
localGroup:removeSelf()
localGroup = nil
end [import]uid: 79135 topic_id: 19491 reply_id: 75884[/import]

@andrewscott thanks for the help yeah I’ve got the problem solved

Also if you don’t mind to look at my forum for Making Side Scrolling games [import]uid: 17058 topic_id: 19491 reply_id: 75889[/import]

You shouldn’t need to put localGroup:removeSelf() in localGroup:clean() since director is going to remove that group itself. The types of things you need to put in there are:

removing event listeners
canceling timers
removing display objects that are not in localGroup.
any game logic that needs to happen when the level closes.

@robmiracle thanks for the help also and suggestions. Also if you don’t mind to look at one of my forums that this

I’m wondering what is the best way to have platforms move

I’m not that good at platformers. Not sure how much help I can be. Look up some of the “Camera” items in the Community source. (Not camera as taking pictures, but camera as in the view the player has to the scene)

@robmiracle the forum I’m saying is I have a 2 moving platforms that are not physics. When you see the platform are moving.

If you see in the forum I posted a plug and play code that shows you what I mean.

But If you can’t help I thank you that at least you tried [import]uid: 17058 topic_id: 19491 reply_id: 75912[/import]
