Hello everybody,
First, I’m very new to this, corona and programming. So most of you will probably think my code is crazy and bloated. (this is my first real code)
I managed to get all the below code working without crashing, I’m already happy I managed to do this, with the help of some snippets for the swiping.
this is the first scene, all scenes are the same with different assets (children’s book)
Now, I was testing everything, and i found the transition between scenes slow, it’s logical because it has to do a lot of stuff before the transition starts.
Then I saw I could preload a scene, great, this will make things more snappy.
so I tried to implement loadScene.
But, I can’t get it running
I tried a lot of different options, but to no avail.
the weird thing is, all the storyboard functions like storyboard.gotoScene turn blue in textmate.
storyboard.loadScene does not.
So, is it just not working?
and if it works, where in my code do I implement it and how?
Any other tips to improve my code are very welcome.
Thanks in advance
Tom

– END OF YOUR IMPLEMENTATION
– “createScene” event is dispatched if scene’s view does not exist
scene:addEventListener( “createScene”, scene )
– “enterScene” event is dispatched whenever scene transition has finished
scene:addEventListener( “enterScene”, scene )
– “exitScene” event is dispatched before next scene’s transition begins
scene:addEventListener( “exitScene”, scene )
– “destroyScene” event is dispatched before view is unloaded, which can be
– automatically unloaded in low memory situations, or explicitly via a call to
– storyboard.purgeScene() or storyboard.removeScene().
scene:addEventListener( “destroyScene”, scene )
