touchEvent bug

Solar2D Daily Builds and Public Releases
#1

Hi,

Sometimes my app crashes when I’m changing scene with Storyboard and Director. It happens both before the scene is changes and after. The app crashes after a touchEvent. This is the device log:

Are you using physics? Can you explain a bit about what is going on immediately before/after the scene change? [import]uid: 52491 topic_id: 19226 reply_id: 74168[/import]

Yes, I’m using physics. The physic starts in createScene() and stops in exitScene(). This is how we handle the physic:

  
function scene:createScene( event )  
-- Start physics  
-- Add display objects  
end  
  
function scene:enterScene( event )  
 storyboard.removeAll()  
end  
  
function scene:exitScene( event )  
 currentLevel:clean() -- remove listeners, timers and stop physic  
 currentLevel:cleanGroups() -- Run removeSelf on all display objects  
end

Thank you for helping:-) [import]uid: 88922 topic_id: 19226 reply_id: 74173[/import]

I’m curious as to whether or not the issue is being caused by physics, it seems to be the main issue with things like this.

When the scene changes are any of your physics objects in a collision? [import]uid: 52491 topic_id: 19226 reply_id: 74310[/import]
