Crash when trying to change to gameover scene

Director Class
1

I have no idea what’s causing this. I remember from the youtube tutorial video that you mentioned something about cleaning timers, etc, but when I went into the director.lua to uncomment the cleaner function it was already uncommented, so I guess it’s already cleaning. I’ve got about 10 timers and some more functions and listeners in my game, maybe they’re causing it?

Code looks like this:

-- Die  
function dieFunction()  
 if(score \> bestScore) then  
 bestScore = score  
 saveValue("scorefile.data", bestScore)  
 end  
 director:changeScene("pregame")  
end  
 if(event.phase == "began" and event.other.class == "7") then  
 dieFunction()  
 end

This causes a crash… [import]uid: 14018 topic_id: 5630 reply_id: 305630[/import]

Maybe I should include this

Application Specific Information:
Assertion failed: (IsLocked() == false), function CreateBody, file /Users/ansca/.hudson/jobs/Main-DMG/workspace/platform/mac/…/…/external/Box2D_v2.1.2/Box2D/Box2D/Dynamics/b2World.cpp, line 84. [import]uid: 14018 topic_id: 5630 reply_id: 19245[/import]

It seems to be something at your code, not the changeScene itself. Please take a look at your code or put all the code here. [import]uid: 8556 topic_id: 5630 reply_id: 19258[/import]

What can cause changeScene crashes?? Because I have no idea what to look for at the moment… Everything seems to be working as it should, except when I add the changeScene inside the dieFunction, then it crashes upon collision [import]uid: 14018 topic_id: 5630 reply_id: 19268[/import]

Have you tried to run it with the debugger so you can tell exactly what line it crashes ?

[EDIT] Also, check your file name. I made that error once and everything crashed. I was telling director to load “survivalmode” and it should have loaded “survival-mode” instead. I don’t know if it’s case sensitive too. Just a guess like that. :wink: [import]uid: 1058 topic_id: 5630 reply_id: 19409[/import]

I’ve checked all the names, they’re correct… Thanks, I’ll try it with the debugger as soon as I get home :slight_smile: [import]uid: 14018 topic_id: 5630 reply_id: 19443[/import]

This is what I got from the debugger:
Assertion failed: (IsLocked() == false), function CreateBody, file /Users/ansca/.hudson/jobs/Main-DMG/workspace/platform/mac/…/…/external/Box2D_v2.1.2/Box2D/Box2D/Dynamics/b2World.cpp, line 84.
Program finished

On line 84 I’ve got something irrelevant: “southWall.isSleepingAllowed = false”

I’ve got a ball that can collide with 30 different enemies. I’ve got 30 different if statements that each call the dieFunction upon collision and the dieFunction contains the changeScene… [import]uid: 14018 topic_id: 5630 reply_id: 19478[/import]

It not seems to be a problem with Director, maybe if you talk to Ansca team they could help better. [import]uid: 8556 topic_id: 5630 reply_id: 19642[/import]

Can enterFrame functions make director not able to change scene? Because I don’t remove them upon changing scene… I’ll try e-mail Ansca, thanks! [import]uid: 30185 topic_id: 5630 reply_id: 19656[/import]

enterFrame is very powerful and when it’s added to Runtime, Director can’t remove it. [import]uid: 8556 topic_id: 5630 reply_id: 19808[/import]

I believe the error has to do with the physics not being locked down when you try to modify it.

Assertion failed: (IsLocked() == false), function CreateBody,

For example, maybe the scene is changing but you are trying to set your object’s isSleepAllowed property after the fact?

Just a thought… I’m having a similar problem.
