Segmentation fault @ line 480

Compiling with and without debug flags:

Not trying to bring you down with these bugs, just trying to make the software better. :)

Looking at the source now and looking at some of the compiler warnings.

[Michael Rawson (michael.rawson)]

Well, I've fixed some of the compiler warnings, I'll push those.

The problem with the segmentation fault is that mpos.X at least, equates to NULL. Somehow node->getAbsolutePosition() is failing.

odd...

I'm here for a few minutes on irc, freenode.net as skulltip in #ubuntu..

Awesome. I'm on it.

[eross (drarem)]

the gameloop is within the same class, perhaps on the first pass (class
constructor) it sees a NULL value?

[Michael Rawson (michael.rawson)]

Perhaps. But the offending function is only used within the gameloop and the variable seems to be instantiated. IDK.

[Michael Rawson (michael.rawson)]

Works fine now. :)

[eross (drarem)]

Hmm.. what changed?

[Michael Rawson (michael.rawson)]

I have absolutely no clue. I suggest you look at the diff for rev no. 10...

[Michael Rawson (michael.rawson)]

Btw, I'm starting work on the actual game, so far, I've got a gameloop class that starts the game, and a media class which makes all of the files available after loading them once.

[eross (drarem)]

Ok.. I did comment out the assert which may be why you're not exiting now.

[Michael Rawson (michael.rawson)]

Nah, I put that in to see if it was null or not. Seems to be fixed now, whatever it was. :)
