Laggy gameplay and occasional crashes

Do you destroy the old scene?

Yes ofc, but there is a couple of objects (game character, networking script etc.) that stay between scene changes (DontDestroyOnLoad()).

And what happens if you go from scene 2 to scene 1?

It works nicely in scene 1. I'm starting to think it's our network library (Badumna) which causes the lagginess, but I'm still not sure. How should I try to find out if it's Badumna or something of our own code?

Isolate and disable any DonDestroy objects one by one to find out what is causing you the headaches.

There's two DontDestroy-objects that cannot be disabled, our player and the networking script. Disabling either will cause tons of null references 'cause they're referenced in tens of places.

Is there any possibility to play your game without networking?

Nope, it's $$anonymous$$$$anonymous$$O game and everything is built around Badumna. Any single scene can be detached and played without networking, but the problem doesn't occur then. There's lots of stuff going on between Badumna, other networking-related objects, player objects and scenes, and as such I don't think the problem is related to the scene-specific components.

But if you only have problems with 1 --> 2 and not with 2 --> 1, there is some code that is specific for your scene that seems to be leaking, right?

Well, this is the tricky part, I don't know what happens in Badumna in this situation. I've tried disabling every single thing in Scene 2, but the problem persists. It sounds to me that it's really related to the scene change, and it somehow sticks through the whole scene.

$$anonymous$$y gut feeling would be that this is down to Badumna, I'd remove calls to it to try and find whats doing it. Out of interest, your gamecontroller isn't loading a new version of Badumna in the new scene (so doubling up) is it?

@Bleedi: It is good practice to have Unit Tests that will help you test such situations. A game should always be able to run without networking.

Nope. We have about 50-60 scenes, and this only happens in this one scene pair. The only difference with this scene B is that we change the player avatar on the scene change. It has worked nicely before, but it somehow "blew up" yesterday. I haven't been able to find the reason or anything I could've done yesterday to make this happen.

If that is the ONLY difference, check your changelog in SVN and see who made the changes yesterday. Go back to an old revision and check if it is ok there.

The latest version in our depo is working, it's my own working copy that's bugging (won't commit buggy/laggy stuff :p). At the moment I'm going through all the working copies and checking diffs, but so far, there hasn't been anything that could've done it.

1. Did you check your new code on another computer?

2. What happens if you revert your new code to the older one? (Create a new checkout in a new folder)

I didn't try the new code on another computer, but I made stand-alone and web builds and the problem occurs on those too.

I tried creating a checkout with older rev, and it works nicely. It's the newly made code which causes it (somehow), I just can't find anything that could actually cause it. Everything I've checked so far is in line with the old code, the new code just sends some new data to Badumna's networking scripts, in similar fashion as all the old code does. Everything possible is claused between try-catch, and no exceptions are thrown at any given time. Execution runtime snippets give excess values only on Badumna's internal function calls (when I call a function inside the Badumna DLL).

Did you run the web builds on other computers as well?

Try to isolate which part of your code is causing this trouble. It $$anonymous$$UST be in your new code. $$anonymous$$aybe it's the total data traffic in some way.

No, I didn't run the web builds on other computers.

I'll be isolating the code part at a time and try to find what causes the problem. I guess it should be something in the networking code of our own part which handles the scene / avatar changes. I really can't think of anything else.
