Multiplayer racing game

cat555 · 08-13-2014 02:00 PM

Hi, i've installed this game (directly from google play) for some time now... it usually ran Ok, but since the last update (April i think), the game just freezes... the race starts and randomly it freezes and can't play no more...

Unfortunately it doesn't dump any useful information (adb logcat)...

Can it be related somehow with EE3.0?

On some other tests i've been working with Esenthel, i also got some random freezes, but just not so often like in multiplayer racing game.

Any ideas?

By the way, i'm using Nexus 7 device.

Thanks!

Hi,

I've just played the game on my Galaxy Note 2 for 100 seconds in multiplayer mode against my Win laptop, and it had no issues.

Hi, thanks for your reply.

Well, i got the sources from the store, and i can repdroduce the same behavior. The race starts and almost in the first seconds the game freezes. I've tried in debug mode, but there is just a single line in logcat that's related with this freeze...

Can you give me some clue of how to debug this? I've already done the basics by commenting almost all the code by parts to find the part that lead to this issue, but nothing... i just can't find anything...

My android version is 4.4.4 at the moment.

The only debug messages i'm getting from logcat are logged when application is started:

Code:

But this also is shown when every Esenthel application is started, so it's not specific to this game.

Hi,

Since when have you started experiencing these problems?
Perhaps this is related to 4.4.4 Android.

My phone is on 4.3 and there's no update for my device anymore.

Hi,
I don't know exactly when started to happen, but i've done a bunch of tests now and this is happening all the time with this game... i've reproduced this behavior in other projects but the frequency is very low.

But finally i managed to find the cause... this only happens with the default world mode:

Code:

Game.World.mode(Game::WORLD_STREAM);

If i use

Code:

Game.World.mode(Game::WORLD_FULL);

the problem is gone...

The strange here is that i have other projects using WORLD_STREAM, and i don't have this problem happening with such a frequency.

Thanks,

This means that on your device loading assets on a secondary thread may cause issues.

I cannot investigate further without having a similar device to make tests.

cat555 · 08-21-2014 10:19 AM

Yes i understand... it seems to be related with 4.4.4 on this device... i remember that recently i didnt't have this issue.

Let's see the behavior on the next release of android... i'll update that information here when relevant.
