[sdl2gdx 1.0.4] Window flashes

[alyrow]

Hello, I decided to use sdl2gdx 1.0.4 for my project but when I add a RumbleController or SDL2Controller, my window flashes (disappears next appears next disappears next appears...). But when I retrograde to 1.0.3, this problem disappears.

Can you post a complete copy of your project (or a minimal example) so I can reproduce the problem?

Sure :

        //camera.translate(1,1);

        // set the TiledMapRenderer view based on what the

I need something I can build, including the gradle scripts. Probaby easier if you zip the whole project folder and post the zip file.

[alyrow]

Controller flashing screen.zip Well, you need to run Lwjgl3Launcher

[alyrow]

Ouha that strange I don't have the issue with the .zip

[electronstudio]

When I run it I get no flickering

[alyrow]

Yes it'is strange the zip version works correctly. Well, the problem comes from me... Thanks and sorry for the inconvenience.

[electronstudio]

No worries. If sdl2gdx 1.0.4 is doing something differntly than 1.0.3 even you can work around I would still like to know.

Off topic but a couple of other suggestions. I see you are using LibGDX 1.9.10 with tmx map files. When I did this I got crashes with certain files. I reported it but they didn't seem interested in fixing it. I had to go back to 1.9.9.

Also you might want to try LWJGL2 backend rather than LWJGL3. I'm using 3 because I had a depenency that needed it, but it doesn't seem to have ever been finished to production quality like LWJGL2 was, so if I have problems I switch back.

[alyrow]

OK, I replaced my project by the zip project and now it seems to work correctly. Strange ! Maybe it's due to the config of the project that was not exported in the zip... But now it works !

Oh thank you so much for the advice with tmx map files. If there was a problem i probably wouldn't find the cause because it's the first time I use Tiled.

And for LWJGL2, I just have to uncomment and comment a few lines.

Thanks again for your help !

PS : I think we can close this issue now.
