Big issues with dock systems

[tdelc]

Hi,

Sorry once again for a new issue, i have applied all your docks and drones branch and your navigation branch. Now I have a huge problem : if a create a drone from a cargo, when i fastly scroll down in the relay screen, the game crash.

I test it a lot, i think it is only when there is a drone in the scenario. And even with the debug mode, i cannot find where the code fail.

If you have a idea, i will be very greatful :)

thanks so much for the report! will investigate

currently it seems to crash when zooming out of the "blue" grid, after rendering any 3-D model at any previous time in the same process. investigating.

Thanks for the comment, I didn't test once again, but I think that the problem also appear sometime between the "yellow" and the "green" grid. But in fact, It could appear when the grid is changing.

we believe it only happens on certain computers. could you write here the spec of the computer that this crash happens on?

[tdelc]

Windows 8.1 64 bits ; Quad CPU 2.33Ghz ; RAM : 4 Go ; EE compiled with Codeblock. I didn't test with a other computer.

What GPU?

[tdelc]

sorry, CPU = GPU in french :)

[amir-arad]

I mean: what model of graphic card?

[tdelc]

ah ok, I am not in my house, I say you this night

[tdelc]

NVIDIA GeForce GTX 780

so in all our findings, the computers who consistently displayed this bug (4 so far) had a graphic accelerator (Nvidia in all of them I think), and the computers who do not have this bug (3 so far) don't have any additional accelerator other what comes in their i3/5/7 CPU. I don't have regular access to a computer with an accelerator card (Murphy's law) so i can't debug.

My assumption is that the 3-d rendering changes the mode of the accelerator by one of the GL API methods (probably here), and that state causes a crash when the radar view does its layering tricks and things are so close together they overlap.

• The best solution would be to reset the GL state when switching between stations, but that will require some debugging and experimentation on a computer with an accelerator. If you're willing to take it on I can offer guidance.
• Another would be to not render 3-d in the dockmaster view (just delete the rotating 3d component). I am willing to do that in my branch if it helps.
• A third solution, which is what happens in our LARP, is not to use the same computer for more than one station.

what do you think?

[tdelc]

I confirm that on a other PC without accelator card, I don't have the bug.

For this week end, I will use only one computer by station, so it will be ok. After that, yes, I would be interested to reset the GL state each time. Deleting the 3D ship into the docks master is not a good solution for me, because it is pretty cool to see the drone.

Thanks for your findings !

have fun storming the castle!

Thanks !

It's still an issue I would like to solve. maybe not a top priority right now, but no reason closing it
