Crash when testing Britzl simple lights example

#1

Hello, I was trying to run Britlz’s “Simple Lights” example (https://github.com/britzl/publicexamples/tree/master/examples/simple_lights) and when I run the project I got the screen and after 1 second the example crashes with this result:

Can you try this fork and see if it still crashes for you? I tried to update a few things

This as is runs for me without warnings and no crashes on Windows 10.

Well I tried it, even restarted the computer and it’s still crashing. I use Windows 10 and my graphics card is NVIDIA Geforce 1050 2GB, I5 processor (2nd generation) 8 GB memory. For hard drives I have 1 SSD for the main system and SATA2 500gb for data. Screen resolution 1920x1080, 1080p in 60hz. I will paste below the sysinfo from Nvidia panel, it might help altough it’s in portuguese:

Could you try disabling parts of the example until you can figure out what exactly is causing the crash? Use -- to comment out lines and look for whatever is causing the issue.

This is the main file you want to experiment with /examples/simple_lights/simple_lights/render/postprocess.render_script

If the function update(self) try to disable parts. You can toggle comment out multiple lines by highlighting them and press Ctrl + /

@Mathias_Westerdahl might know what’s wrong based on the call stack.

Sure, I’d love to help fix this. Thanks for the tip on the “comment multiple lines”, I need it. Since it’s kinda late here, I’ll post the results tomorrow.

Unfortunately, that callstack looks broken. Those functions seem very arbitrary.

If you could upload the _crash.dmp, I could debug using that.

Hello Mathias. Here are both crash files in ZIP (I didn’t saw the zip format was allowed to upload until now, sorry guys). It was generated a few moments ago, right after the update. Hope you can fix it.

Guys, I did right now what Pkeod suggested, and I got success identifying the line in the render script (in function update) that generates the problem. After commenting the line

render_helper.set_screen_view_projection(self)

the scene loaded and run without errors.

Are you using any native extensions?
If so, could you share the dmengine.exe that you built?
And preferably, if you build with bob.jar, if you add the “–with-symbols”, you’ll also find the dmengine.pdb in the bundled folder.

(Yes, I really need to add the “–with-symbols” as default when building with the editor)

Mathias, I was trying to do what you asked when I find out the following: the project builds OK, with no errors (even with that line uncommented) if I press CTRL+B or CTRL+SHIFT+B, but when I try to run the game (from the editor) with F5 key (as I use to do) the error occurs.

For me, F5 was just another way to reach the same result as CTRL+B but apparently they are different procedures.

Edit: I have luasocket installed, only.

Do you use any dependencies in your project?
I.e. “project -> dependencies” in the game.project settings.

No dependencies, I ran the example project as it came. I noticed however it uses ortho camera. Anyway the problem seems to be only when I run the project from the editor with the F5 key as I stated above.

Pressing F5 in the editor builds the game with a debugger which has some issues, though this seems to be a new error. Does the same thing happen if you run other projects with F5?

Not really, BUT I haven’t tried many examples yet. Mostly my own studies reading the manuals. So far I’ve been using rendercam in my project, but I recently made some study in a separate project using normal camera and all went ok.
