Bug Reports / RFE / [BUG] Rare and Random crashes ...

Last post by Lankyware - March 07, 2024, 12:46:46

Ok so in my indie game, the game will randomly crash like once every 3 hours or so on average. It gives the message: A fatal error has been detected by the Java Runtime Environment. And it makes a log file. I've looked into it a lot and haven't been able to find out what causes this. This article is the closest I've found to an answer: https://inside.java/2020/12/03/crash-outside-the-jvm/
Error log file: https://gist.github.com/dfu1/253cc2f51b372027109dc99604b2c4ed
I've taken a look in the log file, and in the Java frames part it shows there was a call of org.lwjgl.opengl.GL11C.glDrawArrays(III)V.
And in the Internal exceptions, it says there's a java/lang/NoSuchMethodError exception.
I cannot figure out what the cause is, and I don't understand why it would be happening so rarely and randomly.
Any explanations/ideas are welcome.

How do I make a 3d camera in java and lwgl that can look around with mouse and can move around with key binds, like roblox studio's workspace camera.

Cheers, Shreyank6189

Hey Dmytro,

You can find some fairly advanced demos here: https://github.com/LWJGL/lwjgl3-demos

LWJGL Documentation / Moving circle emaple wanted

Last post by Dmytro - February 02, 2024, 00:02:09

Hello!

I'm pretty new to LWJGL world.
At this moment I installed everything and sucessfully run example from title page.
But I need more complex example to start develop my project.

Ideally it should be a simple application of bouncing ball or similar. Later I will develop a simulation of planets with field of gravity.
The computation engine is ready need only high-performance graphics. I suppose LWJGL is wnat I need.

Thanks and Regrads,
Dmytro.

Hello Spasi

Thank you very much.
That worked great !
Just added this:

while (!glfwWindowShouldClose(handle)) glfwWaitEvents();

Hey aerodash,

Please see https://github.com/LWJGL/lwjgl3/blob/master/modules/samples/src/test/java/org/lwjgl/demo/stb/Vorbis.java for a working example of multithreaded UI (i.e. the event loop), rendering and audio.

The recommended approach is to use the main thread for the event loop (with glfwWaitEvents) so that you're always consuming UI events, then spawn secondary thread(s) for rendering and audio. This works nicely on macOS too (where the event loop must always be on the first thread of the process). Rendering never stops, even while dragging the window.

OpenGL / Error when creating window and...

Last post by aerodash - January 22, 2024, 23:33:54

Hello

I am trying to do all rendering on a separate thread.
What I am doing right now is the following:

glfwInit();
long handle = glfwCreateWindow(800, 600, "Demo", NULL, NULL);
new Thread(() -> {
  glfwMakeContextCurrent(handle);
  GL.createCapabilities();

  int shader = loadShaders();
  int vao = createVao();

  while (!glfwWindowShouldClose(handle)) {
    glUseProgram(shader);
    glBindVertexArray(vao);
    glDrawArrays(GL_TRIANGLES, 0, 3);

    glfwSwapBuffers(handle);
    glfwPollEvents();
  }
}).start();

With the above code, rendering works as I can see a triangle but the window is not responsive.
When moving or clicking on the window the process would stop responding.
