Hi there,
I recently switched from JOGL to LWJGL and I'm currently porting my engine.
Sadly I encountered the following problem:
Creating 16 buffer
16 capacity, 0 remaining, 16 position, .. flipping..
flipped
16 capacity, 16 remaining, 0 position
Exception in thread "main" java.lang.IllegalArgumentException: Number of remaining buffer elements is 4, must be at least 16. Because at most 16 elements can be returned, a buffer with at least 16 elements is required, regardless of actual returned element count
at org.lwjgl.BufferChecks.throwBufferSizeException(BufferChecks.java:162)
at org.lwjgl.BufferChecks.checkBufferSize(BufferChecks.java:189)
at org.lwjgl.BufferChecks.checkBuffer(BufferChecks.java:244)
at org.lwjgl.opengl.GL11.glGetInteger(GL11.java:1355)
Please note the debug statements, where i create a floatbuffer from my camera matrix. Nonetheless, this error keeps occuring. As far as google told me, this error was supposed to be resolved by flipping the floatbuffer, but i already did so:
glLoadIdentity();
System.out.println("Creating "+(entity.getMatrix().get().length)+" buffer");
FloatBuffer floatBuffer = BufferUtils.createFloatBuffer(entity.getMatrix().get().length);
floatBuffer.put(entity.getMatrix().get());
System.out.println(floatBuffer.capacity()+" capacity, "+ floatBuffer.remaining()+" remaining, "+ floatBuffer.position()+" position, .. flipping..");
floatBuffer.flip();
System.out.println("flipped");
System.out.println(floatBuffer.capacity()+" capacity, "+ floatBuffer.remaining()+" remaining, "+ floatBuffer.position()+" position");
glLoadMatrix(floatBuffer);
Thank you for your help.
