Cool! Yes, those are important. Essentially all the other sets/gets just
change variables, but to fix dependent data and to make everything
consistent the begin/endEdits are needed.
I have a new problem. :-(
I have set up my viewport with all the stuff its needs. I have
begin/endEdits included. I have set up my PolygonForeground with a
Material and the positions and texcoords. The material has normally a
SHLChunk and a TextureChunk, but now only a TextureChunk. This
TextureChunk is my problem. My particles have a size of 2^n, because of
the 2D textures. When I change the number of my particles, I have to
resize the viewport to sqrt(size_of_particles).
That works fine, but I have to renew the image for the TextureChunk. And
this is the problem. The new image has a different size. That's why I
set the new image to the TextureChunk. (By the way, what does happen to
the old image? Is there something like a garbage collector, or will it
be overwritten?) But after changing the size 2-3 times, it crashed. It
doesn't crash when I clear the following lines:
// this is the size of the particles
_iVpSize = (int)sqrt((double)_mgr.getParticles().getNumber());
// change the texture chunk
beginEditCP (_tcInput, TextureChunk::ImageFieldMask); {
if (_iVpSize == 8) _tcInput->setImage(_imIndices[0]);
if (_iVpSize == 16) _tcInput->setImage(_imIndices[1]);
if (_iVpSize == 32) _tcInput->setImage(_imIndices[2]);
if (_iVpSize == 64) _tcInput->setImage(_imIndices[3]);
_tcInput[1]->imageContentChanged(); // I wonder if this is
necessary?!
} endEditCP (_tcInput, TextureChunk::ImageFieldMask);
Do I have to change anything else?
The funny thing is, when I debug my program, I get different reasons why
it crashed.
Here is the first one, my debugger just hang up and I cancelled (and
this is the most frequently one):
Program received signal SIGINT, Interrupt.

And this one is also very famous:
