1) Load base resources A.
2) Load extra resources B.
3) Unload extra resources B.
4) Load extra resources C that are just different versions of resources B (same names, different pictures)
I can't find a good way to do this.
I found this thread http://cegui.org.uk/forum/viewtopic.php?f=10&t=6586 was helpful and relevant.
My suggestion is that CEGUI should have a better way to handle loading and unloading blocks of resources. I want to unload all images relevant to B, but not unload anything in A. That's really tough to do right now.
Anyway, back to my problem. My workaround is:
1) Load base resources A.
2) Load extra resources B.
3) Unload all resources.
4) Load base resources A.
5) Load base resources C.
The issue I am having with this is I get access violation reading location 0xABABABAB when attempting to reload the layout in resources A. I can reload the schemes, imagesets, and fonts without exception.
CEGUI/Window.cpp where the exception is thrown
Code: Select all
const RenderedString& Window::getRenderedString() const
{
if (!d_renderedStringValid)
{
// FIXME: Evil const cast!
d_renderedString = getRenderedStringParser().parse(
getTextVisual(), const_cast<Font*>(getFont()), 0); // ** THIS LINE **
d_renderedStringValid = true;
}
return d_renderedString;
}My call stack:
