Oh, sorry..hybrid wrote:You didn't change the second s32 to u32...
I was change it to u32 because i got a "segmentation fault",
via debugger i found the problem, and was this (Now it's commented):
Code: Select all
//Sky->setMaterialType(video::EMT_TRANSPARENT_ALPHA_CHANNEL);
Update:Innopeor wrote: Oh, sorry..

The problem "segmentation fault" was not do from:
Code: Select all
//Sky->setMaterialType(video::EMT_TRANSPARENT_ALPHA_CHANNEL);
"return 0;" is correct.
Code: Select all
virtual u32 getMaterialCount() const //editato const
{
//return 1; editato
return 0;
}

It works!!!!hybrid wrote:Don't know what you change and what crashed, but you *must* change the s32 in getMaterial to u32. And you will probably have to recompile the whole project to get the header files updated. Otherwise it might crash...
Thanks for your BIG help!

This example compiles without errors, but when i run the program, i get an error "atmosphere.exe has encountered problems and needs to be closed...". Checking the console i see that the media which i have loaded from ATMOsphere.cpp has failed to load. I copied the media files to irrlicht/media but i get the same error.
