Issue with cache of pictures

[JasonLeon]

I wanted to cache pictures at the beginning, using map<string, Texture>cache to store the info of the image. I wrote the code
cache[filename].loadFromFile(xxx);
but the program crashed.
I also used the ways below.
Texture temp;
temp.loadFromFile(xxx);
cache[filename]=std::move(temp);
Still did not work.
Seems like the Texture kind object cannot use '='?

I just tested your first version, it works fine. (I usually use texture pointers in my resource system map, but textures work too)
Are you sure that's the part causing the crash?

That's really confusing. I'm sure the file is existed.😥

I wrote this and the program crashed here:
textureCache[string("animation\\") + fileinfo.name].loadFromFile(string("..\\graphics\\animation\\") + fileinfo.name);

Sorry guys. I found out that it was the loop's fault. Problem solved.
