Title: Exception Thrown at line where I defined sf::Texture
Post by: sadin97 on September 14, 2017, 10:34:28 pm: Code: [Select]
Exception thrown at 0x7749B2E3 (ntdll.dll) in App.exe: 0xC0000005: Access violation writing location 0x00000004.
At line:

Code: [Select]
sf::Texture seaTexture;
In file resources.cpp

I also put:

Code: [Select]
extern sf::Texture seaTexture;
in file resources.h

So... can I do something like this. Im using seaTexture in another file so I tried to put extern to it.

Make sure everything is matching and that you don't have old libraries and keep in mind that VS comes with two kinds of compilers, one for x86 and one for x64, you have to pick the right one.

Are you sure that is the problem? I can use generally sf::Texture... but with this making it extern I got problems.

They do internal stuff during their construction and destruction, which involves other global variables that may not be available due to non-deterministic order of initialization of globals.

So... any hint? How should I use same texture in other file if it is even possible?

Pass by reference.

Can you post some simple examples using textures?
