Man, I just wanna thank you for all these amazing tutorials, I'm from Brazil and fortunately I know some english, so I can understand, after all, there's no such a great series like this that I've found...thank you again. (sorry for bad english).

+Bitan Mandal Nah just finding a paying job and moving across the country! I am settling in now and should be able to get on a video schedule. I want to release one every Sunday at least, could probably make that happen.

To eliminate certain warnings, I would use:

case SDL_MOUSEMOTION:
m_context->injectMousePosition((float)evnt.motion.x, (float)evnt.motion.y);

...added in (float) to that, otherwise the compiler complains.

Also...

case SDL_TEXTINPUT:
cs = CEGUI::String((CEGUI::utf8*) evnt.text.text);
for (size_t i = 0; i < cs.size(); ++i) m_context->injectChar(cs[i]);

...for that code, I changed "int i" to "size_t i", otherwise you get more compiler warnings.

I also removed all the libraries from Bengine or you get more warnings as Bengine doesn't need them. Instead I add them to each project. More warnings removed that way.

Finally, when I compile in debug mode I get some warnings that have to do with linking in non-debug libs with a debug version of the executable, this is not a problem, so I added: "/NODEFAULTLIB:library " to the Linker->Command Line additional properties.

When all was done, I was able to compile everything with zero warnings! (I hate warnings). ;)

Question for anyone who has an idea for an answer:
What if I wanted to have multiple next screens? For example: An options screen and a play screen accessible from the main menu. Would I use if statements in the getNextScreenIndex function?

Would you recommend using this implementation when a player enters a building, or moves to a new part of the overworld map. (I want to create an original final fantasy style game, where user roams overworld and walks onto a building to enter the town. (also similar to the adventure or link..the second zelda game for nes).

Hi Ben,

In your vertex shader, Y-axis of the texture was flipped by 1.0- vertexUV.y ;
fragmentUV = vec2(vertexUV.x, 1.0 - vertexUV.y)

If we decided to send the actual UV as it is without flipping the Y coordinate to the fragment shader, then how can the rendered image be flipped on its Y-axis without messing up the coordinate system for inputs and so on?

Thanks.
