VC++ 10 binaries are compatible with VC++ 11, you don't need to recompile SFML;

And VC++ 11 (compiler) = VS 2012 (IDE). There's no Visual Studio 2011.

Nice...
Have i to compile with cmake to get 64bit version for VS?

Cmake can't build SFML for VS11 RC! There is a way to build it manually?

Yes, I would try VS11. The CMake generator was conceived for VS11 Developer Preview or Beta though.

Ok, if it won't work how can i use SFML2 under VS11?

Please write Microsoft or MS, if you want to be taken seriously.

Yes, sorry for this!

Yes, the precompiled libraries are probably not compatible.

Uhm, cmake can build for Visual Studio 11... is that the right build,isn't it?
(VS11 = visual studio 2012 if i'm right)

even on VS 2010 most C++11 features supported, sfml2 on 2012, why not ?

I'm downloading 2012, but have i to build with Cmake SFML2 for better support of SFML in VS2012?

I see that M$ releases VS2012! Now i've some question about:
How much of you use VS2012 RC?
How is C++11 support?
Can i still use sfml2 under VS2012?

I'm getting crazy with update and draw chunks I don't know how to code it.
I've a matrix wich represent my tilemap and where i can build tiles.
Chunk size is 8x8 tile
Chunks are std::vector<sf::VertexArray> (maybe i've to code a Chunk class, so i can manage something more than the tilemap)
How can i code a fast and good chunks system? :S
I was thinking about using a IntRect > windowView and calculate tiles coordinates in tile (x*256,y*256) and tehn build and draw chunks taht cover all points inside IntRect... its a good way or there is a more flexible way to manage them?

_msize() doesn't work like that. You should read the documentation of unknown functions before using them:

The _msize function returns the size, in bytes, of the memory block allocated by a call to calloc, malloc, or realloc.

There is no portable way to find out how much bytes are totally allocated by an arbitrary object.

Oh yes xD Sorry! I read only some forum posts taht said it used to know bytes and i used it
Ok, thx for fast reply

There is a way to rotate 90° a texture that normally is not rotated in tileset?

Rotate the texture coordinates of the quad.

Nice! 
Now i want to see how much memory (in bytes) each item uses. I read aroud about _msize for VS10, but i get a debug error wich say that the poiter i use is invalid or something like that:

std::cout << "The Matrix size allocated is " << _msize(mapMatrix) << " bytes!"<<std::endl;
std::cout << "The MyMap size allocated is " << _msize(&myMap) << " bytes!"<<std::endl;
std::cout << "The MyMapChunk size allocated is " << _msize(&myMapChunk) << " bytes!"<<std::endl;
 

mapMatrix is a sf:Uint16 pointer
myMap is sf::VertexArray
myMapChunk is a std::vector<sf::VertexArray>
The error appear at _msize(&myMap).
There is a better way to know how much bytes each item uses?

There is a way to rotate 90° a texture that normally is not rotated in tileset? Or have i to draw the same texture  rotated and put it in tile set?

void CSprite::setRotation(float degrees)
{
   drawable.SetOrigin(get_width()/2, get_height()/2);
   drawable.SetRotation(degrees);
   drawable.SetOrigin(0, 0);
}

Ok i'm testing for chunks, but i get some errors.
I put in my TileMap class a

std::vector<sf::VertexArray> mapChunks

For my test i want to draw only a 2x2 section of my map that start from (0, 0) coordinates.
So i build a function that store in a vertexarray the right vertex and then store the vertexarray inside the vector.
Then i call draw

window.draw(mapChunks[0],&tilesTexture);

It draws nothing
I used the same algorith to build and draw the normal huge map (it draws well), but this tme it wil lbe limited only to a 2x2 matrix.
I checked memory with debugging and vertexarray inside the vector has the same vertexs of normal big map vertexarray.
Why it doesn't draw my small tilemap? What is my mistake?

EDIT: Error found, i forgot to set primitive type xD Now it draws well 2x2 map

Ok, i will make some tests to reach this goal

Yes, it is crazy to make 3900x3900 xD
300x300 is alredy too big and take too much to "walk" all around. So probably i will limit the map size to 300x300
1000x1000 (and 3900x3900) are just tests, if i could draw 1000x1000 map without FPS crash it will be very usefull, so i can draw all size below 1000x1000 with an high framerate

So now, my question is: to manage chunks, will i need to split vertexarray map in n small vertexarray? Or there is a better and coolest way to do it?

Graphics / VertexArray for tilemap

« on: May 31, 2012, 12:13:12 am »

Ok, now i made a functional tilemap, but i foud a limit... cus VertexArray is a std::vector<Vertex> i can't make a 3900x3900 tile map (60 milion of vertex)
Due to private member i can't know m_vertices.max_size()
For the moment i can generate and build a 32x32*256px tilemap in some microseconds and draw it in 10 microseconds
My question, how can i know the max size of m_vertices?

For the moment i get crash at this line:

myMap.resize(nrows*ncols*4);
 

EDIT:
Ok i see that i will get some FPS crash with 350x350 map. So i suppose to set max map size to 300x300 which is the last stable FPS map size!
