General / Detecting collision direction uncorrect

« on: October 05, 2017, 11:23:17 am »

I have a four FloatRects, that anwser for sprite animation frames collision directions, i initialize it for each frame in Animation.h
ColPointDivide its a integer that equals 10, i use it that the edges do not intersect (up-right,up-left,etc...)
i.e i want to create a FloatRect (Collision box) that little offseting from top to bottom Y points, trying deny edges intersecting

      *leftRect = FloatRect(
         0,
         R.height / ColPointDivide,
         R.width / 2,
         R.height - R.height / ColPointDivide
      );
      *upRect = FloatRect(R.width / ColPointDivide,
         0,
         R.width - R.width / ColPointDivide,
         R.height / 2);
      *rightRect = FloatRect(R.width / 2, R.height / ColPointDivide, R.width / 2, R.height - R.height / ColPointDivide);
      *downRect = FloatRect(R.width / ColPointDivide, R.height / 2, R.width - R.width / ColPointDivide, R.height / 2);

In code when i want to check collision, i trying this:
(mtv its a SAT mtv, that contains collision depth, like 0,1)
(curColRect its an array vector of FloatRects with size 4, i calling i needed direction, and current animation frame)

for each (Block bl in m_engine->MapBlocks)
      {
         FloatRect blrect = bl.sprite.getLocalBounds();
         //auto B = bl.sprite.getLocalBounds();
         
         //RectangleShape colupshape(Vector2f(curAnim.Col_up.width,curAnim.Col_up.height));
         //colupshape.setPosition(curAnim.Col_up.left, curAnim.Col_up.top);
      //   m_engine->AddSprite(&colupshape, 0);
         Vector2f mtv;
         if (m_engine->m_math.sat_test(bl.sprite, kidspr, &mtv))
         {
            FloatRect mtvrect(mtv.x, mtv.y, blrect.width-mtv.x, blrect.height-mtv.y);
      //      coutMTV(mtv);
            if (!passed[ColPoint::up])
            {

               if (mtvrect.intersects(curColRect[ColPoint::up].at(curf)))
               {
                  setPos(
                     Vector2f(
                        kidentity->GetX(), bl.sprite.getPosition().y - kidentity->anim.getSprite()->getOrigin().y
                     ));
                  colUP = true;
                  passed[ColPoint::up] = true;
                  
               }
            }

// and that for each direction...

I also setting false all booleans to false above, and its method calling with gameloop some often like drawing, under i setting booleans that wasnt colliding to false
(under code)

if (!passed[cp::left])

   }

   Sprite kidspr = *kidentity->anim.getSprite();

So, when my sprite with animation collides to a block by up, ALL booleans that anwser for collision (colDOWN,colLEFT,colRIGHT,colUP) are true, but collision was by up point...
I also trying use CurColRect[point][curf].contains(mtv), but this work veery strange, when collision by up, all collision booleans are false, only colLEFT are true, idk why
Please help me, idk what is wrong
I also dont want to use Box2d for its objectives
I use SFML 2.4.2
sat_test method:

bool Iwmo::Math::sat_test(const sf::Sprite &sp1, const sf::Sprite &sp2, sf::Vector2f *out_mtv) {
      const sf::FloatRect &rectSp1 = sp1.getGlobalBounds();
      const sf::FloatRect &rectSp2 = sp2.getGlobalBounds();
      float proj_x, proj_y, overlap_x, overlap_y;

      // test overlap in x axis
      proj_x = std::max(rectSp1.left + rectSp1.width, rectSp2.left + rectSp2.width) - std::min(rectSp1.left, rectSp2.left);

General / Re: 0xC0000005 when drawing drawable

« on: September 19, 2017, 03:45:28 pm »

Oh, after many tests, i solved it.
Programm was crashing because tmx::MapLoader must be drawn in thread when it created, i created support boolean gamestarted and now creating a map in Engine class, that contains method to rendering.
Or its was because my map was local,
most likely the second

If i understood right, layer 0 size is 1 when crashing (ie it contains map Drawable in it,so that valid i think)
(my layer, not TMX)

also now it crashes with error 0x00007FFEFD0334BE (ucrtbase.dll) and showing this lines in MapLoaderPrivate.cpp
(idk what)

for(auto& layer : m_layers)
      rt.draw(layer);

sorry if it wrong call stack, i dont know completly what is it

General / 0xC0000005 when drawing drawable

« on: September 17, 2017, 01:41:18 pm »

I have a function AddSprite(Drawable*, unsigned short), that adding Drawable to 2d vector with given layer number(as two parametr)
Its works perfectly, but when i added MapLoader ( its a fallahn`s sfml-tmxloader  MapLoader that extends Drawable) to 0 layer and rendered it, i got 0xC0000005 error, i checked my layers numbers, all fine, map being loaded, i dont think what is wrong, my code below

tmx::MapLoader map("resources/");
         map.addSearchPath("resources/blocks/");
         
            if (map.load("map.tmx"))
            {
               if (debug) {
                  cout << "map loaded!" << endl;
               }
            }
            else
            {
               if (debug) {
                  cout << "MAP NOT LOADED!" << endl;
               }
            }
            engine->AddSprite(&map, 0);
         //

my rendering code:

inline void Engine::render()
   {
      while (window.isOpen())
      {
         window.clear();
         for (unsigned int i = 0; i < Engine::layerr.size(); i++)
         {
            for (unsigned int i1 = 0; i1 < Engine::layerr.at(i).size(); i1++)
            {
                  window.draw(*(Engine::layerr.at(i).at(i1)));
            }
         }
         window.display();
      }
   }

(i using multithread rendering, so rendering occurs in another detached thread)
my vector looks like this:

vector<vector<Drawable*>> layerr

its haves size 1, but i drawing to layer 0(first) and layers being initialized by:

void Engine::AddLayer(unsigned short layernum)
   {
      vector<Drawable*> tempvector;
      Engine::layerr.push_back(tempvector);
   }

sfml-tmxloader https://github.com/fallahn/sfml-tmxloader is last version
SFML is 2.4.2
Tiled version is 2017.05.26
с++ version is 17 (2017) and visual studio same 2017
i using static SFML,static zlib,x64 architecture and static TMX (TMX_STATIC flag)
sorry for my bad english
Please anybody help me, i dont known what is wrong
my map with tsx and textures in archive attached below

I am trying to use many examples of sfml network, but he dont work, i test .exe in another pc but same problem.Problem is "Failed to bind listener socket to port (port)".Ports are opening for tcp and i trying to code it with tcp.I tryed to use TCP.CPP from sfml examples but it dont work too.Why? Includes are included , visual studio 2015 setting are well...
Sry for english
sfml 2.4
firewall is ok
