Title: 0xC0000005 when drawing drawable
Post by: denis318 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
Quote
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:
Quote
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:
Quote
vector<vector<Drawable*>> layerr
its haves size 1, but i drawing to layer 0(first) and layers being initialized by:
Quote
void Engine::AddLayer(unsigned short layernum)
   {
      vector<Drawable*> tempvector;
      Engine::layerr.push_back(tempvector);
   }

So when it crashes, what's the call stack?

When it crashes can you check what the layer contains, i.e. whether it's valid?

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)

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
