Hi,
I am trying make an A* algorithm. My algorithm works good without walls but when i add walls it doesnt work i don't know why full code :
A-StarTest01.zip

And this is the main finding function:
Qt Code: 
  1. void PathFinder::findPath()
  2. {
  3.     pathFind = false;
  4.     openList.clear();
  5.     closedList.clear();
  6.     QQuickItem *currentItem = start;
  7.     QList<QQuickItem*> path;
  8.     closedList.append(start);
  9.     findNeighbors(currentItem);
  10.     while(!openList.isEmpty())
  11.     {
  12.         findNeighbors(currentItem);
  13.         QQuickItem *minimal = openList.first();
  14.         foreach (QQuickItem *item, openList)
  15.         {
  16.             int minF = getF(currentItem, minimal);
  17.             int itemF = getF(currentItem, item);
  18.             if(itemF < minF)
  19.             {
  20.                 minimal = item;
  21.  
  22.             }
  23.         }
  24.         currentItem = minimal;
  25.         closedList.append(currentItem);
  26.         path.append(currentItem);
  27.  
  28.         if(currentItem == finish)
  29.         {
  30.             pathFind = true;
  31.             path.removeOne(currentItem);
  32.             drawPath(path);
  33.             break;
  34.         }
  35.     }
  36.  
  37.     qDebug() << (pathFind ? "path finded" : "no path");
  38.  
  39. }
