A* algorithm

[Ichi]

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:

void PathFinder::findPath()
{
    pathFind = false;
    openList.clear();
    closedList.clear();
    QQuickItem *currentItem = start;
    QList<QQuickItem*> path;
    closedList.append(start);
    findNeighbors(currentItem);
    while(!openList.isEmpty())
    {
        findNeighbors(currentItem);
        QQuickItem *minimal = openList.first();
        foreach (QQuickItem *item, openList)
        {
            int minF = getF(currentItem, minimal);
            int itemF = getF(currentItem, item);
            if(itemF < minF)
            {
                minimal = item;
 
            }
        }
        currentItem = minimal;
        closedList.append(currentItem);
        path.append(currentItem);
 
        if(currentItem == finish)
        {
            pathFind = true;
            path.removeOne(currentItem);
            drawPath(path);
            break;
        }
    }
 
    qDebug() << (pathFind ? "path finded" : "no path");
 
}

void PathFinder::findPath()
{
    pathFind = false;
    openList.clear();
    closedList.clear();
    QQuickItem *currentItem = start;
    QList<QQuickItem*> path;
    closedList.append(start);
    findNeighbors(currentItem);
    while(!openList.isEmpty())
    {
        findNeighbors(currentItem);
        QQuickItem *minimal = openList.first();
        foreach (QQuickItem *item, openList)
        {
            int minF = getF(currentItem, minimal);
            int itemF = getF(currentItem, item);
            if(itemF < minF)
            {
                minimal = item;

            }
        }
        currentItem = minimal;
        closedList.append(currentItem);
        path.append(currentItem);

        if(currentItem == finish)
        {
            pathFind = true;
            path.removeOne(currentItem);
            drawPath(path);
            break;
        }
    }

    qDebug() << (pathFind ? "path finded" : "no path");

}

Use your debugger. Learning how to is not optional for programmers
