示例1: FindPath
TileVector PathFinder::FindPath() const
{
TileSet closed = {};
TileSet open = { &m_source };
CostMap g_score; // Cost from start to this node.
CostMap f_score; // Cost to get to this node + estimated cost to dest.
CameFromMap cameFrom;
g_score[&m_source] = 0;
f_score[&m_source] = _Heuristic(m_source, m_dest);
while (!open.empty())
{
// Take the element in the open set with least total estimated cost.
Tile* curr = *std::min_element(open.begin(), open.end(),
[&f_score](Tile* a, Tile* b)
{
return (f_score[a] < f_score[b]);
});
if (curr == &m_dest)
{
// We've found the best path.
return _Reconstruct(cameFrom, m_dest);
}
open.erase(curr);
closed.insert(curr);
for (Tile* neighbour : _Neighbours(m_map, *curr))
{
if (closed.find(neighbour) != closed.end())
continue;
int tentative_g_score = g_score[curr] + neighbour->MoveCost();
// If neighbour isn't in the open set, or we have found a better path to neighbour, update it.
if ((open.find(neighbour) == open.end()) || (tentative_g_score < g_score[neighbour]))
{
// This could be done without recalculating the heuristic, if desired.
cameFrom[neighbour] = curr;
g_score[neighbour] = tentative_g_score;
f_score[neighbour] = tentative_g_score + _Heuristic(*neighbour, m_dest);
open.insert(neighbour);
}
}
}
// Failure
printf("No path\n");
return{};
}示例2: ForEachReachableTile
void Map::ForEachReachableTile( const Unit* unit, ForEachReachableTileCallback callback )
{
assertion( unit, "Cannot find reachable tiles for null Unit!" );
assertion( callback.IsValid(), "Cannot call invalid callback on reachable tiles!" );
// Find all reachable tiles for the Unit.
TileSet reachableTiles;
FindReachableTiles( unit, reachableTiles );
for( auto it = reachableTiles.begin(); it != reachableTiles.end(); ++it )
{
// Invoke the callback on all reachable tiles.
callback.Invoke( *it, unit );
}
