path-finding

I've implemented AStar in Java and it works ok for an area with obstacles where the chosen destination is reachable.

However, when the destination is unreachable, the calculated "path" is in no way to the closest location (to the unreachable location) but is instead some random path.

Is there a feasible way to tweak AStar into finding the path to the closest location to an unreachable destination?

How do you know when a path-finding algorithm is really needed? There are contexts, where you just want to improve AI navigation to avoid an object, like a space -ship that won't crash on a planet or a car that already knows where to steer, but needs small corrections to avoid a road bump.

The venerable shortest-path graph theoretic algorithm A* and subsequent improvements (e.g., Hierarchical Annotated A*) is clearly the technique of choice for pathfinding in game development. Instead, it just seems to me that RL is a more natural paradigm to move a character around a game space. And… >>> More

Hi, I wanted to implement the game Pacman. For the AI, I was thinking of using the A* algorithm, having seen it on numerous forums. However, I implemented the Breadth First Search for some simple pathfinding (going from point a to point b with certain obstacles in between) and found it gave the optimum… >>> More

If you needed a clean and consistent sandbox for pathfinding what would you use? I want to experiment with different pathfinding algorithms by sending virtual units (robots) around obstacles on a geometric plane. But I don't need a feature overkill like a game engine or Flash might have, just an… >>> More

I am working on a roguelike in my (very little) free time. Each level will basically be a few rectangular rooms connected together by paths. I want the paths between rooms to be natural-looking and windy, however. For example, I would not consider the following natural-looking: B … >>> More
