path-finding

I have a worldmap, with different cities on it. The player can choose a city from a menu, or click on an available cities on the world map, and the toon should walk over there.

I want him to follow a predefined path.

cities

Lets say our hero is on the city 1. He clicks on city 4. I want him to follow the path to city 2 and from there to city 4.

I was handling this easily with arrow movement (left right top bottom) since its a single check.

Now I'm not sure how I should do this. Should I loop threw each possible path and check which one leads me to D the fastest ... and if I do how do I avoid running in circle forever with cities 1-5-2 ?

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.
