What are the common algorithms used for pathfinding in video games?

Some common algorithms include A*, Dijkstra's, and Breadth-First Search. A* is particularly popular for its efficiency.

Can you explain how the A* algorithm works?

Sure! A* uses a heuristic to estimate the cost from the current node to the goal, combining it with the cost to reach the current node.

What are the advantages of using A* over Dijkstra's algorithm?

A* is generally faster than Dijkstra's because it prioritizes paths that are likely to lead to the goal, reducing unnecessary exploration.

Are there any limitations to using A*?

Yes, A* can be less efficient in certain scenarios, especially if the heuristic is not well-designed or if the search space is very large.
