What are some common pathfinding algorithms used in AI for NPCs?
Some common pathfinding algorithms include A*, Dijkstra's algorithm, and Breadth-First Search. A* is particularly popular for its efficiency.
How does the A* algorithm work?
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.
Can you give an example of a game that uses pathfinding algorithms?
Sure! Many games like 'The Legend of Zelda' and 'StarCraft' use pathfinding algorithms to control NPC movement and navigation.
