How does pathfinding work in 2D games?
Pathfinding in 2D games typically uses algorithms like A* or Dijkstra's to find the shortest route from one point to another.
What is the A* algorithm and how does it differ from Dijkstra's?
The A* algorithm uses heuristics to prioritize paths, making it faster than Dijkstra's, which explores all possible paths equally.
Can you give an example of how A* is implemented in a game?
Sure! In a grid-based game, A* evaluates neighboring nodes based on cost and heuristic, updating the path as it finds shorter routes.
What are some common challenges in implementing pathfinding?
Common challenges include handling dynamic obstacles, optimizing performance for large maps, and ensuring smooth movement.
