![]() ![]() Dijkstra’s Algorithm - adds weights to edges.Breadth First Search - unweighted edges.One source, all destinations, or all sources, one destination:. ![]() There are lots of different graph search algorithms we could use in this type of game. You can use this for each enemy to find a path to the goal. Graph search algorithms like A* are often used to find the shortest path from one point to another point. Enemies will move in the direction that gets them closer to the player: To solve this problem we need either a vector field (also called a flow field) or a distance field (also called a Dijkstra Map). Try it out, and click on the map to toggle walls. In some, such as the classic Desktop Tower Defense, you can place towers anywhere, and they act as obstacles that affect the paths taken by enemies. In many Tower Defense games, there is a predetermined path, or a small number of paths. In a Tower Defense game, there are many enemies that are all headed to the same place. ![]()
