It does not make a difference for the path finding algorithm but it might be useful for your later map evaluation. Note: you can use negative values to describe different types of obstacles. Feel free to create a more complex map or use some sensor data as input for it. We ignore the weight for now, all fields have the same cost of 1. To make it not to easy for the algorithm we added an obstacle in the middle, so it can not use the direct way. ![]() In this example we like the algorithm to create a path from the upper left to the bottom right. The bigger the number the higher the cost to walk that field. Any number bigger than 0 describes the weight of a field that can be walked on. Any value smaller or equal to 0 describes an obstacle. Import the required libraries: from _movement import DiagonalMovement from import Grid from _star import AStarFinderĬreate a map using a 2D-list. This library is provided by pypi, so you can just install the current stable version using pip: pip install pathfindingĪ simple usage example to find a path using A*. Pathfinding algorithms for python 2 and 3.Ĭurrently there are 7 path-finders bundled in this library, namely:ĭijkstra and A* take the weight of the fields on the map into account. ![]()
