A* Pathfinding Algorithm Java Implementation
The A Star Class : import java.util.ArrayList; public class astar { // grid [y-coordinate][x-coordinate] public static void main(String[] args) { // Map to be traversed : int y = 5, x = 5; node[][] grid = new node[y][x]; // Populate grid (Otherwise the grid will contain NULL values) : // Set x and y values : for (int i = 0; i < y; i++) for (int j = 0; j < x; j++) grid[i][j] = new node(i, j); // Add walls : grid[1][1].setWalkable(false); grid[2][2].setWalkable(false); ...
