If you have waypoint nodes in your level you can use the A* algorithm A* (wikipedia) If you're not a programmer you should search if someone already wrote an A*-algorithm for Unity or try it yourself.
A* works for almost every pathfinding problem in 2D tiled maps or in 3D maps with nodes. good luck
