Unity3d pathfinding function Introduction and project demonstration

Pathfinding in Unity3d, you can use the Astarpath pathfinding plugin. It is now possible to use Unity's own Navigation functionality.

To do an example:

In the above picture, Cube is a block object, the ball is to represent the player, to find the way.

Set cube as a non-pass object

First we click on the Window-navigation window and then select 4 cubes, set these 4 cubes as not to pass, then bake

Set the ground to be passed, and then bake

We add control scripts to the Orb, our main character.

Using unityengine;using System.collections;public class Findpath:monobehaviour {public    navmeshagent agent;    Vector3 Point;    Ray Aray;    Raycasthit ahit;//Use the-initializationvoid Start () {}//Update is called once per framevoid update () {if (Input. Getmousebuttondown (0)) {        Aray = Camera.main.ScreenPointToRay (input.mouseposition);        if (Physics.raycast (aray,out ahit))        {point            = Ahit.point;        }        Agent. Setdestination (point);}}}

Get the ball to the mouse click on the place to find the road effect
