2D Navmesh sprite and mesh renderer

Hi guys

trying to get my 2d astronaut walking on a platform

Nav mesh work using mesh renderers and i have a sprite. I cant add my object in navmesh for the character to walk on. If i try to add a mesh renderer to my sprite i get an error. "cant add mesh reneder as it conflicts with sprite renderer component."

So i removed the sprite renderer and added a mesh renderer but i cant see any place to put a image.

I then saw that you need a mesh filter and a mesh renderer to work
so i added both, but still cant see where to manipulate graphics.

is mesh only for models? how can i accomplish what i need to?

 

Here is a 'quick-and-dirty' tutorial on how to get NavMesh working for 2D RPG games:

This isn't a full tutorial though. I recorded this for my own personal documentation purposes.

Is your game a sidescroller, or is it a top-down RPG?

 

Hi @warrenbrandt

https://github.com/h8man/NavMeshPlus is a great tool to work 2D navigation. It support NavMEsh building from Tilamap, Sprite or Collider2d. Check out wiki for tutorial https://github.com/h8man/NavMeshPlus/wiki/HOW-TO

Or … is it side view platformer or top-down RPG?

 

Thanks guys very helpful

its side view lunar lander type game

im trying to now have a passenger stand and then walk around, then come to you once you have landed, similar to how choplifter NPCs work...did you ever play choplifter in the 80s?

Also how do you use that package?

will it stop unity building my android project, its what im finding so many assets from the store cause problems with android builds.


thats a fantastic idea to keep track of doing things, think im going to start making my own tutorials too, please share as many as you can with me...please!

 

@warrenbrandt

I know choplifter, but in that game ground is completely flat and does not require NavMesh system at all.
Most side-view and 3d navigation games just use physics raycast for navigation.

So just ray csat your chopper/lunar module to see is it reachable, or better, compare Y values first, and than ray cast for obstacles. Also you can use Observer pattern to just notify about landing. Hard to tell what exactly you want to achieve.

System for platformers can look like this

 

im just trying to get the npc to walk left and right using rays,

but im battling, he just keeps walking right and not turning around

here is the script

Code (CSharp):

1.  
2. using System.Collections;
3. using System.Collections.Generic;
4. using UnityEngine;
5.  
6. public class LeftRightPatrol : MonoBehaviour
7. {
8.     public float speed;
9.     //public float distance;
10.  
11.     private bool movingRight = true;
12.  
13.     public Transform groundDetection;
14.  
15.     private void Update()
16.     {
17.         transform.Translate(Vector2.right * speed * Time.deltaTime);
18.  
19.         RaycastHit2D groundInfo = Physics2D.Raycast(groundDetection.position, Vector2.down, 2f);
20.         if (groundInfo.collider == false)
21.         {
22.             if (movingRight == true)
23.             {
24.                 transform.eulerAngles = new Vector3(0, -180, 0);
25.                 movingRight = false;
26.             }
27.             else
28.             {
29.                 transform.eulerAngles = new Vector3(0, 0, 0);
30.                 movingRight = true;
31.             }
32.         }
33.     }
34. }

 

got it sorted, had to be a platform, need to make it along the ground? but how?

 

heres a bit of a demo
the end is a bit heavy, def 12pg lol

 

It depends what are you trying to achieve. You can create "wanderer" script that will accept waypoint (empty gameobject) and radius on how far you can go. So, walk to the right\left till you exceed distance from way point, or edge of a platform.

The videos I create does not have many use cases and aren't full-featured. However, if you want tutorials that are short, to the point and easy to understand then I suggest checking out Brackeys. He has loads of tutorials and also creates tutorials on request (depending on how much popularity that request has).

yes i know mr smiley Brackeys, very good, thanks!!!
