Move around the star object

Hello guys.
I did not find a solution to my problem, so I write it here.
My problem:
I need a player to move only through the black layer of the star (see screenshoot). It is possible ? Or if I have a polygon for example, I need a player to move only over the black polygon layer.

Thanks for every answer.
Beginner power .

 

Okay.
So the black outline that makes up the star, is like a star shaped path/maze?
So in other words, you can walk in a star shaped path?
But the white areas, are off limits, right?

 

Yes man

 

use an edge collider. you can then add points by double clicking on the green collider outline while youre editting it. i have no idea how to remove the points though xD

you might have to play with the edge radius and positioning so that you cant force your way through

 

I'd do it like this:

Star (Empty Game Object)

Star Sprite (Sprite)​

To the Star Game Object add Two Edge Collider Components.
Increase the Edge Radius a bit depending on how large or small your sprite is. If the edge radius is 0, then your player might move right through it depending on how you choose to move your player around.

Click on the Edit Collider Button and position points on the edge collider in their correct spaces.

This will work if you move player using transform.position, but will be smoother if you use use rigidbody movement such as Rigidbody.AddForce or manipulate rigidbody.velocity directly.

In this example I just manipulated the transform.position for simplicity.
player is just a circle sprite with a circle collider.

for the player I used this script:

Code (CSharp):

1.  
2. using System.Collections;
3. using System.Collections.Generic;
4. using UnityEngine;
5.  
6. public class TransformMove : MonoBehaviour
7. {
8.     [SerializeField]
9.     private float horizontal;
10.     [SerializeField]
11.     private float vertical;
12.  
13.     [SerializeField]
14.     private float speed = 1f;
15.  
16.  
17.  
18.     void Update ()
19.     {
20.         GetInput();
21.  
22.         MovePlayer();
23.     }
24.  
25.     private void GetInput ()
26.     {
27.         horizontal = Input.GetAxis("Horizontal");
28.         vertical = Input.GetAxis("Vertical");
29.     }
30.  
31.     private void MovePlayer ()
32.     {
33.         Vector3 newPosition = transform.position;
34.  
35.         newPosition.x += horizontal * speed * Time.deltaTime;
36.         newPosition.y += vertical * speed * Time.deltaTime;
37.                
38.         transform.position = newPosition;
39.     }
40. }
41.  

 

You can delete a point by Control Clicking on the point you wish you remove.

 

Thank you guys
