Platformer 2D w/ tilemap: Move player with moving-platform.

I know how to make the player move with a moving-platform by making it a child of the platform:



But my problem is that the player has a capsule collider and a zero-friction-physics2d-material applied (to prevent getting stuck in walls from the tilemap like this guy: https://forum.unity.com/attachments/screen_problem-png.143501/ ).
However that zero-friction-physics2d-material also causes the player not to move along with the moving-platform (took me a week to figure out that this was the cause). Applying a material with friction to the platform obviously does not fix it because zero multiplied by something is still zero.

Yes applying a friction material to the player obviously solves the moving-platform issue but then I get stuck in every wall from the tilemap again.

How do I best solve this?

 

Hi I'm not sure how you would implement this but I'm sure you can apply a different material upon OnCollisionEnter with the platform and then change it back with OnCollisionExit. Just a thought

 

Wow thanks that super simple solution does indeed work (why did I not think of that..). I however cannot drag a Physics2DMaterial into the inspector onto a public variable for some reason but I can make them strings and load it in the Start() function and since enemies require it as well I made a separate Script:

Code (CSharp):

1. using UnityEngine;
2.  
3. public class PlatformEntity : MonoBehaviour
4. {
5.     public string DefaultMaterial = "PM_Default";
6.     public string PlatformMaterial = "PM_Platform";
7.  
8.     PhysicsMaterial2D MaterialDefault;
9.     PhysicsMaterial2D MaterialPlatform;
10.     Collider2D Collider;
11.  
12.     void Start()
13.     {
14.         Collider = GetComponent<Collider2D>();
15.         MaterialDefault = Resources.Load("Materials/" + DefaultMaterial, typeof(PhysicsMaterial2D)) as PhysicsMaterial2D;
16.         MaterialPlatform = Resources.Load("Materials/" + PlatformMaterial, typeof(PhysicsMaterial2D)) as PhysicsMaterial2D;
17.     }
18.  
19.     public void SetMaterialDefault()
20.     {
21.         Collider.sharedMaterial = MaterialDefault;
22.     }
23.  
24.     public void SetMaterialPlatform()
25.     {
26.         Collider.sharedMaterial = MaterialPlatform;
27.     }
28. }

And ohyeah I also had to change the platform material itself from 0.4 --> 1.0 friction.

 

Looks good and its always the simple things that catch us out , sometimes you just need to take a break or get someone else to have a look
