Question 2D building game character bumps in even surface / sticks to walls

I'm trying to make a 2D game, Terraria / Starbound like, as main concept. But I don't seem to get the right character controller at all. If I go with Rigid bodies (which seems optimal), my character bumps going on a straight line, even if the tiles are perfectly aligned (picture).
To solve this someone suggested using composites, but it didn't let me destroy tiles anymore like that (I'm using a raycast, and if it hits a tile, destroy that tile. For building I clamp coordinates to integer based on mouse world position < is this even the right way to go?). Also, if you hold left or right key towards a wall, you stick to it. Tried the 2d physic material with 0 friction everywhere. Still sticks.. Any solution? Thank you so much in advance


I have also tried 4-5 different controllers, including the Brackeys one where it uses 2 collider boxes.

 

I tried going without physics. Works well, but when I jump and I hit a ceiling, it keeps flying for a few seconds. Since it's pushing up.. I rather going with rigidbody.

 

Have you tried using a capsule collider on your player? The rounder edges tends to help.

 

It may be helpful to have a Composite Collider. What is happening is that there's a tiny edge that your square is getting snagged on.

Add Composite Collider component and turn on "Used by composite" checkbox on TilemapCollider2D.

This combines your colliders into one smooth surface, which is less likely to result in snagging.

 

Yes, I have tried. The player keeps bumping in the same way

Thank you for the video. Indeed, I did it in this way already. It removes the bumping, but if I do that I'm not able to destroy the tiles anymore, since now all of them create a new single shape. I would like to treat each tile individually so they can be destroyed. At least, my raycast with destroy(gameObject) stops working with the composite

 

So composite collider work but then destroying does not work? How about trying to destroy the tiles through the tilemap, use a raycast, get the position of the tile, get the tilemap.setTile(position, null); might work?

 

Composite collider works to solve the bumping issue, since now it's an even surface. What doesn't work is destroying tiles with this little system I made

Code (CSharp):

1.  RaycastHit2D rayHit = Physics2D.GetRayIntersection(Camera.main.ScreenPointToRay(Input.mousePosition));
2.  
3.  
4.          
5.             if (rayHit.collider != null && rayHit.collider.name != "player")
6.             {
7.          
8.                
9.                     Destroy(rayHit.transform.gameObject);
10.                 }
11.  
12.             }
13.  

I'm going to try with your solution. I will have to make some changes, since I'm not working with tilemaps!
