[Solved] Character gets stuck in floor

Hi,

I'm creating a small 2D platformer as a first project.
I applied a Material with 0 friction to my character so he won't stuck on walls. That works just fine, but the problem now is that he stucks in the floor for some reason. I can move a few pixels to the left and right before he randomly stops.
I recorded that:

Thanks in advance

 

box collider for the player and the platform is making from 3 parts ? then try capsule collider

 

Sorry, I don't understand what you mean

 

does your player have boxcollider2d ? In this case try to change the players collider to the capsulecollider2d. I can't see from the video if the collider is the problem.

 

It works just fine with the capsule collider, thank you

 

Thanks it also works well with me

 

if i do this i dont get stuck anymore but my animations stop working, suddenly my jump or fall animation starts playing.
please help

 

Try setting the collider such that the collider's bottom matches with the player's bottom. Similarly for the other sides. It may then work

 

For future reference, this is caused by Ghost Vertices - http://www.iforce2d.net/b2dtut/ghost-vertices

solve this by using curved objects like a capsule or circle for your player instead.

 

using a capsule or circle collides creates another problem, you now slide off the edge, which is fine for 3D, but awful for 2D and fells hella unnatural especially when it kills your jumps when you try to make a running jump at the edge, which is something i can do effortlessly in most platformers

 

What did the fix for me was using a BoxCollider2D with my player and then for my Tile Map I added the TileMapCollider2D and CompositeCollider component. The CompositeCollider will automatically add a RigidBody2D to your Tile Map. Set the RigidBody2D to static. On the TileMapCollider2D, check the box Used By Composite. Instead, of multiple colliders for your tilemap now unity recognizes it as a single collider. Credit to this tutorial:

 

The Capsule collider is the solution to my platform as the blocks of the ground were making the enemies movement stuck after sometime. The player is fine with it's box collider.

 

Now my player cant jump. Wy?

 

I had this same issue... In the youtube video someone commented this, which fixed it for me:

Change the composite collider geometry type from outline to polygon.

For some reason, my character would sink below the outline of the composite collider, and would not jump, would basically get stuck in the floor. For whatever reason, changing to polygon just worked for me. Hope this helps.

 

For anyone in the future:
Try decreasing the Default Contact Offset in Edit/Project Settings/Physics
Changing it from 0.01 to 0.0001 worked for me
