# Player keeps bumping when walking over to another sprite

So, my problem is that my play when he walks over to another sprite he will stop.

I fixed that by adding a physics material with 0 density and 0 friction to the player

and adding a circle collider instead of a box collider to the player.

However now I have another problem where my character keeps bumping when it enters another sprite.

The sprites are at the exact same height, the objects are just as big and the colliders have the exact size.

I would like to get a fix for this problem, which still allows me to use Rigidbody2D.AddForce for movement.

Video of my problem :

How to recreate the problem :

Make a sprite, add a Circle Collider 2D to it and a Rigidbody2D.

That will be the player.

Next, make some platforms and add a Box Collider 2D

Now, if you let your player walk over the platforms it will (or should..) start bumping.

• I saw your video, but can't replicate the problem. If you have an online repo of your project, I could download it and start it up in Unity. – user79422 Feb 20 '16 at 20:41
• @codeepic This happens all the time to me, here's what I do to create my problem : Create a 2D circle collider and attach it to a sprite GameObject with a rigidbody2D, add 3 sprites to your scene, all 3 should have 2D box colliders, make the player walk over them using AddForce, and it should start bumping when the player "crosses" a sprite. Hopefully this made sense. – BiiX Feb 21 '16 at 1:17
• I'm having the same issue. Plus my design requires some of the object to have box colliders. I am very interested if someone found a real solution that still uses Unity's rigidbodies – tyjkenn Feb 21 '16 at 23:43
• I can see a box collider too on player, larger in height, is it so or I am just confused? – Hamza Hasan Feb 23 '16 at 5:40
• If it is so, then that is the only problem – Hamza Hasan Feb 23 '16 at 5:50
