How to Get Rid of Sticky Walls in Unity
By Leila Mikhaleva · Game Designer · Digital Artist
Solution Overview
A common issue in 2D Unity game development: characters unintentionally adhere to wall surfaces during gameplay. Here’s the quick fix — a Physics Material 2D with zero friction, dragged onto the player Rigidbody 2D.
Hitting this before you’ve even given your sprite collision geometry? Start with Adding a 2D Collider to Sprites in Unity, then come back.
Step-by-Step Instructions
Step 1: Create Physics Material 2D
Right-click on the Assets section (or in any folder) and navigate to Create → 2D → Physics Material 2D.
Step 2: Configure Friction Settings
Name your new material — the example uses slide. In the right panel, find the Friction value and set it to 0.
Step 3: Apply Material to Player
Select your player character and find its Rigidbody 2D component. Locate the Material field and drag your newly created Physics Material 2D into it.
Step 4: Test
And it’s done. Your character should no longer stick to walls when you run the game.
