# generate(staticFriction:dynamicFriction:restitution:)

Creates a new material with the specified static friction, dynamic friction, and restitution.

## Declaration

```swift
@MainActor @preconcurrency static func generate(staticFriction: Float, dynamicFriction: Float, restitution: Float) -> PhysicsMaterialResource
```

## Parameters

- `staticFriction`: The static (stationary) friction coefficient in the range [0, ∞).
- `dynamicFriction`: The dynamic (moving) friction coefficient in the range [0, ∞).
- `restitution`: The coefficient of restitution (bounciness) in the range [0, 1].
