# generateStaticMesh(from:)

Creates a static collision mesh from a mesh resource.

## Declaration

```swift
@MainActor @preconcurrency static func generateStaticMesh(from mesh: MeshResource) async throws -> ShapeResource
```

## Parameters

- `mesh`: The mesh resource for generating the collision shape.

## Discussion

Discussion You can use only the physics body mode PhysicsBodyMode.static and the collision component mode CollisionComponent.Mode.default with this shape. The code example below assumes calling this method from a synchronous block: // Use a low-priority task because generating collision meshes can take a while. let myShapeTask = Task(priority: .low) {     let meshResource = await MeshResource(         shape: .generateBox(size: [5, 5, 5])     )

guard let shape = try? await ShapeResource.generateStaticMesh(         from: meshResource     ) else { return }

// You can use the `ShapeResource` to make a     // `CollisionComponent`, and add that to an entity.     // Run this from the main thread.     await MainActor.run {         let entity = Entity()         let collision = CollisionComponent(shapes: [shape])         entity.components.set(collision)

// Note that you can't set `mode` to `.dynamic`.         // This only supports `.static`.         let physicsBody = PhysicsBodyComponent(             massProperties: .default,             material: nil,             mode: .static         )         entity.components.set(physicsBody)         // ...     } }
