# init(texture:size:) Creates a physics body from the contents of a texture. ``` init(texture: SKTexture, size: CGSize) ``` ## Parameters `texture` The texture to convert into a physics body. `size` The size of the physics body to return. ## Return Value A new volume-based physics body. ## Discussion Use this method when your sprite has a shape that you want replicated in its physics body. The texture is scaled to the new size and then analyzed. A new physics body is created that includes all of the texels in the texture that have a nonzero alpha value. The shape of this body attempts to strike a good balance between performance and accuracy. For example, fine details may be ignored if keeping them would cause a significant performance penalty. --- Copyright © 2026 Apple Inc.
