Sphere shape resource for 3D collisions. 3D sphere shape to be added as a [i]direct[/i] child of a [PhysicsBody3D] or [Area3D] using a [CollisionShape3D] node. This shape is useful for modeling sphere-like 3D objects. [b]Performance:[/b] Being a primitive collision shape, [SphereShape3D] is the fastest collision shape to check collisions against, as it only requires a distance check with the shape's origin. https://godotengine.org/asset-library/asset/675 The sphere's radius. The shape's diameter is double the radius.
