Spaceships
- [Man] Here's a naive implementation of a simplified SpaceShip class. You can follow along with me by opening the playground project from the exercise files folder, chapter eight, eight two, begin. Each SpaceShip has a mesh of polygons that describe it's geometry. It also has a texture that makes it look realistic and a position provided as coordinates in the 3D space. Note that normally, we'd use syncing to create 3D entities. I am only using this example to illustrate the problems solved by the private pattern. The following snippet creates one thousand starships. The mesh and the texture can be quite large for a detailed model. Creating a fleet might cause all sorts of problems including memory issues and low performance. If the mesh data is 100 kilobytes in size and the texture is, say, 200 kilobytes, creating one thousand spaceship instances would require more than 300 megabytes of memory. We can do better than that. Let's apply the private pattern. First, we need to identify…
