In this tutorial Chili shows us an example of how to create a class for an animated sprite, and how to use a collection of these animated sprites to create a walking character class.

Topics Covered

  • Animated sprite class design
  • Walking character class design


The technique we use of storing a reference to Surface in each Animation object will work for now, but it will cause us a pain in the dick in the future when we start using our characters in containers like std::vector. The reason for this is because you cannot assign a reference to refer something else after it has been bound, and so the compiler cannot generate copy assign for us by default. We will fix this problem when it becomes an issue for us (in the Action RPG Project).
