Build Your Game: Vector Actors and Particles
Core Graphics is a powerful 2D drawing library that is responsible for rendering large portions of iOS and OS X. In this chapter, we see how to use this library to draw actors in our game. The goal is to have actors that are drawn dynamically based on game state. To illustrate this, we’ll create two example actors drawn with Core Graphics: a health bar that shows the amount of health remaining for an actor, and a bullet that is drawn in a particular color depending on how powerful it is. These two examples will illustrate how to use Core Graphics within the context of the simple game engine started.
