Chapter 7. Creating a third-person 3D game: player movement and animation
This chapter covers
- Adding real-time shadows to the scene
- Making the camera orbit around its target
- Changing rotation smoothly using the Lerp algorithm
- Handling ground detection for jumping, ledges, and slopes
- Applying and controlling animation for a lifelike character
In this chapter you’ll create another 3D game, but this time you’ll be working in a new game genre. If you think back to chapter 2, you built a movement demo for a first-person game. Now you’re going to write another movement demo, but this time it’ll involve third-person movement. The most important difference is the placement of the camera relative to the player: a player sees through their character’s eyes in first-person view, and the camera is placed outside the character in third-person view. This view is probably familiar to you from adventure games, like the long-lived Legend of Zelda series, or the more recent Uncharted series of games (refer ahead to figure 7.3 if you want to see a comparison of first-person and third-person views).
The project in this chapter is one of the more visually exciting prototypes we’ll build in this book. Figure 7.1 shows how the scene will be constructed. Compare this with the diagram (figure 2.2) of the first-person scene we created in chapter 2.
