Player control of a 2D GameObject (and limiting the movement within a rectangle)

While the rest of the recipes in this chapter are demonstrated in 3D projects, basic character movement in 2D and also limiting the movement to a bounding rectangle, are core skills for many 2D games, and so this first recipe illustrates how to achieve these features for a 2D game.

Since in Chapter 3, Inventory UIs, we already created a basic 2D game, we'll adapt this game to restrict the movement to a bounding rectangle:

Getting ready

This recipe builds on a simple 2D game called the Simple2DGame_SpaceGirl mini game from the first recipe of Chapter 3, Inventory UIs. Start with a copy of this game, or use the provided completed recipe...
