2D Blend Spaces

In Chapter 2, Working with Unreal Engine, we created a 1D Blend Space to blend between the movement states (idle, walk, and run) of a character based on the value of the Speed axis. For that specific example, it worked pretty well because you only needed one axis, but if we wanted the character to also be able to strafe, then we couldn't really do that.

To explore that case, Unreal Engine allows you to create 2D Blend Spaces. The concepts are almost exactly the same; the only difference is that you have an extra axis for animations, so you can blend between them not only horizontally, but also vertically.

Exercise 16.04: Creating a Movement 2D Blend Space

In this exercise, we're going to create a Blend Space that uses two axes instead of one. The vertical axis will be Speed, which will be between 0 and 800. The horizontal axis will be Direction, which represents the relative angle (-180 to 180) between the velocity and the rotation/forward vector...
