Chapter 3. Character Animations
In this chapter, we will cover the following topics:
• Loading animated meshes in the sandbox
• Attaching meshes to animating bones
• The sandbox soldier and weapon animations
• Blending multiple animations
• Creating a Lua animation state machine
• Building a soldier and weapon animation state machine
With a basic sandbox under our feet and a primitive agent representation, we can now
move on to handling animations so that our agents can finally begin to look human. While
we could assign a basic human mesh to our agents so far, they could never really look hu-
man without animations.
Animations play a key role in not only the visual aspect of the AI, but also the functionality
of the AI. This might seem counter-intuitive, but the sandbox AI can only perform behavi-
ors that the AI has animations for. If an animation takes 5 seconds to play out and can't be
interrupted, our AI needs to take this into account before it decides to execute an anima-
tion; otherwise, our AI loses all reactiveness for these 5 seconds.
