Agent-steering forces
With some basic agent properties and a full-fledged physics system supporting the sand-
box, we can begin moving agents realistically through forces. This type of movement sys-
tem is best known as a steering-based locomotion system. Craig Reynolds'
Steering Beha-
viors For Autonomous Characters
(

) is best known for describing this style of steering system for moving char-
acters. Steering forces allow for an easy classification of different movement types and al-
low for an easy way to apply multiple forces to a character.
As the sandbox uses the OpenSteer library to steer calculations, this makes it painless for
Lua to request steering forces. While the steering calculations are left to OpenSteer, the ap-
plication of forces will reside within our Lua Scripts.
