Detailed Description

Make an actor follow a target entity in the world.

System Parameters

<target>: Name of entity to follow.
<min_distance>: Distance in meters to keep from target's origin.
<max_distance>: Distance in meters from target's origin when to stop following. When the actor is back within range it starts following again.
<velocity>: Actor's velocity in m/s
<animation>: Actor's animation to play. If empty, the first animation in the model will be used.
<animation_x_vel>: Velocity of the animation on the X axis. Used to coordinate translational motion with the actor's animation.
