ChaseTrait
constChaseTrait:Trait<{reach:number;reached:Entity|null;speed:number;walks:boolean; }>
Moves toward the nearest player’s character at speed, stopping reach away: along
the world’s navmesh, or through the walk a player’s walker runs where
walks asks for it or the world has no navmesh. reached holds the
character within reach, or null: the step emits ChaseReachedEvent and
ChaseExitedEvent on the step it changes.
