What does obstacle avoidance enable NavMesh Agents to do?

Obstacle avoidance allows NavMesh Agents to navigate around other objects in the game environment, including other agents and static level geometry. This feature is crucial for creating realistic movement and behavior in a game, as it enables agents to adjust their paths in real-time to prevent collisions. When an agent approaches an obstacle, the obstacle avoidance system contributes to calculating a new path that circumvents the obstacle, allowing for smoother, more natural interactions within the game world.

The other options do not pertain to the primary function of obstacle avoidance. For instance, while dynamic lighting can affect the visibility and atmosphere in a game, it is not related to physical navigation and collision handling. Optimizing rendering focuses on improving visual performance and frame rates, which is separate from agent navigation capabilities. Lastly, improving AI decision-making involves higher-level logic and reasoning, rather than the physical navigational adjustments handled by obstacle avoidance mechanics. Thus, the essence of what obstacle avoidance achieves is best captured by its ability to facilitate collision avoidance for NavMesh Agents within the game environment.
