Explaining Line of Sight in Games
Discover what Line of Sight (LoS) is, how it impacts stealth and combat, and why it's a core mechanic in modern strategy and shooter games.
What is it?
In video games, Line of Sight (LoS) is an unobstructed visual path between two points, typically a player's character and an NPC, enemy, or object. It's a fundamental mechanic that determines what a character can see and, consequently, interact with or target. If the path is blocked by a wall, smoke, or other obstacle, LoS is broken. This concept is crucial in numerous genres, from first-person shooters where you need LoS to shoot a target, to stealth games where you must avoid an enemy's LoS, and strategy games where it dictates unit visibility and fog of war.
Why is it trending?
Line of Sight is a timeless mechanic, but its sophistication is constantly evolving. Modern games feature more dynamic and realistic LoS systems. Advanced AI now uses complex LoS calculations, including peripheral vision and sound cues, to create more challenging stealth and combat scenarios. In the competitive esports scene, particularly in tactical shooters like Valorant or CS:GO, mastering and manipulating sightlines is the difference between winning and losing. The rise of destructible environments also means that lines of sight are no longer static, adding another layer of strategy.
How does it affect people?
LoS directly shapes the player experience by forcing tactical thinking. It encourages players to be constantly aware of their positioning, use cover effectively, and control the battlefield's visibility. In stealth games, the tension of staying out of an enemy's cone of vision is a core part of the thrill. For action and shooter fans, LoS dictates the flow of combat, creating a constant dance of seeking clear shots while denying them to the enemy. Ultimately, it empowers players by giving them control over information and awareness, making gameplay feel more strategic and rewarding.
