Ever wondered how guards in stealth games spot you? � Here’s a breakdown from a game dev perspective!

The cone of vision is essentially a raycasting system that constantly checks for collision points. Key details:

If the raycast hits an obstacle (like a wall), the guard won’t see you.
If the ray reaches the player without obstruction, it triggers a state machine that moves the guard from idle/patrol to alert mode.
In alert mode, the guard’s patrol routes change, and their cone of vision expands, making hiding even harder.
Once the alert timer runs out, they return to their default state. All this is powered by simple AI logic, combining cone vision, collision detection, and behavior states.
