Fortunately, there are some tricks that can be used to achieve the 3D effect in a relatively easy way. hitInfo: If true is returned, hitInfo will contain more information about where the closest collider was hit. Raycasting is used by game developers to find the distance between players and another object, aiming, detecting nearby objects, and finding line of sight. Strictly speaking this is inaccurate, since the method of ray tracing with which most people are familiar is more complex than ray casting.
