Raycast with overrides will cause the specified raycast gizmo to fire a data-gathering beam from an origin position, with a given direction. A raycast gizmo must be referenced in the first parameter, but will fire from the given position and direction. The data gathered by the raycast can then be extracted with the get raycast data.

Imagine this script attached to an aiming scope, when the event aim is received, raycast causes ray1 to fire a beam in its direction. If the get raycast data registers a hit, then the event fire is sent back to self, passing in a parameter containing the hit position. When fire is received, a second raycast gizmo, ray2, fires from its position directly at the positional coordinates that were passed in.
