Raycast with wrapped screen

Hello,
In my game my screen is wrapped, so every object that crosses right border appears on the left and if it crosses top border it appears on the bottom. I want raycast of limited range from player position also follow that rule. Any help is appreciated!

 

Seems like you would need to have a method that you use instead of directly calling raycasts. That method would look at the raycast origin, direction, and distance and determine if the resulting ray will cross the left or right boundry. If so, it creates a second ray on the opposite boundary with the same direction and distance equal to the remaining distance. It would then combine all the hits and return them as a single list.

Haven't tested this but it seems like it would work.
