Portal Gun

Remember mod "GraviPuška" that I put? It's much cooler!
You can create a portal-log in one place, and portal-exit to another and thus do crazy stunts on cars and motorcycles, scoff at police and passers-by, create chaos and disorder in the streets, or just have fun!
And now about managing:
-Enter the cheat code PORTAL
-then to create the "sign in" click the right mouse button (sight), then the left button of the mouse (fire)
-to make an "exit" click the right mouse button (sight), and then press the mouse wheel
-go to "login" and you will find yourself at the "going out"
-in order to avoid deadlocks, do not make two portal number

See the video and all will understand:
