mirrors
have mirror so u can direct lasers beams so they can turn round. there would be 4 mirrors so a laser beam can turn a corner. the length of the beam stays the same (including the mirror block as another block in the block length) unless u use a mirror charger which would a glass block with a mirror effect and a red light on it. if there is a laser going into it from any direction it will come out the other side and the light would turn green. from where the laser is placed there would be another 20 blocks of laser beam (which can also change direction). as the laser passes through the charger it would be not seen since it goes through the hole in the block.
because people would just buy 1 laser beam and lots of chargers, the chargers would have to be 10plat since it would also be a spike essentially. when the green light is on it also turns eletrified so if you touch it you die. the beam cant teleport and because the charger is worth 2 more turrets it would be worse because you can only lace it in 1 line (not in separate places) that is why the charger would have a spike effect. it would go in the traps section in a new folder called laser beam add-ons. the mirrors to stop people getting angry would be 1k gold. laser rifles would also work with the mirror and charger just it would deactivate pretty quick
