Thermal discouragement beams are a game mechanic in Portal 2 which can be thought of as lasers. A typical thermal discouragement beam puzzle in portal involves redirecting a laser into a socket using portals, redirection cubes, or a combination of the two. When the player touches a laser in Portal 2, they receive a small amount of damage and are pushed away from the beam (that is, they are thermally discouraged). If the player continues to run into the beam they will eventually die. Turrets die almost as soon as the laser touches them.
'''Thermal discouragement beams''' or '''lasers''' are a puzzle element in [[Portal 2]]. Lasers emanate from emitters, and can be used to trigger sockets and destroy things, mainly [[turret (Portal 2)|turrets]]. They can be extended with [[Portal (Portal 2)|portals]], just like [[bridge (Portal 2)|bridges]], [[wall (Portal 2)|walls]], and [[Excursion Funnel|funnels]]. When players touch a laser, they receive a small amount of damage and are pushed away from the beam. Prolonged contact will kill the player.

Thermal discouragement beams or lasers are a puzzle element in Portal 2. Lasers emanate from emitters, and can be used to trigger sockets and destroy things, mainly turrets. They can be extended with portals, just like bridges, walls, and funnels. When players touch a laser, they receive a small amount of damage and are pushed away from the beam. Prolonged contact will kill the player.

Creation

The two most important elements of any laser setup are env_portal_laser and prop_laser_catcher, which create and "catch" the laser, respectively. Two optional elements are the prop_weighted_cube with CubeType set to 2 (redirection cube) and the prop_laser_relay.
