Portal Spawner



Portal Spawners, also known as Portal Emitters, Portal Doors, or Autoportals are test mechanics that appear in Portal and Portal 2's single-player campaign.

Overview
When activated, a Portal Spawner will spawn a portal inside of it. Each spawner is set to spawn a particular color portal. Spawners are sometimes activated as soon as you enter the test chamber. Other times, they are activated by Pedestal Buttons or set on a timer. In the very beginning of each game, when the player has no Handheld Portal Device, both blue and orange Portal Spawners can be found in the test chambers. Once the player has the Single Portal Device and can fire blue portals on their own, only orange Portal Spawners appear. When they have the Dual Portal Device, Portal Spawners disappear altogether.
