Unstationary Scaffold: Difference between revisions

In the [[Portal developer commentary #.23043|developer commentary]] of ''Portal'', players learn that originally, the scaffold moved along a solid track, but playtesters found that they could cheat a level by walking along the track. Then, the developers made the rail 'electrified', so that contact with it would kill the player. This seemed harsh to playtesters, and made use of the scaffolds more difficult, as a slight slip could kill the player. The developers then moved on to the current design, where the scaffold is supported on a beam of light that will not kill the player on touch.
