Zig zag stairs


Zig-Zag Stairs


Zig-Zag Stairs

Control platform diagramZIG-ZAG STAIRS:
(Editors Note: In the tutorial map you have just climbed the zig zag stairs - gls) Did you notice that the platforms (other than the ones at each end) moved by two different amounts, depending on which end of the stairs was being raised? That effect required two separate control platforms for each of those platforms, with different active times.

Here's a diagram of how the stairs were built. Arrows indicate control of one platform by another platform or by a switch: numbers indicate the amount of vertical motion of the control platforms (and therefore also the visible platforms adjacent to them).

 

Here are some general guidelines for building puzzles of this sort:

  • The control platforms should have the following flags set: Deactivates At Each Level, Can't Deactivate Externally, Activates Adjacent On Activating, Deactivates Adjacent On Deactivating.
  • The controlled platforms should have Deactivates Never set. You might think that this is irrelevant, since deactivation is actually controlled by another platform, but it does make a slight difference in the distance the platform moves. I can't explain this, but I will point out that I couldn't get any of the puzzles based on platform control to work just right without the Deactivates Never flag.
  • Both control and controlled platforms should move at the same speed. This makes setting the control platform's min/max heights very easy: just make their difference equal to the distance you want the controlled platform to move.
  • To hide the control platforms on the automap, double-click on the lines separating them from visible areas. Check 'Solid' and uncheck 'Transparent'. It also helps to locate them entirely above or below the altitude of the visible areas.
