To use teleport traps, first place
the teleport trap itself where you want the object to be teleported
to (the size of the trap itself doesn't matter, only the co-ordinates).
Then, create a switchlink
between the trap to the item you wish to be teleported into
it (for example, some item inside a so-called "Blue Room" which
you want to appear inside your level "out of nowhere", which
is actually "out-of-where-the-player- could-know-you-are-hiding-that-object")
The final step is to create a switchlink (a hacklink might work;
I haven't checked this yet), from a controller, another trap
etc to the Teleport Trap.
Once you activate that, the item is immidiately teleported to
the teleport trap's location.
Destroy Traps works similarly, except for the fact that they
destroy their "target" (i.e. the item which has a switchlink
FROM the destroy trap).
Useful for removing force-fields and such (for example, look
at the usable computer at the crew quarters of the original
shock 2 Medsci level.
On sucessful hacking it activates (via a Hacklink) a destroytrap
which destroyes (via a switchlink) the force door which blocks
you from entering that closet).
