NOW we're thinking with Portals.

This zip file includes 8 images: the Portals, in Red, Orange, Yellow, Green, Blue, Indigo, and Violet, and a 1x1 black dot called "blank".
These texture files (excluding "blank") are intended for use on cbloopy's Generic Rectangle object, or, for wall portals, the Generic Square, in this thread.
How do the portals work? Using XAdjust, YAdjust, Pitch, Roll, and Yaw, the Square should appear in front of a teleporter with the blank texture applied.
Have the Teleporter's activationspeed at its highest, 40. This creates a one-way portal.
To have one that works more than once, surround the teleporter with a General Command button, set to CMD 1 and the Data1 to the Teleporters colour ID number.
There's also a test adventure for those who don't understand (NOTE: The walls between the last two portals are floor tiles, way to go me)
Download and extract the files into WA Editor v96/Custom.
