Well, since the core script is tested, too, i can reveal the project a bit, but without much details. The project is actually the sequel of RLV teleporters (thus 'RTP'.) This technology uses the RLV api to move an avatar gridwide most comfortable (locally is also posible.)
Most important extensions: Predefined target lists to scrol through. Extensible architecture via open APIs. The sensor reacts not only on touch and collision, but also on sit, entering scanned area or chat command.
The core script itself performs only the teleport. Scrolling through targets is matter of the target list script. Its job is delivering the target data inclusive global coordinates to the core script. Next image shows the process map of the target list script.
