How to load multiple LEDs into PPT

[ruddle]

Hey,

I need to set up a simple VR tracking three LEDs, one on the head and two in both hands. Is there loading sequence I have to follow so that these LEDs can be indentified. The following possibilities are my guess:

1. Turn on all the LEDs before running the script, each light at a different height. And initialize them at the beginning of the script based on height.
2. After starting the script, turn them on one by one, for example, from the one with the highest altitude to the lowest.
