How to find specific controllable with Python API

[krtt]

Sim v2021.3 (Linux)

How to find one specific traffic light on a map (we have ~70 in total) if Python API only has the following information (documentation):

For a controllable object of interest, you can get following information:

signal = controllables[0]
print("Type:", signal.type)
print("Transform:", signal.transform)
print("Current state:", signal.current_state)
print("Valid actions:", signal.valid_actions)

But if I want to see in VSE where is the traffic light of my interest, then there is only this info per controllable:

{"uid":"310e0042-66ad-4f60-8029-66e6b54d6e47","policy":[],"spawned":false}

How to connect what is what if one has only transform and other only uid?
Unity did not help to connect them either. How do you do it?

We connect them by noting the position of the map signal controllable. We compare the transform data.

From python api quick scripts 27-control-trafficlights.py

# # Get a list of controllable objects
controllables = sim.get_controllables("signal")
print("\n# List of controllable objects in {} scene:".format(lgsvl.wise.DefaultAssets.map_borregasave))
for c in controllables:
    print(c)

signal = sim.get_controllable(lgsvl.Vector(15.5, 4.7, -23.9), "signal")
print("\n# Signal of interest:")
print(signal)

Having 70+ map signals in a single map worries me that your map is too large. It's best to take map sections and test very specific use case test for small areas instead of a large map. You can have issues with memory with a large map.
