Does the "One-Way Dynamic Lighting" still work?

newer to all the API and macro stuff and dnd on roll20 as well, just started a campaign 2 weeks ago and we've had them weekly on Sundays, never had to deal with height because most of it was just forest and cave fights, but now that I want to add cliff fights (And I put 10 bucks into a pro subscription)  so id like to do some 1-way vision rock climbing things and let my players be like (I just climbed a mountain look at my friends down there lol) so ive a been trying to make OWDL work but I'm probably just not using it right. also I looked at the gif and I'm kinda dumb so I'm not sure if I did it right and I tried it to the exact T so some help would be very much appreciated

The One-Way Dynamic Lighting script doesn't create true one-way dynamic lighting, because unfortunately it isn't really possible right now.  All it does is move dynamic lighting lines to the GM layer when a token is in a specific area.  So when a token moves into that area, the lines are removed from the DL layer, and everyone  can see through where the lines were. If you want to simulate one-way dynamic lighting, another approach is to use a transparent .png token with vision enabled that the player controls, and when a player moves into an area that should be able to see 'more', place the transparent token on the other side  of the DL lines. There is likely a way to automate that with a script, but I don't know of any that would do that already.  The 'It's a Trap' and 'Spawn' scripts can both make tokens appear, but they wouldn't automatically be controlled by the player moving their token into that area or be given vision abilities.

Can you post the error you're getting?  Are you installing the script in the API Scripts tab, not pasting it in the chat or elsewhere?

FYI note that the Spawn script can set the controlledby property of the character sheet represented by the token spawned. You would set up the default token to have vision. --controlledby| <optional +> <comma-delimited list of playerIDs or displayNames>   e.g.  --controlledby|David M.                          //replaces the controlledby property of the sheet with player David M. --controlledby|+David M., Bubba            //adds these two players to the controlledby property of the sheet

I use this script probably a lil different than intended, I call this script Vantage point API and anything in a battlemap that the players might be considered to climb up or onto, I use this script on.
