Enable Vision For All NPCs in UDL

Hi folks, apologies if this has been covered elsewhere but is there a method of enabling vision for all monsters/npcs? This post by the ever helpful keithcurtis, referencing a script by The Aaron, is exactly what I'm after but I assume this no longer works due to 'has sight' relating to LDL. Cheers

Hi Rotimer! Here's a UDL-friendly version , again, courtesy of the amazing Aaron.

Fantastic. Most kind of you. You both have just saved me a whole heap o' clicking. Cheers

Oh dear, sorry to be a pain. While the script does work correctly and enabled vision for all NPCs when I issued the command, it merely flips the Vision toggle but the vision doesn't work. Roll20 obviously recognises that the token has vision as pressing Ctrl+L before using the script results in the pop up saying the token does not have vision enabled. However unless I open the token settings and manually toggle the Vision off and then on again, the token sees no light. Here's a gif demonstrating the behaviour I experienced this same behaviour when I was trying to use TokenMod to enable vision.

Apologies for the bump, if it's poor etiquette here I'm happy to start a new thread. Has anyone any insight as to why the Vision toggle doesn't actually enable vision when set via API?

There is a bug that a token does not respect Angle of Light when set by the API until the token is opened and closed manually, but vision should work. It does for token-mod (just tested). It's possible the Aaron put in some code to work around that bug. I'll see if I can ping him.

Ah, so that's what's happening. Thanks again.  And you only need to open and close the token, you don't need to toggle the vision manually like I initially thought. That's not so bad. Obviously if The Aaron had some cunning code that saves the extra clicksI'd be delighted to use it, but I can live with it if not.
