[Script] UniversalVTTImporter -- Import .dd2vtt files to create Dynamic Lighting Lines and Lights!

Andan said: ...and of course, after onemore  !uvtt, the new settings showed up. Thanks for the help  The Aaron !

Worked like a charm! I love the RPG community, thanks a bunch for making this public.

No problem!  Glad it's working for you!

I'm very new to game mastering on roll20. I'm confused by the instructions. How do I install this software? Is there a different tool that generates the .dd2vtt file? Sorry, just confused by the instructions and the universal VTT tool doesn't have a readme in the GitHub.

API scripts require a pro subscription. .dd2vtt fires are the export format of Dungeon Draw. 

I have a question does the Script support updated Dynamic Lightning?

Yes, such as it is. It will detect which is in use on the page and set the lighting appropriately for it. 

Hello, this looks cool! However, I am also getting the issue that Malik H. had, the "Error: Universal VTT Data is missing or corrupt" error. I have the graphic selected, used the Universal VTT Import Sanitizer from the Universal VTT file (from Dungeondraft), and pasted the output into GM notes of the graphic selected. I shut off all other API scripts like he did, but still am getting the error. The output is below in the codeblock: {"format":0.2,"resolution":{"map_origin":{"x":0,"y":0},"map_size":{"x":35,"y":30},"pixels_per_grid":70},"line_of_sight":[[{"x":19,"y":23},{"x":23,"y":23},{"x":23,"y":24},{"x":22,"y":24},{"x":22,"y":26},{"x":11,"y":26},{"x":11,"y":25},{"x":12,"y":25},{"x":12,"y":23},{"x":13,"y":23},{"x":13,"y":24},{"x":19,"y":24},{"x":19,"y":23}],[{"x":18,"y":18},{"x":20,"y":18},{"x":20,"y":19},{"x":24,"y":19},{"x":24,"y":18},{"x":25,"y":18},{"x":25,"y":22},{"x":19,"y":22},{"x":19,"y":20},{"x":18,"y":20},{"x":18,"y":18}],[{"x":24,"y":17},{"x":24,"y":12},{"x":28,"y":12},{"x":28,"y":15},{"x":30,"y":15},{"x":30,"y":21},{"x":29,"y":21},{"x":29,"y":22},{"x":26,"y":22},{"x":26,"y":17},{"x":24,"y":17}],[{"x":19,"y":8},{"x":21,"y":8},{"x":21,"y":10},{"x":20,"y":10},{"x":20,"y":17},{"x":17,"y":17},{"x":17,"y":20},{"x":13,"y":20},{"x":13,"y":22},{"x":12,"y":22},{"x":12,"y":21},{"x":7,"y":21},{"x":7,"y":20},{"x":11,"y":20},{"x":11,"y":13},{"x":10,"y":13},{"x":10,"y":9},{"x":11,"y":9},{"x":11,"y":8},{"x":15,"y":8},{"x":15,"y":9},{"x":19,"y":9},{"x":19,"y":8}],[{"x":11,"y":4},{"x":16,"y":4},{"x":16,"y":5},{"x":15,"y":5},{"x":15,"y":6},{"x":11,"y":6},{"x":11,"y":4}],[{"x":30.992188,"y":0},{"x":31,"y":0},{"x":31,"y":2},{"x":33,"y":2},{"x":33,"y":15},{"x":31,"y":15},{"x":31,"y":21},{"x":34,"y":21},{"x":34,"y":25},{"x":29,"y":25},{"x":29,"y":23},{"x":26,"y":23},{"x":26,"y":28},{"x":22,"y":28},{"x":22,"y":27},{"x":10,"y":27},{"x":10,"y":25},{"x":5,"y":25},{"x":5,"y":21},{"x":6,"y":21},{"x":6,"y":20},{"x":2,"y":20},{"x":2,"y":18.027344},{"x":-0.800781,"y":18.027344},{"x":-0.800781,"y":14.984375},{"x":2,"y":14.984375},{"x":2,"y":13},{"x":9,"y":13},{"x":9,"y":9},{"x":6,"y":9},{"x":6,"y":1},{"x":11,"y":1},{"x":11,"y":3},{"x":16,"y":3},{"x":16,"y":1},{"x":22,"y":1},{"x":22,"y":5},{"x":19,"y":5},{"x":19,"y":7},{"x":22,"y":7},{"x":22,"y":10},{"x":24,"y":10},{"x":24,"y":11},{"x":28,"y":11},{"x":28,"y":10},{"x":27,"y":10},{"x":27,"y":2},{"x":29,"y":2},{"x":29,"y":0.957031},{"x":28.992188,"y":0.957031},{"x":28.992188,"y":-1.320313},{"x":30.992188,"y":-1.320313},{"x":30.992188,"y":0}]],"portals":[],"environment":{"baked_lighting":true,"ambient_light":"ffffffff"},"lights":[]} What am I doing wrong, if anything?

I am also getting the " (From ): Error: Universal VTT Data is missing or corrupt." Error...

Hmm. Sorry I didn't get back to you today, it's a super busy week for me. I'll try and take a look tomorrow. 

It worked this time. Not sure why it didn't before, but I was able to get it to go. Once again -- ty for your hard work!!

That's great to hear!  I still need to investigate Caymon's issue, maybe it's working for them now too. 

I'm not understanding how to run the !uvtt. I've tried "/run !uvtt", "/run!uvtt", and just "!uvtt". nothing seems to work.I keep getting "Unrecognized Command". I just started using Dungeondraft and I would love to be able to import them easily. I do have a Pro subscription to Roll20.

Have you installed UniversalVTTImporter from the Script Library on the API Scripts page of your game?

Not that I know of. How do I go about doing that?

Nevermind. I figured it out. Thanks for everything, this makes map making so much easier.

Great!  Let me know if you run into any issues or think of anything that could be added to this.

oh, so we need a Pro account to use this? I bought the plus in order to unlock dynamic light. But I can't because even with dynamic light, if I can't use API script, I can't use it? Did I miss something?

That's correct, sorry for the delay in responding.  The API is a Pro Subscriber Perk.  You can draw Dynamic Lighting lines with a Plus subscription, but you need a Pro subscription to use API scripts.

Hi Aaron the wonderful API!. I think this is likely my lack of understanding but after I run the script my maps end up with circles everywhere? I have attached some screenshots. Happy to provide any further clarification as necessary.

Those are likely the light sources for the map.  If you go to the DL layer, you'll see some green spots where each light source is centered. That said, that highlighted a bug in the way bright and dim light are specified for UDL, which I've now fixed and pushed up.  it should be available in the 1-click Tuesday.  You'll have to select your map and run: !uvtt --clear !uvtt to fix the light sources, or manually edit them, sorry about that.

Update v0.1.7 -- Fixed Bright and Dim Light calculations on UDL. (Thanks  iamonlv426 )

Thanks, Aaron that's brilliant really appreciate your prompt reply. 

Hey Aaron I still haven't seen it appear in the 1-click as yet - how long does it normally take?

Hmm..  Looks like the API pull requests weren't pulled in last week.  I'd expect it to show up tomorrow evening.

Thanks Aaron.

This API script is awesome.  Such a time saver. I'm trying to use it to set the lighting for a multi-level building, and am running into some usability speed bumps.  Since it's using the GM notes to get the coordinate info, I can only store the lighting geometry for one level of the building, and need to save the JSON for the other floors elsewhere.  Clearing the lighting, swapping the JSON out manually, and rerunning the `uvtt` command is workable, but definitely breaks the flow of gameplay. To aid in scripting, could optional arguments be added to the `uvtt` command to specify the lighting geometry and target token object manually? That or a way for it to index into a list of geometries in the GM notes based on the current index in the selected token's rollable table.

hmm.  I'm having a hard time understanding why the GMNotes wouldn't hold all the light info, or alternately why you'd need to overwrite the GMNotes for different graphics?  Can you lay it out lay it out in more detail for me, or perhaps PM me a link to your assets so I can try and duplicate the issue?

I can't get any maps to work with this anymore. In the past, the standard instructions have worked just fine, but even with the API up to date, nothing happens when I run the !uvtt command. Is there anything new that I'm missing?

You have the graphic selected, and you've put the json data in the gm notes on it?

I did. No idea what happened, but I deleted and reinstalled the API again, and it worked this time. Unsure why, but at least it works!

Hmm.  Tuesday is when they do API updates, it may have been that the API sandbox in your game was in a weird state.  Glad you got it working and let me know if you have any more issues. 

Hi @aaron,  first off, I love your scripts.  I installed this one and was able to successfully import all the dynamic lighting for a map in minutes. the instructions were spot on. But. now I tried a second map on a second page and it keeps complaining about missing or corrupt vtt data. I did everything the same... I even tried re-importing the vtt data that worked the first time and it still complains about bad data. Any Ideas? I already tried downgrading to 1.6 and deleted and reinstalled. I restarted the sandbox several times and reuploaded the image too. 

Hmm. That's peculiar. If you want to pm me the file contents, or invite me to your game and GM me, I can take a look. 

Never mind. I figured it out in the end. I've been installing too many extensions! got a bit carried away. After diasbling the conflicting code it all worked as expected. 

Great!

Alex D. said: Never mind. I figured it out in the end. I've been installing too many extensions! got a bit carried away. After diasbling the conflicting code it all worked as expected.  Can you please let us know what the conflicting code was? I am having the same issue and also have a few other scripts and extensions installed, so I'd like to try and narrow it down if possible. Edit: I discovered the solution to the problem. I had not assigned the map token to represent an actual location in the journal, it was just a generic token that I had put down. To solve the issue, I created a 'character' for the map and assigned the map token to it, making sure that the token represented the map, before running the command again. Hopefully this helps anyone who makes the same mistake. 

Hmm. It shouldn't require a token representing a character.  I'll have to look into this. 

For anyone using DungeonFog and their UniversalVTT .df2vtt format, the sanitizer works without issue.

Woot!  That's great news, I didn't even realize they were using this format.

I restarted the sandbox several times and reuploaded the image too.  I'm having this same issue. However, I do not have any other scripts installed and so I'm not sure what could be causing this. Another discrepancy is I am still able to recreate the same map I did the first time (73x25). The one that keeps getting the error is pretty large (75x57) - could that be an issue? Edit: Tried it again with a new, smaller map (25x38) and it worked! I'll keep that in mind as I continue to add on to my ridiculously large dungeon. Edit 2: Folks, make sure you hit the "Choose File" button when uploading your file to the sanitizer, lol.

Interesting!  I wonder what the issue is.  If you can PM me the 73x25 one, I'll try to figure out what's going on.

Based on my simple testing so far with their pre-gen'd maps, I've confirmed Arkenforge's .uvtt format also works in the scrubber! But more testing is recommended. Gonna test to see if I can do something similar with animated maps too but that's doubtful. Upon further testing, got it working with animated too (by following regular process then Arkenforge's animated steps then making "image" invisible as you can't use GM Notes on animated maps). But I did notice it imports the lighting info wrong and gave me -4475 ft radius on the lights. Small price to pay for everything else setup.

Hmm. That's not right. Can you PM me the JSON you used so I can track down the issue?

If this isn't the right place for me to post this, I apologize. But I figure that I'm not the only person using Dungeondraft, and one of the recent updates added the ability to place objects that block line of sight for dynamic lighting. Opaque objects in Dungeondraft don't work with the import sanitizer out of the box, which was disappointing. But I monkeyed with the output until I got it to work, and I'm posting it here because I don't know of anyplace that would be obviously better. When a .DD2VTT file generated by Dungeondraft is added to the sanitizer, it will include some JSON markup like this: {"format":0.3,"resolution":{"map_origin":{"x":0,"y":0},"map_size":{"x":40,"y":40},"pixels_per_grid":70},"line_of_sight":[[{"x":29.822109,"y":2.938543},{"x":29.243984,"y":3.2875}],[{"x":29.285625,"y":2.865625},{"x":29.884609,"y":3.308332}]], "objects_line_of_sight":[[{"x":11.625455,"y":10.461274},{"x":11.635423,"y":10.168058},{"x":11.636104,"y":10.160276},{"x":11.565085,"y":10.07564},{"x":11.479475,"y":10.06815},{"x":11.417505,"y":10.148993},{"x":11.417165,"y":10.152884},{"x":11.351352,"y":10.143206},{"x":11.347461,"y":10.142865},{"x":11.280827,"y":10.725211},{"x":11.280487,"y":10.729103},{"x":10.481196,"y":10.721912},{"x":10.480856,"y":10.725803},{"x":10.396121,"y":10.663494},{"x":10.372772,"y":10.661451},{"x":10.334346,"y":10.697301},{"x":10.334005,"y":10.701192},{"x":9.922686,"y":10.696576},{"x":9.922345,"y":10.700467},{"x":9.626113,"y":10.635339},{"x":9.594982,"y":10.632615},{"x":9.612396,"y":10.657665},{"x":9.611375,"y":10.669339},{"x":9.42814,"y":10.657229},{"x":9.4009,"y":10.654846},{"x":9.342335,"y":10.696776},{"x":9.338444,"y":10.696436},{"x":9.321956,"y":10.840077},{"x":9.318551,"y":10.878991},{"x":9.3867,"y":10.951613},{"x":9.386359,"y":10.955504},{"x":10.876807,"y":10.995715},{"x":10.877148,"y":10.991824},{"x":10.892519,"y":11.040223},{"x":10.892179,"y":11.044114},{"x":11.188265,"y":11.066097},{"x":11.258309,"y":11.072226},{"x":11.272078,"y":11.27341},{"x":11.26663,"y":11.335672},{"x":11.166483,"y":11.942533},{"x":11.165802,"y":11.950316},{"x":11.192993,"y":12.042883},{"x":11.192653,"y":12.046774},{"x":11.346947,"y":12.075958},{"x":11.346606,"y":12.079849},{"x":11.43139,"y":12.051976},{"x":11.439173,"y":12.052657},{"x":11.464076,"y":11.992097},{"x":11.467968,"y":11.992437},{"x":11.545346,"y":10.928727},{"x":11.546027,"y":10.920945},{"x":11.629346,"y":10.461615}]] The portion beginning "line_of_sight":[[ is where Dungeondraft puts the JSON for stuff drawn using the wall tool, and that stuff works fine. But later on, there is another piece of markup ]], "objects_line_of_sight":[[ Which is where the XY coordinates from the "line of sight" section end (that's the "]]" part), and a new section begins. That section  is where Dungeondraft puts the stuff generated for objects that are meant to be opaque to lighting/line of sight. The script does not recognize any of the stuff in that section. But you can easily fix that; just edit the portion that reads ]], "objects_line_of_sight":[[ so that it instead reads ], [ before you run !uvtt, and the importer will draw them in the Dynamic Lighting layer. This way, all the stuff that would have been in "objects_line_of_sight" is instead in "line_of_sight", which UVTT Importer will interpret properly.
