I've been using Tiled to create .tmx maps for one of my projects, maps that I export to JSON before using with Phaser.js.
Problem is, a few months ago I mistakenly deleted the .tmx file for the game first map. It's still working fine but now I can't change anything on the first map layout with Tiled because I only have the JSON for it.
I've been looking for an answer with no success so far, but is there a way to convert a .json Tiled map exported from a .tmx file, back to its original format ?
You should be able to simply open the JSON exported map in Tiled, and save it again as a TMX file. To be able to select the file, you may need to change the file type in the Open File dialog.
Btw, you should consider committing your project to a version control system (Git is a popular one), so that such mistakes will not generally lead to loss of data. You don't always get lucky.

I created a blender project, exported it as JSON+BIN files and showed it through the blend4web webplayer. Everything goes fine until my need to change the JSON file programmatically to add/remove a new 3D object (e.g. a cube or rectangle). I want to renderize the already showed 3D model adding or removing a 3D object. However, since the exportation of a project to blend4web generate a .bin file, if I change only the .json the model was not showed as expected. Considering this scenario, the unique way to change the model is modifing the .blend file and exports it again from Blender. But based on my need, I can't add a new 3D object in a Blender project programmatically considering the .json file. Additionally, the .json file which I am updating/using is considering data retrieved from a Database, such data indicates how and the position where the new 3D object will be displayed in the scene, which hinder me to use Blender to create a 3D Model modificated.
In this perspective, I need help to identify:
Which is the best way to change the scene and show it in blend4web programmatically and mainly considering a .json as an input for the model?
Is there any python script to user a blend4web .json file as an input to be compiled, without the Blender project and regenerate the .bin file, making it possible to show correctly my 3D model using the blend4web webplayer for JSON files?
Or, is there some (easy) way to modify a project from Blender considering data in JSON format, compile and generate the files to be shown programmatically by the blend4web webplayer (for JSON)?
Thanks in advance.
I've implemented offline viewing based on the tutorial and github here. The problem I'm having is forge is looking for the db jsons in an odd location that makes url pathing awkward. The files in particular are 'objects_attrs.json.gz', 'objects_vals.json.gz', 'objects_offs.json.gz', 'objects_ids.json.gz', 'objects_avs.json.gz'. For some reason the forge viewer strips two layers of directories off the url then looks for the files there. Afterword Forge looks for the files in the original location but, looks for the straight json instead of the gziped jsons.
This can be handled in a few hacky ways like creating two arbitrary parent directories in the url and accepting files at the higher url as well. Or unzipping the gzips and saving them in location. But, these kind of hacks could easily be unstable if I'm not exactly right about the forge implementation.
Is there any reason these files are searched for in a different location? For example are these files also used by the 2d files not just the 3d files? Are there other files like this?
Look for the .svf file, say it's Design.svf. Rename it to Design.zip, and then upzip the file. This will get you the manifest.json.
Inside the manifest.json file, you'll file the URI's of all the files, including the one's you mentioned (the property database files).
Modify the URI as you wish, save the manifest.json file and re-zip it back up and rename it back to Design.svf.
If you got the URI path matching your file-system, then those property files will now load correctly.
Good luck!
I would like to use the parallel coordinate toolkit from syntagmatic.github.io/parallel-coordinates/#.
As I am new to the D3.js framework, I am encountering some trouble to begin and visualize data locally.
What I am trying to achieve is to use one of the standalone HTML examples (e.g. brushing.html) and edit the data table with my own data.
I stored locally (in a Windows folder):
the brushing.html example file
the cars.csv file
the D3.js library files from d3js.org (d3.min.js and d3.js)
When I load the HTML file in my browser, only the text displays, not the parallel coordinates themselves.
What am I missing/doing wrong? Should I be able to display locally the same result as what appears in brushing.html?
I checked out several tutorials for D3.js, but they generaly skip these preliminary requirements step. Thanks for any feedback.
Thanks to the straightforward comment to my question, I was able to identify the issues checking the browser's console.
It mainly came down to redefining paths to the different files, and eventually downloading the missing packages from the corresponding Github page https://github.com/syntagmatic/parallel-coordinates
I can now test the tool locally with custom data.
I am trying to build a custom map in Tile Mill and am new to programming in general so I apologize is if comes off as uninformed. I've done research but I'm not sure if I'm looking in the right place.
My basic question: this is an embedded map of restaurants in the SF area. Is there a way for me to extract the data for the locations to use in building a custom map of my own?
http://www.sfgate.com/food/top100/2012/map/
It seems that if the location markers exist on a map, that meta data is somewhere, I just don't know how/where to access it....I believe the raw formats for inputting location into a map are CSV or KML and wondering if there is a way to extra these data types from embedded maps.
Thanks!!
View the source of the page in question, look for the data (it's under the variable mapLocs, copy it from the page, and write a little script to convert their format to CSV.

Is it possible, via Adobe Air, to save multiple types of data in a single file? For example, an application would allow the user to load in external images, position them on stage and label them. This data would be then be stored in a ByteArray (I guess) using BitmapData for the images and probably XML for the metadata.
I would then like to write this to a single file, with a bespoke file extension that could be associated with said Air app.
I've asked this on various forums and never received a single reply.
You can add everything to a byte array and write it to file - but defining boundaries and extracting individual entities back from the file would take some effort. How about writing them to normal files, zipping them to a single file and deleting the originals? This way you can still have a single file and deal with the individual items more easily.
This article describes some ActionScript zip libraries. I've used nochump in the past and it was easy - this page has some sample code
If you want some individuality for your files, you can rename the zipped file to whatever extension you want - that's what Firefox extensions do, they have .xpi extension, but they're plain zip files renamed.
