Tools:
This project is going to be built with Unity since I have a lot of experience working with it. It will make long-term maintenance a pain (annual upgrades), but it shouldn't take more than a few hours each year to update. It will be very important not to let the project rot to the point of being unsalvagable.

The editor's missions will work exclusively with the C# Mission SDK through the use of its JSON data files. There will be an extra feature to export the MAP portion through OP2 Utility, but for the most part, data will be saved in JSON. For devs that prefer to work in C++, don't forget you can link to the C# SDK and continue working in C++.

Slightly related, I had a project I was working on a while back that converted the Outpost 2 map file to JSON format. Not sure it would be useful to you though. It mostly just made use of OP2Utility, which you can use directly.

Would be good to have extra map data stored in JSON format, rather than forcing people to write executable DLL code.

techcor,

This sounds ambitious. Good Luck! I would be willing to do some light testing for you if it gets far enough along.

We should talk about your use cases for the sprites contained in Outpost 2. Currently, OP2Utility will just extract individual frames. You will probably want to show composite frames of structures. I wanted to program this, but wasn't good enough at the bitmap format at the time. I could take another look at it though if you think it would be helpful.

At any rate, please report any bugs are wanted features in OP2Utility. I'll see what I can do to accommodate the changes.

----

Hooman, if your ideas are fairly well fleshed out, maybe it would be good to get it in the repo so techcor can use it?

I'll have to dig up the project and upload it to GitHub.



Actually, I was just thinking, a C# project that could run with Mono would work on Linux. That would be wonderful. The current OP2 editor doesn't run on Linux, and trying to update it so it does sounds like a rather difficult undertaking.

Just committed OP2Utility.NET's source to GitHub.

Unity can build to Linux, so the editor will work there as long as an ".so" can be built from the OP2UtilityForC project in OP2Utility.NET. Someone will need to check that source out and see if they can make an .so. No rush though, OP2UtilityForC has not been tested yet.

----

The editor has the menu options set up. Going to add the code behind them later tonight now that I have OP2 Utility for C#.

For those who are curious, the link to the project is:
https://github.com/TechCor8/OP2UtilityDotNet

Edit: Ahh, I see now. You edited your first post and added a link.



Interesting how it converts the C++ API interface to a C compatible one, and then wraps C# classes around the C interface.


I gave the project a try from Linux. I needed to first get some Nuget packages with dotnet restore. The Microsoft build tools don't really know how to build C++ projects from Linux, but I was able to specifically build the C# project with either msbuild OP2UtilityDotNet or dotnet build OP2UtilityDotNet.

Yes, the C compatible interface is what needs to compile on Linux. I suppose it needs a CMake file or something. I'm not familiar with it.

Since C# compiles to IL code, the DLL from Windows will work on Linux. The JIT compiler on the user machine should take care of it.

Although, I will need a special DLL anyway to change DllImport to point to the Linux C library. That is something I can prepare easily.

Looks like I am able to load and save maps and missions (File Menu). Going to look at rendering tiles to the tile map.

EDIT: I fixed it! Turns out the map was upside down and the tile graphic indexes needed to be inverted.




Update:

Submitted editor source. It's currently just a "Map Viewer" where you can import and scroll around maps, adjust grid overlay color and alpha, and export the map. Not going to bother with a release build yet.

I tried checking out the project. There didn't seem to be a project file. I saw some DLL files, but no EXE. Not really sure how to run it.



Meanwhile, the JsonMap project that was mentioned earlier has been uploaded to GitHub. Probably not directly useful for your editor though.

The folder itself is the project file. You need Unity to open it.

Update:
  • Added minimap with navigation
  • Added Mission Properties
  • Added Player Properties
  • Added Windows build for interested parties to take a gander.

Next major task is the paint pane.


Now that I have a better understanding of how maps work, it's clear that the mission API can't fully control the graphic in the tilemap. I thought the entire game was using one big atlas.

I'm thinking the two alternatives now are exporting the map and opm files separately (which is how these are currently read), and/or bundling them into a special mission vol file with a different extension that gets read by the C# Mission SDK. Maybe both.

So options in the File menu could be:

Open (omv / Mission Volume)
Import Map
Import Mission (opm)

Save (omv / Mission Volume)
Export Map
Export Mission (opm)
Export Plugin (Native C DLL hook)

Of course this would require modifying OP2 to look for maps from a different vol extension. Probably not worth it.

Suggestion, it would probably be better to use the GitHub Releases feature instead of providing the release directly in the repository. Just FYI. :D

Done.


Quick brief about how to use the current version:
  • When you open the editor, you will be asked to select your Outpost 2 game folder where it can find the system vol files. If you set this to the wrong directory, go to File > Preferences.
  • By default, you are staring at a "New" map. You can't really do anything yet with a new map, so go to File > Import Map...
  • Set filter to .vol unless you have loose .map files lying around. Select maps.vol to get a list of maps.
  • Voila! Map Viewer 3000! Use arrow keys to move, shift to move faster, or use the minimap under the View menu.
  • Export Map and Open/Save mission should work, although I haven't tested in a while.
  • Mission and Player properties configure the mission json file. The output already works with the C# Mission SDK (In fact, it uses it to make the json file.)

That's it for now!

It's definitely a great working prototype! I gave it a shot last night and was generally impressed.

I dislike the UI as it's not native but that's truly a minor gripe.

Only thing I noticed is that when importing a map, it kinda hangs for a bit. Or at least, it appears to. If I had to guess I'd say it's doing a lot under the hood to convert to an internal format that the editor can work with. Might be good to add a loading text or change the cursor to a wait cursor, something like that. It's a comment about usability and UI's that are 'responsive' to the user. Granted this is early work so I wouldn't go too far into worrying about issues like that before functionality is in place. :D

Anyway, good work! I'm excited to see where this goes.

Yes, I would prefer native UI also, but that's the price to pay to use Unity.

I already profiled the import map. Most of the load is coming from color averaging the tiles for the minimap (about 75%). Maybe there is a faster algorithm. I've thought about skipping pixels, but that might affect image accuracy.

Actually, a loading bar is not a bad idea. I can have the percentage be the number of tiles loaded / total tiles. It would would look pretty smooth.

A faster way to do it would be to average the colors of the tilemap itself, build an index table then build the minimap using the index table. E.g., tile index = color index = pixel or however you're generating the map. It's very fast in the prototype code that I built a couple years ago.

Could even pre-cache the index table, e.g., on first run as part of the set up go through all of the tilesets, determine an average color value and store in an index. Can save it out however you think is appropriate and then just load that if the file is present.

That's pretty much how the MapImager works. It loads the tilesets, then precomputes scaled tiles for the given scale factor. When it renders the maps, it uses the scaled tileset rather than the original one.

Likewise my python map code precomputes the scaled tiles for the desired scale. I put the code here https://forum.outpost2.net/index.php/topic,6275.0.html, it is pretty short and fast thanks to numpy magic.
