XL Engine source code release!

[Dyskos]

Personally, Blood is my favorite Build Engine shooter, but BloodGDX works pretty well already. I love Star Wars, and I like playing Dark Forces, but I honestly don't need a source port for that.

I like Daggerfall Unity and what Interkarma has achieved thus far, but I don't like that it depends on... Unity (a proprietary engine, no less). It's also comparably slow, when a source port of a game from that era should run ludicrously fast on modern computers.

If I comment out that line, it compiles and then we get:

It Lives!

I see shadows are working!

OMG, can't wait to get home Great job.

Still need to fix the issue on
https://github.com/Mindwerks/XLEngine/b ... g.cpp#L577

something doesn't like being overloaded. :/

Now I need to figure out how the individual 'plugins' worked and where loaded into xlengine.

Right now, nothing in the DaggerXL, etcXL compiles. I'll need help there as well if anyone would like to try.

Well... This XLEngine source drop is not a 'source port' of the games in question but an re-implementation. LuciusDXL was working on a source port, by reverse engineering the binaries through the DosBox debugger.

However, your point stands. I'm not sure where XL Engine will take us. As saidin the opening post, BloodXL and OutlawsXL are mostly the beginning bits and nothing of substance.

Looks like it's having trouble seeing the global operator== to test if two strings are equal. afritz1 made a pull request to work around the issue (and I made one to add a basic CMakeLists.txt, to make it easier to build).

I have it building now, but unfortunately it's not working for me. It seems to require a specific version of AngelScript that's older than the current. It includes angelscript.h for the version it wants, but the user has to install the specific library version or else the linked executable will crash (I tried updating the built-in header, but got a bunch of compile errors due to missing methods).

I saw that you were working on it, I checked the forks. Thanks!

I ran into the same problem you did, using the latest AS is a no-go. You can use the release zip (AprilFirst.zip), in there is the version that LuciusDXL used. There are two copies of the sdk in there (checked into svn?), anyway... it works for me.

To be clear, the linux XLEngine hard linked against DarkXL, so my next step is to create a DarkXL.so file.

Basically all *XL plugins are nothing more than libs, so files in Linux.

Almost there...

Starting DarkXL version 9.500
Start UI Script: DarkXL/CoreUI.as
Error: Failed to load DARK.GOB

[psi29a]

So XLEngine is currently hard coded to look up DarkXL.so, so we put that beside the XLEngine binary. It complains that is needs the AS files, ok, we create a DarkXL directory and copy all the DarkXL *.as files to it.

Code: Select all

bcurtis@Wintermute:~/Workspace/Private/XLEngine/xlengine/linux/DarkXL$ ls
ccd.id    DARK.GOB      DarkXL     dirinfo     drive.cd   imuse.ini  lfd        sounds.gob   stealth       XLEngine
dark.exe  darkpilo.cfg  DarkXL.so  dos4gw.exe  imuse.exe  jedi.cfg   local.msg  sprites.gob  textures.gob

Remember, it is looking for DARK.GOB, on ext4, everything is case-sensative so I had to rename dark.gob.

We load it up, and now we have script errors... so close, yet so far...

Fixed this AS problem... apparently missing string (missing param) in Create Window in the AS files of DarkXL.

Now we just get this:

At this point, it's trying GOB_Reader::Open(char const*)... and we get lost along the way. Any ideas?
