p3recastnavigation

Description
p3recastnavigation is a project that exposes most of the commonly used features and functionalities of the Recastnavigation library (github.com/recastnavigation/recastnavigation) to the Panda3d engine as an extension module.

The code is available at (master branch):

https://github.com/consultit/p3recastnavigation.git

To build and install it, see INSTALL in the source code.
To start with it, see NOTES in doc folder
To start use it, see the basic, test1 and test2 examples (both python and c++) in the samples folder
Here is a short video test2

Features
p3recastnavigation derives its functionality from the comprehensive “RecastDemo” application, you find in the original site, which I highly recommend you to use to find out all the features of the libraries; also it adds some extensions and flexibility that can be useful in other applications such as:

managing multiple nav meshes
ability to set parameters as strings to facilitate the use of external configuration files, such as XML (data-driven)
possibility to define more area types and costs
possibility of throwing events (currently only move or steady events)
integrated possibility of using “kinematic” agents which fix the position on the surface of the geometry on which is built the navmesh
custom update callbacks
implementation of the TypedWritable api to write/read nav meshes and crowd agents in/from bam files

Limitations

p3recastnavigation exposes only some features of “recast” and “detour” (the most useful) and is not a porting of the core functionality of the libraries
the code doesn’t use multithreading
the code, at present, is not optimized
development and tests has been made only on Linux, so it is greatly appreciated testing on other platforms (there is not platform specific code inside the project). Currently, it is built as an extension module using the tool, slightly modified, P3DModuleBuilder (github.com/tobspr/P3DModuleBuilder.git) by tobspr
development and tests have been made using recent versions of panda3d (built from git source tree using makepanda)
bugs and errors: don’t hesitate to signal when you find one

I hope this module could help Panda3d programmers to integrate path finding functionalities offered by Recastnavigation, in their own code.

[!] FATAL ERROR: Subprocess returned no-zero statuscode!

as I said P3DModuleBuilder is used to build, with a minor change (i.e. to prevent “interrogate” and the compiler to visit the subdirectories of the folder “source”). But the error does not seem due to this, rather to the compiler flags: try to compile with a different level of optimization in config.ini:

optimize=2/3/4

and re-execute

pyhton build --clean

If the error persists, it will be necessary to ask the author of the build tool (tobspr) if the changes I made to are responsible or if it is another type of error.

wezu · May 8, 2016, 5:06pm

No luck so far
“optimize=2” gave me some other output … but it’s to long to post here, so here’s a link to a gist:

yes too much errors and warnings, but please note that p3recastnavigation has been developed using recent version of panda3d (built from git source) with c++11 support and uses several c++11 features. So you could check your compiler compatibility.
Unfortunately I don’t know the windows build environments, and at this point, any help from a expert would be appreciated.

wezu · May 8, 2016, 8:11pm

I am using a version of p3d build from git today, but all I know about building it is how to type ‘makepanda\makepanda.bat --everything --installer --no-eigen’.

consultit · May 9, 2016, 10:03am

After some research on google I found out that some warnings/errors are due to the peculiar interpretation of the standard by msvc. In any case I committed some changes, and you can try to build now.
Let me know

wezu · May 9, 2016, 3:17pm

This time I only got 11 Warnings and 142 Errors
log: gist.github.com/wezu/806f55ad4f … 8c7267587f

It’d be nice if someone else would also try to build it on windows, my systems are known to be cursed and just because it fails on my end it doesn’t mean it’s broken. There are numerous things that refuse to work on my PC for no apparent reason. It’s uncanny but not unexpected.

consultit · May 9, 2016, 7:37pm

I made some more modifications and removed c++11 features.
Now it should build with much less errors (I hope).

wezu · May 10, 2016, 3:30pm

I’m down to 13 Warnings and 3 Errors, log: gist.github.com/wezu/a1c52fb268 … 5272248b4c

consultit · May 10, 2016, 6:53pm

Committed changes to prevent errors. The warnings are due precisely to recastnavigation library so unavoidable.
Now it should compile with even fewer errors.

Ok there are two pieces of news: the good news is that the code compiles correctly now (aside warnings of the library and of the compiler itself complaining for several unknown options), and that makes me happy; the bad news is that the link with python libraries:

LINK : fatal error LNK1104: cannot open file 'python27_d.lib' [C:\p3recastnavigation-git\win_amd64_py27\p3recastnavigation.vcxproj]

does not work.
python27_d.lib should be the python debug version, and probably you do not have it installed, but only the release version (without _d). The problem is that the choice of the type of library (debug / release) is made by cmake that is used by P3DModuleBuilder tool.
I think that now you can try “optimize” 3 or 4 (without debugging) and see if it is selected python27.lib, and for case 1 or 2 (with debugging) you should find out how to install python27_d.lib.

Optimize 3 gives some new error

Optimize 4 complains abut something else:

The first error is related to p3recastnavigation and I committed a change to correct it.
Unfortunately the second one is due to a symbol that is not found in a Panda3D library in windows , so it should be investigated further (in this case I’d be of little help).
In any case if you want to enable debug drawing also with optimize 3/4 you can change the CMakeLists.txt file by replacing the section

  elseif(OPTIMIZE STREQUAL "3")
    add_definitions("/MD /Zi /GS- /O2 /Ob2 /Oi /Ot /fp:fast")
  elseif(OPTIMIZE STREQUAL "4")
    add_definitions("/MD /Zi /GS- /Ox /Ob2 /Oi /Ot /fp:fast /DFORCE_INLINING /DNDEBUG /GL /LTCG")
    add_definitions("/Oy /Zp16")

with this

  elseif(OPTIMIZE STREQUAL "3")
    add_definitions("/MD /Zi /GS- /O2 /Ob2 /Oi /Ot /fp:fast /DRN_DEBUG")
  elseif(OPTIMIZE STREQUAL "4")
    add_definitions("/MD /Zi /GS- /Ox /Ob2 /Oi /Ot /fp:fast /DFORCE_INLINING /DNDEBUG /GL /LTCG /DRN_DEBUG")
    add_definitions("/Oy /Zp16")

I’m sorry if I’m a pain in the arse.

I got it to compile (well You got it to compile, I just did what you wrote), but I can’t get the sample to work, it crashes python.

This is strange: it seems related to audio library (for example see stackoverflow.com/questions/1616 … losed-mean).
But sample code does not use absolutely audio (obviously).
Look at panda3d.org/manual/index.ph … _Variables to see if you can disable audio; may
be “audio-active 0”.
Let me know.

P.S.:Your cooperation has been invaluable to make this application more portable

wezu · May 12, 2016, 11:49am

I don’t think it’s audio related, it crashes python (“python has stopped working”), I have to kill the window and Open AL complains about that. I put in loadPrcFileData("", “audio-library-name null”) and the open al error is gone… but the program hangs just as it did.

consultit · May 12, 2016, 3:00pm

Ok, could you use a debugger and going step by step, inside the various functions too. And report me where it exit?
From the output the nav mesh should be correctly set-up: this is good.
Now I’m busy, but later I can write a simpler example so you can test essential steps to see if the api is ok, even without a debugger

consultit · May 12, 2016, 6:01pm

I committed a small program “test.py” in samples to test the essential functions of the module.
Also every time you change config.ini P3DModuleBuilder requires to execute

python build --clean

(in doubt you should always run it)
Now try running the test.
