recastnavigation + irrlicht

[easy163]

Hi, I downloaded recastnavigation and can't compile the demo example of which is found on the forum http://irrlicht.sourceforge.net/forum/v ... =9&t=47017.
Demo example of the recastnavigation compiled without problems.
In the debugger writes

The way that I plugged


What could be the problem? Please help

Spread the project in Visual Studio 2012 http://puu.sh/4m5BL.zip

[smso]

Check the following:

1. Make sure that the relevant .cpp files are compiled to the corresponding object files, e.g. RecastMesh.cpp to RecastMesh.o
2. Could the compiler find the object files?
3. Have you linked the object files?

Here is the last version of the project and libraries (3 pieces)
http://yadi.sk/d/4q8cCusF8tthN
http://yadi.sk/d/A0GjLLEt8uBNs
I compiled static library and now writes only 2 errors
Can see what did I do wrong?

It's helpful if you could post the 2 errors in compilation.

the libraries not found the correct function is likely, although everything seems to compile correctly

I guess the linker cannot find the recast_util.obj file. Please check your version of Visual Studio on how to include the .obj file or its location in the linker's properties.

Or, as a workaround, you can try appending the absolute path of the object file to the LIB environment variable.

The linker has recast_util.obj. It cannot find the references in that file, namely BuildContext and AC BuildContext (??!!).

Compiled neatly, 5 libraries recastnavigation. An example could gather, when you start the Console writes that generated the navmesh, but after the app crashes. Perhaps the example of the curve, try to write itself. Thanks for the help

[mongoose7]

Compile it for debug then run it in the debugger to find where the crash occurs.

Find other libraries, the library found AI http://inexin.sourceforge.net/. There is a function of the host Triangles

Code: Select all

 
ai_index AI_NavigationMesh::addEdge  ( ai_index  i_t1,  
  ai_index  i_t2,  
  ai_index  i_v1,  
  ai_index  i_v2   
 )    
 
Add edge into navigation mesh. 
Parameters:
 i_t1  Index of the first adjacent triangle of winged edge.  
 i_t2  Index of the second adjacent triangle of winged edge.  
 i_v1  Index of the first vertex of the edge.  
 i_v2  Index of the second vertex of the edge.  
 

I can not understand that the first and second her post, now at the top of the mesh 4, 2 triangles, 5 faces.
I touch all the vertices and add their coordinates

Code: Select all

navigation_mesh.addVertex(*listVertexPositionIterator);

Then I realized that would convey the triangles should be sent to the top three. So far I've manually added them to avoid mistakes, those indexes that I received when iterating vertices.

Code: Select all

 
navigation_mesh.addTriangle(0,1,2);
navigation_mesh.addTriangle(1,0,3);
 

Next you need to add 5 edge, I can not understand what I'm doing wrong. Add 3 edge of the first triangle

Code: Select all

 
navigation_mesh.addEdge(0,1,0,1);
navigation_mesh.addEdge(0,1,1,2);
navigation_mesh.addEdge(0,1,2,0);
 

Next, 3 or 2 CSE need? Even if you add only one like this

Code: Select all

navigation_mesh.addEdge(1,0,1,3);

When you start writing that the triangles are too many edges.
What am I doing wrong?
