I want to use OpenSteer for my game that I want to be compatible with the Xbox 360. I have heard that since it is a wrapper for a C++ library, it will work in XNA on a PC, but not on the Xbox. Is there no way to make it compatible?
UPDATE: The C++ version may not be, but what about OpenSteerDotNet?
No, not if you're not a professional game developer, got an agreement with Microsoft and pay them for their SDK (hardware include).
XNA don't allow native code on the XBox360.
You're only alternative is to use a .Net implementation of the same library, OpenSteerDotNet as suggested in comments.
According to the OpenSteerDotNet homepage:
It should work fine with XNA Game Studio Express, including the XBox 360 runtime.
