How do i get my game to work with the euphoria engine? if you dont know what that is heres a link. http://www.naturalmotion.com/euphoria.htm
Euphoria isn't really middleware. From their site:
euphoria is not middleware. Instead, NaturalMotion has close co-development relationships with publishers and development teams to integrate euphoria into their next-generation titles. This allows clients to hit the ground running and produce euphoria-enabled games within short time frames.
Basically it's more like a consulting service that has some tech and art associated with it..
You don't. Unity itself is a game engine, and combining game engines into one another is not only an incredibly complex, advanced, and involved process, sometimes it isn't even technically possible. You would probably need a team of software engineers that were intimately familiar with C++, Unity, and Euphoria to pull this off, and that's assuming the two are compatible with one another.
Not to mention the Euphoria engine isn't freely available, it needs to be purchased by an authorized reseller, and it probably costs quite a bit of money.
udk is also a game engine but it uses euphoria to create unique animations in realtime which u can't get in unity......i was also searching for that too btw...
