Best way to convert/port other platform games developed in other languages like C++ etc in iphone?

In order to port games in to iphone, I dont thing complete Objective C coding is required. A开发者_如何学Gos I have seen most popular games which were on other devices or on other platform. Now converting exactly to iphone.

Is it there any tool for it ?

There are a few different tools out there that allow you to develop once and deploy to multiple platforms. Some of these are full engines, like UDK, Torque, and the aforementioned Unity. There are also tools like PhoneGap and Adobe Air, which allow you to develop using web technologies, and then convert to mobile apps.

Of course, sometimes you have to just write your code using C++ and OpenGL, and port it to each platform individually. This will allow for a bit more control and performance in some cases, and might allow for better access to the API of each device, but the trade off is that it'll take a bit of time to port.

I think this is easiest accomplished by creating a platform independant C/C++ library which can than be linked to from Objective C or loaded with JNI on Android systems.

But I don't think that there is a translator for languages, since the APIs are very different.

Another option is to create the game with a language independent game engine like Unity (which is commercial btw).
