Hello, i wonder if its possible to use the D2XX USB driver from www.ftdichip.com in 3D Gamestudio to get USB support? Its only a dll file and a .h file that contains functions for USB connectivity. Is it possible to use any dll file in 3D Gamestudio?

depends, you might need to write a wrapper for it, but ultimately no matter what you can get it to work, you just might need to know w little c++ to do it.

What is a wrapper? And how do you write one in c++?

well, if a program needs a specific setup in a dll, then you can write a seperate dll to be a "middle man" which speaks with both the engine and the desired library. Its the type of thing that people have been doing with enet and fmod.

OK, that question is answered...still doesnt tell me exactly how they are written, but I guess I will find that out as I study c++. Now for another question : why would anyone need USB connectivity for gstudio? I thought usb was a protocol for peripheral devices on a computer,...I am having a hard time seeing the link between gstudio...I mean, my mouse is usb and is working fine in the engine.

First, this dll works fine with for example Borland C++ Builder without any wrapper, does that make it more likely to work with 3dGS?

Second, im a hardware engeineer, and i would like to build some cool input unit to 3dGS, like a VR glove or something.

this sounds interesting. Running this dll inside 3dgs should be possible. If it is c dll it most likely to run directly, but if it is not you'll need a wrapper. Doesn't sound hard....

Why is that? Is it because gstudio is programmed in c therefore it is the native language?

Sounds promesing, i will post the .h file and the dll below if anyone want to look at it and tell me if its possible. I have some strange include problem right no so i cant test it myself.

ftd2xx.h
ftd2xx.dll

this will need a wrapper i guess, looks like someone with experience in plugins can easily write a wrapper.
