OIS Integration Tutorial

pc0de · Post by **pc0de** » Mon Aug 18, 2008 10:22 pm

OIS (Object oriented Input System) is an alternative 3rd party input processing library.

The initial draft of Integrating OIS with Irrlicht is now available on the Irrlicht Engine Wiki.

Thanks go to hybrid for implementing the necessary Irrlicht changes which allow OIS and Irrlicht to work properly on Linux.

No problem, it was a good/fun experience for me on several fronts.

You shouldn't need to do anything on visual studio except:

- use the files on the wiki page ( COIS.h, COIS.cpp, main.cpp )
- link to irrlicht.lib and OIS_static.lib (which you have already compiled separately )

..also, if you are using vs express i don't know you might have a problem including windows.h? in that case find the windows platform sdk to install

I use codeblock with gcc. In COIS.h is #include "OIS.h" so i must include ../ois/includes or else it cant find it. But then i get errors like D:\ois\src\win32\Win32InputManager.cpp|78|undefined reference to `IID_IDirectInput8A'|
D:\ois\src\win32\Win32InputManager.cpp|78|undefined reference to `DirectInput8Create@20'|

Including dx sdk cant fix it..

OK, finally i compiled, but now then i move any joystick axis program crashes... with other joystick program crashes instantly on load. Is this OIS bug or wrapper?
Edit: program crashes in bool COIS::axisMoved then calling arg.state.mAxes[axis].abs

the printf statement is crashing because it's trying to print an int with a string (%s)...

Thanks for the heads up fellas. I've made the necessary corrections to COIS.cpp.

Thanks, it was so easy, but i searched deeper. Started looking mistake in OIS files

On the wiki it says

OIS provides both a Visual Studio solution file and a CodeBlocks (mingw) project for building static libraries on Windows. To build using Visual Studio, open the solution file located in the directory "Win32" off of the OIS installation directory {OIS Install}.

But it only says for visual studio...how about code::blocks?

and when i try to run DemoFFTest.cbp in codeblocks and build it i get a error saying :"ld.exe||cannot find -lOIS_static_d|"
does anyone kow why i am gettign this error?, thanks in advance.

MasterM - I see that pjcast responded to your question in the OIS forum.

Note that when I try to build the OIS static libraries using CB, the compiler throws: "dinput.h No such file or directory". So you'll need to modify the project file to point to the proper location.

I'll have a look at adding an example of Win32 Force Feedback to COIS.

I use code::blocks with ois. In newest ois missing one file, you need to include ois/src/OISException.cpp to project (project->add file) and you need DX SDK.
In project build options select OIS and include in search directories:
C:\Program Files (x86)\Microsoft DirectX SDK (August 2008)\Include
..\includes\win32
..\includes\
then select OIS_DebugDll and in linker settings add dinput8.lib and dxguid.lib from DX SDK. Do same with OIS_ReleaseDll.

P.S. Now just need to add 2 or more joystick support (then printing joystick events):)

Added a section in the wiki on Force Feedback. Also updated the sample code:

-Dump OIS events to GUI listboxes.
-Creates and plays a Constant Effect initiated by the "F" Key or Joystick button 7.
-Control the effect Magnitude with a GUI scrollbar.
