<p>So now that we have some window, we can create an Irrlicht device

inside of it. We use Irrlicht createEx() function for this. We only
|

|
need the handle (HWND) to that window, set it as windowsID parameter
|
||
|
|
and start up the engine as usual. That's it.</p>

<p>Now the only thing missing is the drawing loop using IrrlichtDevice::run().
|
||
|
|
We do this as usual. But instead of this, there is another possibility:
|
||
|
|
You can also simply use your own message loop using GetMessage, DispatchMessage
|
||
|
|
and whatever. Calling<br />
|
||
|
|
Device->run() will cause Irrlicht to dispatch messages internally
|
||
|
|
too. You need not call Device->run() if you want to do your own
|
||
|
|
message dispatching loop, but Irrlicht will not be able to fetch user
|
||
|
|
input then and you have to do it on your own using the window messages,
|
||
|
|
DirectInput, or whatever.</p>
