Hi ixnehc- There are a couple things: 1. You need to specify an errorReport function. You can't simply pass in NULL. The simplest thing is to define a function that forwards to printf (as shown in the SimpleConsoleMain standalone demo):

static void HK_CALL errorReport(const char* msg, void*)

{

printf("%s", msg);

}

Once you have that defined, your hkBaseSystem::init line looks like:

hkBaseSystem::init( memoryRouter, errorReport);

2. Your hkpWorld is "scoped" to the if(result==HK_SUCCESS) {...} block. In order to use that variable outside of the if-block, you must do this:

hkpWorld* world;

if (result==HK_SUCCESS) {

...

world = new hkpWorld(info);

}

Otherwise, the world variable will go "out of scope" when you exit the if-block and subsequent code will not be able to use it! This sort of thing is checked at compile time. 3. Take a look at the code in: Demo\StandAloneDemos\ConsoleExample\SimpleConsoleMain.cpp to see the absolute minimum required to configure Havok. If you do all that and still have problems, I can help you better if you tell me exactly which demo you copied your code from. Also, more information on what is reported when a crash occurs would be useful. -Josh
