Hi all!

I'm a beginner in writing C++ plugins for C4D. I would like to control the rotations of the camera in the active viewport. I've read the basics about writing plugins in C++ and I think my plugin class should derive from SceneHookData.

The problem seems to be the registration of my plugin. Here is my code :

Main.cpp

#include "c4d.h"
  
Bool RegisterMyPlugin();
  
Bool PluginStart(void)
{
    if(!RegisterMyPlugin()) return FALSE;
    return TRUE;
}
  
void PluginEnd(void)
{
}
Bool PluginMessage(LONG id, void *data)
{
    switch (id)
    {
        case C4DPL_INIT_SYS:
            if (!resource.Init()) return FALSE; // don't start plugin without resource
            return TRUE;
        case C4DMSG_PRIORITY: 
            return TRUE;
    }
    return FALSE;
}

MyPlugin.cpp

#include "c4d.h"
  
#define ID_MYPLUGIN 123456789
  
class MyPlugin : public SceneHookData
{
    public:
        static NodeData *Alloc(void) { return gNew MyPlugin; }
};
  
Bool RegisterMySceneHook(void)
{
    return RegisterSceneHookPlugin(ID_MYPLUGIN,"My Plugin",PLUGINFLAG_SCENEHOOK_SUPPORT_DOCUMENT_DESCRIPTION,MyPlugin::Alloc,EXECUTION_EXPRESSION,0,NULL);
}

And my Errors (I use Visual Studio) :

Error	1	error LNK2019: unresolved external symbol "int __cdecl RegisterMyPlugin(void)" (?RegisterMyPlugin@@YAHXZ) referenced in function "int __cdecl PluginStart(void)" (?PluginStart@@YAHXZ)	Main.obj	plugintemplate
  
Error	2	fatal error LNK1120: 1 unresolved externals	plugintemplate.cdl	plugintemplate

Thank you for your help !
