Hm, as the things were not working in Coffee I switched over to C++. And now I'm stuck. I've cleared out the SDK Examples to fit my needs, I was able to reuse my GUI - well, at least it shows up when I start the plugin. But I have no clue how to start from here. Could someone just give me a start - lets say how is the code to create a simple object, a sphere or a camera or something?
I always seem to get lost in the sdk example files :(

Thanks

You might get lost in the SDK examples but just keep going over it. About 90% of what you can do is covered in the examples somewhere. Eventually everything will click into place.

Also, you might want to use the search. This subject has been mentioned before.

I'm assuming you already have a basic plugintype and you just need to create an object. This is very easy to do with SDK

Here a few examples

  
AutoAlloc<BaseObject> MyObject1(Ocube);  
AutoAlloc<BaseObject> MyObject2(Onull);  
AutoAlloc<BaseObject> MyObject3(Osphere);  
  
// Add the objects into the document  
GetActiveDocument()->InsertObject(MyObject1,NULL,NULL);  
GetActiveDocument()->InsertObject(MyObject2,NULL,NULL);  
GetActiveDocument()->InsertObject(MyObject3,NULL,NULL);

I thought I had some basic plugintype - the plugin is already registered in the menue and opens up a GUI, but I don't know where to go from there. Where do I put the code you gave me?
I basically changed the SubMenue Example, so I have a main.cpp which just openes a test.cpp and this is the former sub menue example, just changed to load my test.res file.

I've made a switch and hoped it would work there but sadly it doesn't

Where to put the code actually depends where you WANT to put it. The most easiest is to put it in the CommandData::Execute method

which I am guessing is where you have your code to open the GUI you have created

take from the SDK examples:

  
Bool MenuTest::Execute(BaseDocument *doc)  
{  
AutoAlloc<BaseObject> MyObject1(Ocube);  
AutoAlloc<BaseObject> MyObject2(Onull);  
AutoAlloc<BaseObject> MyObject3(Osphere);  
  
// Add the objects into the document  
GetActiveDocument()->InsertObject(MyObject1,NULL,NULL);  
GetActiveDocument()->InsertObject(MyObject2,NULL,NULL);  
GetActiveDocument()->InsertObject(MyObject3,NULL,NULL);  
     //ControlThread ct;  
     //ct.Start(FALSE); // multiprocessing test  
  
     return TRUE;  
}  

Then clicking on the plugin in the plugins menu will create 3 objects in the docuemnt

Hm, nothing happenes.
Yes, have the code to open the gui in the "Execute" function, but when I put your code here (with or without disabeling the open gui code) nothing happens.
I've already tryed to erase the whole function and replace with yours bot no success.
But it compiles without error.

Try putting a breakpoint or a GePrint() to verify that the code is actually run. Also, you should probably have an EventAdd() to make the editor update afterwards.

Hm, thanks guys, I've found a solution, it just needed some time and a programmer with some spare time on my side to get me started. ;)
