View Full Version : example of SendModelingCommand()?
10-13-2005, 05:18 PM
I'm trying to figure out how to use the SendModelingCommand() function to create a simple COFFEE plugin, without much luck. Here's the body of my Execute() function:
SendModelingCommand(MCOMMAND_JOIN, doc, doc->GetActiveObject(), new(BaseContainer), MODIFY_ALL);
The plugin loads fine, but I get the following error when I try to execute it:
(5) Incompatible values... NIL / OBJECT
Objects are definitely selected in the document when I try this.
Any idea what might be going on? Thanks.

you don't need doc->GetActiveObject, just use "op" that's what the active object is. and make your variables/objects outside of the command, i.e. don't put new(BaseContainer) in the command. make a new basecontainer outside i.e.
then use that inside of your command.
for debugging in general it's always best to not concatenate stuff until you're sure it works.

Hmm...op doesn't seem to be available as a variable. Maybe because it's a plugin file rather than a COFFEE expression? I've implemented the rest of your suggestion but the error message hasn't changed. Here's the latest:
var myob = doc->GetActiveObject();
var bc = new(BaseContainer);
SendModelingCommand(MCOMMAND_JOIN, doc, myob, bc, MODIFY_ALL);

your execute should probably read
you should then check that op or if you keep it as is the myob exist i.e. if (!op) return; etc

If I add the op parameter to Execute(), I just get a "too many parameters" error when C4D loads the plug-in...so I don't think that can be it.
And I agree that I should do some error-checking, but I thought I'd focus on getting the core code working first :-p.
Any other ideas? Is there any chance this has something to do with the fact that MCOMMAND_JOIN would need two or more objects to join?
