Hey out there.

I am trying to find out how to create new objects with COFFEE. Should be simple, but I can't seem to find any examples in the SDK or online forums.

I am trying to use AllocObject(), but can't figure out the syntax. I'm a newbie to COFFEE and I just need some help getting started. Any assistance would be much appreciated.

-Cheers

Go grab yourself the COFFEE documentation!

Since you are MacOS, get the HTML version, not the CHM Windows help file.

I have the documentation. I'm finding it a bit cryptic, and there are no examples of how to do what I want to do. AllocObject is not a member of BaseObject, understandably, but when I try the following:

var cam = new(BaseObject);

or:

var cam = new(AllocObject(Ocamera));

I get errors. I know that there is something basic about the object method that I'm just not grasping. I need help. Thank you.

I've tried this as well. I get an error, "Variable or function expected" at the type call to AllocObject.

Thanks.

Okay. What you may need here is this then:

  
var type = Ocamera;  
var cam = AllocObject(type);

I haven't used the 9.1 version of COFFEE yet, but the doc says ([int] type), so I expect that one cannot use the type directly. Examples of the changes in 9.1 would be warranted.

Robert, thanks for your help. I'm still geting an error though. At the end of the first line I still get, "Variable or function expected."

Something must be incorrect somewhere else then. My second message had the correct methodology. Here's a simple test source (MenuPlugin) - it loads an icon, so you may want to dump some tif or jpg image as the one mentioned in main() to avoid complaints. Also, use your own Plugin_ID for PLUGIN_MENU_ID.

This worked perfectly. Calling the plugin from the Plugins menu created a Camera object.

Robert,

Thank you so much for all your help. Your example was very useful as an addition to those that come with the SDK, so thanks.

I was still getting an error, and found that the real problem all along was that I hadn't installed the 9.102 updater from 9.012. So I had really been using the right syntax from early on, but the AllocObject() command was giving an error regardless. Now that I've installed the updater, everything is fine.

Sorry that I overlooked this, and thank you for taking time out to help me.
