The built in plugins/behaviors are those that comes with C2. (The mouse, sprite, text, textbox objects, etc...)
If you haven't downloaded any third-party plugin from the plugins forum, then all your objects are allowed except the four we already mentionned.
You can find the full list of built-in plugins in the manual's plugin reference part
. Any other plugin is a custom/third-party plugin.
I'm not saying such a list wouldn't be implemented. I'm just pointing out how to workaround in the meantime, until this feature gets added, if judged adequate by @Tom when he'll have the time to implement it.
Tom's todo-list is as long as Ashley's.Kyatric2012-01-03 13:18:41
