<description>
|
|
Base class for all non built-in types. Everything not a built-in type starts the inheritance chain from this class.
|
|
Objects do not manage memory, if inheriting from one the object will most likely have to be deleted manually (call the [method free] function from the script or delete from C++).
|
|
Some derivatives add memory management, such as [Reference] (which keeps a reference count and deletes itself automatically when no longer referenced) and [Node], which deletes the children tree when deleted.
|
|
Objects export properties, which are mainly useful for storage and editing, but not really so much in programming. Properties are exported in [method _get_property_list] and handled in [method _get] and [method _set]. However, scripting languages and C++ have simpler means to export them.
|
|
Objects also receive notifications ([method _notification]). Notifications are a simple way to notify the object about simple events, so they can all be handled together.

Connects a [code]signal[/code] to a [code]method[/code] on a [code]target[/code] object. Pass optional [code]binds[/code] to the call. Use [code]flags[/code] to set deferred or one shot connections. See [code]CONNECT_*[/code] constants. A [code]signal[/code] can only be connected once to a [code]method[/code]. It will throw an error if already connected. To avoid this, first use [method is_connected] to check for existing connections.
