Returns the list of bound parameters for the signal at [code]idx[/code]. Returns the number of signal connections in the scene. Returns the flags for the signal at [code]idx[/code]. See [Object]'s [code]CONNECT_*[/code] flags. Returns the method connected to the signal at [code]idx[/code]. Returns the name of the signal at [code]idx[/code]. Returns the path to the node that owns the signal at [code]idx[/code], relative to the root node. Returns the path to the node that owns the method connected to the signal at [code]idx[/code], relative to the root node. Returns the number of nodes in the scene. Returns the list of group names associated with the node at [code]idx[/code]. Returns the scene for the node at [code]idx[/code] or [code]null[/code] if the node is not an instance. Returns the path to the represented scene file if the node at [code]idx[/code] is an [InstancePlaceholder]. Returns the name of the node at [code]idx[/code]. Returns the path to the owner of the node at [code]idx[/code], relative to the root node. Returns the path to the node at [code]idx[/code]. Returns the number of exported or overridden properties for the node at [code]idx[/code]. Returns the name of the property at [code]prop_idx[/code] for the node at [code]idx[/code]. Returns the value of the property at [code]prop_idx[/code] for the node at [code]idx[/code]. Returns the type of the node at [code]idx[/code]. Returns [code]true[/code] if the node at [code]idx[/code] is an [InstancePlaceholder]. If passed to [method PackedScene.instance], blocks edits to the scene state. If passed to [method PackedScene.instance], provides inherited scene resources to the local scene. Requires tools compiled. If passed to [method PackedScene.instance], provides local scene resources to the local scene. Only the main scene should receive the main edit state. Requires tools compiled.
