+ Returns whether the [code]mouse_position[/code] is in the input hot zone.
+ By default, a hot zone is a [Rect2] positioned such that its center is at [code]graph_node[/code].[method GraphNode.get_connection_input_position]([code]slot_index[/code]) (For output's case, call [method GraphNode.get_connection_output_position] instead). The hot zone's width is twice the Theme Property [code]port_grab_distance_horizontal[/code], and its height is twice the [code]port_grab_distance_vertical[/code].
+ Below is a sample code to help get started:
+ [codeblock]
+ func _is_in_input_hotzone(graph_node, slot_index, mouse_position):
+ var slot_size : Vector2 = Vector2(get_theme_constant("port_grab_distance_horizontal"), get_theme_constant("port_grab_distance_vertical"))
+ var slot_pos : Vector2 = graph_node.get_position() + graph_node.get_connection_input_position(slot_index) - slot_size / 2
+ var rect = Rect2(slot_pos, slot_size)
+
+ return rect.has_point(mouse_position)
