Detailed Description

NodeComponent is the base class for all node components.

Node component is an isolated piece of logic which can be attached to any node in order to add additional functionality to it. Examples of node component could be Trigger which performs specific actions when certain conditions are met or AnimationPlayer which animates specific properties of the node it is attached to and its child nodes.

Node component can only be attached to a single node at a time. After node component is detached from one node, it can be attached to any other node.

Node component starts to perform its logic after it is attached to a certain node by calling its attach() function. After node component is detached from its node by calling its detach() function it becomes inactive and stops to perform its logic.
