Godot 3 dialogue plugin using NodeGraph. I learned a lot from making this plugin, but it grew out of scope and there are way better solutions with a lot more work behind them.
Node Tree System:
Node Editor:
It's separate from the tree editor in the same dock as the inspector, allowing it to be resized individually
Character Resource:
Start: Defines the first node in the tree, you can choose the character's starting positions and expressions. There is no exit node, if a node is not connected further (no right socket connected) it will end the dialogue.
Sequence: Most node based dialogue editors force you to make a new node per character line, the sequence node instead allows you to make as many lines as you need with all available characters.
Choice: You can make a character ask a question, then add as many answers as you need. Each answer will add a new socket to the node for branching connections. The red left one is for inserting condition nodes.
Condition: Can only be connected to red sockets, they block branches with variables comparisons. Typically used for item checks or stat checks in RPGs
You need two nodes
The dialog node just holds a reference to the dialogue resource you want to play, and a reference to the dialogue player. Use start_dialog() as you like to play the dialogue file.
The dialog player node is a premade scene that contains all possible character positions and the dialogue box. You need to define which input action will advance the dialogue in the inspector.
