Godot supports:

Mostly code

• create nodes, scenes, and connect everything in GDScript

Editor + code

• Visually place nodes in the editor, then write scripts.
• Faster for layout work.

Concept

• Everything is a Node.

  • Everything in a scene inherits from Node
  • Node (logic only)
  • Node2D (2D position/rotation/scale)
  • Control (UI)
  • RigidBody2D, CharacterBody2D (physics)

• A Scene is a tree of nodes saved as a .tscn file.

  • Scene files (.tscn) are plain text files. (a text description of a node tree)
  • Godot stores scenes in a human-readable text format.
  • Godot reads that text and builds the visual node tree from it.
  • Never need to manually edit .tscn files.

• main.tscn

  • The game's main scene.
  • Clicking main.tscn in Godot File System panel, will not show like normal code.
  • Godot will open the Scene editor

• .gd scripts

  • Behavior attached to nodes

• Scene Editor

  • Use to add nodes, drag things around, set properties.
  • Godot auto reads and writes that .tscn.
  • AI Agent will direct edit .tscn, the same effect as we click nodes in visual editor.

• Run the game

  • Godot parses all .tscn files and builds the actual game from them.
