I want a simple ECS system for my meshes, lighting, and camera

Scenes and Nodes

• Scene is the basis for a game level/world
• Structure of the scene is tree-like, where the Scene is the root
• Nodes are nodes in the scene tree
• Nodes have to propagate:
  • Transformation (hierarchical transformation)
  • Input events
  • Frame event
• We can have as many nodes nested in a node and as deep as we want
• Nodes have their own properties, some of which can be seen and edited in the editor

Custom nodes

• User can create custom nodes from pre-built nodes
• Custom nodes can be used similarly to built-in nodes

Serialization

• Each scene can be serialized containing information of all nodes in it
• Custom node can be saved to disk, but its information in the scene will be stored in the saved scene
