Overview

This tutorial demonstrates essential pattern of the Lysa Nodes scene graph library : loading a 3D asset from a .assets pack file, displaying it through the deferred renderer with lights and post-processing, and animating it with a continuous, frame-rate-independent Y-axis rotation.

The tutorial source code is available at https://github.com/LysaEngine/lysa_tutorial_nodes_01.

Module

The nodes library lives in the lysa.nodes module:

import lysa.nodes;

This single import makes the entire public API available: Node, SceneTree, Camera, MeshInstance, AnimationPlayer, Environment, DirectionalLight, OmniLight, SpotLight, Timer, Viewport, and the physics nodes when a physics engine is enabled.
