Advanced Development using DVN
======

This document describes advanced features of DVN and how to use them.

This document is a WIP and each entry is a placeholder.

Frame Loop & Loop Overrides
==============

how the frame loop is structured

how to inject logic before/after render

how to modify rendering per-window

recommended use cases

performance considerations

Multi-Window / Multi-Instance Support
==============

how to create extra windows

how rendering differs between them

how to sync states between windows

use cases (debug tools, second viewpoints, HUD windows)

Custom Rendering Pipelines (OpenGL, 2D/3D, Overlays)
==============

drawing your own objects

hooking OpenGL directly

layering effects

injecting shaders

replacing DVN's renderer

Networking (Multiplayer / Streaming)
==============

high-level approach

recommended architecture

how VNs sync story states

streaming assets

multiplayer story use cases

Script Data Injection (injectGameScript)
==============

how it works

how to transform script keys

use cases

modding support

auto-translation hooks

AI-generated content injection

dynamic branching

analytics tags

safety considerations
