Engine Basics

Reflection scope

• Happening inside of BVR_REFLECTION_BLOCK macro
• Runs once before main

Build scope

• Where Bvr::App initialisation is happening
• Runs once inside main
• Should be used to create resources, add plugins and schedule systems

Startup scope

• Happens once after Build Scope and is responsible for performing complicated engine/game startup logic.
• Is a schedule which can be constructed during Build Scope

Scheduled scope

• Happens after Build Scope is done

• Runs either:

  • Once if Bvr::App::RunOnce is called
  • Untill app is terminated if Bvr::App::Run is called

Initialisation

Core engine initialisation is happening inside of the Build Scope, where all plugins are added to the main application. A plugin must satisfy Bvr::Plugin concept. Inside the Build Scope it is also possible to set up runtime startup logic, Which could be dependent on some resources being created or some other piece of code previously executed. Startup system could be scheduled to the app with Bvr::App::AddStartupSystem .
