Module bevy::app::prelude

Structs

• App
  A container of app logic and data.
• First
  Runs first in the schedule.
• FixedFirst
  Runs first in the FixedMain schedule.
• FixedLast
  The schedule that runs last in FixedMain
• FixedPostUpdate
  The schedule that runs after the FixedUpdate schedule, for reacting to changes made in the main update logic.
• FixedPreUpdate
  The schedule that contains logic that must run before FixedUpdate.
• FixedUpdate
  The schedule that contains most gameplay logic.
• Last
  Runs last in the schedule.
• Main
  The schedule that contains the app logic that is evaluated each tick of App::update().
• PostStartup
  The schedule that runs once after Startup.
• PostUpdate
  The schedule that contains logic that must run after Update. For example, synchronizing “local transforms” in a hierarchy to “global” absolute transforms. This enables the PostUpdate transform-sync system to react to “local transform” changes in Update without the Update systems needing to know about (or add scheduler dependencies for) the “global transform sync system”.
• PreStartup
  The schedule that runs before Startup.
• PreUpdate
  The schedule that contains logic that must run before Update. For example, a system that reads raw keyboard input OS events into an Events resource. This enables systems in Update to consume the events from the Events resource without actually knowing about (or taking a direct scheduler dependency on) the “os-level keyboard event system”.
• SpawnScene
  The schedule that contains scene spawning.
• Startup
  The schedule that runs once when the app starts.
• StateTransition
  Runs state transitions.
• Update
  The schedule that contains app logic. Ideally containing anything that must run once per render frame, such as UI.

Traits

• Plugin
  A collection of Bevy app logic and configuration.
• PluginGroup
  Combines multiple Plugins into a single unit.

Derive Macros

• DynamicPlugin
  Generates a dynamic plugin entry point function for the given Plugin type.
