[−][src]Struct bevy_app::App
Containers of app logic and data
App store the ECS World, Resources, Schedule, and Executor. They also store the "run" function of the App, which by default executes the App schedule once. Apps are constructed using the builder pattern.
Example
Here is a simple "Hello World" Bevy app:
use bevy_app::prelude::*; use bevy_ecs::prelude::*; fn main() { App::build() .add_system(hello_world_system.system()) .run(); } fn hello_world_system() { println!("hello world"); }
Fields
world: World
resources: Resources
runner: Box<dyn Fn(App)>
schedule: Schedule
