To run the game, use
cargo run --features "vulkan"
on Windows and Linux, and
cargo run --features "metal"
on macOS.
For building without any graphics backend, you can use
cargo run --features "empty"
but be aware that as soon as you need any rendering you won't be able to run your game when using
the empty feature.
Notes:
Specs Docs: https://specs.amethyst.rs/docs/tutorials/01_intro.html
A system is nothing more than a function that runs once each frame and potentially makes some changes to components.
Improvements (Note: this is with the 0.13 docs while running with 0.12):
-
Explain the whole
#thing. -
What's with the use amethyst:: thing in the #?
-
Some of the # are wrong.
-
The specs links are dead. Point to new links.
-
amethyst::core::SystemDesc dne! (0.13 new feature!)
-
let mut world = World::new(); is not needed
