Hands-on Rust: Missing code change to render the map with camera (page 113 in P1.0)
When introducing the camera, compilation errs as the change to the map’s render
method is not reflected in src/main.rs
, if just following the flow of the text.
Perhaps the next can just add the change on p113, from:
self.map.render(ctx);
To:
self.map.render(ctx, &self.camera);
In the state’s impl
of the GameState
trait.
First Post!

Thanks! Now that it’s in-print, I can’t readily make changes - so I’ve noted this down. If there’s a 2nd edition in the future, it’ll be included then.
