Title: Hands-On Rust: (Chapter 8 - Waiting as a Strategy)
After following the instructions in the text (as I read them at least, there is some ambiguity as to the placement of some code), pressing a non-movement key did not result in monsters moving.
To troubleshoot, I compared to the source text and found the following differences between my source, and the results of making changes in the book:
– I needed to remove
if turn_state.clone() != TurnState::AwaitingInput {
return;
}
at the top of the function.
– needed to move the let (player_entity,destination query outside of the if delta... if statement.
– had to ensure that the if !did_something if statement was outside of the if delta... if statement.
Maybe I missed something earlier on (perhaps added in beta 2, I’m not planning to start from scratch with each beta release 
), but a cursory search didn’t find where I missed these details.
