Hands-on Rust: not all monsters destroyed on collision (page 140)

Hands-on Rust: not all monsters destroyed on collision (page 140)

After finishing the code at the end of Chapter 7 and running it, monsters sometimes don’t get destroyed on collision. Instead, the player disappears and only the monster displays until the two are at different locations again.

If I revert the code at the end of the “Moving Entities in a Turn-Based Game” section, I don’t see this behaviour.

I ran the downloaded sample code for that chapter and found the same thing.

Thank you! That’s not one I remember running into, but I’ll take a look. I’ve added it to the issue tracker, so if there’s another edition - it will be included in the “to fix” list. When I return from vacation, I’ll see if I can find the issue - if I can, I’ll put a bug-fix up on hands-on-rust.com.

I believe the problem is that on p138, build_monster_scheduler() is missing:

.add_system(collisions::collisions_system())
.flush()
