Hot Reload

[ScottKane]

How do you achieve hot reloading in UE5? Are you just using cargo-watch or hot-lib-reloader to do this in you demo videos or should this just work out of the box?

I should add some docs for it

cargo watch -i "example/*" -s "cargo build --release && cp target/release/slash_example.dll example/Slash/Binaries/rustplugin.dll"

This is currently what I use for my next sample. Basically you just compile your project and copy the new dll to the Binaries folder. Unreal-rust will then hot reload it.

Awesome thanks

Also if you use nightly you can use --out-dir to copy the output dll to the binaries folder as a final step in the build
