-- This helps dramatically with development, as we don't have to restart Noita for every change.
|

-- To accomplish this, we need to override the default behavior of dofile and some other things.

---Overwritten dofile to execute a lua script from disk and cirumvent any caching.
|

---Noita for some reason caches script files (Or loads them into its virtual filesystem)(Or caches compiled bytecode), so reloading script files from disk does not work without this.

|
|
---This is not fully conform the the standard lua implementation, but so isn't Noita's implementation.
