So.. while working on Spawn 2.0 I got tired of writing this same sort of code over and over again : D. Ended up making a little scripty thing.
Normally collections are not boxed and their type is themselves. This may seem like a wonderful design, but for some cases it is not so wonderful =P, especially when you want to overwrite values and then undo those writes.
The goal of the script is to allow a struct to have values that can revert themselves. For example
and demo code
eh?
also you can do some very crazy objects
demo
I would specifically use this for mimicing data ^.^... for example, if you wanted a unit to mimic another unit for like a special Mimic spell that lasted bleh seconds, you could store the unit data, destroy your unit, and then clone the target.
If the target had like mimic health, you could overwrite health and w/e.
