Unity hotswapping notes

Unity has built-in support for hotswapping, which is a huge productivity booster. This feature works not only with graphics assets like bitmaps and meshes, but also with code: if you edit the source and save it, the editor will save the state of the running game, compile and load the new code, then load the saved state and continue where it left off. Unfortunately, this feature is very easy to break, and most available 3rd party plugins have little regard for it.

It looks like there’s a lot of confusion about hotswapping in Unity, and many developers are not even aware of its existence – which is no wonder if their only experience is seeing lots of errors on the console when they forget to stop the game before recompiling... This document is an attempt to clear up some of this confusion.

Nota bene, I’m not a Unity developer, so everything below is based on blog posts and experimentation. Corrections are most welcome!

The Visual Studio Tools for Unity are able to convert .NET debug symbol files (namely pdb files) to debug symbols files that are understood by Unity's scripting engine (namely .dll.mdb files) when importing both the .dll and the .pdb in the Assets folder.

If you prefer to handle the conversion yourself you need to call a tool named pdb2mdb on the .dll associated with the .pdb:

pdb2mdb MyLibrary.dll

Will produce a MyLibrary.dll.mdb usable on Unity if MyLibrary.pdb is present.

        var leftUp = new Vector2(-camSizeWidth, camSizeHeight);

Go to Bitbucket and create a new repository (its better to have an empty repo)
    git clone [email protected]:abc/myforkedrepo.git
    cd myforkedrepo

Now add Github repo as a new remote in Bitbucket called "sync"
    git remote add sync [email protected]:def/originalrepo.git

Verify what are the remotes currently being setup for "myforkedrepo". This following command should show "fetch" and "push" for two remotes i.e. "origin" and "sync"
    git remote -v
