I read on the blog posts that Unity will upgrade assemblies to replace .rigidbody with a call to GetComponent.
Thats great, but what about a tool to upgrade existing c# scripts? According to the blog posts such a tool exists but I can’t find it anywhere. Are you using this tool or doing a find/replace on your C# scripts?
It’s been a while I used it but I think it appears in the Console as a Log Entry (with Warning Symbol), probably the very first or the last entry in the list. You need to double-click that entry, I believe the text mentions that too.
It’s in Tools/ScriptUpdater/ in my installation.
It runs when you import an old project automatically, and asks you for permission to update through a modal dialog. Don’t run it manually unless you know exactly what you are doing.
@RalphH , it did not run automatically. The project upgrade to Unity 5 threw some compile warnings in a plugin. I realize now that its waiting for me to fix those errors before running the tool. Thanks!
