Run a script of process before each level gets built?

When you click build, before each level does get built, I want to run a script that will do a process to the entire scene before putting it into the build.

How would I go about doing that?

 

I don't think that's possible. The only thing I glanced from the reference that comes close to what you want is a isBuildingPlayer flag, but you'd probably need something like OnBeforeSceneBuild or something.

But why can't you make a component that does what you want in Awake or something?

 

You could create editor scripts that you run before you build that do what you want. I often process levels etc using editor scripts. It's a pretty powerful system when you get into it.

For instance on my current project I have scripts that load every scene process them save them and output them each as asset bundles.

 

That basically what I want to do. For pro this is easy. However I wanted to find a fairly automated solution for unity free.

Some funkiness: It gets called AFTER Awake().
