Quick tip: if you’re not a fan of the boilerplate code that Unity spits out when you create a new script (for example, if you’d rather have an
OnGUI function ready to go rather than
Start), you can easily change it to whatever suits you best. In Mac OS X, right click on the Unity application, choose “Show Package Contents,” and navigate to Contents → Resources. You’ll see three files named NewBehaviourScript. Open those up, modify them to your liking, and save.
