While this same concept can be used in 3D projects just as easily, this particular project will be using 2D objects to accomplish its goals. Next, name the project Extending Unity and be sure to set it as a 2D project. To begin, launch Unity and click the New button to start a new project as shown in Figure 1. In this project you’ll create a simple Unity extension that will gather all objects of a certain tag and set both a random color to each individual object as well as allow you, the user, to change the size of the objects all at once in just a couple clicks. Fortunately, there is a third option available thanks to Unity extensions, and of course the process of creating your own extensions is made relatively simple. Surely there’s another way to do the same task.

This can be very tedious and time consuming if you have a lot of objects to change at once. From one scene to the next, they’ll all be the same.Īnother method is to alter the values of variables in the Inspector window in Unity, but this would require going to each individual object and changing whatever values you would like changed. One way to change an object is through scripting, but there’s a problem with that method all objects that use the same script will apply those same properties. Typically, you only have two methods of changing an object’s properties. For example, they may need to be a different size than the previous monsters.

Now suppose that in another scene you need the same monster objects from the first scene, but they need different properties from the monsters in the previous scene. Pretend for a moment that you’re working on your game, and you need to have monster characters placed throughout your scene.
