Hidden Shortcuts to Make Level Design Easier
Objective: Learn tricks inside of Unity to make Level Design easier.
So we are going to create levels in Unity, how about we learn some tricks that can help us in doing so ?

As we can see in the example above, we can simply select an object and drag a new asset into it. It will be located where our object is, and can give a different look to it.
The second way to make unique changes to your level is by creating multiple prefabs from your level’s elements.
We can start by creating a Prefab folder in our assets, and then just dragging our object to that folder and the file should convert into a prefab.

Now you can adjust the prefab look differently, and you will have a new unique element for your level. Please make sure to zero out your prefab after you have created it so that instead of having its positioning, it will be linked to the element you drag it inside of. You can, from here, drag and drop the prefab into other elements of similar sizes, take a few other elements, and do the same to vary your level look.
