Q: How to create a cube prefab asset?
A: The example script above won’t work until you assign a Prefab to the Block variable. To create a simple block Prefab:

Choose GameObject > 3D Object > Cube.
Drag the cube from the Hierarchy window into the Assets folder in the Project window. This creates a Prefab Asset.
Rename your Prefab to Block.
Now that your Block Prefab exists as an Asset, you can safely delete the cube from your Hierarchy.
