Exporting variables to the editor

We have always defined variables within code and every time we wanted to change them, we had to change the code too. But in Godot, it is straightforward to expose variables to the editor so that we can change them without even opening the code editor. This is extremely useful when you want to test things out and tweak variables on the fly. An exported variable pops up in the Inspector view of that node, just like the transformation and text properties we saw in the Manipulating nodes in the editor section.

Important note
