Tower Builder
Part of the Unity Scripting Basics section of Coddy's Unity journey. Lesson 84 of 85.
A crane slides back and forth above a base. Each press of Space, or each click, drops a block straight down from the crane. A block that comes down on top of the stack stays there, and the next block has to land on it. A block that misses falls away. The height of the stack is the score.
Write the whole game in one script, Crane, on the crane.
Challenge

Transform fallingfield, only whilefalling == null. - Move the falling block down at
fallSpeed.
Press Play and press Space: a block falls from the crane. Then Check.

[SerializeField] private Transform top;
[SerializeField] private float craneSpeed = 3f;
[SerializeField] private float craneEdge = 4f;
[SerializeField] private float fallSpeed = 7f;
