Drag and drop objects in unity, and the wheel controls the effect of the object's proximity

Add a Cube object and mount the script in the scene, in addition to the default camera and light.

It is worth noting that the Screentoworldpoint method does not assign a value to the z-axis, so you need to assign a value to the z-axis yourself. V.z is not the z axis of the cube but the distance between the camera and the cube.
