Looking to award quickly, don't see this taking more than an hour or 2, (send me a chat)
Unity 3d Project Example
1. In the Scene there is a cube primitive size 1x1x1.
2. Write and comment so I know what you are doing C# code:
Every time the mouse is clicked the cube will appear in that spot but at a random size between .5 and 2.
Also a "shadow cube", the exact size but a grey shade, will be left where the old cube was.
When the program is ran every click moves the 3d cube to the new coordinates, and through the code a new cube is created to replace it.
I DO NOT want something that just creates a new cube where the mouse clicks and colors the old one gray.
