This project is an example of how to point at clones as requested by @nicholse1 The Pointer sprite will always point at the closest Clone. Press <space> to move the position of the Pointer.
I have added comments within the project, so please "See inside" The basic idea is that all the clones have a cloneID which is a number to identify them by. To make this obvious I have given each clone a costume of its number. Each clone stores its X and Y positions in cloneX and cloneY lists. So clone 4's Y position is "item 4 of cloneY". To find the nearest clone we use Pythagoras theorem on the difference between the X positions of the Pointer and the Clone and the difference between the Y positions of the Pointer and the Clone, looping through the values in the lists. We then use a bit of trigonometry to calculate the angle between the Pointer and the nearest Clone. If you haven't covered Pythagoras or Trigonometry in Mathematics yet then you can either google it or just borrow the scripts and try and understand them later! :) As a comment on general coding style, please note there is just one "Green Flag" script with just one Forever loop. This prevents any initialisation or synchronisation problems ;)
