Sphere around players in a GUI and making it interact with other spheres? [closed]

So I was trying earlier to get a working script in which the player would click a GUI button that would put a see-through sphere around the player and not affect the players movement at all. If the player came across someone else with their sphere on too, and their spheres touched, the two players would be launched away from each other.

I couldn't find a way to successfully spawn a sphere around the player in sync with the GUI, if anyone knows a way to do this is would be massively appreciated if they could show me how to do it. Thanks P.S I experimented with morphs and didn't get anywhere...
