Drawing a Circle with range (HELP!!!)

Hello,

I’ve been working on a TD game and I really need to make the player see the range of the tower he is clicking at (the towers can level up so their range increase). What I want to do is draw a circle around the tower showing the range everytime I click at it.
How should I do it? Tried to apply a texture of a circle but the circle is always changing size based on the range…

ps: Im working with javascript.

Thanks in advance!

Yes, it’s something like this, but i need to use it using 3d coordinates not screen coordinates… i will try to adapt it somehow!
