thank you for the fast answer, this helped me a little bit.
But because i want to use it for a game, i have to change it a little bit.
At the moment, i can select with left click a player and see the range he can move.
With right click i'm able to unselect the player.
My Problem now is, i don't know how to make him move, that the range will be unselected after he moved.
There are some Sprites i didn't use, just to trying around.
I hope you or other People from the Community can help me.
