Does that mean 'if not' AND 'if and not' or 'if not' AND 'if true'?

You can test it in the Live demo too

Basically what MunkDev already described
Lua Code:
  1. if not IsMouselooking() and GetMouseFocus() == WorldFrame then
  2.     self.x = x
  3.     self.y = y
  4. end
Lua Code:
  1. not false and false -- false
  2. not true and false -- false
  3. not false and true -- true
  4. not true and true -- false
Truth table: not x and y
x	|	 xy
false	|	true		false	→	false
true	|	false		false	→	false
false	|	true		truetrue
true	|	false		true	→	false
