Boolean position of a point

I want to have a point that belongs or not to a straight line dependanding on a boolean value. I tried

(4.54, -1.82) a + (1 - a) Point(f)

in the definition of my point, where (4.54, -1.82) is the curent random position, a the boolean name, f the straight line. But it does not work.

Any other idea ?

Solution

  • you must know that a boolean is not 0 or 1 , it's take true or false , so create an integer called n and write this : n=if(a,1,0) then u can complete ur work as 

    (4.54, -1.82) n + (1 - n) Point(f)

    otherwise i don't know
