Sets a vector's magnitude to a given value.
The static version of setMag(), as in p5.Vector.setMag(v, 10), returns a new p5.Vector object and doesn't change the original.
Examples
Syntax
setMag(len)
setMag()
setMag(v, len, [target])
Parameters
len
Number: new length for this vector.
v
p5.Vector: the vector to set the magnitude of
target
p5.Vector: the vector to receive the result (Optional)
Returns
p5.Vector: v with a magnitude set to len
