Why does a loop in MaxScript produce such a result?

Question

3ds Max

Good day everyone. Recently started learning scripting in MaxScript for 3d max and ran into the following problem:

s = sphere ()

for i=1 to 5 do
(
a=copy s pos:[i*50, 0, 0]
if (s.pos. x>150) then
(
s.pos.z=50
)
)

A small script that first creates a sphere, and then copies it 5 times through a loop, with the condition that when the X coordinate value becomes more than 150, then the Z position value must be assigned the value 50. As a result, the script simply makes 5 copies without changing the position in Z. Moreover, there is a slight oddity when I replaced the comparison operator with the reverse one, that is, (s.pos.x < 150), then one sphere still changed its position in Z=50, but the strangest thing is that it was the very first sphere , which was created at the beginning of the cycle, and how it took this value from the if statement is not clear to me at all ...

Answer 1

Replace s.pos with a.pos in two places
