Expression error trying to rotate z using index

[James Peres]

Hi, not sure what you are trying to do exactly, but 10/5 % 1 would be 0.02, so I don’t think it will work the way you want.

Also, I would personally put t=0 before everything, and then put the t=[whatever] in braces, then not put t in brackets. There may be some quick shortcuts I’m not sure about but I just stick to the basic syntax.

Hi James,

Thanks for your response. Unfortunately, changing the code did not change the result (updated code included).

The statement to get the “num” variable works as expected (btw, (10/5 % 1) will be 0 as the remainder of (10 divided by 5) divided by 1 is 0). The problem seems to be with the conditional statements. And the error doesn’t appear until the sixth layer in the comp upwards.

Thanks,

Jack

num=(index/5 % 1);
t = 0;
if (num==.2) {
t=-60
};
if (num==.4) {
t=60
};
if (num==.6){
t=-120
};
if (num==.8){
t=120
};

t

You can try with a switch over index%5 (equivalent, but simpler than index/5 % 1):
switch (index%5){
case 1 : t =-60; break;
case 2 : t = 60; break;
case 3 : t = -120; break;
case 4 : t = 120; break;
default : t = 0;
};
t;

Edit : It is quite risky to compare non integral numbers…
You can try this: open the javascript editor (File>Scripts>Open Scrip Editor), type the line:
6/5 % 1;
press ‘play’ (top right area of the editor window).
The result appears in the bottom row of the window : 0.2
Now replace that one line code by
(6/5 % 1) == 0.2;
and press play again. Result ….. false 😉

Xavier,

This works perfectly. I didn’t even know the “switch” statement existed. Must read up on it.

Thank you very much!

Jack
