copy to points - variant issue

[davidyannick]

I try to use variant and each time at point 0 as always the same variant, even when I change the seed ? any idea ? thanks

Salut David,

it's weird indeed. I bet it's from the random function at ZERO.

Here is one way to go around the problem:

just replace the multiple by your seed (*) by an addition (+) then it should avoid the zero, and solve your problem

 

i@variant=int(fit01(rand(@ptnum+chf("seed")),0,3));

instead of :

i@variant=int(fit01(rand(@ptnum*chf("seed")),0,3));

you're right  thanks for your help

if you want to be safer and also to avoid increasing seed by increments of 1 just offseting the same random number to the next point you can use 2 dimensional rand(float, float) 

i@variant=int(fit01(rand(@ptnum,chf("seed")),0,3));
