Use multiple noise() instances within one class

in General Discussion • Other • 8 months ago

Hi,

I need to drive two lines contained in a class. I need some random shifting and I use noise(). If a call noise() and assign it to another variable it is moving the second line in parallel.

Probably pseydo-num generator is fixed within a class. Is there a way to overcome this? What are the suggestions from experienced programmers?

Thank you

Dimitris

Option 1: add something

float n1 = noise(frameCount*0.01+1);
float n2 = noise(frameCount*0.01+2);
float n3 = noise(frameCount*0.01+3);

Option 2: add something to the second dimension

float n1 = noise(frameCount*0.01, 1);
float n2 = noise(frameCount*0.01, 2);
float n3 = noise(frameCount*0.01, 3);

When you have a class you can generate a unique id/number within each instance that you add to the noise.
