Using generateData, what is difference between passing true or false. #100

Hi ! Forgive me for asking this simple question ~ I read the source code, but still confused.

I saw the projects that some use ENV.generateData(true) or can use ENV.generateData(false) , so what is the mainly difference between passing true and false ?

It seems that use false repaint is faster than use true generateData ? And is using true will take up more memory ?

ENV.generateData(true) will keep all generated object identities, it is useful with framework like Angular that checks object identity to trigger repaint.

ENV.generateData(false) regenerate everything each round.
