You're trying to use your question and its answer as a discussion but that's not how these sites work. Your starting point is simply too far away from the answer you need which is why when each point is solved you move onto another problem in the comments.
The fact that your first question was closed as too broad is highly indicative of that.
What you need to do is your own research, spend some time understanding the subject by doing tutorials or reading documentation. Try to solve the issues yourself and thereby understand how to break your problems down into component parts some of which you may solve and others which eventually may make good questions.
One of the answers does suggest that the "jitter problem" that you'll come across the moment your current problem is fixed is well known and solved in other questions and answers, which you can find by searching on your own.
Eventually the answerers do realise that the amount of hand holding you need is simply not worth it, there are other questions they can answer or other things entirely they need to do so questions that end up requiring a lot of back and forth rarely if ever end well. If it takes more than an hour of back and forth in comments to help you, how many other people could have been helped instead? In the most mercenary terms, how much rep are you asking them to forgo by doing that? The best you can offer is to accept one answer but you haven't shown any sign to the answerers that that is likely to happen anytime soon with either of your questions.
