A simple way to get players at the start of a period

[pxpwoa]

There is a sample way of using API of NBA.com to return the the players playing in initial seconds of period, like this api to return the start of 1st period: https://stats.nba.com/stats/boxscoretraditionalv2/?gameId=0041700404&startPeriod=0&endPeriod=14&startRange=10&endRange=240&rangeType=2 startRange must be setted to greater than 0.

So this is how I do it in my data pipeline. The issue is that it does not account for corner cases. The endpoint will not return a list of players if there is not an event inside of that range. There are also cases where a substitution happens in that range, or where the api only returns 3 or 4 players. As you go further back in time, this method becomes less and less reliable. I decided to go the route I went in the tutorial instead of this route so that the reader didn't have to delve into all of the strange corner cases and write a bunch of special code to handle them.

You are right. Some corner cases will impact the accuracy of the way I suggest. As I focus on the realtime analysis of the game, I am intersted in looking the way can calculate the possession at the beginning of the quarter, instead of after that. I will check the way I suggest, and look for the way to fix the problem of reliablility.

I've found the best way is then to find first N events, use time constraints based on the time of those events. If any are subs then apply subs appropriately.

It looks like that the project is not working in the game early, like 0011300108,0011300115.

interesting, i'll look into these two tonight.

Found the bug with those two. Also realized I was still using advanced boxscore instead of traditional
