Shot Maps

Our team is in need of a shot map while scouting. The problem is, there are only two of us working on it and we can’t create a new app in the four weeks unitll competition. We have a scouting app that we have access the the source code to, but it is not nearly labeled enough to add this huge feature. Does anyone have already written code that we can use? It can be from 2016’s game, I just need a working one.
