CSGO-Demos

A '20 summer project using Saul's NodeJS demo parser to take a CSGO .dem file and transform it into a feather dataframe for later use. Currently demo-parse.js accepts a .dem file and writes to a file that matches the name with a .out extension, enumerating all damage and kill events in post-warmup play. Then, python/clean.py accepts a .out file and reads it to a .feather file, which uses the pandas to_feather method to transform the pseudo-csv file (.out) to the feather format.

Example:

Blue spots represent locations where players died, and orange spots represent locations where players killed from.

Work Log

• Jun 8 First prototype completed for graphing a match played on CSGO's Overpass map.
  • Involves data flow from a NodeJS platform to generate a .out file that is faster to parse than the original .dem file, and a Python script to convert the .out file to a usable format (in this case, a pandas df -> feather format saved to file). A second Python script converts the feather file to a matplotlib plot. As of Jun 8, this process is only working on Overpass.
• Jun 14 Reformatted code into a single class file. The class expects a single .out file to be specified, and will generate a dataframe with an option for saving to a .feather format. See csgodem.py.
  • The class now parses the team names and map name from a properly generated .out file.
• Jun 26 Edited how metadata was generated (now in demo-parse.js) and added (readded?) the maps folder, now using CSGO's naming conventions (de_*)
  • When creating demo-parse.js, I found code from a different demo-based app that normalized locations in a demo to a given scale. In this case, I'm trying to normalize to a 100x100 scale (which is very easy to change later on). It seems, however, that the normalization fits perfectly for de_mirage and isn't meant for other maps. I'm going to stretch the extents to fit, which will hopefully allow me to develop a scale for later usage.
• Jul 7 Moved to Django for the web framework. Will eventually containerize the Django app and the NodeJS module separately. Currently working towards making a base site.
• Jul 8 Started working with ChartJS, but it seems that scaling a chart with a bg image (via css) isn't going to work well. Likely going to have the backend service a response with image addresses that showcase all of the possible options.
  • Made progress on exploring demo parsing via game events. Created demo-playground.js to showcase some examples (Useful link for CS:GO game events)
