CS:GO Weapon Calculatorhttp://t-cote.ca/projects/csbuild/
As an avid gamer, I am always looking for tools that can help me better understand the underlaying mechanics of the games I am playing.
I got curious about the pros and cons of different weapons, and so I found a spreadsheet that had the details for all of the stats.
I combined this with spray pattern examples, a comparison tool, and a hitbox damages based on range calculator to make a very well rounded tool.
The tools I used were Angular, JSON, and LESS. It is a pretty adapative design (scaling to your screen size not using breakpoints) and took about 10 hours to build.
