I want to be able to have my LED lights flash green for a few seconds whenever I get a kill and flash red whenever I die. I am able to make my lights flash I just don't know how I'm going to be able to transfer a signal whenever I die/get a kill in the game. Any help would be greatly appreciated.
You could program a server which receives data from the game. According to the data you could program some LEDs to flash around. Here is a link to their developer page. Or you could use 3rd party site libraries which are also listed on their page at the bottom.
