My last hurdle with DragCore is getting the Game Center / Google Play Game Services functionality working. Every time I try to activate achievements o leaderboards the game crashes. A very annoying type of roadblock. Today I'll be re-watching setup tutorials and tracing my steps to make sure I'm not overlooking something.
Something I can talk about here though is how I prepared achievements and leaderboards for the first time. It was an interesting experience and I hope to better take advantage of these tools in the future. Details are below the page break.
