I was struggling with how to make a a battle system for my current game so I went barebones and made this. Hopefully it may help a person or two.
It's basically you walk into either enemy - encounter that specific enemy. Every enemy shares a health variable which is set upon walking into them.
If there's an easier way let me know! but anyone who was also struggling, take a peak.
