I have added the functionality to be able to throw potion bottles at the barriers for the higher priority resources. After that I added in the ability to craft potions needed to get past barriers. To simplify things, the only projectile prefab that it getting thrown is a single potion prefab, but once you have crafted any potion, then just simply hitting its respective barrier will free the path to the resource. I also implemented a win condition to where if the player crafts the crystal potion, then a panel will come up saying you've won.
