I'm working on a new mod, but I've become insistent upon extending the progression tree. Doing this, however, would require modifying a few different enums as well as changing the properties of multiple blocks and items to match.
I have limited experience with Java, I do have experience, but not nearly enough to know how to modify these values.
What I want to do, explicitly, is this:
Modify harvest levels of blocks and tool tiers to insert new tiers in between for certain ores, creating a more Terraria-like progression
Potentially override vanilla values with modded ones, without forcibly prying into the vanilla values to modify them on loadup
Any clues as to how to accomplish either or both of these tasks?
