I've encountered a weird generation issue with my custom gems' ores. When I first added them, I used an array of Block to initialize them and a 'gemNames' string array, with the names of each gem in it (like this). Then I just added the WorldGenerator code, with the same parameters for every gem (with the exception of the Block parameter).

 

This made only the first one generate. I was puzzled, so I removed the ruby generator (commented it out). Then only citrine generated. So I changed the parameters of each generator to be different (here), and then they worked... sorta.

 

The problem is that they generate on the same X and Z coordinate, but different Y. This is strange because my other generators (this) work just fine and don't stack vertically.

 

Anyone have any idea what's going on?

Hmm... so I've changed the code around a bit, but it's still generating as before. I really don't know what's wrong .

It's time to set a breakpoint and walk through your generator in the debugger. See what's happening with your randomizer (you may want to articulate your code so you can examine subexpressions). Also find out where the random is coming from.
