Take a look at http://www.wuppy29.com/minecraft/1-8-tutorial/updating-1-7-to-1-8-part-3-basic-blocks/#sthash.Yyem8Bz7.dpbs. I found it rather helpful and his other 1.7-1.8/1.9 stuff is pretty good as well.

Thank you for the information and recommendation. I was able to dig deep enough to find out how one might do that through forge. That in conjunction with Cloning the Random class I should be able to do what I need to do.

Hello All, I'm looking into implementing a mod that shows possible spawner locations. Something along the lines of for use with identifying some behaviors within Vanilla MC. Implementation details aside. I have identified the classes that need I need to modify or hook into. I need to make some tweaks to net.minecraft.world.gen.feature.WorldGenDungeons.class and net.minecraft.world.gen.ChunkProviderOverworld.class to get the needed information for rendering. WorldGenDungeons has a hook, but I can't use it without querying the Random class which changes the results of the actual generation (Something I am explicitly avoiding). As such, I need to modify the code for Forge or Minecraft directly to get the information without changing the state. How would I go about doing this? The best I can come up with is jar modding Forge itself, but that seems wrong on multiple levels. It seems like there must be a better way. Any pointers? (If you'll pardon the programing pun...)
