I'm still new to modding and I have recently been re-learning Minecraft modding. 

 

The problem:

The bush block only spawns on stone. The tutorials online state that blockhelper is the way to fix this but it seems they have removed it. It would be nice if someone could help ne resolve this problem. Thanks in advance!

BlockHelper still exists, it's just called BlockMatcher now... I generate ores like so: https://github.com/SocraticPhoenix/Randores/blob/master/src/main/java/com/gmail/socraticphoenix/forge/randore/RandoresWorldGenerator.java#L70, but you just have to pass in a BlockMatcher.forBlock() argument as the last one in WorldGenMinable...
