I wanted to create a block, that will destroy a world, so I can balance out the OP stuff that I have in my mod. For example, I created a very valuable ore, and it is rather OP, so if I make it only generate in the "corrupted biome" and then if the player didn't get to it fast enough, they would lose it to the "corruption block". I have already got a timer working (one that will initiate the spread code, every couple of ticks (it chooses a random integer between 0 and 250), then will tick up to it. When it reaches the integer, it will reset the counter, then choose another integer.) It will also call the spreading code.
I was wondering, now I have this, how can I make it check for and replace blocks.
Any help is much appreciated.
