How do I reintroduce a block in my mod class?

[TorchicBlaziken]

I want to change a property of a block that is defined in the Block class, but I don't know how to do that without editing the base class. There must be some way for Forge to remove it and then put it back in again.

 

The block in question is the pumpkin stem. I don't want to edit the BlockStem class, just change the FruitType of the pumpkin stem.

Google that.

I figured it out. The code I needed was:

 

		ModLoader.setPrivateValue(net.minecraft.src.BlockStem.class, (BlockStem)Block.pumpkinStem, "fruitType", realPumpkin);

For note, that will only work in MCP, not as an actual mod.
