I'm trying to check to see if a block at some co-ords is equal to either air or to water. However, even if it is air, it still returns true. Any help please? I'm a bit confused.

 

    private static boolean doesBlockExist(int x, int y, int z){
	if(Minecraft.getMinecraft().theWorld.getBlock(x, y, z) == Blocks.air){
		System.out.println("Block: " + Minecraft.getMinecraft().theWorld.getBlock(x, y, z));
		return false;
	}else if(Minecraft.getMinecraft().theWorld.getBlock(x, y, z) == Blocks.water){
		System.out.println("Block: " + Minecraft.getMinecraft().theWorld.getBlock(x, y, z));
		return false;
	}else{
		System.out.println("Block: " + Minecraft.getMinecraft().theWorld.getBlock(x, y, z));
		return true;
	}
    }

 

-- EDIT --

I have fixed the code thanks! For anyone who is having the same problems, you need to use the server side world, which you can get from the EntityPlayerMP via

 player.worldObj 

You really need static and cant you get world another way?

 

Well it's probably because you are using the client side world. Where is this method?
