Combination Tool [Help]

[JohnBeGood]

How would I go about making a combination tool? A tool that could be a pickaxe and a hatchet, or a pickaxe and a shovel, or any combination.

 

I currently tried using a method where it can harvest all blocks except ones listed like this [for a pickaxe and shovel combo] but it is able to harvest all 3 types effectively:

 

@Override
public boolean canHarvestBlock(Block par1, ItemStack itemStack) {
	boolean isHarvestable;
	isHarvestable= (par1 == Blocks.bedrock || par1 == Blocks.log || par1 == Blocks.log2);
	return !(isHarvestable);
}

Still unsolved.

To debug this sort of issue, I add a lot of System.out.println() statements to help trace the code to confirm if it is doing what I expect.

 

For example, if you change the code to the following:

@Override
public boolean canHarvestBlock(Block par1, ItemStack itemStack) {
    System.out.println("Executing canHarvestBlock() method, block parameter = "+par1.getUnlocalizedName());
    boolean isHarvestable;
    isHarvestable= (par1 == Blocks.bedrock || par1 == Blocks.log || par1 == Blocks.log2);
    System.out.println("isHarvestable ="+isHarvestable);
    return !(isHarvestable);
}

 

It should tell you whether the method is being called at all, tell you what block was passed to the method, and what the isHarvestable value got set to.  That sort of information usually helps you figure out where the execution is going wrong.

In a perfect minecraft world, you write something like this:

class MySpadePick extends Tool implements Pickaxe, Spade
{
   @Override
   pickaxe methods...
   @Override
   spade methods...
}

But, you cannot. Minecraft isn't written that way.

From this I can tell it isn't getting called period.
