Change vanilla block drop using special item (pickaxe)

[Fashi]

Hey! I want to make pickaxe which you can dig glass and glass pane and you get glass or glass pane like Silk Touch enchantment. How to do that? I don't want to change BlockGlass.java. I want to do it also with gravel but i think it will be the same.

 

Code:

package Test.common;

import java.util.Random;
import net.minecraft.block.Block;
import net.minecraft.block.material.Material;
import net.minecraft.entity.EntityLiving;
import net.minecraft.item.EnumToolMaterial;
import net.minecraft.item.ItemPickaxe;
import net.minecraft.item.ItemStack;
import net.minecraft.world.World;
import net.minecraftforge.common.IShearable;


public class ItemWoolPickaxe extends ItemPickaxe 
{
public ItemWoolPickaxe(int par1, EnumToolMaterial par2EnumToolMaterial)
{
	super(par1, par2EnumToolMaterial);
}
public String getTextureFile()
    {
    	return "/woolpickaxe.png";
    }
public boolean canHarvestBlock(Block par1Block)
{
	return par1Block == Block.glass && par1Block == Block.thinGlass;
}
public float getStrVsBlock(ItemStack par1ItemStack, Block par2Block)
{
	if(par2Block.blockID == Block.glass.blockID || par2Block.blockID == Block.thinGlass.blockID)
		{
			return 7F;
		}
	else
	return par2Block != null && (par2Block.blockMaterial == Material.iron || par2Block.blockMaterial == Material.rock) ? this.efficiencyOnProperMaterial : super.getStrVsBlock(par1ItemStack, par2Block);
}
}

I think your best bet would be to look into Java reflection and change how the block is dropped when beaten to oblivion by your new pick.

I'm afraid of my mod will be incompatible with other mods.

as long as you don't modify any base classes, it should be compatible.

Not sure if this is the proper way to do it but its what works for me, "onBlockDestroyed" I check what block it is then, I set the block to 0 and then spawn a entity item were the block was. Since its glass really just spawn the entity.
