onBlockDestroyed

[Alix_The_Alicorn]

I want to execute some code when my item breaks a block, but in Item.class there is only a boolean called onBlockDestroyed. How would i run code on block destroyed?

[Draco18s]

You mean

 

public boolean onBlockDestroyed(ItemStack par1ItemStack, World par2World, int blockID, int par4, int par5, int par6, EntityLivingBase par7EntityLivingBase){}

[Alix_The_Alicorn]

yes I mean that method

[Draco18s]

So...what about it?

What is insufficient?

[Alix_The_Alicorn]

I want to run code when a block is broken. I have that code ready. How would I run it?

[Draco18s]

...put it in that function?

[Alix_The_Alicorn]

ok. but since it is boolean what do I need to return?

[Draco18s]

ok. but since it is boolean what do I need to return?

 

A...boolean...

 

True if the block is allowed to be destroyed, false otherwise.

 

If you don't know what you want it to do, specifically, you can always run your code and then do return super.onBlockDestroyed(...)

[Alix_The_Alicorn]

Ok, thanks for the help. Do you know what any of the params are though?

Hi Alix

 

If you are not sure what the parameters for a particular function are, the fastest way to find out is to look through vanilla code which uses the parameters and trace through until you either reach something you know or which has comments.

 

For example:

onBlockDestroyed(ItemStack par1ItemStack, World par2World, int par3, int par4, int par5, int par6, EntityLivingBase par7EntityLivingBase)

 

If you look in ItemShears.onBlockDestroyed, you see this...

 

par3 != Block.leaves.blockID

 

This tells you that par3 is the blockID.

 

In ItemSword.onBlockDestroyed, you see

 

Block.blocksList[par3].getBlockHardness(par2World, par4, par5, par6)

 

If you then go into Block.getBlockHardness, you see in the comments

    /**

    * Returns the block hardness at a location. Args: world, x, y, z

    */

so par4, par5, par6 are x,y,z

 

-TGG

I'm assuming I need to @Override it. To do what I need to do, I need an instance of entity player

(EntityPlayer par8EntityPlayer)

added to the boolean method. Is there another way to edit players inventory? I'm trying to set item damage to 1 if  a random integer == 1.

[Draco18s]

You don't need the player or the player's inventory.  The item they're using is already being passed to the function.

 

(And adding another parameter is not Magic, it won't make that reference suddenly show up)

[Alix_The_Alicorn]

Thanks guys a lot. here is my final method if anyone wants it.

@Override
public boolean onBlockDestroyed(ItemStack par1ItemStack, World par2World, int blockID, int par4, int par5, int par6, EntityLivingBase par7EntityLivingBase)
{

	final int x = 1;
	final int y = Reference.chiselBreakTime;
	int rand = new Random().nextInt(y-x) + x;

	if(rand == 2 && par1ItemStack.getItemDamage() == 0)
	{
		par1ItemStack.setItemDamage(1);
	}

	return false;
}

I'm testing it now
