Making vanilla blocks drop items without editing base classes

[Thor597]

I was wondering if there was a way to make vanilla blocks drop items without editing the block file. In my case I want to make ice drop salt (from my mod) at a 1-10 chance without editing BlockIce, is there a way to do this?

[Thor597]

Please I need help!

Java reflection is useful because it supports dynamic retrieval of information about classes and data structures by name, and allows for their manipulation within an executing Java program.

 

If you don't understand how that could be helpful, then you are probably copy / paste "modding"...

By not help me in this situation I mean it wont help me as I dont know how to use that to make vanilla blocks drop something. How do I use that in minecraft code?

[L.J.Duckfield]

then think of a block that drops an item and look at its class. (Redstone being one)

you should be able to work out what you need to do from there. if not, read up on some tutorials.

[Thor597]

Oh trust me I've searched for tutorials a looot, There is actually no-one I can find that does this. And when I search up something like this post name on google all I find is people that says its impossible

[L.J.Duckfield]

took me 2 seconds of looking at RedstoneOre to find this...

    /**
     * Returns the ID of the items to drop on destruction.
     */
    public int idDropped(int par1, Random par2Random, int par3)
    {
        return Item.redstone.shiftedIndex;
    }

 

if dropping one of your mods blocks, replace

    {
        return Item.redstone.shiftedIndex;
    }

 

with...

 

    {
        return mod_XXXX.myItem.shiftedIndex;
    }

 

so as i said, its in Redstone ore...as an example

Nope, not without editing base classes.

Did you read the topic name HOW TO ADD ITEM DROPS TO VANILLA BLOCKS WITHOUT EDITING BASE CLASSES LIKE MAKING ICE DROP SOMETHING WITHOUT EDITING BLOCKICE.JAVA

[L.J.Duckfield]

Yes and that was given to you above... Java Reflection.

How do I use java reflection in minecraft code to help me do this then? Please help me D:

[LexManos]

Alright just to shut up people

You cant

I want to add a hook for this but its very low on my priorities list right now.

People who are saying reflection, please stop being a dick and only say reflection when you are right.

[atrain99]

As above, I agree.

Maybe try to do something with a watcher class that checks the world for onBlockRemoval events, and then spawn the entity for salt.

thats a litte code to add EMC values to your own blocks, I guess it may help...
