[1.7.2] [UNSOLVED]how to use Events

[MrNegaBlox]

How do I find all the packages holding the code for minecraft, I used to be able to read it to figure out. Thank you in advance.[sOLVED]

 

Also, how do I get have a block do something when it is placed and/or broken? what is the method in doing so?

[Jacky2611]

the minecraft src is in "Referenced Libraries/forgeSrc"

 

Break/placed(from Block.class):

    /**
     * Called right before the block is destroyed by a player.  Args: world, x, y, z, metaData
     */
    public void onBlockDestroyedByPlayer(World p_149664_1_, int p_149664_2_, int p_149664_3_, int p_149664_4_, int p_149664_5_) {}

    /**
     * Called whenever the block is added into the world. Args: world, x, y, z
     */
    public void onBlockAdded(World p_149726_1_, int p_149726_2_, int p_149726_3_, int p_149726_4_) {}

 

don't forget the thank you button.

I did those methods doing this.

@SubscribeEvent
public void onBlockAdded(World p_149726_1_, int p_149726_2_, int p_149726_3_, int p_149726_4_) {
	p_149726_1_.setBlockToAir(p_149726_2_ - 1, p_149726_3_ - 1, p_149726_4_ - 1);

}

But nothing happened when I placed a block.

If those were events, you would also have to register your class with the correct event handler.

 

But they are not events, so you merely need to

@Override

the methods in your Block descendant.

 

Enjoy

I think I might know what the problem is. I set up a base block that use a subclass of the original block. and the block where I placed the method was a subclass of that, so I don't know if that really affects anything, but it isn't working. so I don't know

[Elyon]

That will still work.

 

Did you use

@Override

instead of

@SubscribeEvent

?

 

If you're still having issues, showing your code and any errors you get is a good start

Found them in the Block.class in 10 second:

 

public void onBlockDestroyedByPlayer(World p_149664_1_, int p_149664_2_, int p_149664_3_, int p_149664_4_, int p_149664_5_){}

 

public int onBlockPlaced(World p_149660_1_, int p_149660_2_, int p_149660_3_, int p_149660_4_, int p_149660_5_, float p_149660_6_, float p_149660_7_, float p_149660_8_, int p_149660_9_) {}

oh, I was being so stupid... I forgot in my blocks folder to make my block the instance of my new class instead of my base one. im sorry for all the trouble but thank you all!
