I've been wondering for a while. Would it be possible to make a block to detect if a block touching it is broken or set to air. Because I currently have a block that breaks nearby blocks of it's name, but I would like to try to make it cause all blocks of itself that it is touching... I can assume it has to do with NeighborBlockchange, or similar method, but not sure how to do it. I will say, sugarcane and cactus could be a similar comparison, except it needs to not drop items, except for the one destroyed by player.

hmm, so guessing it's not possible to make a block (when destroyed by player) to break all blocks of itself. Like if you lay a block in an indefinite line and break one of them anywhere in said line it would result in the whole line breaking, and giving the drop at the one broken only?

Hmm... So going to assume I should use a for loop to simplify the checking of blocks on each side and make each block set themselves to air? But wouldn't this make the blocks break if any neighbor change, like if you break a stone that is next to said block? Also it seems that when I use a code similar to this:

 

    	 for (int i = x-1; i <= x+1; ++i) {
    		 for (int k = y-1; k <= y+1; ++k) {
    			 for (int j = z-1; j <= z+1; ++j) {
        		     if(world.getBlock(i, k, j) == this) 
        	    	    {
        	    	    	world.setBlockToAir(i, k, j);
        	    	    }
    			 }
    		 }
    	 }

 

I don't seem to be able to make a block break in a 3x3x3 cube. What's wrong with it?

 

 

edit--

Ok I have tried to make it check the blocks around it I think, but now it makes it so when I place any block near one of mine it makes the ones it directly touches to disappear. This is the code:

 

public void onNeighborBlockChange(World world, int x, int y, int z, Block block)
{
	if(block != this){
		world.setBlockToAir(x, y, z);
	}
}

 

 

OK great news, I finally got the code to work, so simple I passed it over, all I had to do was add a Boolean that is set to false at the start of the class, then make it get set to true in the onBlockDestroyedByPlayer method, and then have the Boolean as one of the attributes of the if statement within the onNeighborBlockChange method. Really shrunk my old code. Who needs it to break in a 3x3x3 cube.
