Like can i change the behavior of something that exists in minecraft to do something else?

 

specifically i want something like

 

//pseudo code for example

Class Glowstonedust{
	onclickonground{
		place(Glowstonewire);
	}
}

There's an event for that: PlayerInteractEvent#RightClickBlock.

so like if i am rightclicking on an item in say slot#2 and i want it to place a block i would use PlayerInteractEvent#RightClickBlock

If you are using a vanilla item yes. If you are creating your own item override onItemUse or just make it a BlockItem.

I would look into how redstone does it. Pretty sure you'll need to create a new TileEntity to do this.

No.

Redstone's item overrides a method that Glowstone dust's item does not. This only way to get the required behaviour is to use an event, as ChampionAsh already said.

Absolutely not. Redstone dust wire does not use a tile entity.

there is not any class of the Item it is just a normal BlockNamedItem

see:

net.minecraft.item.Items

Note that BlockNamedItem is a subclass of Item that overrides methods and that glowstone dust is just a regular Item.

So my statement is no less false.

Okay well i got the other Stuff to work. But how do i place the block. is their a method for that?

You have created the block, yes? Placing the block depends on how you're doing it, whether you're overriding the vanilla class just to add this functionality or if you're using the PlayerInteractEvent#RightClickBlock. Supposing you're using the latter, you check what you want, such as player is holding this item, and then getWorld() for placing the block, getPos() for the block the player is looking at, and getSide() to increment the direction so you don't just replace the block, and use World#setBlockState to place the block. Make sure to check that the block you're replacing is replaceable.
