If I took a block and set a onBlockActivated method and check the tool that click the block and drop the block could I do that so that block requires a special tool

Because I have almost no idea what you want to archieve I'll just ask:

1. "If I took a block"

Vanilla or custom?

2. "onBlockActivated method"

Should it be block activation, break or right-click?

3. "check the tool that click the block"

Again - which click? Left, right? Only click or break?

4 "drop the block"

Well, dropping need breaking, so are you activating block, breaking it or clicking?

5. "block requires a special tool"

How can block "require" special tool? Then again - speacial tool to break it, or to activate it?

 

Last, but not least - are you high?

You are probably looking for BlockBreakEvent or PlayerInteractEvent (or something like it) for Vanilla, and for custom, probably: on BlockDestroyedByPlayer maybe. Anyway - events mentioned 1st can be cancelled to no break block, or you can modify their loot to loot other stuff depending on tool used.

1. take custom block

2. use the onBlockActivated method to check if it was shift+right clicked

3. check what item was used

4. if the item was lets say a "wrench" then replace block with air then spawn the item

Maybe something like

 

	public void onBlockActivated(World par1World, int par2, int par3, int par4, EntityPlayer player) {
	if(!par1World.isRemote)
	{
		if(player.inventory.getCurrentItem().getItem() == Items.wrench && player.isSneaking()){
			     //stuff
	    }
	}
}

In theory that should work right?

Idk why you are trying to simulate breaking block by using onBlockActivated, but that's not my concern.

 

Yeah, in theory (even practice) that should work. Remember to always check if slot in not null before you try to get item from it.

Also use instanceof instead of "==". (Unless you want a direct to-class comprasion).

 

Finally - to break block you can setBlock to air (depending on which version you use 1.7 or 1.8 methods are different) or simulate BlockBreak by simply telling block to insta-break.

 

In any case - to drop items you should use: BlockFurnace#breakBlock(), code starting with EntityItem entityitem = new EntityItem....

Idk why you are trying to simulate breaking block by using onBlockActivated, but that's not my concern.

 

It comes from IC2: just "mining" the block out ruins the machine.  You have to use a wrench and "disassemble it" (shift-right click, as right-click just rotates it).
