make block change on right click?(with a certain item in player hand)[solved]

Posted March 3, 201312 yr

how would one go about making a block change on rightclick? I mean the proper way, i know some ways to do it (using worldgen to place the new block at the same location as the old block) but what method & parameter would i use to check the item in a payers hand?

Also, I should have you know that you are reading my signature.

EDIT:

i have found a way to get the item in hand, would the worldplacing method still work?

 
   public void onBlockClicked(World par1World, int par2, int par3, int par4, EntityPlayer p5EP) {
    	if(p5EP.inventory.currentItem == 0){
    		//changeblock here
    	}
    }

you could either check from the block the player is right clicking on or you could use the following from your Item override class

public boolean onItemUse(ItemStack tool,
		EntityPlayer player, World world, int x, int y,
		int z, int par7, float xFloat, float yFloat, float zFloat)
{

	if (!player.canPlayerEdit(x, y, z, par7, tool))//can the player edit this block? if he cant then dont do anything
	{
		return false;
	}
world.setBlockAndMetadataWithNotify(x, y, z, 0, Block.blockDiamond.blockID); // sets the block to diamond block with the meta data 0 (used for setting metadata if the block needs it
	world.setBlockWithNotify(x, y, z, Block.blockDiamond.blockID); // sets the block to diamond block with no meta data
}

which would waste less CPU cycles?

the corect way would be

private Block toBlock = new BlockNewBlockHere()
public void onBlockActivated(World par1World, int par2, int par3, int par4, EntityPlayer player) {
     if(player.inventory.currentItem == 0){
      par1World.setBlockId(par2,par3,par4,toBlock.blockID);
     }
    }

there is no setBlockID method.

Also, I should have you know that you are reading my signature.

anyone? i'm honestly lost here.

Also, I should have you know that you are reading my signature.

March 8, 201312 yr

just going on a hunch here, but have you tried using null checks (given that your error is caused by a null value) is just add a few bits like

if(player != null){

or

if(player.inventory.getCurrentItem() != null){

again this is just a hunch as i don't know what is on line 27 of TGrayCobble, where it seems throwing a null pointer exception

how do you get it to change its texture on an item rightclick?

I'm fairly sure that if you're not holding anything, getCurrentItem() returns null. I could be wrong. It could return 0. Don't quote me on that.

you can do it two ways... one is to just on block activated then check the players current item and the other(more laggy unless is meant for more than 1 use) is to have a on right clicked in the item

is my error considered a bug? because i honestly have no clue here, i get the same error if i try to place the block above it (which is air).

If the player's hand is empty the ItemStack is null, not item ID 0. You can either null check or try/catch.

    public void onBlockClicked(World par1World, int par2, int par3, int par4, EntityPlayer p5EP) {
     if( p5ep != null && && p5EP.inventory.getCurrentItem().itemID != null){
      if(p5EP.inventory.getCurrentItem().itemID == 1 && par2 * par3 != 0 && par2 * par4 != 0){
       par1World.setBlock(par2, par3, par4, 4);
      }
     }
     System.out.println("debug tick.");
    }

Thought I should add:

When null checking, go from least specific to most specific.

For example:

if(Object1.method1() != null && Object1 != null){
System.out.println(Object1.method1().toString());
}

This will cause a null pointer exception if Object1 is null because it is trying to call a method (method1) from a null object. However, if you did this:

if(Object1 != null && Object1.method1() != null){
System.out.println(Object1.method1().toString());
}

This will not cause a null pointer exception because it will break out of the if statement before it tries to call a method from a null object.
