[SOLVED]How can I abort the player's left-click action?

I've noticed that in some weapon-related mods such as iChun's portal gun, player can use both left key and right key to shoot.

I found this really good, so I started trying doing something similar. Having tried custom KeyCode and simple processing, all them works well. However I can't manage to find the related function to abort player's clicking action on left click.

I've tried all the codes below :

    public boolean onLeftClickEntity(ItemStack stack, EntityPlayer player, Entity entity)
    {
    	return true;
    }
    
    public boolean onEntitySwing(EntityLiving entityLiving, ItemStack stack)
    {
    	return true;
    }
    
    public EnumAction getItemUseAction(ItemStack par1ItemStack)
    {
    	return EnumAction.none;
    }
    
    public boolean onBlockStartBreak(ItemStack itemstack, int i, int j, int k, EntityPlayer player)
    {
      return true;
    }
    
    public boolean onItemUseFirst(ItemStack stack, EntityPlayer player, World world, int x, int y, int z, int side, float hitX, float hitY, float hitZ)
    {
      return true;
    }

 

Also tried this in EventHandler :

  @ForgeSubscribe
  public void onInteract(EntityInteractEvent event)
  {
	  ItemStack curItem = event.entityPlayer.getCurrentEquippedItem();
	  if(curItem != null && curItem.getItem() instanceof MyItem) {
                            event.setCanceled(true);
	  }
  }

But the result isn't what I expected. Though left clicking won't attack mobs or break blocks anymore, The player's right hand always keep that 'swinging' animation when I click the left mouse button.

What should I do if I want to abort the left-clicking action? Is there something I should do with EntityPlayer class or custom render?

Thanks a lot for your time reading and answering  ;)

This,placed in your item, prevents the swing animation from both clicks. That should do, combined with your cancelled event.

public boolean onEntitySwing(EntityLivingBase entityLiving, ItemStack stack)
    {
/*you can add your custom item use action for both clicks here*/
    	return true;
    }

 

    public EnumAction getItemUseAction(ItemStack par1ItemStack)
    {
    	return EnumAction.none;
    }

This prevents any animation on right click. (it is already in Item by default by the way)

Aha, I think I've figured this out.

I tried System.out.println() in onEntitySwing(), however nothing appeared on the console in any situation.

I belive that this function is not called in update codes by mistake (Or for some special reason?)

in EntityLiving, there's a boolean named isSwingInProgress, so I tried the code below :

@Override
public void onUpdate(ItemStack par1ItemStack, World par2World,
		Entity par3Entity, int par4, boolean par5) {
	super.onUpdate(par1ItemStack, par2World, par3Entity, par4,par5);
	if(par5 && par3Entity instanceof EntityLiving) { //par5:isCurrentHeldItem
		((EntityLiving)par3Entity).isSwingInProgress = false;
	}
}

EDIT: Tested in forge 1.5.2.

Then all of the function works well. Binding with canceling event and abort interacting, this is the effect that I exactly want :D

That function is called if you use the right arguments. See my code for a working example.
