[1.7.10] [SOLVED] TileEntity isUseableByPlayer

[Bektor]

Hello,

 

I've created with Forge 1.7.10-10.13.1.1224 a custom "furnace", but now I have one problem:

 

Everytime if I'm right clicking on it, the Game is crashing:

So the "furnace" should only be burning if there is wood in it and if you did a right click with an flient and steel.

 

The block code:

 

@Override
    public void onBlockClicked(World world, int x, int y, int z, EntityPlayer player) 
{
	if(world.isRemote)
		return;

	if(!player.isSneaking())
	{
		if(player.getCurrentEquippedItem().getItem() == Items.flint_and_steel)
		{
			if(!world.isRaining() && !world.isThundering() && !world.canBlockSeeTheSky(x, y, z))
				setBurning(true);
			else
				setBurning(false);
		}
		else
			setBurning(false);
	}
	else
		setBurning(false);
}

 

 

The TileEntity-Code:

 

@Override
public boolean isUseableByPlayer(EntityPlayer player) 
{
	return this.worldObj.getTileEntity(this.xCoord, this.yCoord, this.zCoord) != this ? false : (player.getDistanceSq((double) this.xCoord + 0.5D, (double) this.yCoord + 0.5D, (double) this.zCoord + 0.5D) <= 14.0D && player.getCurrentEquippedItem().getItem() != Items.flint_and_steel);
}

 

 

I hope someone can help me to fix this problem...

The line of code that makes problems is the only line in the isUseableByPlayer method that I posted a few lines over this here.

Is it so hard to run in debug mode and see what variable is null?

[Bektor]

getCurrentEquippedItem will be null if the hand is empty.

Ok, fixed it now by adding

player.getCurrentEquippedItem() == null ||
