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?

getCurrentEquippedItem will be null if the hand is empty.

Ok, fixed it now by adding

player.getCurrentEquippedItem() == null ||
