            player.playSound(SoundEvents.FLINTANDSTEEL_USE, 1.0f, random.nextFloat() * 0.4f + 0.8f);
            int fireTick = random.nextInt(10 * 20 + 1) + 20;
            if (fireTick > target.getRemainingFireTicks()) {
                target.setSecondsOnFire(fireTick);
            }

            return ActionResultType.CONSUME;
        }
        return ActionResultType.FAIL;
    }
}

It has three actions

1. use on block -> act like flint and steel (useOn in FlintAndSteelItem.class)

2. use on entity -> light entity on fire (interactLivingEntity)

3. use on air -> light player on fire (use)

 

When I use it on entity (case 2), it light both entity and player on fire.

But I want to make it light only entity on fire.

Give me help please.

That is strange, I can't see why it would do that. I would recommend using the debugger.

I solved this problem by using

return ActionResultType.CONSUME;

in interactLivingEntity instead of using super.interactLivingEntity()
