Ranged item new option - Is bullet affected by gravity?

Hello, I was thinking about creating a new option for ranged item:

Is bullet affected by gravity?

What will change in the bullet code:

public static ArrowCustomEntity shoot(LivingEntity entity, LivingEntity target) {

...

        entityarrow.setSilent(true);
        entityarrow.setDamage(5);
        entityarrow.setKnockbackStrength(5);

       entityarrow.setNoGravity(true/false);

       entityarrow.setIsCritical(false);
        entity.world.addEntity(entityarrow);
