Don´t get a DamageAnimation when FallDamage

I have a problem with my DamageListener I want to remove the DamageAnimation when someone gets falldamage., but sometimes it works and sometimes it doesn´t. Does anyone have an idea why?

Code:

public void onDamage(EntityDamageEvent e) {
        Player p = (Player) e.getEntity();
        if(e.getCause().equals(DamageCause.FALL)) {
            double damage = e.getDamage();
            e.setCancelled(true);
            p.playSound(p.getLocation(), Sound.FALL_SMALL, 10, 1);
            if(p.getHealth() <= damage) {
                p.setHealth(0.0D);
            }else {
                p.setHealth(p.getHealth()-damage);
            }
           
        }
    }

 

Can you define by sometimes it works and sometimes it doesn't?

 

if(p.getHealth() <= damage) {
p.setHealth(0.0D);
}
If the player is full and takes 10 damage, and the players health is now at 10, wouldn't p.getHealt() = damage?
Just a thought.

 

He checks for that before he applies the damage so that shouldn't cause any problems
