Getting fall height of player

How can i check height of player fall? I mean I know that i can check damage of event and compare it with this what i want (if fall from 3 blocks then do smt, if fall from <4 then do smth else) BUT
this will not work if player wears some equipment like chest or helmet, can you help me wiith this?

 

Not tested though it should work:

Code:

    public static int getFallHeight(Player p){
        int y1 = (int) p.getLocation().getY();
        int y2 = 0;
        Block b = p.getLocation().getBlock();
        while(!(b = b.getRelative(BlockFace.DOWN)).getType().isSolid())
            y2 = b.getY();
        return y1-y2;
    }

Note that this is before they actually hit ground and it is essentially an estimate. And after reading your post again I realise this isn't what you're looking for, sorry.

Did a few tests with various armor types (and featherfalling enchant) and found that the raw damage is always posted for the fall damage even if the player actually takes less damage. An estimate on how far they fell is falldamage+3. Hopefully that should help a little.

Works only if player take any damage

Code:java

 if (event.getCause().equals(EntityDamageEvent.DamageCause.FALL)) {
float fDist = eventEntity.getFallDistance();
//do something
 }
