Problem with 3d jump

[Snoopy137]

Hello community

I'm trying to make a player jump but the animation is having a problem, when falling instead of constanly goind down, when it reach certain point it goes instantly to the ground height. I use a player component to create the jump and implement the logic by overwriting the onUpdate method
I am not using physics world becaus jbox cannot be applied to 3d objects

I use the following code

`@Override

public void onUpdate(double tpf) {

    if (playerHeigh.compareTo(getEntity().getY()) == -1) {

        getEntity().translateY(-.005);

    }

    if (playerHeigh.compareTo(getEntity().getY()) == 1) {

        getEntity().translateY(.005);

    }

    System.out.println("player Height " + playerHeigh + " player actual y " + getEntity().getY());

}`

the player goes up well but the falling fails, I used the print function to see how is the workflo and got the following

`player Height 4.8 ---------- player actual y 4.6750000000000025

player Height 4.8 ---------- player actual y 4.680000000000002

player Height 4.8 ---------- player actual y 4.685000000000002

player Height 4.8 ---------- player actual y 4.690000000000002

player Height 4.8 ---------- player actual y 4.695000000000002

player Height 4.8 ---------- player actual y 4.700000000000002

player Height 4.8 ---------- player actual y 4.8`

So basically when it reaches the 4.700 height it goes down to 4.8 instead of translateY by 0.005 as the method states.
Does any one know what could I do to fix this?
Thanks in advance!

Please disregard this, my collision handlers was wrong

The logic was wrong
