Limit Speed One Axis

Archived Forums Questions & Answers

Hello,
I was wondering how to limit speed on one axis for an object. I have a script that limits speed for my game object but when the object falls it is also limited.

How can I limit the speed of just one axis?
Thanks

What does your existing script do? It shouldn't be very hard to hack that to only affect one axis!

Well you could try reducing the amount your velocity is being affected. I think i would try

if(Mathf.Abs(rigidbody.velocity.y) > maxspeed) (rigidbody.velocity.y = rigidbody.velocity.y - 3) 

if(Mathf.Abs(rigidbody.velocity.y) < -maxspeed) (rigidbody.velocity.y = rigidbody.velocity.y + 3) 
Find the magic number that arrests acceleration and your good to go.

Have you tried to exchange "-3" and "+3" in @chemicalvamp's script? This is just a suggestion, but maybe you are using an "inverse" coordinate system that doesn't match exactly with that script.

[UPDATE]: or maybe "maxspeed" with "-maxspeed": now that I think better about it, it would have much sense. Not sure about that yet, however, it's just a try...

Checked and double checked this is working for me, and I took out what was unnecessary

using UnityEngine;

public class SlowFall : MonoBehaviour

{

public float maxspeed = 1;
public float speedreduction = 1;

void Update()
{
    Vector3 Adjustment = Vector3.zero;
    if (transform.rigidbody.velocity.y > maxspeed)
    {
        Adjustment.y += -speedreduction;
    }
    if (transform.rigidbody.velocity.y < -maxspeed)
    {
        Adjustment.y += speedreduction;
    }
    rigidbody.velocity += Adjustment;
}

}
