How to Limit Speed of a Rigidbody?

Questions & Answers
1

Hey everybody,

Can somebody help out with this bit of code? I’m not sure why it doesn’t work.

I am trying to limit the speed of the rigidbody to 10.

	// Trying to Limit Speed
	if(rigidbody.velocity.magnitude > 10){
    	rigidbody.velocity = Vector3.ClampMagnitude(rigidbody.velocity, maxSpeed);
    	print("Why Doesn't this Work?");
        }

Why Doesn’t this Work? is showing up in the Console, but my speed is not being limited.

Any help is really appreciated.

Thanks!

Drag this on the cube:

using UnityEngine;
using System.Collections;

[RequireComponent (typeof (Rigidbody))]
public class NewBehaviourScript : MonoBehaviour {
	public float maxSpeed = 10f;

	void Update()
	{
		// Trying to Limit Speed
		if(rigidbody.velocity.magnitude > maxSpeed){
			rigidbody.velocity = Vector3.ClampMagnitude(rigidbody.velocity, maxSpeed);
		}
	}

	void OnGUI()
	{
		GUI.Label(new Rect(20, 20, 200, 200), "rigidbody velocity: " + rigidbody.velocity);
	}
    }

diff.Normalize();
rb2d.AddForce(diff * Aceleracion * Time.fixedDeltaTime);
float speed = Vector3.Magnitude(rb2d.velocity); // test current object speed
if (speed > VelocidadMaxima)

        {
            float brakeSpeed = speed - VelocidadMaxima;  // calculate the speed decrease

            Vector3 normalisedVelocity = rb2d.velocity.normalized;
            Vector3 brakeVelocity = normalisedVelocity * brakeSpeed;  // make the brake Vector3 value

            rb2d.AddForce(-brakeVelocity);  // apply opposing brake force
        }
