How can I access OnVelocityChange Event?
The OnVelocityChange
event is a part of the Unity game engine's physics system, specifically the Rigidbody
component. It is called whenever the velocity of a Rigidbody
changes.
To access the OnVelocityChange
event in Unity, you can follow these steps:
Select the game object that has the
Rigidbody
component you want to work with in the Unity editor.In the inspector window, scroll down to the
Rigidbody
component and expand it.Look for the
Interpolate
setting and set it toInterpolate.FixedUpdate
. This is important becauseOnVelocityChange
is called during the fixed update step.In your script, you can add the
OnVelocityChange
event by creating a method with the following signature:arduinovoid OnVelocityChange(Vector3 newVelocity);
Note that the method must be public and belong to a class that extends
MonoBehaviour
. You can then attach the script to the game object that has theRigidbody
component.Whenever the velocity of the
Rigidbody
changes, theOnVelocityChange
event will be called with the new velocity as the parameter.
Here is an example script that demonstrates how to use the OnVelocityChange
event:
csharpusing UnityEngine;
public class VelocityChangeHandler : MonoBehaviour
{
public void OnVelocityChange(Vector3 newVelocity)
{
Debug.Log($"Velocity changed to {newVelocity}");
}
}
Attach this script to a game object that has a Rigidbody
component with Interpolate
set to Interpolate.FixedUpdate
, and the OnVelocityChange
method will be called whenever the velocity of the Rigidbody
changes.
