This might help:
[SerializeField] private float maxChange;
[SerializeField] private float maxVelocity;
private Rigidbody rb;
private Vector3 lastVelocity;
private void Start()
{
rb = GetComponent<Rigidbody>();
lastVelocity = rb.velocity;
}
private void FixedUpdate()
{
// If you want to check velocity change
Vector3 velocity = rb.velocity;
float dif = Mathf.Abs((velocity - lastVelocity).magnitude) / Time.fixedDeltaTime;
if (dif > maxChange)
{
Damage();
}
lastVelocity = velocity;
// If you want to check velocity.
if (rb.velocity.magnitude > maxVelocity)
{
Damage();
}
}
private void Damage()
{
// Do some damage.
}
For example, if you are falling, your velocity will increase by 9.81, but your velocity change will always be 9.81, so choose what you want.
