How to calculate speed & distance on a sphere?
Hello,
So I am doing this game where the characters runs forever on a sphere Object. I want to calculate how manny feets & miles he travels. I found out that 1 foot equals 0.17 degrees on the eurlangles.x of the sphere.
I tried :
float rota = transform.eulerAngles.x;
Debug.Log(rota);
if(rota % 0.17<=0.1f)
{
feet++;
}
It kind of works, the problem is that it's on Update and it's doing it when it's not supposed to, or too often.
I am looking for a way to count 1 feet each time the sphere turns 0.17 degrees.
Any ideas?
The problem probably occurs because you calculate distance based on rotation and not the actual distance traveled by sphere. What if sphere jumps for a frame or two? It would mess numbers. I'd use this
private float Dist=0f;
private Vector3 PrevPosition;
void Start(){
StartPosition=transform.Position;
}
void Update(){
Dist+=Vector3.Distance(transform.Position,PrevPosition);
PrevPosition=transform.Position
}
Now this way you would have exact amount of distance travelled by your sphere. Another idea to make it your way is to use FixedUpdate or LateUpdate instead of Update.
