How to draw an elliptical circle path for animated object?
Hi guys, I am new to unity3d world . I want to draw an elliptical circle path for my moving object My question how can I do this is there any way to generate the elliptical circle from mathematics equations and algorithms or should I create this path by 3dsmax. if you have any suggestion or any related tutorial please help
Do you want a visible path? Or do you just want an object to travel along an elliptical path?
I've asked a similar question: How to make computer controlled cars? I want the road to be visible(of course), but the path'd be hidden.
The'll be moving in a more complicated way though, but the answer should be similar, so pls reply to my answer too.
You can use trigonometry to calculate the position of the object in the elliptical path, this way:
using UnityEngine;
using System.Collections;
public class EllipticalPathCS : MonoBehaviour {
public Vector3 center = new Vector3(0, 1, 0);
public float radiusA = 5;
public float radiusB = 10;
public float speed = 1;
private float angle;
// Use this for initialization
void Start () {
}
// Update is called once per frame
void Update () {
angle += speed * Time.deltaTime;
// Calculates position with parametric form, explanation:
// http://en.wikipedia.org/wiki/Ellipse#Parametric_form_in_canonical_position
float x = radiusA * Mathf.Cos(angle);
float y = radiusB * Mathf.Sin(angle);
transform.position = center + new Vector3(x, 0, y);
}
}
