Hi all, I am trying to make a targeting system with an artillery turret in which there is a set distance, velocity, and gravity acceleration. This targeting system is supposed to calculate the angle in which the turret should fire at to hit the target. I am having some trouble as it is either undershooting or overshooting the target, and am wondering if I have the ratios of real world values like Unity velocity to Real World velocity mixed up or if the equation is wrong. Here is my code:
- public class test : MonoBehaviour {
- public float angle;
- public float g = Physics.gravity.y;
- public float v = 1f;
- public float d;
- public Transform firePoint;
- public Transform target;
- public TestAAT3 obj;
- // Use this for initialization
- void Start () {
- obj = FindObjectOfType();
- }
- // Update is called once per frame
- void Update () {
- if (Input.GetKeyDown(KeyCode.Alpha1))
- {
- CalculateAngle();
- }
- }
- //d = distance between firepoint and target
- //g = gravitational acceleration
- //v = given velocity
- //angle = theta
- public void CalculateAngle()
- {
- d = Vector3.Distance(firePoint.position, target.position);
- angle = (1/2) * Mathf.Asin((g * d) / (Mathf.Pow(v_, 2)));
- Debug.Log(d);
- obj.Fire(d);
- }
- }
Any and ALL help is appreciated. I’ve looked at wikipedia, khan academy videos, etc. Nothing helps!
