want to make a fixed rotation speed in Lerp no matter what the angle is
I'm working on a 2d Project and I'm New to rotations and Quaternoin,I want to make a fixed rotation speed in Lerp no matter what the angle is. Here is my code:
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class enemyScript : MonoBehaviour
{
Rigidbody2D rb;
[SerializeField] GameObject Bullet, Player, FireSpot;
[SerializeField] float speed, Duration;
Vector3 Direction;
Quaternion Position;
float time = 0;
float Dot;
void Start()
{
rb = GetComponent<Rigidbody2D>();
Position = transform.rotation;
Dot = Mathf.Acos(Vector3.Dot(Vector3.right, Direction)) * Mathf.Rad2Deg;
}
void FixedUpdate()
{
transform.Translate(-Vector3.right * speed * Time.deltaTime);
if (time > 1)
{
Position = transform.rotation;
Dot = Mathf.Atan2(Direction.y, Direction.x) * Mathf.Rad2Deg;
time = 0;
print(Duration);
}
time += Time.deltaTime * Duration;
Direction = Player.transform.position - transform.position;
Debug.DrawRay(transform.position, Direction, Color.cyan);
Direction.Normalize();
transform.rotation = Quaternion.Lerp(Position, Quaternion.Euler(new Vector3(0, 0, Dot - 180)), time);
}
}
Best Answer
angleDeg = Vector2.Angle(-transform.right,Direction);
time = Time.DeltaTime / (Duration/angleDeg);
hey there,
you basically just have to divide your Time.deltaTime * Duration by the total angle you want to cover. So assuming that Dot is your total angle your calculation each frame is Time.deltaTime * Duration/Dot and it should work as you then have seconds * (angle/second) /angle in your units. Thus leading to no unit which is what you want.
well just realized that Dot is not the delta angle of your rotation. Just calculate that and divide by the total rotation delta instead of Dot
