Quaternion RotateTowards issues
Trying to rotate the directional light. I'm pretty sure I've set it up the same as the documentation at https://docs.unity3d.com/ScriptReference/Quaternion.RotateTowards.html but obviously I'm understanding something wrong. Here's the code:
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class MoveSun : MonoBehaviour {
public GameObject scripts; //drag the gameObject that contains the clock script into here
public GameObject sun; //drag the directional light into here
private int currentTime;
private int sunriseTime = 28800;
private int sunsetTime = 57600;
private double sunSpeed = 1.0 / 240.0;
private float noonAngle = 13f;
private float noonTime;
private Quaternion sunrise = Quaternion.Euler(0, 0, 0);
private Quaternion noon;
private Quaternion sunset = Quaternion.Euler(0, 180, 0);
void Start () {
currentTime = scripts.GetComponent<Clock>().secCount;
noon = Quaternion.Euler(noonAngle, 90, 0);
noonTime = (sunsetTime + sunriseTime) / 2;
Debug.Log(noonTime);
}
void Update () {
currentTime = scripts.GetComponent<Clock>().secCount;
var step = sunSpeed * currentTime;
if (currentTime >= sunriseTime && currentTime < noonTime)
{
sun.transform.rotation = Quaternion.RotateTowards(sunrise, noon, (float)step);
Debug.Log("Sun is rising!");
}
else if (currentTime >= noonTime && currentTime < sunsetTime)
{
sun.transform.rotation = Quaternion.RotateTowards(noon, sunset, (float)step);
Debug.Log("Sun is setting!");
}
}
}
The secCount is simply timeSpeed*Time.deltaTime in another script. The if statements are running but the sun goes to sunset at doesn't move (the game time starts at 12pm). Or if I start before 12pm the sun jumps to noon and doesn't move.
I think the issues are in my conditions somewhere. Just tried to use a while loop and broke Unity :(
test changing the quaternion lines to this
sun.transform.rotation = Quaternion.RotateTowards( sun.transform.rotation, noon, (float)step);
unless i am missing something usnrise value is not being updated so every frame you are rotating from 0,0,0 to 0,0,180 so is always the same value.
Tried that and it still jumps :(
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class $$anonymous$$oveSun : $$anonymous$$onoBehaviour
{
public GameObject scripts; //drag the gameObject that contains the clock script into here
public GameObject sun; //drag the directional light into here
private int currentTime;
private int sunriseTime = 28800;
private int sunsetTime = 57600;
private float sunSpeed = 1.0f / 240.0f;
private float timeSpeed;
private float noonAngle = 13f;
private float noonTime;
private Quaternion sunrise = Quaternion.Euler(0, 0, 0);
private Quaternion noon;
private Quaternion sunset = Quaternion.Euler(0, 180, 0);
void Start()
{
currentTime = scripts.GetComponent<Clock>().secCount;
timeSpeed = scripts.GetComponent<Clock>().timeSpeed;
noon = Quaternion.Euler(noonAngle, 90, 0);
noonTime = (sunsetTime + sunriseTime) / 2;
}
void Update()
{
currentTime = scripts.GetComponent<Clock>().secCount;
timeSpeed = scripts.GetComponent<Clock>().timeSpeed;
sunSpeed = (1.0f / 240.0f) * timeSpeed;
var step = sunSpeed * currentTime;
if (currentTime >= sunriseTime && currentTime < noonTime)
{
sun.transform.rotation = Quaternion.RotateTowards(sun.transform.rotation, noon, step);
Debug.Log("Sun is rising!");
}
else if (currentTime >= noonTime && currentTime < sunsetTime)
{
sun.transform.rotation = Quaternion.RotateTowards(sun.transform.rotation, sunset, step);
Debug.Log("Sun is setting!");
}
}
}
by jump you mean it reaches the noon/sunset rotation and doesnt move rotate again?
Yes, sorry if that wasn't clear. I hit the specified sunriseTime and the sun instantly moves to noon. Or if later, the clock hits the specified noon time and the sun instantly jumps to sunset position.
