Hi,
Since a few days i'm trying to create an isometic camera, which rotates exactly 90 degrees when i press Q or E. (counterclock and clockwise). after alot of searching on the forums etc i came up with this code:
void Update()
{
if (Input.GetKeyDown(KeyCode.Q))
{
Ray ray = cam.ViewportPointToRay(new Vector3(0.5f, 0.5f, 0f));
Physics.Raycast(cam.transform.position, cam.transform.forward, out hit);
if (!rotating)
{
rotating = true;
StartCoroutine(rotate(rotateTime, angle, step));
}
}
if (Input.GetKeyDown(KeyCode.E))
{
Ray ray = cam.ViewportPointToRay(new Vector3(0.5f, 0.5f, 0f));
Physics.Raycast(cam.transform.position, cam.transform.forward, out hit);
if (!rotating)
{
rotating = true;
StartCoroutine(rotate(rotateTime, -angle, step));
}
}
}
IEnumerator rotate(float time, float angle, float step)
{
if (rotating)
yield return false;
Vector3 beginAngle = cam.transform.rotation.eulerAngles;
float totalSteps = time / step;
float angleStep = angle / totalSteps;
for (float f = 0f; f <= time; f += step)
{
cam.transform.RotateAround(hit.transform.position, Vector3.up, angleStep);
yield return new WaitForSeconds(step);
}
rotating = false;
}
but there is a small offset at the end, like 1 or 2 degrees, which builds up over time as i rotate more and more. I just want 45, 135, 225 or 315 degrees exact. How should I fix this?
