How to set rotation.y to predefined angles.
Here the character moves towards the point where you click, it successfully does that, but the problem is i want the character's rotation only to be setup in 0,90,180 and 270 degrees only,so i am trying to setup its value but the player is still uses default rotation.y that is any degree(26.333 for eg).
void MoveDir(Vector3 position)
{
Vector3 dir = position - transform.position;
Quaternion rotation = Quaternion.LookRotation(dir);
rotation.x = 0;
rotation.z = 0;
rotationcheck = rotation.y;
if(rotationcheck>45.0f && rotationcheck<=135.0f)
{
rotation.y = 90f;
}
else if(rotationcheck>135.0f && rotationcheck<=225.0f)
{
rotation.y = 180f;
}
else if(rotationcheck>225.0f && rotationcheck<=315.0f)
{
rotation.y = 270f;
}
else if(rotationcheck>315.0f && rotationcheck<=45.0f)
{
rotation.y = 0f;
}
players.transform.rotation = rotation;
}
Sorry... I gained help from thePersitor below... Here is what worked for me:
float shipHeading = 0f - pShipHullF.gameObject.transform.rotation.eulerAngles.y;
spinDial.rotation = Quaternion.Euler(new Vector3(0f, 0f, shipHeading));
I'm taking the y rotation of my ship and applying that rotation to a dial on a UI image, which rotates on the z. $$anonymous$$aybe this will help someone.
First, you need to understand that transform.rotation is a Quaternion in which x,y,z are not angles. Please read this answer:

As for your question, you can do it this way:
Vector3 dir = position - transform.position;
float angle = Mathf.Atan2(dir.x, dir.z) * Mathf.Rad2Deg;
angle = Mathf.Round (angle / 90.0f) * 90.0f;
transform.rotation = Quaternion.AngleAxis (angle, Vector3.up);
Quaternions contain values between 0 and 1, therefore, if you set 90, 180, 270 or 0 in them directly, it'll go all drunk on you.
Instead, use EulerAngles for setting absolute values:
// Store Transform as a variable instead of calling the hidden GetComponent :)
Transform m_Transform;
void Start()
{
// Fill m_Transform
m_Transform = transform;
}
private void SnappedLookAt(Vector3 targetPos)
{
// Simple LookAt usage, remove unwanted axici if wished for
m_Transform.LookAt(targetPos);
// Easy way to snap to a value, divide it so you get a number between 0 and 4,
// round that, then multiply by 90 resulting in 0, 90, 180, 270 or 360. :)
float snappedValue = Mathf.RoundToInt(m_Transform.rotation.eulerAngles.y / 90) * 90;
// Now set the rotation (x and z unchanged, y snapped)
m_Transform.rotation = Quaternion.Euler(
new Vector3(
m_Transform.rotation.eulerAngles.x,
snappedValue,
m_Transform.rotation.eulerAngles.z));
}
That should do the trick. I hope that helps, if you have anymore questions, feel free to ask, if this answer was satisfying enough, please accept it and move onwards with your epic game programming journeys! :D
