Camera rotation over Player
Hi, Im very new to Gamedevelopment and currently Im doing my first Steps with Unity, but Im already facing a problem I can't solve with my small knowledge and hope someone could help me a bit.
I have a GameObject which should be my Player and the normal MainCamera in a scene.
I want to let the camera follow my player in a way that I can move the player with the keyboard and look around the player with my mouse inputs. I already have a script thats working, but there is one issue I don't understand. If I try to rotate above my player it works if I look straight forward, but if I rotate the player and try it again, the camera rotates beneath the player instead of rotating over it...
Im using this code:
Everything is working fine, only increaseCameraAngle is making problems, if I have rotated the player with updateCameraRotation before... If I didnt rotate first, the increase works fine... but after a rotation it increases to the left :-(
PlayerController
void Update () {
listenUserInputs ();
}
private void listenUserInputs () {
float keyboardVertical = Input.GetAxis ("Vertical") * movementSpeed * Time.deltaTime;
float keyboardHorizontal = Input.GetAxis ("Horizontal") * movementSpeed * Time.deltaTime;
transform.Translate (keyboardHorizontal, 0, keyboardVertical);
mainCamController.updateHumanPosition (transform);
if (Input.GetMouseButton (0)) {
float mouseVertical = Input.GetAxis("Mouse X") * turningSpeed * Time.deltaTime;
transform.Rotate(0, mouseVertical, 0);
mainCamController.updateCameraRotation(mouseVertical);
}
if (Input.GetAxis("Mouse ScrollWheel") < 0) {
float mouseHorizontal = Input.GetAxis("Mouse ScrollWheel") * turningSpeed * 3 * Time.deltaTime;
mainCamController.decreaseCameraAngle(mouseHorizontal);
}
if (Input.GetAxis("Mouse ScrollWheel") > 0) {
float mouseHorizontal = Input.GetAxis("Mouse ScrollWheel") * turningSpeed * 3 * Time.deltaTime;
mainCamController.increaseCameraAngle(mouseHorizontal);
}
}
CameraController
void Update () {
if (humanPosition != null) {
transform.position = humanPosition.position + humanOffset;
transform.LookAt (humanPosition.position);
}
}
public void updateHumanPosition (Transform newPosition) {
this.humanPosition = newPosition;
}
public void updateCameraRotation (float newValue) {
humanOffset = Quaternion.AngleAxis (newValue, Vector3.up) * humanOffset;
}
public void increaseCameraAngle (float newValue) {
humanOffset = Quaternion.AngleAxis (newValue, Vector3.right) * humanOffset;
}
public void decreaseCameraAngle (float newValue) {
humanOffset = Quaternion.AngleAxis (newValue, Vector3.right) * humanOffset;
}
Does decreaseCameraAngle cause problems as well? Why are using a variable that you are assigning in the quaternion? What is wrong with Transform.Rotate?
Hi there, this forum post contains what you are looking for here.
Here is the script in c#
public GameObject target;
float radius = 3f, angleX = 0f, angleY = -45f;
void Update()
{
radius -= Input.GetAxis("Mouse ScrollWheel") * Time.deltaTime * 100f;
angleX += Input.GetAxis("Mouse X") * Time.deltaTime;
angleY += Input.GetAxis("Mouse Y") * Time.deltaTime;
float x = radius * Mathf.Cos(angleX) * Mathf.Sin(angleY);
float z = radius * Mathf.Sin(angleX) * Mathf.Sin(angleY);
float y = radius * Mathf.Cos(angleY);
transform.position = new Vector3(x + target.transform.position.x,
y + target.transform.position.y,
z + target.transform.position.z);
transform.LookAt(target.transform.position);
}
For longer time to transition from mouse pointer and target area, change Time.deltaTime to Time.deltaTime/2 and Time.deltaTime/3 and so on. Hope this helped!
