Camera problems Mouse Scroll Wheel + Padding

[michael_bricout]

Hi,

I’m working on my camera script :

Here it is :

using UnityEngine;
using System.Collections;

public class CameraControl_Basic : MonoBehaviour {

public Transform m_CameraTarget;
public float m_Distance = 80.0f;
public float xSpeed = 4.0f;
public float ySpeed = 4.0f;
public int yMinLimit = -50;
public int yMaxLimit = 80;
public float minDist = 5.0f;
public float maxDist = 5.0f;
public float m_MinElevation = -30.0f;
public float m_MaxElevation = 30.0f;
private float m_x = 0.0f;
private float m_y = 0.0f;

// Use this for initialization
void Start ()
{
UpdateCamera();
}

// Update is called once per frame
void Update ()
{
if (m_CameraTarget )
{
bool input = false;

// Left Mouse Orbit
if ( Input.GetMouseButton(0) )
{
input = true;
m_x += Input.GetAxis(“Mouse X”) * xSpeed;
m_y -= Input.GetAxis(“Mouse Y”) * ySpeed;
m_y = ClampAngle(m_y, yMinLimit, yMaxLimit);
Debug.Log(“bouton gauche enfonce”);
}

if ( Input.GetMouseButton(1) )
{
input = true;
m_Distance -= Input.GetAxis(“Mouse Y”) * ySpeed;

if (m_Distance < minDist) m_Distance = minDist;
if (m_Distance > maxDist) m_Distance = maxDist;
Debug.Log(“bouton droit enfonce”);
}

if ( Input.GetMouseButton(2))
{
input = true;

Vector3 tmp = m_CameraTarget.position;
tmp.y = tmp.y - ( Input.GetAxis(“Mouse Y”) * ySpeed);
tmp.x = tmp.x - ( Input.GetAxis(“Mouse X”) * ySpeed);

if (tmp.y < m_MinElevation) tmp.y = m_MinElevation;
if (tmp.y > m_MaxElevation) tmp.y = m_MaxElevation;

m_CameraTarget.position = tmp;
Debug.Log(“molette enfoncee”);
}

if (input) UpdateCamera();
}
}

public void UpdateCamera ()
{
Vector3 dist = new Vector3(0.0f, 0.0f, -m_Distance);
Quaternion rotation = Quaternion.Euler(m_y, m_x, 0.0f);
Vector3 position = rotation * dist + m_CameraTarget.position;

transform.rotation = rotation;
transform.position = position;
}

/*
void AdjustElevation ()
{
Vector3 tmp = m_CameraTarget.position;
tmp.y = tmp.y + ( Input.GetAxis(“Mouse Y”) * ySpeed);

if (tmp.y < m_MinElevation) tmp.y = m_MinElevation;
if (tmp.y > m_MaxElevation) tmp.y = m_MaxElevation;

m_CameraTarget.position = tmp;
}

void AdjustZoom ()
{
m_Distance -= Input.GetAxis(“Mouse Y”) * ySpeed;
if (m_Distance < minDist) m_Distance = minDist;
}
*/

float ClampAngle ( float angle, float min, float max)
{
if (angle < -360) angle += 360;
if (angle > 360) angle -= 360;
return Mathf.Clamp (angle, min, max);
}
}

Here is what I’m looking for :

• If you press the RIGHT mouse button and move the mouse, you zoom on the object. It works

• If you press the LEFT mouse button and move the mouse, you turn around the object It works

1. If you scroll the mouse wheel you zoom on the object It doesn’t work, can you help me ? [/COLOR]

2. If you press RIGHT and LEFT button of your mouse, you move the camera in X and Y axes (padding) It works only with the mouse scroll wheel button, but I want to use the RICHT and LEFT button. It doesn’t work, can you help me ?[/COLOR]

• If you DON’T press RIGHT and LEFT button of your mouse and you move the camera, nothing happend. The camera don’t move. It works

Does someone can help me to solve my problems ?

Thanks for your help !

Nobody can help me ?

I really need to solve my problem …

Hi !

I can use the mouse scroll wheel to zoom now :

Here the code :

using UnityEngine;
using System.Collections;

public class CameraControl_Basic : MonoBehaviour {

public Transform m_CameraTarget;
public float m_Distance = 80.0f;
public float xSpeed = 4.0f;
public float ySpeed = 4.0f;
public int yMinLimit = -50;
public int yMaxLimit = 80;
public float minDist = 5.0f;
public float maxDist = 5.0f;
public float m_MinElevation = -30.0f;
public float m_MaxElevation = 30.0f;
private float m_x = 0.0f;
private float m_y = 0.0f;

// Use this for initialization
void Start ()
{
UpdateCamera();
}

// Update is called once per frame
void Update ()
{
if (m_CameraTarget )
{
bool input = false;

// Left Mouse Orbit
if ( Input.GetMouseButton(0) )
{
input = true;
m_x += Input.GetAxis(“Mouse X”) * xSpeed;
m_y -= Input.GetAxis(“Mouse Y”) * ySpeed;
m_y = ClampAngle(m_y, yMinLimit, yMaxLimit);
Debug.Log(“bouton gauche enfonce”);
}

if ( Input.GetMouseButton(1) )
{
input = true;
m_Distance -= Input.GetAxis(“Mouse Y”) * ySpeed;

if (m_Distance < minDist) m_Distance = minDist;
if (m_Distance > maxDist) m_Distance = maxDist;
Debug.Log(“bouton droit enfonce”);
}

if ( Input.GetMouseButton(2))
{
input = true;
Vector3 tmp = m_CameraTarget.position;
tmp.y = tmp.y - ( Input.GetAxis(“Mouse Y”) * ySpeed);
tmp.x = tmp.x - ( Input.GetAxis(“Mouse X”) * ySpeed);

if (tmp.y < m_MinElevation) tmp.y = m_MinElevation;
if (tmp.y > m_MaxElevation) tmp.y = m_MaxElevation;

m_CameraTarget.position = tmp;
Debug.Log(“molette enfoncee”);
}

if (Input.GetAxis(“Mouse ScrollWheel”) != 0){
input = true;
m_Distance -= Input.GetAxis(“Mouse ScrollWheel”) * ySpeed;

if (m_Distance < minDist) m_Distance = minDist;
if (m_Distance > maxDist) m_Distance = maxDist;
Debug.Log(“molette tourne”);
}

if (input) UpdateCamera();
}
}

public void UpdateCamera ()
{
Vector3 dist = new Vector3(0.0f, 0.0f, -m_Distance);
Quaternion rotation = Quaternion.Euler(m_y, m_x, 0.0f);
Vector3 position = rotation * dist + m_CameraTarget.position;

transform.rotation = rotation;
transform.position = position;
}

/*
void AdjustElevation ()
{
Vector3 tmp = m_CameraTarget.position;
tmp.y = tmp.y + ( Input.GetAxis(“Mouse Y”) * ySpeed);

if (tmp.y < m_MinElevation) tmp.y = m_MinElevation;
if (tmp.y > m_MaxElevation) tmp.y = m_MaxElevation;

m_CameraTarget.position = tmp;
}

void AdjustZoom ()
{
m_Distance -= Input.GetAxis(“Mouse Y”) * ySpeed;
if (m_Distance < minDist) m_Distance = minDist;
}
*/

float ClampAngle ( float angle, float min, float max)
{
if (angle < -360) angle += 360;
if (angle > 360) angle -= 360;
return Mathf.Clamp (angle, min, max);
}
}

Now I need to move (padding) ma camera by pressing the LEFT and RIGHT mouse button …

Thanks for your help !

Try something like this to make the code a little more straight forward.

enum CameraAction {
    None,
    Zoom,
    Orbit,
    Move,
}

static CameraAction GetCameraAction() {
    bool left = Input.GetMouseButton(0), right = Input.GetMouseButton(1);
    return left ? ( right ? CameraAction.Move : CameraAction.Orbit ) : ( right ? CameraAction.Zoom : CameraAction.None );
}

then change your update a bit:

void Update () 
{	
    CameraAction cameraAction = GetCameraAction();
    if ( !m_CameraTarget ) cameraAction = CameraAction.None;// do nothing without target.

    switch(cameraAction) {
        case CameraAction.Orbit:
            input = true;	
            m_x += Input.GetAxis("Mouse X") * xSpeed; 
            m_y -= Input.GetAxis("Mouse Y") * ySpeed;
            m_y = ClampAngle(m_y, yMinLimit, yMaxLimit);
            Debug.Log("bouton gauche enfonce");
            break;
        case CameraAction.Zoom:
            m_Distance -= Input.GetAxis("Mouse Y") * ySpeed;

            if (m_Distance < minDist) m_Distance = minDist;	
            if (m_Distance > maxDist) m_Distance = maxDist;
            Debug.Log("bouton droit enfonce");
            break;
        case CameraAction.Move:
            {
                Vector3	tmp = m_CameraTarget.position;	
                tmp.y = tmp.y - ( Input.GetAxis("Mouse Y") * ySpeed);
                tmp.x = tmp.x - ( Input.GetAxis("Mouse X") * ySpeed);

                if (tmp.y < m_MinElevation) tmp.y = m_MinElevation;
                if (tmp.y > m_MaxElevation) tmp.y = m_MaxElevation;

                m_CameraTarget.position = tmp;	
                Debug.Log("molette enfoncee");
                break;
       default: break;
    }
    if( cameraAction != CameraAction.None ) UpdateCamera();
}

And that should solve number 4.

unsure about how scroll wheel works unfortunatly.

[michael_bricout]

Thanks for your help but it seems to dosen’t work.

I’m not a programmer, so …

I need to know how I to ma ke an action by pressing the 2 mouse button by script. I don’t know the code to do that.

Can you help me ?

Thanks

[bdev]

Your main problem with your first script you posted is

if(Input.GetMouseButton(0)) { … orbit … }
if(Input.GetMouseButton(1)) { … zoom … }
if(Input.GetMouseButton(2)) { … pan … }
when it should be:

if(Input.GetMouseButton(0) Input.GetMouseButton(1) ) { … pan … }
else if( Input.GetMouseButton(0) ) { … orbit … }
else if( Input.GetMouseButton(1) ) { … zoom … }

Perfect man !! It works many thanks for your help !
