Camera Touch Control limit

Hello everybody ,

Thanks by advance for your time and sorry for my bad english

I use a Camera Touch control script for move my camera in a scene but the problem there is no limit , so the camera can move so far from the interest and is the same for the zoom

Can you please help me to edit the script ?
thanks a lot for your help

This is the script :

Code (CSharp):

1. using UnityEngine;
2. using System.Collections;
3.  
4. public class AdvancedCamera : MonoBehaviour {
5.    
6.     public float PanSpeed = 0.025F;
7.     public float PinchSpeed = 0.05F;
8.    
9.     // Use this for initialization, or not. That works too.
10.     void Start () {
11.        
12.     }
13.    
14.     // Update is called once per frame, of course.
15.     void Update () {
16.         // Check if we have one finger down, and if it's moved.
17.         // You may modify this first portion to '== 1', to only allow pinching or panning at one time.
18.         if (Input.touchCount > 0 && Input.GetTouch(0).phase == TouchPhase.Moved) {
19.             Vector2 touchDeltaPosition = Input.GetTouch(0).deltaPosition;
20.             // Translate along world cordinates. (Done this way so we can angle the camera freely.)
21.             transform.position -= new Vector3(touchDeltaPosition.x * PanSpeed, 0, touchDeltaPosition.y * PanSpeed);
22.         }
23.        
24.         // Check if we have two fingers down.
25.         if ( Input.touchCount == 2 )
26.         {
27.             Touch touch1 = Input.GetTouch( 0 );
28.             Touch touch2 = Input.GetTouch( 1 );
29.            
30.             // Find out how the touches have moved relative to eachother.
31.             Vector2 curDist = touch1.position - touch2.position;
32.             Vector2 prevDist = (touch1.position - touch1.deltaPosition) - (touch2.position - touch2.deltaPosition);
33.            
34.             float touchDelta = curDist.magnitude - prevDist.magnitude;
35.            
36.             // Translate along local coordinate space.
37.             Camera.main.transform.Translate(0, 0, touchDelta * PinchSpeed);  
38.         }
39.     }
40. }

I want add a minimum and maximum for the zoom and the movement , can you help me ?

Thanks .

 

Did you ever figure out your issue? Do you mind sharing? Thanks.

 

You should be able to just clamp the main camera's z components of its transform position at the end of the script.. Something like:

Code (csharp):

1. Camera.main.transform.Translate(0, 0, touchDelta * PinchSpeed);
2. Camera.main.transform.position.z = Mathf.Clamp(Camera.main.transform.position.z, <min distance>, <max distance>);
