Ray cast affects all colliders in scene if mouse button is not releasesd.

Question

To be specific i have some drawers in my scene and i want to open-close them by click and drag them to open-close. Each drawer has a collider atached. When i hit the first drawer it opens-closes corectlly but before i release the mouse button and move the mouse pointer over another drawer or all drawers in scene, all of them starts to open at once.

What i want is to click a drawer and drag it to open-close it, the click another one and so on. I know that a way to do this is by using tags or layers but i am not very good at scripting yet.

Here is the code.

 public GameObject drawer;
 
     void Update () {
         if (Input.GetMouseButton(0)) {
             RaycastHit hit;
             Ray ray = Camera.main.ScreenPointToRay (Input.mousePosition); 
             if (Physics.Raycast (ray, out hit, 100.0f)) {
                 drawer = hit.collider.gameObject;
             }
 
             if (drawer != null ) {
                 translate_z += Input.GetAxis ("Mouse Y") * sensX * Time.deltaTime;
                 translate_z += Input.GetAxis ("Mouse X") * sensX * Time.deltaTime;
                 translate_z = Mathf.Clamp (translate_z, -1.25f, 0.0f);
                 drawer.transform.localPosition = new Vector3 (0.0f, 0.0f, translate_z);
             }
         } else {
         //drawer = null;
         }
     }

I think you want something like

 4: if inputgetmouse && !isDragging (new bool)
 11.5/newline isDraggging = true;
 19.5/newline  if(input.getmouseup) isDragging = false

Something to capture the state of dragging and only do stuff when you aren't dragging.

Thanks man for your answer. I adjusted my code as you mention and now it works great.

Here is the corrected code.

 using UnityEngine;
 using System.Collections;
 
 public class draw : $$anonymous$$onoBehaviour {
 
     float translate_z;
     float translate_new_z;
     float sensX = 2.0f;
     public GameObject drawer;
     public bool isDraging;
 
     void Update () {
         if (Input.Get$$anonymous$$ouseButton (0)) {
             if (!isDraging) {
                 RaycastHit hit;
                 Ray ray = Camera.main.ScreenPointToRay (Input.mousePosition); 
                 if (Physics.Raycast (ray, out hit, 100.0f)) {
                     drawer = hit.collider.gameObject;
                     isDraging = true;
                 }
             }
 
             if (isDraging) {
                 translate_z += Input.GetAxis ("$$anonymous$$ouse Y") * sensX * Time.deltaTime;
                 translate_z += Input.GetAxis ("$$anonymous$$ouse X") * sensX * Time.deltaTime;
                 translate_z = $$anonymous$$athf.Clamp (translate_z, -1.25f, 0.0f);
                 drawer.transform.localPosition = new Vector3 (0.0f, 0.0f, translate_z);
                 translate_new_z = drawer.transform.localPosition.z;
                 Debug.Log (translate_new_z);
             }
         } else if (Input.Get$$anonymous$$ouseButtonUp(0)) {
             isDraging = false;
         }
     }
 }

Ray cast affects all colliders in scene if mouse button is not releasesd.
