Question by abhishakverma · Mar 13, 2014 at 03:35 PM · c#javascript

Rigidbody (Player) goes through wall

I have a game that player is the cube.That cube moves around.The cube has a rigidbody with box collier.When the player moves toward the wall, and touch the wall, a bit later, the player suddenly goes through. How to prevent a rigidbody to move through walls? #pragma strict

     // Move object using accelerometer
     var speed = 10;
      
      
      
     function Start () {
     Screen.sleepTimeout = SleepTimeout.NeverSleep;
      
      
     }
      
      
      
      
     function Update () {
      
      
      
     var dir : Vector3 = Vector3.zero;
      
      
      
     dir.x =/*Input.acceleration.x*5;*/ Input.GetAxis("Horizontal");//Input.acceleration.x*5;//Input.GetAxis("Horizontal");//-Input.acceleration.y;
      
     dir.z =/*Input.acceleration.y*2;*/Input.GetAxis("Vertical");//Input.acceleration.y*5;//Input.GetAxis("Vertical"); //Input.acceleration.x;
      
     // clamp acceleration vector to unit sphere
     if (dir.sqrMagnitude > 1)
     dir.Normalize();
      
     // Make it move 10 meters per second instead of 10 meters per frame...
     dir *= Time.deltaTime;
      
     // stop to cross movement
      
     if(Mathf.Abs(dir.x) > Mathf.Abs(dir.z)) {
     dir.z = 0;
     }
     else {
     dir.x = 0;
     }
      
     // Move object
     transform.Translate (dir * speed);
     }

The problem may be co$$anonymous$$g from your use of 'transform.Translate'. With Rigidbodies, I believe it's better to avoid Translating the transform and ins$$anonymous$$d use the Rigidbody component for movement.

can you help me how to use Rigidbody component in this script....thanks

You can use rigidbody.AddRelativeForce() to do it

And you should look at the wall, it has to have a collider in it!

Use this instead of transform.Translate();

 public float walkAcceleration = 5f;
 rigidbody.AddRelativeForce(Input.GetAxis("Horizontal") * walkAcceleration * Time.deltaTime, 0, Input.GetAxis("Vertical") * walkAcceleration * Time.deltaTime);

I am trying but not able to solve the problem.i want to this script work in mobile device too thatwhy i make like this only problem is Rigidbody (Player) goes through wall .please give me whole script that should work in device.thanks #pragma strict

 // $$anonymous$$ove object using accelerometer
     var speed = 2;
     
     
     function Start () {
      
    
     }
        
        
  
 
     function Update () {
      
 
     
     
         var dir : Vector3 = Vector3.zero;
 
         // we assume that device is held parallel to the ground
         // and Home button is in the right hand
         
         // remap device acceleration axis to game coordinates:
         //  1) XY plane of the device is mapped onto XZ plane
         //  2) rotated 90 degrees around Y axis
         
               
         dir.x =Input.acceleration.x;
         dir.z =Input.acceleration.z;
         
         // clamp acceleration vector to unit sphere
         if (dir.sqr$$anonymous$$agnitude > 1)
             dir.Normalize();
         
         // $$anonymous$$ake it move 10 meters per second ins$$anonymous$$d of 10 meters per frame...
         dir *= Time.deltaTime;
         
         // stop to cross movement
         
             if($$anonymous$$athf.Abs(dir.x) > $$anonymous$$athf.Abs(dir.z)) {
              dir.z = 0;
              }
          else {                  
                 dir.x = 0;
                }
             
         // $$anonymous$$ove object
         transform.Translate (dir * speed);
     }
