Move character in unity

I am new to unity and was wandering how to move a character so that it will stop when it hits a wall.

Currently i have used code like this:

Vector3 pos = transform.position;
if(Input.GetKey("a")) pos.x -= 1;
if(Input.GetKey("d")) pos.x += 1;
transform.position = pos;

However with this the character will move through walls. I have added a rigidbody component to the char.

EDIT: Yes they do have a box collider on them, and the char does actually start to "bounce" when they collide, but the char goes right through the wall.

You need to let the Physics engine do the moving for you, so don't set the transform.position yourself. Set the rigidbody.velocity instead.

int xVelocity = 0;
if(Input.GetKey("a"))
{
    xVelocity = -1;
}
else if(Input.GetKey("d"))
{
    xVelocity = 1;
}

rigidbody.velocity = new Vector3(xVelocity, 0, 0);
