How can i add a collision detection for a character controller?

Questions & Answers

The problem is that my scripts work fine, except that the character walks trhough geometry even though it has a character controller attachhed to it.
I have two scripts. One named TP_Motor, and the other TP_Controller.
Here are the scripts:
TP_Motor

using UnityEngine;
using System.Collections;

public class TP_Motor : MonoBehaviour
{
public static TP_Motor Instance;

public float movementSpeed = 10;
public float backwardSpeed = 5;
public float Gravity = 40f;
public float TerminalVelocity = 20f;


private Vector3 slideDirection;

public float turningSpeed = 60;
public float MoveSpeed = 10f;
public float JumpSpeed = 14f;
public Vector3 MoveVector { get; set; }
public float VerticalVelocity { get; set; }


void Update() 
{
	Instance = this;
}

public void UpdateMotor() 
{
	 
	
	SnapAlignCharacterWithCamera();
	Moveandrotate();		
	ProcessMotion();
}

void Moveandrotate() // Esto hace que el jugador se mueva y rote.
	
	{
    float horizontal = Input.GetAxis("Horizontal") * turningSpeed * Time.deltaTime;
    transform.Rotate(0, horizontal, 0);
	
	
    float vertical = Input.GetAxis("Vertical") * movementSpeed * Time.deltaTime;
    transform.Translate(0, 0, vertical);
}

void ProcessMotion()
{
	// Transform MoveVector to World Space
	MoveVector = transform.TransformDirection(MoveVector);
	
	// Normalize MoveVector if Magnitude > 1
	if (MoveVector.magnitude > 1)
		MoveVector = Vector3.Normalize(MoveVector);
	
	// Multiply MoveVector by MoveSpeed Esto hace que se mueva de derecha a izquierda
	MoveVector *= MoveSpeed;
	
	// Reapply VerticalVelocity MoveVector.y
		MoveVector = new Vector3(MoveVector.x, VerticalVelocity , MoveVector.z);
	
	// ApplyGravity
	ApplyGravity();
	
	// Move Character in World Space Esto tambien hace que se mueva de derecha a izquierda
	TP_Controller.CharacterController.Move(MoveVector * Time.deltaTime);
}

void ApplyGravity()
{
	if (MoveVector.y > -TerminalVelocity)
		MoveVector = new Vector3(MoveVector.x, MoveVector.y - Gravity * Time.deltaTime, MoveVector.z);
	
	if(TP_Controller.CharacterController.isGrounded && MoveVector.y < -1)
		MoveVector = new Vector3(MoveVector.x, -1 , MoveVector.z);
		
}

public void Jump()
{
	if (TP_Controller.CharacterController.isGrounded)
		VerticalVelocity = JumpSpeed;
}

void SnapAlignCharacterWithCamera()
{

}

}

AND THE TP_Controller

using UnityEngine;
using System.Collections;

public class TP_Controller : MonoBehaviour
{
public static CharacterController CharacterController;
public static TP_Controller Instance;
public float MoveSpeed = 10f;

void Awake() 
{
	CharacterController = GetComponent();
	Instance = this;
}

void Update() 
{
	if(Camera.mainCamera == null)
		return;
	
	GetLocomotionInput();
	HandleActionInput();
	
	TP_Motor.Instance.UpdateMotor();
}


void GetLocomotionInput()
{
	var deadZone = 0.1f;
	
	TP_Motor.Instance.VerticalVelocity = TP_Motor.Instance.MoveVector.y; // Gravedad
	
	TP_Motor.Instance.MoveVector = Vector3.zero;
	
	if (Input.GetAxis("Vertical") > deadZone || Input.GetAxis("Vertical") < -deadZone)
		TP_Motor.Instance.MoveVector += new Vector3(0, 0, Input.GetAxis("Vertical"));
	
}

void HandleActionInput() // Esto hace junto con jump que se accione con un boton el Jump
{
	if (Input.GetButton("Jump"))
	{
		Jump ();
	}
}

void Jump()
{
	TP_Motor.Instance.Jump ();
}

}

Hi

make sure your walls or whatever object the character should collide with have colliders (and rigidbodies where needed) too.
