Third Person Shooter help?

Hi friends,

I am building this Third Person Shooter game, I already have the basic animations for the character such as Walk, Run, etc... I am having trouble making the character draw a weapon. Also, I want the left hand of the character to be in the gun. I know the Inverse Kinematics (IK) is used for this, but I don't really know IK.

Can anyone help me with this or reference me to a tutorial? Thanks in advance.

Here is a sample of my code:

using UnityEngine; using System.Collections;

[RequireComponent(typeof(Animator))] [RequireComponent(typeof(CapsuleCollider))] [RequireComponent(typeof(Rigidbody))] public class CharacterControl : MonoBehaviour {

     public float animSpeed = 1.5f;                
     
     public float walkSpeed = 4.0f;
     public float runSpeed = 8.0f;
     private Animator anim;                            
     private AnimatorStateInfo currentBaseState;            
     private CapsuleCollider col;                    
     private bool run = false;
     private bool IsGrounded = true;
     private bool strafeR = false;
     private bool strafeL = false;
     static int idleState = Animator.StringToHash ("Base Layer.Idle");
     static int walkState = Animator.StringToHash ("Base Layer.Walk");                
     static int strafeLeft = Animator.StringToHash ("Base Layer.StrafeLeft");
     static int strafeRight = Animator.StringToHash ("Base Layer.StrafeRight");
     static int runState = Animator.StringToHash ("Base Layer.Run");
     static int jumpState = Animator.StringToHash ("Base Layer.Jump");

     void Start ()
     {
             // initialising reference variables
             anim = GetComponent<Animator> ();
             col = GetComponent<CapsuleCollider> ();
             if (anim.layerCount == 2)
                     anim.SetLayerWeight (1, 1);
             run = false;
             strafeR = false;
             strafeL = false;
     }

     void FixedUpdate ()
     {
             float h = Input.GetAxis ("Horizontal");                
             float v = Input.GetAxis ("Vertical");                
             anim.SetFloat ("Speed", v);                             
             anim.SetFloat ("Direction", h);                                 
             anim.speed = animSpeed;                                
             anim.SetLookAtWeight (lookWeight);                    
             currentBaseState = anim.GetCurrentAnimatorStateInfo (0);    

             CheckRun ();
             StrafeWalk ();
     }

     void OnCollisionEnter (Collision collider)
     {
             IsGrounded = true;
     }

     public void CheckRun ()
     {
             if (Input.GetKey (KeyCode.LeftShift))
                     run = true;
             else
                     run = false;
     
     
             if (run == true) {
         
                     anim.SetBool ("Run", true);
             }
             if (run == false) {
         
                     anim.SetBool ("Run", false);
             }
     }

     public void StrafeWalk ()
     {
             if (Input.GetKey (KeyCode.Q)) 
                     strafeL = true;
              else 
                     strafeL = false;
             
             
             if (strafeL == true) {
                     anim.SetBool ("StrafeL", true);
             }
             if (strafeL == false) {
                     anim.SetBool ("StrafeL", false);
             }

             if (Input.GetKey (KeyCode.E)) 
                     strafeR = true;
             else 
                     strafeR = false;
             
             if (strafeR == true) {
                     anim.SetBool ("StrafeR", true);
             }
             if (strafeR == false) {
                     anim.SetBool ("StrafeR", false);
             }
     }

}
