Creating a function to use as an event in an animation?

You need to have these things:

• A trigger that will detect the sword on the ground/closet

• A bone/empty object parented to the palm, this will serve as the parent of the sword, you need to orientate this bone/object so that when the sword is held, the sword has the correct orientation

  Steps

1. Detect for sword

2. If pick-up key is pressed, and sword is detected, Go to step 3; else go back to Step 1

3. Play pick-up animation; Time step 4 and 5 correctly using animation event

4. Copy the orientation of the sword-parent to the sword itself

5. Parent the sword to the sword-parent

   Example script

   public class PickUp : MonoBehaviour { public Transform swordParent; private Transform sword;

    void Update() {
          if( Input.GetKeyDown( KeyCode.C ) && sword != null ) {
             animation.Play("Pickup");
          }
       }
    
       void OnTriggerEnter( Collider other ) {
          if( other.gameObject.CompareTag("Sword") ) {
             sword = other.gameObject.Transform ; 
          }
       }
    
       void OnTriggerExit( Collider other ) {
          if( other.gameObject.Transform == sword ) {
             sword = null; 
          }
       }
    
       void PickUpSword() {
          sword.parent = swordParent;
    
          sword.localLocation = Vector3.zero;
          sword.localRotation = Quaternion.identity;
          sword.localScale = Vector3.one;
       }
    }
   
   

You will insert an animation-event in the Pickup animation clip to call the PickUpSword(). Please note that this is an example, you will have to do the integration yourself as I do not know how you structure/write your script.

You can even split the detecting function to another script, for example: SwordDetectArea.cs; so in your animation-controller script, you will do something like this:

 if( Input.GetKeyDown( KeyCode.C ) && swordDetectArea.sword != null ) {
    ...
 }
