Showcase Copy character position or pose from animation keyframe clip

Something that nobody asked for (I think)... but could be usefull.

In my scene I use the "death_animation" in a lot of my characters just to give a "feeling of mess" but this has a cost in performance so I decided to copy this " death pose" or "death Position" in a different prefab of my characters to use them without animation, animator or any script. But copy one by one of all the rigged components of different characters is a lot of work so I made this scripsts that works in the editor not in play mode

Copy Transfor Script:
This is the main script that make the work of copy all the position from one character to another.

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4.  
5. public class copyTransform : MonoBehaviour
6. {
7.     public Transform obj01;
8.     public Transform obj02;
9.     Transform[] transforms01;
10.     Transform[] transforms02;
11.     int transLength01;
12.     int transLength02;
13.  
14.     private TransformData transformDataOfObj01; //TransformData is a class that store and transfer the transform from
15.     private TransformData transformDataOfObj02; // one object to another
16.  
17.     public void transformThis()
18.     {
19.         transforms01 = obj01.GetComponentsInChildren<Transform>();
20.         transforms02 = obj02.GetComponentsInChildren<Transform>();
21.  
22.         transLength01 = transforms01.Length;
23.         transLength02 = transforms02.Length;
24.  
25.         if(transLength01 == transLength02) //MUST BE the same character with the same rigged structure
26.         {
27.          
28.             for (int i = 0; i <= transLength01; i++)
29.             {
30.                 transformDataOfObj01 = new TransformData(transforms01[i].transform);
31.                 transformDataOfObj01.ApplyTo(transforms02[i].transform);
32.             }
33.         }
34.         else
35.         {
36.             Debug.Log("Objects does not have the same childrens Length");
37.         }
38.  
39.  
40.     }
41. }

TransformData script is a class that store and transfer the transform from one object to another, this
script was made by user "derHugo" in this StackOverflow post: https://stackoverflow.com/questions/56794066/copying-all-the-transform-values-of-a-gameobject

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4.  
5. [SerializeField]
6. public class TransformData
7. {
8.     public Vector3 LocalPosition = Vector3.zero;
9.     public Vector3 LocalEulerRotation = Vector3.zero;
10.     public Vector3 LocalScale = Vector3.one;
11.  
12.     // Unity requires a default constructor for serialization
13.     public TransformData() { }
14.  
15.     public TransformData(Transform transform)
16.     {
17.         LocalPosition = transform.localPosition;
18.         LocalEulerRotation = transform.localEulerAngles;
19.         LocalScale = transform.localScale;
20.     }
21.  
22.     public void ApplyTo(Transform transform)
23.     {
24.         transform.localPosition = LocalPosition;
25.         transform.localEulerAngles = LocalEulerRotation;
26.         transform.localScale = LocalScale;
27.     }
28. }

finally add a custom Inspector button in the main CopyTransform script.This script MUST BE in a folder named "Editor" under the Asset folder. Find more info in here: https://learn.unity.com/tutorial/editor-scripting#5c7f8528edbc2a002053b5f8

Code (CSharp):

1. using UnityEngine;
2. using System.Collections;
3. using UnityEditor;
4.  
5. [CustomEditor(typeof(copyTransform))]
6. public class CopyTransBuilderEditor : Editor
7. {
8.     public override void OnInspectorGUI()
9.     {
10.         DrawDefaultInspector();
11.  
12.         copyTransform myScript = (copyTransform)target;
13.         if (GUILayout.Button("Copy Transform"))
14.         {
15.             myScript.transformThis();
16.         }
17.     }
18. }
19.  

Last, a video of how it works. I hope you find this usefull

 

Perfect!
I was just searching around for this functionality and found this post. The scripts work perfectly in 2021 LTS.

Muchas gracias Marck_ozz..

 

Thank you very much!
It works great. But I did some change, so, it's not necessary to duplicate the object and add the script. Here is my version:

Code (CSharp):

1.  
2. using UnityEditor;
3. using UnityEngine;
4. public class CopyTransform : MonoBehaviour
5. {
6.     [MenuItem("GameObject/SetPose", false, -10)] // now it show on right click on the object
7.     public static void SetPose()
8.     {
9.         TransformData transformDataOfObj01; //TransformData is a class that store and transfer the transform from
10.         TransformData transformDataOfObj02; // one object to another
11.        
12.         Transform obj01 = Selection.activeTransform; // get the clicked object
13.         Transform obj02 = Instantiate(obj01, obj01.position, obj01.rotation); //duplicate it
14.        
15.         Transform[] transforms01 = obj01.GetComponentsInChildren<Transform>();
16.         Transform[] transforms02 = obj02.GetComponentsInChildren<Transform>();
17.        
18.         int transLength01 = transforms01.Length;
19.         int transLength02 = transforms02.Length;
20.  
21.         if (transLength01 != transLength02) return; //MUST BE the same character with the same rigged structure
22.        
23.         for (int i = 0; i <= transLength01-1; i++)
24.         {
25.             transformDataOfObj01 = new TransformData(transforms01[i].transform);
26.             transformDataOfObj01.ApplyTo(transforms02[i].transform);
27.         }
28.            
29.         DestroyImmediate(obj02.GetComponent<Animator>()); //destroy the animator of the copy
30.     }
31. }
32.  

 

Hi PrisVas,

Thank you for sharing the new code. Do we still need the original code files from marck_ozz? Or we just need the codes you posted?

Thanks again,

 

@marck_ozz Thanks. This helped a lot. I used your code as a foundation for another use case. I have a LOD on my character components, and I turn off animation when far away, but the characters default to a T-Pose, which doesn't look good at a distance.

These scripts will set the default character pose at run time.

How to Use:
1. Add the CharacterPoser component to your character
2. Set the Parent transform
3. Open the unity Animation (Window > Animation > Animation)
4. Select an Animation and a key frame to the Pose you want
5. Click the SavePose button on CharacterPoser

16.         // Start is called before the first frame update
17.         void Start()
18.         {
19.             if (parent != null && data != null)
20.                 foreach (var d in data) d.Apply();
21.         }
