Have character's upper body follow mouse vertical movement.

Hello,

I am attempting to create a simple third-person shooter. I am having trouble getting my character's upper half to follow the vertical movement of my mouse.

I am able to have the upper half respond to my input but it makes the upper half twist and rotate in unexpected ways.

I noticed that the orientation of the spine on my character is rotated on two axes compared to the model as a whole.

If someone could point me in the right direction that would be appreciated.

Thanks,
Kent

This is my CameraController script.

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4.  
5. public class CameraController : MonoBehaviour {
6.     public float rotationHorizontalSpeed = 2.0F;
7.     public float rotationVerticalSpeed = 2.0F;
8.     public GameObject upperBody;
9.  
10.     // Use this for initialization
11.     void Start () {
12.      
13.     }
14.  
15.     // Update is called once per frame
16.     void Update () {
17.         float h = rotationHorizontalSpeed * Input.GetAxis("Mouse X");
18.         float v = rotationVerticalSpeed * Input.GetAxis("Mouse Y");
19.         transform.Rotate(v, h, 0);
20.     }
21.  
22.     private void LateUpdate()
23.     {
24.         //this.upperBody.transform.up = this.transform.forward;
25.         //this.upperBody.transform.forward = this.transform.right;
26.         //this.upperBody.transform.right = -this.transform.up;
27.     }
28. }

I think it's because you are rotating the transform relative to itself every frame. That means your rotations are affected by the previous rotations.

I'm not sure how you want your game to behave so I can't tell you how to go about correcting the problem.

You could try splitting your rotations onto separate gameobjects and only rotated x on one and y on the other.

Or

You could rotate relative to the parent transform

There are plenty of other solutions that may or may not be right for you.

 

Antony can you help me convert this to c sharp. Its the only script i can find that will move your spine with mouse movement but unity doesn't support c sharp anymore. Iv been stuck on this for hours. Help would be very much appreciated.

1. var sensitivityZ = 15F;
2. var minimumZ = -60F;
3. var maximumZ = 60F;
4. var rotationZ = 0F;
5. function LateUpdate ()
6. {
7. rotationZ += Input.GetAxis("Mouse Y") * sensitivityZ;
8. rotationZ = Mathf.Clamp (rotationZ, minimumZ, maximumZ);
10. transform.localEulerAngles = new Vector3(0, transform.localEulerAngles.y,rotationZ);
12. }
14. function Start ()
15. {
16. // Make the rigid body not change rotation
17. if (rigidbody)
18. rigidbody.freezeRotation = true;
19. }

 

replace 'var' with float

replace 'function' with void

put everything inside a class. (which is created for you if you create a new script from unity)

 

Thank you for replying Antony. But i already tried that and tried it again but it wont work. something about API's keeps popping up and I've tried to fix it in many ways. If its fine with you could you create a script that would allow my back to bend with up and down camera movement. Im creating a third person shooter and need it for my shooting script. I want to apply the script to my back bone segments.For Example:

https://www.crazygames.com/game/warscrapio

see how the players back rotates when you move the camera up and down but their is a limit to how far you can extend. That is what i am looking for. I understand this is a lot to ask for but i am new to unity and coding so help would be appreciated.

 

It's probably better you learn yourself. If you get others to write your code without the understanding then you won't be able to fix problems of add to the code later on. You will just run into more and more issues as you continue to develop your game.

 

I understand, I'll just keep on trying. By the way i tried out Major Mayhem and I love your work! thanks for replying.

 

Sorry for asking so many questions, but i made this script and i'm having some errors. As you know, I'm trying to make my character look up and down with the camera. I applied this script to the Spine but it makes my body rotate in weird ways. It still looks up and down but my spine is twisted sideways. I've scanned the forums and it probably has something to do with my spine rotation. If you could point me in the right direction it would be appreciated.

public Transform Spine;
void LateUpdate()
{
Spine.rotation = Quaternion.LookRotation(Camera.main.transform.forward, Spine.up);
Spine.transform.Rotate(0, 0, 30);
}

 

you're probably rotating around the wrong axis.

Spine.transform.Rotate(30, 0, 0);

If that doesn't fix it then I don't know enough about your game to help you.
