Resolved [2D Top Down] How to ignore parent rotation ? My crosshair follow my player rotation animation

Hello everyone !

I'm working on my first project ! In my animation I rotated on the z axis my character so each time I move in a direction , my character is facing the right way.

I have a crosshair moving with my mouse position and follow my character with a magnitude, but each time I move in a direction with my keyboard, my crosshair rotate along with my character.

How do i ignore my parent rotation AND keep my parent transformation ? Do I need to change something in the animation inspector or in my script ?

Or is there simply an other way ?

I know that child inherits from their parents rotation/transformation, but I can't figure out how to keep my crosshair in the magnitude of my player and follow him without make him a child AND without breaking my script.

Here a GIF to better understand (crosshair is in tiny red and has too many opacity in gif sorry boyz, but u can guess it easily). U can see my bullets going the right way so my aiming script is "working" but my sprite isn't at the right place !



And here's the function I call in Update() in my script :

Code (CSharp):

1. private void AimAndShoot() {
2.         Vector2 shootingDirection = new Vector2(aim.x, aim.y);
3.  
4.         if (aim.magnitude > 0.0f) {
5.             crossHair.transform.localPosition = aim * 0.4f;
6.             crossHair.SetActive(true);
7.  
8.             shootingDirection.Normalize();
9.             if(endOfAiming) {
10.                 GameObject ammo = Instantiate(ammoPrefab, transform.position, Quaternion.identity);
11.                 ammo.GetComponent<Rigidbody2D>().velocity = shootingDirection * 3.0f;
12.                 ammo.transform.Rotate(0.0f, 0.0f, Mathf.Atan2(shootingDirection.y, shootingDirection.x) * Mathf.Rad2Deg);
13.                 Destroy(ammo, 2.0f);
14.             }
15.         } else {
16.             crossHair.SetActive(false);
17.          }
18.     }

 

It's hard to say without seeing your full hierarchy setup, but perhaps line 5 above you just set

.position

rather than

.localPosition

?

 

Hello Kurt, i'v tried that already but I had this problem : crosshair doesn't rotate anymore BUT doesn't follow my character movement :/

My Hierarchy is very simple I only have my player(parent)->crosshair(child)


Also I'm completely new sorry if I didn't understood the question or don't get obvious thing !

 

Oh then I think you need to do two things:

1. set the .position (as I noted above)

2. but set it to aim + your character's .position

The way this differs from simply setting .localRotation is that it does not rotate by the heading.

 

So I set my line like this for 1.

crossHair.transform.position = aim * 0.4f;

But I don't get what I need to do in the second part, can you give me a code example please ?

 

I was thinking about:

Code (csharp):

1. crossHair.transform.position = aim * 0.4f + thePlayer.transform.position;

 

It's working king, thank you so much, I can go to so sleep peacefully now
