Unable to rotate 2D player around Y axis

I'm trying to make my player character face the direction its walking toward in a 2D game. Supposedly simple. Yet I can't make it happen.

The code looks like this :

Code (CSharp):

1. if (movement.x < Vector3.zero.x)
2.             {
3.                 Debug.Log("LEFT");
4.                 transform.Rotate(new Vector3(0, 180,0));
5.  
6.             }
7.             else
8.             {
9.                 Debug.Log("RIGHT");
10.                 transform.Rotate(new Vector3(0, 0, 0));
11.             }

I've tried several version of this, including modifying rotate directly, as well as using LocalTransform. None of this seems to have any impact on my PC : there is absolutely no change on the editor or ingame. It detects the input (the Debug.log work) but no impact.

Funnily enough, it works when my player swims, not when it walks. When it swims, i use this version (which doesn't work when I walk) :

Code (CSharp):

1.  
2.  
3.                 transform.localRotation = Quaternion.Euler(0, 180, -90);
4.  

Any idea of what I could be missing ?

 

use

Code (CSharp):

1. transform.localscale = new vector3(-1,1,1);

 

Thanks raarc : it kind of works, but it's having cascading effects on children of the PC. I have a torch that follows the player's mouse, and using you method makes it work only when the player looks right. Anyway to make it work with rotate, so everything rotates ?

 

Hi @PaulKhill

Don't rotate your object... you are literally telling your object to "rotate" relative to current orientation. It is usually better to set rotation value to a specific value you want (or rotate towards this target value).

Code (CSharp):

1. if (Input.GetKeyDown(KeyCode.Space))
2. {
3.     flipped = !flipped;
4.  
5.     if (flipped)
6.         tra.rotation = Quaternion.Euler(0, -180, 0);
7.     else
8.         tra.rotation = Quaternion.Euler(0, 0, 0);
9. }

Although personally I would only make the sprite flip using SpriteRenderer's flipX toggle. But if you have a hierarchy of objects then you might have to move those by code to match flipped sprite, so in this case I guess rotating GameObject might work better for you.

 

Thanks for the answer, I'd have prefered to go with the flip method, but it'd just get messy with the childs indeed.

I've already tried to set the rotation directly :

Code (CSharp):

1. if (movement.x < Vector3.zero.x)
2.             {
3.                 Debug.Log("LEFT");
4.                 transform.rotation = Quaternion.Euler(0, 0, 0);
5.  
6.             }
7.             else
8.             {
9.                 Debug.Log("RIGHT");
10.                 transform.rotation = Quaternion.Euler(0, -180, 0);
11.             }

But for some reason, although it definitly reads it(DebugLog shows), it has no impact on the rotation of the object (the numbers aren't even switching in the editor). Any other cues ? What am I missing ?

 

I tested it before pasting it here. The example I gave works.

Maybe you are setting your rotation somewhere else too?

 

Thanks, eses ! I was indeed setting my rotation elsewhere too (triggered by a collision that was too large for its own good).
