accessing the sprite renderer to flip the sprite? (C#) {SOLVED}

Im currently working on a 2D platformer and was wondering if there is some sort if script i could use/write so that when the A key is pressed the 'flip X' box in the sprite renderer is set to true? i know i will have to reference the sprite renderer but I'm not sure how to do this :s
I'm quite new to coding so any help is GREATLY appreciated

 

You'll need to do something like this. This script will have to be on the same gameObject as the SpriteRenderer component.

Make sure that the script name in the Editor is the same as the class name in the code.

Code (CSharp):

1. public class SpriteFlipper : MonoBehaviour
2. {
3.    // variable to hold a reference to our SpriteRenderer component
4.    private SpriteRenderer mySpriteRenderer;
5.  
6.    // This function is called just one time by Unity the moment the component loads
7.    private void Awake()
8.    {
9.         // get a reference to the SpriteRenderer component on this gameObject
10.         mySpriteRenderer = GetComponent<SpriteRenderer>();
11.    }
12.  
13.    // This function is called by Unity every frame the component is enabled
14.    private void Update()
15.    {      
16.         // if the A key was pressed this frame
17.         if(Input.GetKeyDown(KeyCode.A))
18.         {
19.             // if the variable isn't empty (we have a reference to our SpriteRenderer
20.             if(mySpriteRenderer != null)
21.             {
22.                  // flip the sprite
23.                  mySpriteRenderer.flipX = true;
24.             }
25.         }
26.     }
27. }

 

This worked a charm, thank you!

for anyone else that tries to use this method I had to add

Code (CSharp):

1. if(Input.GetKeyDown(KeyCode.D))
2.             {
3.                 // flip the sprite
4.                 mySpriteRenderer.flipX = false;
5.             }

in as well because if i tried to make the character walk in the opposite direction he ended up moonwalking haha.

 

I left that bit out hoping that you would expand on the solution on your own. Great job! Keep tinkering and editing and you'll be making your own scripts from scratch in no time.

 

Thanks for that code, it is really help me improve my coding skill

 

its pretty useful, but if you press the opposite key while holding down the other key, it will mean you are facing the wrong way

 

my imperfect solution
if (Input.GetButtonDown("Horizontal") && Input.GetAxisRaw("Horizontal") < 0)
{
// if the variable isn't empty (we have a reference to our SpriteRenderer
if (mySpriteRenderer != null)
{
// flip the sprite
mySpriteRenderer.flipX = true;
}

}
//if (Input.GetKeyDown(KeyCode.D))
if (Input.GetButtonDown("Horizontal") && Input.GetAxisRaw("Horizontal") > 0)
{
// flip the sprite
mySpriteRenderer.flipX = false;
}

 

Tq..Good work

 

how do i make it so i can turn the other way around again

 

Having a problem where sr.flipx causes other elements of my enemy script to fail
