How to flip 2d GameObject based on direction?

I have a 2d ant that moves to wherever you click in the world. I want to flip the ant’s sprite based on which direction it’s moving.
Here’s my current code (“target” is the clicked destination):

if(transform.position.x > target.x || transform.position.x < target.x)
		transform.Rotate(new Vector3(0,180,0));

Now, obviously, this just flips the ant 180 degrees for every frame until it reaches its destination.

Anyone have any suggestions on how to flip it only once based on the direction it’s going? (in C#, if possible.)


How about:

if (transform.position.x < target.x) {
    transform.rotation = Quaternion.identity;
else {
    transform.rotation = Quaternion.Euler(0,180,0);

Quaternion.identity is no rotation. This sets the rotation every frame. If you were going to have a bizillion sprites with this script, I might check the current direction and only reset the rotation if it is different, but for just a few…
