How to know if 2D gameobject is moving left or right?

You could do something like...

Vector2 oldLocation; Vector2 newLocation;

oldLocation = newLocation; newLocation = gameObject.transform.blahblah;

Do some fancy math, to determine if it's negative..or positive.

I hope you give Answer

Hi, to check which direction it's moving in in 2D, you'll check for changes to it's x transform.position value.

So in code it might look like:

 Vector2 posLastFrame;
 Vector2 posThisFrame;
 void Update()
 {
      posLastFrame = posThisFrame;
 
      posThisFrame = transform.position;
 
      CheckMoveDirection();
 }
 
 enum Direction { Right, Left, Still };
 Direction CheckMoveDirection()
 {
    if (posThisFrame.x > posLastFrame.x)
        return Direction.Right;
   if (posThisFrame.x < posLastFrame.x)
       return Direction.Left;
   else
      return Direction.Still;
 }
