2D sprite won't rotate

Questions & Answers
1

Hi, I have this script attached to a 2D sprite that is meant to take rotate to a different position based on which arrow theu ser presses. But in the vertical section, instead of rotating it to the direction the code specifies, it just set the sprite’s z rotation to 180. What did I do wrong?

function ChooseShotDirection(){


	
	if(Input.GetAxis("Fire Horizontal") > 0){

		transform.rotation.z = 0;
		transform.rotation.y = 180;

Debug.Log("Shot Right");


	}
			
	else if(Input.GetAxis("Fire Horizontal") < 0){

		transform.rotation.z = 0;
		transform.rotation.y = 0;

Debug.Log("Shot left");

	}						
									
												
															
	else if(Input.GetAxis("Fire Vertical") > 0){

		transform.rotation.z = 270;
		transform.rotation.x = 0;
		transform.rotation.y = 0;

Debug.Log("Shot Up");
	}
			
	else if(Input.GetAxis("Fire Vertical") < 0){

		transform.rotation.z = 90;
		transform.rotation.x = 0;
		transform.rotation.y = 0;

Debug.Log("Shot Down");

not sure what the problem is, but I don’t think you should be able to set the rotations correctly like that if you are using c#. Try this instead of setting the values separately.

transform.eulerAngles = new Vector3(xValue, yValue, zValue);

or

transform.rotation = Quaternion.Euler(new Vector3(xValue, yValue, zValue));

I manged to fix the issue like this. I set the sprite to its up position by default and saved it in the UpPosition var. Then for the horizontal rotations I did it conventional, but the vertical ones I referred to the UpPosition var and inverted it for down.

function ChooseShotDirection(){


	
	if(Input.GetAxis("Fire Horizontal") > 0){

		transform.rotation.z = 0;
		transform.rotation.y = 180;
		transform.rotation.x = 0;
	
		var TheShotR = Instantiate(Ammo, Right.position,  Quaternion.identity);		
		TheShotR.GetComponent(Transform).rotation = Quaternion.Euler(0, 0, 270);
		
//Debug.Log("Shot Right");


	}
			
	else if(Input.GetAxis("Fire Horizontal") < 0){

		transform.rotation.z = 0;
		transform.rotation.y = 0;
		transform.rotation.x = 0;
		
		var TheShotL = Instantiate(Ammo, Left.position, Quaternion.identity);		
		TheShotL.GetComponent(Transform).rotation = Quaternion.Euler(0, 0, 90);
		
//Debug.Log("Shot left");

	}						
									
												
															
	else if(Input.GetAxis("Fire Vertical") > 0){


		transform.rotation = UpPosition;
		transform.rotation.x = 0;
	
		var TheShotU = Instantiate(Ammo, Up.position, Quaternion.identity);
		//TheShotU.GetComponent(Transform).rotation = Quaternion.Euler(0, 0, 180);

//Debug.Log("Shot Up");
	}

			
						
												
	else if(Input.GetAxis("Fire Vertical") < 0){
		transform.rotation = UpPosition;
		transform.Rotate(180,180,0);
	

		var TheShotD = Instantiate(Ammo, Down.position,  Quaternion.identity);
		TheShotD.GetComponent(Transform).rotation = Quaternion.Euler(0, 0, 180);
//Debug.Log("Shot Down");
