Move camera slow on X axis

Archived Forums Questions & Answers

Hi, I need move camera +10 on X axis when press button like this:

	void FixedUpdate()
	{
		if(Input.GetKeyDown(KeyCode.A))
			transform.position = new Vector3(transform.position.x + 10f ,transform.position.y, transform.position.z);
		
		if(Input.GetKeyDown(KeyCode.D))
			transform.position = new Vector3(transform.position.x - 10f ,transform.position.y, transform.position.z);
	}

This works but the movement is too fast, I want change the position with a lower ‘velocity’.
I tried Lerp but doesnt work nice.
Thanks.

UPDATE:

Use this:

private const float MOVEMENT_TIME = 2.0f; // The object moves for 2 seconds
private const float MOVEMENT_DISTANCE = 10.0f; // Distance the object should move

void Update()
{
	if(Input.GetKeyDown(KeyCode.A))
	{
		StopCoroutine("MoveObject");
		StartCoroutine("MoveObject", MOVEMENT_DISTANCE);
	}
	
	if(Input.GetKeyDown(KeyCode.D))
	{
		StopCoroutine("MoveObject");
		StartCoroutine("MoveObject", -MOVEMENT_DISTANCE);
	}
}

private IEnumerator MoveObject(float distance)
{
	Vector3 currentPosition = this.transform.position;
	Vector3 targetPosition = new Vector3(this.transform.position.x + distance, this.transform.position.y, this.transform.position.z);
	float currentTime = 0.0f;

	while(currentTime <= MOVEMENT_TIME)
	{
		float movementFactor = currentTime / MOVEMENT_TIME;
		this.transform.position = Vector3.Lerp(currentPosition, targetPosition, movementFactor);
		currentTime += Time.deltaTime;
		yield return null;
	}
}

Within 2 seconds, the object moves 10 units on the X axis. You can change those values as you like.
