C# Camera scroll distance limit

using UnityEngine;
using System.Collections;

public class Screen_Movement : MonoBehaviour {
	public GameObject Camera;
	public float speed = 0.2f;
	
	void Start(){
	}
	
	void Update(){
	if(Input.GetAxis ("Mouse ScrollWheel") > 0)
	{
		Camera.transform.position = new Vector3(Camera.transform.position.x, Camera.transform.position.y - (1 * speed), Camera.transform.position.z);
	}
	if(Input.GetAxis ("Mouse ScrollWheel") < 0)
	{
		Camera.transform.position = new Vector3(Camera.transform.position.x, Camera.transform.position.y + (1 * speed), Camera.transform.position.z);
	}
	if(Input.mousePosition.x >= (Screen.width * 0.9))
	
	//Camera movement when the cursor is beyond a certain point of the screen
	{
		Camera.transform.position = new Vector3(Camera.transform.position.x + (1 * speed), Camera.transform.position.y, Camera.transform.position.z);
	}
	if(Input.mousePosition.x <= (Screen.width * 0.1))
	{
		Camera.transform.position = new Vector3(Camera.transform.position.x - (1 * speed), Camera.transform.position.y, Camera.transform.position.z);
	}
	if(Input.mousePosition.y >= (Screen.height * 0.9))
	{
		Camera.transform.position = new Vector3(Camera.transform.position.x, Camera.transform.position.y, Camera.transform.position.z + (1 * speed));
	}
	if(Input.mousePosition.y <= (Screen.height * 0.1))
	{
		Camera.transform.position = new Vector3(Camera.transform.position.x, Camera.transform.position.y, Camera.transform.position.z - (1 * speed));
	}
		
	}
}

This is the code that I have for movement throughout my RTS map. I have been experimenting with different ideas to limit the scroll in or out distance, but I haven’t been successful. Any ideas?

Just add check if y position is less than limitDistance when trying to scroll up.

if(Input.GetAxis ("Mouse ScrollWheel") > 0  Camera.transform.position.y<limitDistance)
{
    Camera.transform.position = new Vector3(Camera.transform.position.x, Camera.transform.position.y - (1 * speed), Camera.transform.position.z);
}

I actually created 2 more if statements to counter-act the Mouse ScrollWheel if statements… the I looked at yours and now I feel really dumb.
