Executing variables as code?

Questions & Answers
1

So i have this piece of code that is working like i want it to but its rather cumbersome. I wonder if there is a way to do this with a loop since al the lines are kinda the same except for some minor differences. If there is a way to use variables for these minor differences so i dont have to copy them manually it would be very nice.

Here is the code:

public void UpdateMenu(){
		Delay = 0;

		if (CurrentScroll > (Player.Inventory.Count-1)){
			Line1.text = "Nothing here scrub.....";
		}
		else {
			Line1.text = Player.Inventory[0+CurrentScroll].amount + " units of " + Player.Inventory[0+CurrentScroll].name;
			ResSp1.sprite = IDB.itemDB[0 + CurrentScroll].itemsprite;
		}

		if (CurrentScroll > (Player.Inventory.Count-2)){
			Line2.text = "-----------------------";
		}
		else {
			Line2.text = Player.Inventory[1+CurrentScroll].amount + " units of " + Player.Inventory[1+CurrentScroll].name;
			ResSp2.sprite = IDB.itemDB[1 + CurrentScroll].itemsprite;
		}

		if (CurrentScroll > (Player.Inventory.Count-3)){
			Line3.text = "-----------------------";
		}
		else {
			Line3.text = Player.Inventory[2+CurrentScroll].amount + " units of " + Player.Inventory[2+CurrentScroll].name;
			ResSp3.sprite = IDB.itemDB[2 + CurrentScroll].itemsprite;
		}

		if (CurrentScroll > (Player.Inventory.Count-4)){
			Line4.text = "-----------------------";
		}
		else {
			Line4.text = Player.Inventory[3+CurrentScroll].amount + " units of " + Player.Inventory[3+CurrentScroll].name;
			ResSp4.sprite = IDB.itemDB[3 + CurrentScroll].itemsprite;
		}

		if (CurrentScroll > (Player.Inventory.Count-5)){
			Line5.text = "-----------------------";
		}
		else {
			Line5.text = Player.Inventory[4+CurrentScroll].amount + " units of " + Player.Inventory[4+CurrentScroll].name;
			ResSp5.sprite = IDB.itemDB[4 + CurrentScroll].itemsprite;
		}

		if (CurrentScroll > (Player.Inventory.Count-6)){
			Line6.text = "-----------------------";
		}
		else {
			Line6.text = Player.Inventory[5+CurrentScroll].amount + " units of " + Player.Inventory[5+CurrentScroll].name;
			ResSp6.sprite = IDB.itemDB[5 + CurrentScroll].itemsprite;
		}

		if (CurrentScroll > (Player.Inventory.Count-7)){
			Line7.text = "-----------------------";
		}
		else {
			Line7.text = Player.Inventory[6+CurrentScroll].amount + " units of " + Player.Inventory[6+CurrentScroll].name;
			ResSp7.sprite = IDB.itemDB[6 + CurrentScroll].itemsprite;
		}


		if (CurrentScroll > (Player.Inventory.Count-8)){
			Line8.text = "-----------------------";
		}
		else {
			Line8.text = Player.Inventory[7+CurrentScroll].amount + " units of " + Player.Inventory[7+CurrentScroll].name;
			ResSp8.sprite = IDB.itemDB[7 + CurrentScroll].itemsprite;
		}


		if (CurrentScroll > (Player.Inventory.Count-9)){
			Line9.text = "-----------------------";
		}
		else {
			Line9.text = Player.Inventory[8+CurrentScroll].amount + " units of " + Player.Inventory[8+CurrentScroll].name;
			ResSp9.sprite = IDB.itemDB[8 + CurrentScroll].itemsprite;
		}


		if (CurrentScroll > (Player.Inventory.Count-10)){
			Line10.text = "-----------------------";
		}
		else {
			Line10.text = Player.Inventory[9 + CurrentScroll].amount + " units of " + Player.Inventory[9 + CurrentScroll].name;
			ResSp10.sprite = IDB.itemDB[9 + CurrentScroll].itemsprite;
		}

// Remove variables Line1 … Line10 and ResSp1 … ResSp10
// Use lists instead.
public List Lines = new List();
public List ResSp = new List();

public void UpdateMenu()
{
    for (int i = 0; i < 10; ++i)
        UpdateMenuEntry(i);
}

private void UpdateMenuEntry(int i)
{
    var line = Lines*;*

var resSp = ResSp*;*
var itemId = i + CurrentScroll;
var item = Player.Inventory[itemId];

if (CurrentScroll > (Player.Inventory.Count - (i + 1)))
{
line.text = “-----------------------”;
}
else
{
line.text = item.amount + " units of " item.name;
resSp.sprite = IDB.itemDB[itemId].itemsprite;
}
}
And if you want, you could group up the UI objects…
// If a Text and an Image belong together, make a class for them
[System.Serializable]
public class InventoryItemUI
{
public Text line;
public Image res;

public string Text { get { return line.text; } set { line.text = value; } }
public Sprite Sprite { get { return res.sprite; } set { res.sprite = value; } }

public void Clear()
{
Text = “-----------------------”;
// Sprite = blank?
}

public void Refresh(int itemId)
{
// I dont know if Player is a variable or a class.
// I dont know if IDB is a variable or a class.
var item = Player.Inventory[itemId];
Text = item.amount + " units of " item.name;
Sprite = IDB.itemDB[itemId].itemsprite;
}
}

public List inventoryItemUI = new List();

public void UpdateMenu()
{
for (int i = 0; i < inventoryItemUI.Count; ++i)
{
var item = inventoryItemUI*;*
if (CurrentScroll > (Player.Inventory.Count - (i + 1)))
item.Clear();
else
item.Refresh(i + CurrentScroll);}
}
}
