I am working on a game project. I am adding items to a shopping cart when the player goes to frame 6 i want it to print the items in the cart.
Currently i am using a switch in the main of frame 6. This is long tiresome code.
What i want it to do is work through a loop, if the item code matches that array i want it to print the description, item code, and price on the screen

Here is the code that i have so far......any suggestions

stop();
//displays total cost
total_txt.text = "$" + totalCost;
//creates a text field for the items in the shopping cart
_root.createTextField("cartText", _root.getNextHighestDepth(), 100, 100, 500, 500);
//defines variables for the cart text format and an item in the shopping cart
var cartTextFormat = new TextFormat();
var item:String = "";
//specifies the format of the cartText field
cartTextFormat.multiline = true;
cartTextFormat.color = 0xffffff;
cartTextFormat.font = "Segoe Script";
//displays the header in the cartText field
cartText.text = "Items In Cart\t\t\t\t\t\t\tPrices\n";
 
//loops through the cart to display the items and costs of the items in the cartText field
for(var i = 0; i < cart.length; i++){
	item = cart[i];
	switch(item){
		case "blueshirt":
			cartText.text += "Long Sleeved Blue Blouse\t\t\t\t$" + itemPrices[i] + "\n";
			break;
		case "redblackshirt":
			cartText.text += "Red & Black Ripped Shirt\t\t\t\t$" + itemPrices[i] + "\n";
			break;
		case "shoe2":
			cartText.text += "Pink Sandals\t\t\t\t\t\t\t$" + itemPrices[i] + "\n";
			break;
	}
}
//sets the format to the cartText field
cartText.setTextFormat(cartTextFormat);

If you create a class called item and store those in an cart array you can override the toString method in the class to print the details of Item.


for(var i = 0; i < cart.length; i++)
{
     item = cart[i];
     sysout(item.toString());
}

I am not sure why you need to compare using the switch case.

Like a_b said, you shouldn't be even using a switch statement to do this.

I personally think you should make cart an object, with properties itemNames and itemPrices in it.

However, your code seems to be working, so I don't get your problem.

You will need to give more details.

I would like to be able to do this without the switch...
Ideally what i would like to do is be able to read through the cart, print the array, give option to remove from cart, (have it leave the screen) and adjust the price of the cart.
I have it working with putting a cart.text command on each item.

You would be interested in looking at the fla file. I think you would see more of what i mean.

I don't see the .fla file.

Actually this is what I think you should do.

Let cart be the array of items.
cart.ItemName be an array of items'  names, such asLong Sleeved Blue Blouse
cart.ItemPrice be an array of items' prices.

Then your code can get rid of the swtich statement. See code snippet.

Then of course for the other two parts you should be more clear on what you want.

If you would attach a .fla file with comments specifically on what you want to do, then it would be easy.

for(var i = 0; i < cart.length; i++) {
        item = cart[i];
        cartText.text += cart.itemName + "\t\t\t\t$" + cart.ItemPrice[i] + "\n";
}

It would work but there is a slight mistake with my code anyway.

It's cart.ItemName[i] not cart.ItemName.

Anyway to attach the .fla file, rename it to .txt extension and upload it here. Otherwise you can use upload elsewhere.
