Scroll List Problem
I want to create an item menu controllable by arrow keys, much so like the one in most Final Fantasy Games and various other JRPGs. So I chose to use a selection grid.
Now, this is currently my OnGUI function:
function OnGUI()
{
scrollPosition = GUI.BeginScrollView(Rect (10,10,220,300),scrollPosition, Rect (0, 0, 220, 400));
for(var i : ConsumableItem in itemBag)
{
//Reason: Using a built-in array
var newBag = new Array(selectionStrings);
//Add the item to the temp bag
//var newItemName : String = (i.name + " : " + i.itemAmount);
newBag.Add(i.name);
Debug.Log(i.name + " has been picked up");
//Add the contents of the temporary bag into the main bag
selectionStrings = newBag.ToBuiltin(String);
}
selectionGridInt = GUILayout.SelectionGrid (activeSelected, selectionStrings, 1, GUILayout.Width(200));
GUI.EndScrollView();
}
The list is to automatically populate as I add new items, (which it appears to be doing in the inspector), however, I can't keep it from duplicating the same entry repeatedly, (and i know the reason for that is because of my loop)
I was able to copy your code into a script and run it without problems (I did translate to C# first), so the issue is likely elsewhere in your code. Can you send us the specific errors you're getting, and under what circumstances they occur?
I tested the very bottom piece of code, the one you said produced errors:
var selGridInt : int = 0;
var selStrings : String[] = ["Grid 1", "Grid 2", "Grid 3", "Grid 4"];
function OnGUI () {
selGridInt = GUILayout.SelectionGrid (selGridInt, selStrings, 2);
}
In addition to C#, I tried it in Javascript and it worked just fine.
Figured it out (how silly of me). I just needed to add the entry of the item in the same function that I add the item to the actual inventory's array.
One array holds the string (stringArray) The other array holds the item (itemArray)
When I add an item to the itemArray, I add a string to the stringArray at the same.
