Error use of unassigned local variable
Hi,
i need to fill a array with a for loop for each item in an xml file.
Within in the forloop by the first line it's says "use of unassigned local variable items" I tried everything and cannot find a solution.
Anyways here the code:
public Item[] loadXmlFile(string filename,string tagname)
{
Item[] items;
TextAsset file;
file = Resources.Load(filename) as TextAsset;
XmlDocument xmlFile = new XmlDocument();
xmlFile.LoadXml(file.text);
XmlNodeList listNodes = xmlFile.GetElementsByTagName(tagname);
for (int i = 0; i <= listNodes.Count; i++)
{
items[i].itemName = listNodes[i].Attributes["itemname"].Value;
items[i].prefab = (Transform)Resources.Load(listNodes[i].Attributes["prefab"].Value);
items[i].icon = (Texture2D)Resources.Load(listNodes[i].Attributes["icon"].Value);
items[i].buildCost = listNodes[i].Attributes["buildcost"].Value;
items[i].maxInhab = listNodes[i].Attributes["maxInhab"].Value;
items[i].elecConsump = listNodes[i].Attributes["elecconsump"].Value;
items[i].waterConsump = listNodes[i].Attributes["waterconsump"].Value;
items[i].xpAdd = listNodes[i].Attributes["xpadd"].Value;
items[i].itemText = listNodes[i].Attributes["itemtext"].Value;
}
return items;
}
You should initialize the array with a specified number of elements.
Use: Item items[] = new Item[sizeHere];
Then you can populate the array.
Yes , that gets rid of the unassigned error now it gives me a null reference exception again at the same line (line 12) ("Object reference not set to an instance of an object). I feel dumb today i really have no clue whats going on here ?
Maybe I'm being silly but just like the error says "items" is not initialized?
//this will be before the for loop
items = new item[listNodes.Count];
And by the way, since 'i' starts at 0 you dont go to "i<=listNodes.Count" but to "i< listNodes.Count" right?
Yes it comes before the for loop. if the array size is 5 and you use i=0 < then it will loop five times, if you use i=0
