Setting a new runtime class variables gives Null reference

Questions & Answers

I have a class:

class aPart
{
	var partName : String;
	var partDescription : String;
	var partIcon : Texture2D;
	var partIconRect : Rect;
}

public var partList = new Array();

During runtime, i need to make a new part and add it to an array of parts i have:

function storeNewPart(partToStore : String)
{
	var newPart : aPart;
	newPart.partName = partToStore; //null reference here, why?
	newPart.partIcon = Resources.Load(partToStore);
	partList.Add(newPart);
	ArrangeParts();
}

I am an artist turned scripter, and have been stumped by this for several hours now. I can not find any good solution around this. What is the correct way to create a new part on the fly and add it to my partList?? Thank you for taking a look :slight_smile:

You didn’t initialize newPart, you only declared it; it’s null (hence the error).

var newPart = new aPart();
