[SOLVED]Stuck, Need Help: A Class Array In Script Code? (Current Builds But Crashes On Running)

UnknownUser

Hi,

Been trying to get this working for a couple of hours. Stuck...please look at script code below and provide a solution: Thanks!

Below script code builds, but it crashes when run on line # 45

The error seems to suggest Sprites[index] exists but Sprites[index].SpriteImage is undefined. If you put a breakpoint there and inspect Sprites[index], I think you'll find no array called SpriteImage

Ok, have below, but it still crashes when run?:

	var SpriteColorRed = []
	var SpriteColorGreen = []
	var SpriteColorBlue = []
	var SpriteColorAlpha = []
var Sprites = SpriteClass.new()

Here's what's happening. You are trying to call append in an element of the SpriteImage array.

# There's no array at the index of SpriteImage.
Sprites.SpriteImage[index].append(Sprite.new())

What you need to do is call append directly on SpriteImage.

Sorry, I don't understand. Can you show an example?

We got it, thanks!
