How to determine what type of class is being interated through in an array of multiple classes
I have an inventory script that contains multiple types of item classes, for example Weapon, Ammo, or Armor and I'm trying to iterate through the inventory and discover what type of class is currently being iterated through:
class Weapon { var Icon : Texture; var Name : String; var AmmoLoaded : String; }
class Ammo { var Icon : Texture; var Name : String; var Quantity : int; }
function OnGUI() { for( var i = 0; i < inventory.length; i ++ in inventory ) { var currentItem = inventory[i]; if (currentItem == Weapon) GUILabel( Rect(0,0,20,20), currentItem.Name); if (currentItem == Ammo) GUILabel( Rect(50,0,20,20), currentItem.Name); } }
Here I'm trying to get each type of item to appear in a different place on the screen, but even if I print(currentItem) and it prints out "Weapon" or "Ammo" in the console, it doesn't understand if (currentItem == Weapon).
Use the is keyword:
if (currentItem is Weapon)
Edit (js):
if ((currentItem as Weapon) != null)
or
if (currentItem.GetType() == Weapon)
Sorry but this is throwing an exception: expecting ), found 'is'.
I think the 'is' keyword is for C# and not javascript?
Oh sorry, I misread the above as c# for some reason. I'll add in some JS examples that I can think of
